First, the garden will be deep, 20 cm deep, each 3-4 m wide and 0. 8-1 m deep, with 50 kg of organic fat, such as human urine and hog and cow dung, mixed with lime1-1. 5 kg, calcium perphosphate 1-2kg, cake fat 1-3kg, then continue to go back to the earth, filling up the concrete edges with light seeding, laying down the ground and maintaining close contact with the soil. The post-filled site must be above ground level and must be scarred to the south, with an interface showing 2-3 cm of soil, watering the root until it is wet, and two-3 times thereafter depending on the weather。
4 fertilized water management
4. 1 soil management
4. 1. 1 deep-spread and fertilized soil
In the autumn, in september-october, the soil was projected vertically from the tree canopy to maintain the soil sterilisation; organic fertilizers were applied and water was poured back into the filling。
4. 1. 2 spectrum or grass
In the three years prior to the establishment of the park, it may be appropriate to plant food between low-dry forests or to plant grass; and to cultivate the soil in a timely manner, with vines covered with tree dishes。
4. 1. 3 cultivation and weeding
Weeding is cultivated 2-3 times a year, and the trees are kept clean。
4. 1. 4 peasant
Each time we plant grass weed, we use fruit-tree-breeding soil, which is 5-10 cm thick。
4. 2 fertilisation
4. 2. 1 fertilizer principles
The application of appropriate trace element fertilizer and the rational application of inorganic fertilizers is mainly based on organic fertilizer。
4. 2. 2 fertilizer methods
A. Soil fertilization
Quality citrus lobe diagnosis: 0. 8% - 1. 5% potassium, 0. 12% - 0. 18% phosphorus, 2. 8% - 3% nitrogen, and 0. 7 - 1% potassium phosphorus nitrous application, depending on soil, tree age and tree direction。
B. Leaf-faced fat
The nutritional needs of tree bodies are supplemented by fattening of the leaves, based on the application of 3-4 sapplings at different stages of growth and development, cloud-mass 120 or 0. 2 per cent of potassium phosphate。
4. 2. 3 period of fertilization
At the time of the larvae, one in each of the weeks before the new gestation, six to seven applied throughout the year, mainly on nitrogen, which was suspended in august. As temperatures are expected to decline after november, a single application of base fat is required to improve the resistance of fruit trees to cold and to increase nutrient accumulation. In the case of adult trees, one in a year is applied to a bulge, one in a fertilizer, and one in a fertiliser, mainly organic。
4. 2. 4 fertilization
In the case of a single production unit of 30 kg, a three-dollar compound fertilizer of 1. 5-2. 0 kg was applied in the case of a strong fruit, and a cake weight of 2 kg and urea of 0. 5 kg were applied in the case of a fruit。
4. 3 water management
4. 3. 1 irrigation
Due to the high-temperature dry period of july-september, timely irrigation can be carried out through ditch or drip irrigation。
4. 3. 2 drainage
Draining measures in the left sea to remove silt in a timely manner to prevent flooding in rainy weather。
5 orthopaedic cuts
5. 1 plastic
Through shearing, shears the trunk and skeleton branches of the tree, and shews the tree form into the main dry layer and the natural happy shape。
5. 2 motion
5. 2. 1 teenage
The gestation of the larvae is done in a timely manner, with long and small branches cut short, thereby increasing the canopy, rooting and forming。
5. 2. 2 outcome period
The long branches are short-cut and contribute to the growth of fruit trees; the wiping of branches helps to increase the rate of sitting fruit and improve the quality of fruit; and the retrenchment of branches facilitates the renewal of strength, as well as the cutting of insect branches, weak branches, twigs, long branches and winters at the top。
6 flower fruit management
6. 1 artificially assisted pollination
Poaching tools, such as pencils and brushes, may be used to extract pollen, so that the pollen will fall evenly on the female's column, with only one or two flowers selected for artificial pollination。
6. 2 plumbing fruit
When flowers are blooming, the trunks of the tree are shaken away from the sick buds, the weak buds and the deforming buds, followed by artificial graft to remove the weak branches, appropriate preservation of the strong branches, and, lastly, by the preservation of the flower promotion king no. 2. New high-fat membranes are sprayed at 80 per cent oatmeal. After the second physiological fallout period, the umbilical figs were sprayed once every 10 to 15 days with 800 times the fluid and 200 to 300 mg/l cactin。
6. 3 fruit packs
At the end of the second physiology period, a single-storey white semi-transparent citrus bag containing 15 cm x 15 cm was selected。
7 pest management
The main diseases are haemorrhagic disease, anthrax, yellow dragon disease, ulcer disease, crony disease, green disease, skin disease, etc
The main pests are red spiders, rusty wall lice, wood lice, orange aluminum, pedestals, leaf moths, yellow roll moths, etc。
7. 1 agriculture prevention and control
Timely removal of weeds; regular deep tillage; dry whiteing of trees during winter hours to effectively prevent pests from laying eggs in winter; intensification of field management and water fertilization measures。
7. 2 physical control
Physical control is the use of natural conditions, manual or mechanical equipment to combat pests and pests, or the enticing of luminous pests with light facilities such as frequency-fibreding lamps, which are not only cost-effective but also simple to operate。
7. 3 biological control
Chickens are raised in fruit, which can be insecticidal, and chicken dung can be used as waste fertilizers to increase fattening, thereby achieving double harvests in stereospace。

8 fruit harvest
8. 1 harvesting period
Omnicorn maturity generally occurs in december and can be collected during green ripening if the fruit is useful for storage or canning, etc., and not until the fruit is fully mature if it is used to make orange bread, eat directly or keep seed etc。
8. 2 collection methods
The harvest took place in the middle of the morning between the drying and midday。
9 fruit storage and preservation
9. 1 simple conservation
Using tree preservation methods, when the fruit is essentially mature, a certain concentration of a stable fruit agent is sprayed into the tree body, allowing the fruit to remain in the tree for a short period of time and to be collected in batches。
9. 2 chemical preservation
The harvested fruit is preserved by spraying liquid paraffins with 80 (span80) or tween80 (tween80) emulsifiers on the fruit surface。
9. 3 physical preservation
9. 3. 1 vegetable membranes
Vegetables can be packaged to isolate bacteria with polyethylene and polyvinyl chloride, high density polyethylene, polyethylene, etc。
9. 3. 2 temperature
The freezing of fruit in closed reservoirs can effectively control factors such as gas composition, humidity and temperature。
9. 3. 3 refrigerated conservancy
Putting fresh fruits in cold cells has been effective in reducing the incidence of disease and the rate of fruit decay。
