In the winter, the lemon enters the dormant period. In order to achieve high yield and good harvest of lemons in the coming year, it is necessary to manage the lemon fruit trees and orchards in the winter. How should the lemons be managed in winter? Let's introduce Xiaobian to introduce the lemon winter management method.

Lemon winter management method

First, winter leaf protection

Measures to prevent winter and spring leaves are:

1, timely application of fruit fertilizer: the best organic fertilizer application from late October to early November.

2, prevention and control of the leaf miner, rust tick and red and yellow spiders, reduce leaves.

3. Spray the leaves with 0.1% naphthaleneacetic acid or chlorophyll after the autumn shoots are stopped.

4, cover the water, cover the tree plate with straw or film, warm and moisturize.

Second, winter pruning

(1) pruning twigs: mainly cut off the tissue is not full, the leaves can not turn green late autumn shoots; the result is the lack of light after the auxiliary branches; the result of the decline of the drooping branch decline and over dense branches, dead branches, diseased branches.

(2) Sparse large branches: The erect large branches and strong branches with more upper part of the crown should be deleted to prevent the crown from being weak and weak. When the upper or middle of the canopy is too dense, some large branches are thinned to improve the internal illumination of the canopy.

(3) Pruning of Wangshu: The tree is too strong, and there are many strong branches. Some strong branches should be cut off.

(4) Pruning of weak trees: weak branches of weak trees have many branches, and some weak branches are sparse, which improves the fruiting rate.

(5) Pruning of dense planting gardens: When the adjacent canopy crosses the shading, the canopy should be compressed year by year to reduce the canopy, leaving space for the permanent tree to expand and prosper until the postpartum thinning.

Third, the winter clearing garden

Many pests and pathogens overwinter in dead branches, fallen leaves, trees and weeds. They must carefully carry out winter clearing and reduce the number of pests and diseases in the second year.

1. Orchard cleaning: Combine the winter shears to clean up the pests, diseased branches, fallen leaves, rotten fruits and weeds in a timely manner, and burn them out or bury them in depth to eliminate hidden dangers.

2, Pharmacy Qingyuan: in the middle and late December, the whole garden spray method Xia Le 150 times liquid; sodium rosinate 300 times liquid; 1 degree stone sulfur mixture.

3. Scrape the bark: Scrape the bumps, cracks and lesions on the tree with a spatula, then burn it or concentrate it intensively to remove pests and germs.

4, the trunk brush white: not only can prevent freezing damage, sunburn, but also can control pests and diseases.
