In autumn, due to the gradual decline in autumn temperatures, water transpiration is relatively reduced, the soil moisture content is relatively stable. But autumn is also one of the important seasons of nursery management. If the cold, pest and disease prevention work well, will play a multiplier effect on the growth of seedlings next year. In view of the climatic characteristics of autumn, we summarized the matters needing attention in the cultivation and conservation of the seedlings in the autumn, and now they are arranged as follows: timely irrigation: the method of taking more time and less in the period of fast growing seedlings. Each irrigation should be filled with irrigation, irrigation, to prevent erosion of seedlings, seedling stems and seedlings. Each fertilizer should be watered immediately, if the days of rainfall, soil moisture better, do not water. In the late growth period, should be appropriate to control watering (in addition to special drought, generally do not need irrigation). If the seedlings are not out of the nursery before winter, we must put a good winter water. Clear weeds: most of the nursery beds covered with plastic film, generally do not have to cultivate, remove weeds can be. When pulling out the weeds, the operation should be careful, do not hurt the seedlings. If the use of herbicides to destroy grass to be tested in order to avoid injury. The ridge and the two sides, to hoe moisture once in each rainfall or irrigation, while removing weeds. The plastic film mulching cultivation, can loosen the soil and reduce evaporation, play the role of soil moisture and drought. Usually after a timely rain or watering weeding. The cultivation should be deepened step by step, but do not hurt the seedlings, do not press seedlings. In order to control the less lateral roots of the cutting seedlings of broad leaved trees, it is necessary to control the buds in time. Waterlogging: autumn rain, once the seedlings subjected to waterlogging stress or water more, it will cause the whole trees with higher water content, once by low temperature freezing, the tree will freeze expansion, resulting in the death of bark cracking. So dig a drain. In addition to special drought, generally do not need to irrigate in the autumn of scientific fertilization: in the autumn to farm manure and compound fertilizer based, no or less nitrogen fertilizer. Topdressing in the growth of seedlings, coniferous tree seedlings in the top 30 days before the cessation of nitrogen fertilizer. Such as excessive nitrogen fertilizer application, it will cause the seedlings in autumn branches long, low degree of lignification, cold resistance decreased.

The lawn plant leaves and roots are strong, depending on the appropriate pruning. Is the law of maximum pruning cut should not exceed 1/3. A leaf is a reservoir of chlorophyll that turns sunlight into new cells, and when the leaves are cut, the grass withers. The lawn to manicured grass, because must follow the rule of 1/3 (or two years after you have to spend money in planting grass), after too long it is difficult to cut, only one way is often cut. The blade is too high and not necessarily developed. Roots and grass species, soil characteristics, rainfall and fertilization. In the spring and summer, the general need to trim once a week, in the summer can be cut every ten days. In general, the summer grass can be properly higher, so you can protect the lawn from high temperature damage. For example, the height of grass is the most healthy height of 6 cm, then when it grows to about 8 cm, it is best not to be able to trim the 9 cm. Different grass species, the growth mode is not the same. High grass should be more grass, otherwise the sun exposure area is too small. Grass can be kept low, to 3 cm can be. If you cut the timing, but the lawn is still messy, it must be a blunt blade. Blunt blade is very destructive to the lawn. Because the wound was torn grass than neat cut grass injury more bacteria is very easy to invade, so after blunt force is often grass lawn of white and gray, one or two days after browned, not timely treatment is often caused by necrosis.
The blade must be worn every ten days and the hob blade can be worn every three months. If the leaves are tough, the grinding cycle should be shortened. Our lawn needs to be sharpened once every week. The newly planted grass is not neat is a normal phenomenon, such as the complete closure of the lawn will naturally become neat.

In accordance with the division of labor and maintenance management system of job responsibility clear green garbage and debris, including garbage, King stone stone, bricks, gravel, leaves, branches, dry ground plate, cigarette butts, scraps of paper etc.. Every morning when the class, first clean up the garbage on the green space. It is strictly prohibited to burn garbage in green space and other places. On the pool, sculpture and garden sketches and green facilities to be cleaned according to requirements, to clean and clean all day green.
Weeding, scarification, soil is an important part of maintenance work. Often the weeds, normal growth can prevent the competition for water, fertilizer, fight for space weeds and turf growth process and the influence on the lawn, the lawn grass seed purity: a conservation to reach more than 97%; three level maintenance to reach more than 95%; three level maintenance of more than 93%. The lawn soil compaction and trample serious areas, should pay attention to drilling ventilation, when necessary, must be spread with sandy loam mixed organic fertilizer, to ensure the growth of neat, uniform, green degree is high, good elasticity and neat appearance. The green flower beds, hedgerow, vertical greening, single planting shrubs and trees to loosen and earth as required. The new green trees and trees planted within 2 years should be loose, earth, rain will be digging and weeding, scarification ditch vertical greening width should be less than or equal to 20 cm, single planting shrub canopy is greater than or equal to 50 cm wide ditch soil should be less than or equal to 20 cm.
According to the growth needs of lawn, Bush and shrubs, flowering characteristics, weather conditions in different growing seasons, different plant species and different ages of water and fertilizer to ensure adequate water and fertilizer. According to the climatic conditions in Shenzhen, the summer is hot and rainy, and the winter is dry, so in the lack of rain season, the daily amount of water to be slightly greater than the transpiration. For water the lawn, especially to the dry season in February second in October, but also make the winter green, so should wash water multi fertilization, and appropriate root fertilization, the lawn to keep the good growth through the dry autumn and winter. Flowering shrubs in the spring and autumn each year, the main fertilizer 2-3 times. Radu and other flowering shrubs due to water control, promote flower bud differentiation, flower bud differentiation to P and K appropriate chase, to spend a long period of multicolor colourful flowers. Trees in the spring and autumn each year, the key fertilizer 2-3 times. Depending on the type of fertilizer and the growth of trees, planting trees and within three years of tree vegetation trees to increase the amount of fertilizer and fertilizer application number properly buried, digging or open ditches, to backfill with enough water, sureness, leveling after fertilization, fertilizer should not exposed. Tree fertilizer cave specifications generally 30 x 30 x 40 cm, a size 30 x 40 cm, digging or ditching position is usually on the outer edge of the crown projection (except trees), each plant dug two symmetrical points or four points, fertilizer to organic fertilizer, compound fertilizer supplement.

Osmanthus tree, Osmanthus fragrans, Oleaceae (Oleaceae) Olea, are evergreen trees, up to 15 meters, solid material, fine texture, in acidic soil or calcareous soil can grow well. Osmanthus tree trees are elegant, blue green leaves, evergreen fragrance, pleasant, neutral tree, sapling resistant shade, middle-aged hi light. Sweet scented osmanthus tree is a very good garden trees and tree species.
Osmanthus tree cultivation techniques, the following information is for reference only
Seed: 9-10 month flowering, fruit ripening in 4-5 months. A blue black, can be cooked in fruit picking, natural shedding. Fruit after composting, to peel after softening, soaking rub to peel, remove clean, slightly dry after sand (sand storage humidity control in hand into a group to let go natural loosen, such water is about 5%). Seed weight of 200-300 grams, kg per kg, germination rate of more than 60%.
Seedlings: nursery should choose fertile, deep soil moisture. Winter or spring sowing, the drill, due to slow growth in seedling stage, so the first year seedlings should be dense, the sowing rate of 30 kg per mu.
Seedling management: Seedling shade tolerance and slower growth, susceptible to harm of anthrax, available Bordeaux prevention, and strengthen the field drainage and shading and fertilizer management. Annual seedling height of about 30 cm, the following year early spring transplantation.
Cutting seedlings: in order to ensure the purity of the varieties are generally used to breed seedlings cuttings. In the 5-6 month, cut trees on the semi lignified branches, cuttings generally stay 2-3 internodes, about 7-10 cm long, with shear plug. Cuttings only leaves two leaves at the top, and the depth of insertion is 1/3 or 1/2. The cutting density was not overlapped with each other. In order to promote the development of early new roots, can use the plug before rooting powder or naphthylacetic acid dipping skewer panicle 3-5 cm. After cutting, fully watering, make the cuttings and soil closely, cover plastic film small Gongpeng, seal, and upper shade net shed.
Cutting seedling management: osmanthus cuttings, water should not be too much, otherwise it is easy to rot. So in rainy season must pay attention to drainage. In the early days of rooting and high temperature and dry weather to spray water in the leaves, keep the leaves often in a wet state. A month after cutting in high shade shed and small plastic arch shed to cover, avoid sunlight penetration. Two months later, sooner or later slightly affected by the sun. In October can be removed gradually increase the light and shade, promote hair root, November demolition of shade shed, greenhouse type cold winter reconstruction.
Cultivation: 3-4 months or autumn transplanting the best, transplanting should not be too deep, and appropriate pruning crown, reduce water evaporation. Fertilizer was applied in winter and July each year. I should pay attention to watering, florescence control watering shoulds not be too wet. Winter pruning, the diseased branches, weak branches and endogenous branches cut off, and cutting short leggy branches.
Pest control: orange leaf disease, leaf spot and angular leaf spot disease occurs or available Bordeaux sweet scented osmanthus, 50% carbendazim WP 1000 times liquid spray. Infestation with red spider, whiteflies, scale insects and pests in distribution, spraying with 40% Omethoate EC 1000 times liquid.

In autumn, the weather is getting cold, reflecting the planting seedlings into cream hearts management another key period, only do peach seedling management in the winter season, to be ready for the next year in the spring, you can get more economic benefits.
Now the Ying cream seedling management compared with the traditional technology of the management technology has been greatly improved, but the fall of the old garden to germinal pest, peach leaf miner and nursery garden near the old pear moth is a major pest of nursery stock. In order to ensure that the bud leaves are not damaged, you can use 40% MEOTHRIN 2500 times liquid plus 25% mieyouniao No. 3 1500 times, or 1200 times the small peach EC, every 10 - 20 days of a jet. Autumn in late September, followed by another three yuan per mu compound fertilizer of 10 kg, combined with watering. Affected by the flood of peach seedlings easy to fall, after the rain to clear drainage. Foliar spray 0.3% - 1.5% to 2 - 3 potassium dihydrogen phosphate. In addition, peach rootstock seedlings with high growth, prone to sprout two branches. Can be divided into 2 - 3 times on the ground within 20 cm of the two branches in a timely manner, do not damage the main stock leaves. The best autumn management, scientific management, Qingzhou sepok peach seedling base cooperatives reflect Frost seedlings can bring great economic heart effect for farmers

Summer is the most exuberant season for seedling growth, while summer is more rain season, high temperature, drought and windy, but often there will be work before or after the first flood Yin dry unstable weather, the weather will give seedlings caused certain pests, spring planting, seedling planting after a while fast germination show branch, but when the seedlings in seedling root damage, and carry their own water and nutrients are limited, in the summer high temperature environment, the need for timely and effective timely and appropriate to the spring planting seedlings supplement water and nutrients, so as to ensure the normal growth of seedlings. The following small sum up how to do a good job in the summer nursery management of several points for your reference:
Irrigation: high summer temperatures, water evaporates quickly, easy to dry soil, seedlings at this time most easily affected by drought. Most seedlings in the summer with little rain in ten days when the best irrigation time, the best time in the morning and evening, when watering, not only to soak the soil, and tree and inclusions (such as dressing trunk rope etc.) are wet. For ginkgo, pine seedling drought resistance, usually without irrigation, while for poplar, willow, Metasequoia seedlings irrigation can increase. For the seedlings to be drained after the seedlings without water, the best depth of the seedbed is more than 25 cm deep groove. Drainage: natural disasters such as typhoon season, garden water to drainage, if poorly drained soils should pay attention to control the number of watering, so as not to rot.
