1, Jianyuan
Select a sandy loam soil with fertile, fertile and drainable soils, and not suitable for gardens, heavy saline-alkali soils, and heavy lands. The pollination tree should be selected to be the same as or earlier than the flowering period of the main cultivar. The ratio of pollinated cultivars to the main cultivars is generally 1:6-8. The planting density of the plains is 3m4-5m in the row and 2m3-4m in the hills.
2, soil fertilizer management
Combining with autumn fertilization every year or interlaced deep plunge, the depth is 60-80cm. In apricot apricots, intercropping is carried out, and the thin apricots can be covered with grass and mulch. In October, in conjunction with the deep-turning of the soil, a fully decomposed organic fertilizer is applied. Each 666.7 m2 can be applied to 2000-3000 kg, and sufficient water is poured after the application. Generally, 3 top dressings are guaranteed throughout the year: (1) Before flowering, the main nitrogen fertilizer is 0.25kg per plant; (2) The expanded fertilizer is mainly compound fertilizer with 0.5kg per plant; (3) The post-harvest fertilizer is compounded with high nitrogen content. The main fertilizer is 0.25kg per plant; (4) The foliar spray fertilizer is used to spray 3%-5% urea aqueous solution before spraying. Apricot should ensure four key waters throughout the year, namely, pre-flower water, hard core water, expanded water, and frozen water. The rainy season should be drained in time.
3, pruning
The tree used in apricot has many main branches, such as natural happy shape, free spindle shape, and sparse layer of small crown. Sapling pruning is mainly based on short cuts. Except for the branches that affect plasticity, the remaining branches are not as sparse as possible. After the plastic surgery is basically completed and the light is affected, it is gradually cleared. As a result, the "branch first" method was used for the culture of the shoots. When the early result tree was pruned, the strong Wang branch was cut 2/3, the mean tree branch was cut 1/2, the weak branch was 1/3 cut, and the weak branches were short cut. During the fruit period, attention should be paid to improving the illumination in the crown and timely updating the rejuvenation results. Drag the branches and the branches with very weak results to remove all the branches, reach the height of the tree and fall down to be happy, and remove the upper branches of the crown. Sparse branches, overlapped branches, and severely blocking light pendulous branches were removed.
4. Flower and fruit management
In case of bad weather such as low temperature, rainy weather, and high wind during flowering, artificial pollination should be conducted. Spray 0.2% boric acid or 0.3% borax at full bloom. Combined with winter shearing and pre-flowering, short and multiple flowering weak branches were used to eliminate excessive flower buds, and artificial flowers pollinated during the flowering period were used to eliminate late-opening inferior flowers. The fruit thinning time is usually 20-25 days after flowering. Thinning of fruit can be done in one go. The output of each 666.7m2 is controlled at 2500-3000kg. Strong Wang branch should be more fruit, weak branches should be less stay, leaving fruit spacing is appropriate 5-8cm.
5, harvesting and packaging
The fruit used for long-distance transportation of fresh food or used for processing canned fruit and apricots should be harvested at the time of ripening. The supply of local or neighboring markets should be harvested when fully mature. The fruit used to process dried apricots, apricot jam, fruit juices, and preserves should be harvested when the fully ripened pulp is not softened. Packing with a small package, generally about 5kg. Storage temperature is about 0°C and relative humidity is about 90%.
6. Pest control
In the first 3-5 days before germination in early spring, 5 Be lime sulfur was sprayed on the whole tree to eradicate the source of overwintering diseases and insects. 10 days after Xie Hua sprayed carbendazim 800 times or mancozeb 800 times to prevent scab. Strengthen soil and fertilizer water management, timely drainage in the rainy season, scrape flow plastics, and then use 5Be lime sulfur mixture for wound disinfection, and then apply wax or coal tar protection to prevent fluidic disease. During the expansion of flower buds, imidacloprid was sprayed 4000-5000 times. After germination, imidacloprid 4000-5000 times liquid and cypermethrin 2000-3000 times liquid were sprayed. After fruit set, the peach pods and almond honeybees could be controlled by annihilation net 1500 times.
