Last Updated: 2024/11/05, 1. Fertilizer and water management. Base fertilizer is applied every autumn. Base fertilizer is mainly livestock manure, compost, cake fertilizer and other organic fertilizer, properly mixed with some nitrogen, phosphorus, potassium fertilizer. After covering plastic film, fertilizer is no longer applied, and 0.3% urea plus 0.2% compound micro-fertilizer and 0.3% potassium dihydrogen phosphate are sprayed once after fruit setting and hard core period. Drip irrigation pipes are installed in the shed to water reasonably according to the soil moisture. Watering should not be too much, lest the new shoots will flourish and cause physiological fruit drop. two。 Plastic surgery and trimming. The "Y" shape pruning is dominated by lateral branches (the main branch angle is 70 degrees to the left.

1. Fertilizer and water management. Base fertilizer is applied every autumn. Base fertilizer is mainly livestock manure, compost, cake fertilizer and other organic fertilizer, properly mixed with some nitrogen, phosphorus, potassium fertilizer. After covering plastic film, fertilizer is no longer applied, and 0.3% urea plus 0.2% compound micro-fertilizer and 0.3% potassium dihydrogen phosphate are sprayed once after fruit setting and hard core period. Drip irrigation pipes are installed in the shed to water reasonably according to the soil moisture. Watering should not be too much, lest the new shoots will flourish and cause physiological fruit drop.

two。 Plastic surgery and trimming. The "Y"-shaped pruning is mainly lateral branches (the branch angle of the main branch is about 70 degrees). The upper dorsal branches are properly thinned or utilized, the mediocre branches are long, the drooping branches are retracted, and the dense branches, disease and insect branches and dead branches are cut off.

3. Artificial pollination. Due to the high humidity of the air in the shed, the pollen is not easy to spread, so it is necessary to put a box of bees to pollinate or pollinate artificially.

4. Control of major diseases and insect pests. Spraying 700 × 800 times carbendazim 10 days after anthesis to control scab. Apply 2-5-fold omethoate ring before germination or spray 4000-fold imidacloprid plus 2000-fold fenvalerate after germination to control aphids and control almond bees. Before germination, 50-fold oil emulsion plus 150-fold furan was sprayed to control scale insects.
