The dormancy period of jujube trees refers to the time period from when the jujube trees fall from the autumn to the sprouting period in the spring of the following year. During this period, the jujube trees are dormant from the outside, but the internal life activities are still in progress. Compared with ordinary fruit trees, early deciduous trees, late buds, and longer dormancy periods make management of the dormancy period of jujube trees more important. In the dormant period, the farmers should do the following work: I. Clear the garden in time. Jujube rust, green-lipped iridescent grasshoppers, and date moths and other pests are overwintering in litter or weeds under trees. Therefore, after jujube defoliation, the jujube garden should be cleaned in time, and the litter, rotting fruit and weeds in the garden should be cleaned up and burned or buried deep underground. Second, Zaoyuan ploughing. Generally combined with base fertilizer. The depth is 15-20 cm. Autumn plough can be used for soil conservation, eradication of weedy roots and root weeds, and reduction of nutrient consumption, which is conducive to winter snow infiltration and increase soil moisture content. Turn over the tree. Combine the Zaoyuan ploughing, dig worms and insects. Peach fruit borer, jujube steppe, peach moth, date moth, etc. have the habit of focusing on wintering in the soil around the trunk. After the soil is frozen and thawed, the overwintering insects and moths are collected and concentrated to eliminate, which can effectively reduce The number of insect populations in the coming year. Third, scrape the old skin. The scrapings are carried out after defoliation and before germination. Bark and tree gaps are overwintering sites for pests and diseases such as Ziziphus jujube and Red spider. By scraping the old skin, you can not only eliminate pests but also stimulate tree growth. The scraped bark must be burned or buried deeply. Fourth, winter cut. In order to prevent shear cuts from drying out, winter shearing is usually carried out before jujube sprouting from early March to early April. In combination with winter pruning, the pests damaged by the wax beetle are cut off. For severely damaging branchlets, the overwintering insects on them can be removed with a wire brush, and the overwintering bugs of the yellow thorn moth must be carefully removed. Fifth, spraying pesticides. In the late November and early March of the following year, spraying 3-5 Baume degree lime sulfur in the Zaoyuan can eliminate leafhoppers, scale insects, and pathogens that overwinter in the trees. Six, tie plastic skirt. Before the jujube sprouts, a 6-10 cm wide plastic tape is wrapped around the base of the trunk, and the upper part is reversed, so that it is possible to prevent the page from boring and burrowing. Ъ跚嵛: Α?/P> Seven, base fertilizer. The zaoyuan without previous basal application must be applied during the dormant period. In order to fully decompose high-quality organic fertilizer, can be appropriately applied to some quick-effect fertilizer, and at the same time pay attention to the use of trace elements in fertilizers to ensure that the balance and comprehensive nutrition.
