Matters needing attention in post-harvest management of apricot trees

After a large number of apricot fruit, consumed a lot of nutrients, and in the face of flower bud differentiation after fruit picking, so need a lot of nutrition supply, then need timely fertilization, supplement consumed nutrients, in order to have sufficient nutrients for flower bud differentiation. But in addition to this, we should pay attention to the following aspects, let's take a look together.

1, pruning

Apricot trees must be pruned once after fruit picking, dry branches and broken branches shall be cut off, branches that are weak and drooping after fruit shall be retracted and pruned, excessive branches in crown shall be timely removed and twisted to inhibit their vegetative growth, and branches without growth space shall be completely removed to avoid unnecessary nutrient consumption. For upright branches, cross branches, overlapping branches, diseased branches and thin branches, they should be cut off in time to save nutrient consumption. For branches with small development angle, it is easy to expand the angle by hanging branches or pulling branches to promote the increase of plant crown width and lay a solid foundation for high yield and high yield.

2. Strengthen soil and fertilizer management

Apricot trees should be tilled and loosened in time after fruit picking. Generally, the cultivation depth is 5-10 cm. Before the plant leaves, combined with deep ploughing, the base fertilizer should be applied. The base fertilizer depth is 30-40 cm. Fruit picking should be timely application of quick-acting fertilizer, each plant can be applied with 0.5 kg urea, watering. The base fertilizer for autumn defoliation is mainly farm manure, with appropriate phosphorus and potassium fertilizer. In addition, apricot trees are not tolerant of waterlogging. When the rainy season comes, we should remove accumulated water in time to avoid infection or root rot. During fertilization, weeds, fallen leaves, rotten fruits and diseased fruits in the orchard shall be cleaned up, buried deeply or burned, so as to reduce the number of diseases and insect pests.

3. Prevention and control of pests and diseases

Apricot trees should be sprayed reasonably according to the actual situation to protect leaves and accumulate more nutrients during the period of high incidence of diseases and insect pests after fruit picking. For aphids can be used to control the speed of killing Ding, red spiders will cause early leaves of apricot trees, affecting flower bud differentiation in the coming year, resulting in low yield in the coming year, can be used to control the mite or abamectin.

4. Spray growth regulator

After apricot fruit picking, paclobutrazol solution can be sprayed for 1-2 times, which can be mixed with low concentration urea solution and potassium dihydrogen phosphate solution to promote flower bud differentiation. It is easy to irrigate frozen water once before soil freezing in autumn and winter to ensure apricot trees survive winter safely.

The above is an introduction to the management precautions after apricot fruit picking. I hope it can help you. If you want to know more about it, please pay attention to us.
