Apricot tree high yield cultivation

1. The construction site should be a sandy loam garden that is rich in fertile soil, capable of irrigation and drainage, and is 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. Planting density is 34-5 meters in plains and 23-4 meters in hilly mountains.

2, soil and fertilizer water management combined with autumn Shiji Fei every other year or inter-depth deep, depth of 60-80 cm. 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, and 2000-3000 kg can be applied per acre. Generally, 3 top dressings are guaranteed throughout the year: (1) fertilizers before flowering, mainly nitrogenous fertilizers, with 0.25 kg per plant; (2) expanded fertilizers, mainly compound fertilizers with 0.5 kg per plant; (3) compound fertilizers with high nitrogen content after post-harvest fertilizers The main fertilizer is 0.25 kg per plant; (4) The foliar fertilizer is sprayed, and the weak flower tree 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, plastic trim apricot using the tree shape of the main branch of natural happy shape, free spindle shape, sparse layer of small crown and so on. 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. In case of adverse weather such as low temperature, rainy weather, strong wind, etc. during flowering and flowering management, 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 per metre is controlled at 2500-3000 kg. Strong Wang branch should keep more fruit, weak branches should be less stay, leaving the fruit spacing of 5-8 cm is appropriate.

5, harvesting and packaging for long-distance transportation of fresh food or used as canned fruit, apricot fruit, should be harvested at eight mature. 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. Use small packaging when packing, generally about 5 kg. Storage temperature is about 0°C and relative humidity is about 90%.

6. Pest control In the early spring, 3-5 days before germination, the whole tree was sprayed with 5 degree lime sulfur 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 fluid, then use 5 degrees lime sulfur to disinfect the wound, and then apply wax or coal tar protection to prevent and cure gum 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.
