The management of dormancy period in deep-sloped soil jujube tree is critical to the increase of high yield of jujube tree in the following year. Fine winter deep turning can not only improve the physical and chemical structure of soil, but also promote the deep rooting of jujube tree roots, enhance the robust growth of trees, and The diseased leaves, residual fruits, weeds, etc. under the trees in the garden are ploughed into the soil and used as fertilizer. This measure can achieve the purpose of killing insects and overwintering insects and reducing the source of insects.
Timely clean gardens on the jujube garden litter, fruit drop, fruit, fruit and weeds and other objects, should be promptly removed and concentrated burning or buried in a deep fat.
Brush over the trunk and large branches before wintering, paint with a mixture of lime sulfur mixture (formula: lime 10 kg, sulfur powder 1 kg, water 40 kg) brushing, pay attention to plug the old tree hole, can kill insects Sterilization to prevent frost damage to fruit trees.
The overwintering and clearing garden is combined with artificial killing to artificially capture overwintering pests such as codling moths and thorn moths on trees.
Scrape the bark to scrape off rough skin and cracks on the trunk and main branches and destroy them centrally.
The pruning of adult trees is reasonable, and in the winter, the long branches, thin and thin branches, endogenous cross branches, disease branches and senescence branches are mainly removed to maintain the ventilation and transparency of the crown, and to adjust the tree vigor to ensure three-dimensional results. The old jujube tree can be cut short or retracted from the base of the main branch to promote the emergence of new shoots and timely rejuvenation. Pruning can also eliminate a large number of wintering eggs such as green-legged beetles and red spiders. Http://Content/4e576bf2-27ca-4482-9a9a-989556e7449b?cType=2
