What are the technical points of apricot tree pruning in summer?

1. Remove sprouting

That is to say, after germination in spring, the densely crowded buds or twigs that are not suitable in position and excessive in number will be erased in time to reduce nutrient consumption and make the remaining branches obtain sufficient nutrition and light. This method is mostly used for young trees. It is better to wipe teeth early, and the length of tender shoots should not exceed 3-5 cm. At this time, the branches have not yet lignified, and the wounds caused by them can be easily wiped off by hand; when the old trees are renewed, many useless twigs are also easy to sprout near the scissors and saws, and they should also be wiped off as soon as possible.

2, pull branches

Some varieties of young trees, easy to shoot some vigorous growth of upright branches, resulting in crown does not open. For this kind of branch, after the sap flows to the bud before, pull it into a certain angle with a rope to ease the growth, promote the fruit branch, and bear fruit early. The angle of pulling branches should not be too large, preferably 45-50 degrees. If the angle is too large or it will be erected on the back, it will still flourish and affect the flowering and fruiting.

How to manage apricot trees after harvest?

1. After apricot harvest, weeding should be combined, and the whole garden should be tilled once, and the general tilling depth is about 10 cm. Before defoliation, apply base fertilizer deep ploughing, the depth is 30~40 cm.

2. Fertilization should be applied early after apricot harvest, especially for trees with weaker tree vigor and more fruits in the current year, so as to make up for the consumption of nutrients in the tree body. Apply organic-inorganic compound fertilizer once immediately after picking apricot fruit, apply organic-inorganic compound fertilizer according to age and fruit yield of the year, and then water.

3. Spraying 0.3% potassium dihydrogen phosphate and 0.2% urea + new lipid membrane to increase nutrient accumulation and flower bud quantity and quality.

4. At the beginning of October, apply base fertilizer, mainly high-quality farm manure, mixed with a small amount of compound fertilizer. Generally, 30~ 50kg farm manure and high nitrogen and high potassium sulfate compound fertilizer shall be applied to each fruit tree at the beginning of 5~6 years old, and farm manure and high nitrogen and high potassium potassium sulfate compound fertilizer shall be applied to each fruit tree at the peak fruit stage, and watering shall be carried out immediately after application.

5, after the apricot harvest to timely irrigation of the first water, so that the soil moisture is most conducive to the growth and development of apricot trees, this watering can ensure the normal differentiation of flower buds and branches of growth, aging and maturity. If it rains during this period, you can not water, but also pay attention to drainage. In the place where conditions are available, water should be poured once before freezing, and the whole garden should be sprayed with tree protection generals to ensure the safety of apricot trees through winter.
