1. Land selection: Plant peach-shaped and DOG-shaped varieties on the plot with deep soil layer, fertile and flat soil, sufficient light and convenient irrigation and drainage, and plant spherical and spindle-shaped egg varieties on the plot with deep soil layer and slightly barren soil. 2. Garden construction: The plant spacing on sloping land is 4m× 4m, and the plant spacing on gentle slope land is 3m× 4m. Before emergence, some shoots and leaves should be cut off. Before planting, the planting holes should be soaked in water, cultivated with water, and then covered with soil to plant grass. 3. Management: topdressing 1 time per month 30 days after transplanting. The principle of fertilization is to apply thin fertilizer frequently. After entering the high-yield stage, topdressing the flower-promoting fertilizer before 1 flowering and at the end of March.

First, land selection.

1. When planting peach-shaped and steamed egg-yolk fruits, flat fertile plots with deep soil layer, sufficient sunshine and convenient irrigation and drainage should be selected.

2. When planting spherical and spindle-shaped yolk fruits, the plots with deep soil layer, poor soil and insufficient water resources can be directly used as planting areas.

Second, build a garden.

1, colonial preparation

(1) When planted on sloping land, the plant spacing is 4m? 4 meters, planting hole 100 cm? 100 cm？ 60 centimeters.

(2) When planting on gentle land, the plant spacing is 3? 4 meters, planting hole 100 cm? 80 centimeters, 60 centimeters.

(3) Planting holes can use green manure, and then spread soil and miscellaneous manure to press green. When planting, 50- 100 kg of manure and 0.5 kg of calcium superphosphate can be added to each soil hole.

2, timely colonization

(1) The planting time is 3-6 months after the new shoots of seedlings mature or before the new shoots are picked.

(2) Seedlings should be transplanted with soil to prevent root damage. If you can't bring soil, you can cut off the thick damaged roots after emergence, then soak them in ABT rooting powder for a period of time, then dip them in yellow mud, wrap them with wet straw and film, and transport them to the field.

(3) It should be noted that some shoots and leaves should be cut off before emergence, and the planting holes should be soaked in water before planting, cultivated with water, and then covered with soil to plant grass.

(4) After planting, we should avoid shaking the roots and keep the soil moist.

Third, management.

1, fertilizer and water management

(1) Xiaoshu

① 30 days after transplantation, adoption? Bo Shi Qin Shi? Topdressing is adopted, and the number of fertilization is 1 time/month. The fertilization rate per plant is 20g urea and10g potassium dihydrogen phosphate.

(2) From September to February of the following year, topdressing 1 time every two months, and the amount of fertilizer applied per plant is 20g urea and potassium dihydrogen phosphate 10g.

(3) From March to August of the following year, topdressing urea 30g and potassium dihydrogen phosphate 15g per plant every month. From September to February of the following year, topdressing 1 time every two months, with 30g urea and 20g potassium dihydrogen phosphate per plant.

④ In the third year of planting, young trees generally begin to blossom and bear fruit. At this time, nitrogen fertilizer should be applied appropriately to accelerate its vegetative growth and pick flowers appropriately.

⑤ In the third year of planting, 50 grams of urea and 0/5 grams of potassium fertilizer per plant per month are applied. From September to February of the following year, topdressing 1 time every two months, and the amount of fertilizer applied per plant is 50g urea and 20g potassium fertilizer.

⑥ Irrigation should be done well during the whole young tree period to ensure its normal growth. In the fourth year of planting, plants can usually enter the high-yield period.

(2) Adult trees

(1) After entering the high-yield stage, topdressing the flower-promoting fertilizer (annular shallow furrow application, the fertilization amount accounts for 25% of the whole year) before the 1 th flowering and at the end of March. At this time, 5 grams of borax, 50 grams of calcium superphosphate, 0/00 grams of urea and potassium sulfate, 50 kilograms of manure washing water and a proper amount of trace element fertilizer can be applied to each plant.

(2) At the beginning of July, Guo Zhuang fertilizer can be topdressing (applied to the radial shallow ditch, and the fertilization amount accounts for 50% of the whole year). At this time, each plant can be topdressing urea 100g, potassium sulfate 150g, calcium superphosphate 150g, 5kg of oil cake and 50kg of fecal water.

③ Mid-October and mid-February of 10 are the peak periods of fruit picking, among which mid-February accounts for 85% of the whole year, and the fruit quality is good. Therefore, during this period, it is necessary to topdressing fruit picking fertilizer, such as digging ditches under the vertical line of crown width, and then topdressing 50 kg manure and 0.5 kg quicklime with foliar fertilizer per plant.

④ Adequate water should be provided after entering the strong fruit stage, and proper water control before flowering can promote flower bud differentiation. After the fruit is ripe, the water supply should be strictly controlled to avoid fruit cracking.

2. Soil management

(1) Mulching can not only increase soil moisture and avoid overgrowth of weeds, but also improve soil physical and chemical properties. What kind of covering material is used? Wooden blue floor? (Leguminosae and Indigofera) are suitable.

(2) according to the growth of young trees, expand the holes and improve the soil. Weeds are lightly cultivated in the tree tray, and the tree tray is covered with grass.

3, plastic pruning

(1) Xiaoshu

(1) Three years before planting, the main purpose is to promote vegetative growth, and the crown should be semicircular. After entering the high-yield period, it should be less sparse and more reserved, and cut lightly and put more.

② In the third year of planting, flower buds began to differentiate. At this time, the buds should be smeared in time to ensure the vegetative growth.

(3) In the fourth year of planting, the middle and upper branches of the crown are cut short in summer to keep the fruit yield at about 5 kg/plant. After each pruning, the 1-2 degree stone sulfur mixture should be sprayed evenly into the crown, outside the crown and inside the trunk in time.

(4) After the fourth year of planting, the yield per mu gradually increased, and the eighth year officially entered the rich period.

(2) Adult trees

(1) Prune 1 time after fruit picking, update the fruiting mother branches in turn, and cultivate solid fruiting mother branches on the main branches and auxiliary branches, wherein the number of fruiting of auxiliary branches accounts for 80% of the total fruiting number.

(2) Cut off dead branches, overgrown branches, ground branches, twigs, pests and diseases branches, shaded branches and retracted transverse branches, and dredge the rows of the crown (spray 1-2 degree sulfur mixture on the crown in time after each pruning), and keep the row spacing at 60-90cm.

③ From April to June (from germination to full flowering), shoot control and flower control should be carried out according to the conditions such as the number of new shoots, the amount of flowers and the tree potential. For plants with strong trees, many flowers and few new shoots, priority should be given to controlling flowers and cutting off too many, too dense and too weak flowering branches or crown branches. For plants with moderate tree vigor, moderate flower quantity and moderate number of fruiting branches, we should mainly control branches, cut off branches with the same fruit stalks outside the crown and 50% new shoots in the middle and upper part of the crown, and erase vigorous summer shoots. For plants with moderate tree potential, few flowers and many new shoots, shoot control should be the main method, and the summer shoots inside and outside the crown should be pruned repeatedly until the full flowering period, and the new leaves should not exceed 40% of the old leaves.

④ Properly spray plant growth regulators, such as? 2，4-D？ (5-10mg/l), gibberellin (5-10mg/l, or 20-40mg/l) and other drugs.

⑤ After two physiological fruit drops, in 12 weeks, the diseased fruit, deformed fruit, top fruit, ground fruit and over-dense small fruit are thinned, and the amount of fruit thinning depends on the variety and tree potential, and at most 2-3 fruits are left in each inflorescence.
