The flower bud differentiation period of Huangpi fruit trees is generally from 65438+February to 65438+1October in the second year. That is to say, if late autumn bamboo shoots are released, the released late autumn bamboo shoots should be fully mature in the middle and late period of 1 1.

From the middle of 10, the weather is getting colder and colder, and the cold weather is not conducive to the aging of autumn shoots. Therefore, if the first autumn shoot is fully mature, then the last autumn shoot will be released before mid-September. In order to make the last autumn shoot sprout as scheduled, it is suggested that rhizosphere fertilization should be carried out properly, and the fertilizer should be quick-acting compound fertilizer. Dig a shallow ditch under the drip irrigation line of the crown of each plant, and apply about 0.3 kg to each plant.

Because the root system is shallow, and the ability of absorbing water and fertilizer is weak, it is advisable to choose a place with fertile soil, loose soil layer and sufficient water before building the garden. After the garden is selected, the preliminary work is mainly to improve the necessary production facilities such as water, roads and electricity in the orchard, and to support the irrigation and drainage system of the orchard, such as building water storage tanks and installing water pipes in the whole garden.

Precautions:

1. The seedlings of wampee can be fixed in the second spring after planting, usually with 3-4 main branches, and then with 2-3 secondary branches at each level, and gradually cultivated into a round crown. The key to shaping and pruning is to dwarf plants and cultivate their round-headed fruit crowns.

2. There are few pests and diseases of seedless wampee, but some pests, such as aphids and poisonous moths, still have an impact. In the daily production process, we should find it early and spray it in time.
