How to plant apricot
As an economic fruit tree with edible fruit, branches as fuel and wood as furniture, apricots are also widely planted in various places. So how is it planted? Let's learn about it together.
How do you grow apricots?
1. Propagation and breeding
The planting method of apricot is mainly by grafting, of course, it can also be sown and propagated before the land freezes in autumn and winter. It is mainly the method of transplanting in the north. Wait until the nursery stock grows to a certain extent, cut the sturdy branches for transplanting, preferably about 80cm, so that the survival rate will be very high.
two。 Colonization
Select the sandy loam with deep soil layer and good drainage, and determine the reasonable row-plant spacing according to the local actual situation. Before planting, it is necessary to apply mature organic fertilizer in the pit, let the root system fully stretch, and then add soil firmly. After planting, pour through the water and sink the tree hole.
3. Fertilizer and water
When the new tip grows to about 15 cm, quick-acting fertilizer is applied, and underground topdressing and foliar spraying are carried out alternately. Organic fertilizer and compound fertilizer were applied from the end of September to the beginning of October. After buckling the shed, urea was applied before sprouting, potassium sulfate compound fertilizer was applied after flowering, urea and potassium dihydrogen phosphate were sprayed 10-15 days, and 500 times yield-increasing bacteria could be sprayed at the same time. The seedlings are watered once after planting, and then the amount and time of watering are determined according to the specific conditions.
4. Pruning
If apricot trees want to increase their output, they must be pruned. In fact, apricot pruning is not too difficult, apricot growth, timely cut off diseased branches, dead branches on the line, otherwise it will absorb the nutrition of apricot trees, resulting in trunk loss.
In addition, the fruit expands until the fruit is ripe, pick the heart of the new shoots many times, in order to control the vigorous growth of the new shoots, increase the fruit setting rate and single fruit weight, and erase or twist the upright shoots on the back to prevent the "growing trees on the tree" from deteriorating the internal light of the crown. After the plastic film was uncovered in the first and middle of May, the retraction was combined with branch thinning to adjust the growth balance of the tree and prevent compensatory growth. For young trees and first-bearing trees, winter pruning should take into account both shaping and fruiting. The main branch, lateral branch and extended branch should be cut and put gently, leaving 2/3 of the length of the whole branch to be cut short. The developing branches with moderate growth and relatively open angle should be released slowly to germinate medium and short branches, increase the number of fruiting branches, and retract and culture into fruiting branches in time after flowering or fruiting.
Apricots should be picked in time after ripening, otherwise a large number of fruits will fall, resulting in a reduction in production.
