There are fresh tricks in the production of winter jujube
After the jujube has become a garden, how can it be high quality and high yield for successive years, and the fruit growers are very concerned. The existing few offers are for reference.
1, fertilize fertility, enhance tree vigor. The first is to enhance the supply of various essential elements of the tree, especially for the construction of land, but also to increase the investment of NPK fertilizer. To increase organic fertilizers, pay attention to irrigation and drainage, and maintain a moderate degree of lyrical, it is necessary to pay attention to the timely spraying of new high-fat membranes to ensure the effectiveness of fertilizer, and effectively promote the strength of the tree and enhance its disease resistance.
2, cut the entire tree, strong flowers and promote fruit. It is necessary to promptly clear off the diseased branches and dead branches, scrape the diseased skin, and apply anti-corrosion film on the wounds of their knives and scissors to promote wound healing and prevent infection by pathogens. In the flower bud stage, young fruit stage and fruit expansion stage, spraying strong fruit turmeric, increasing fruit pedicle, increasing nutrient delivery, preventing falling flowers, improving pollination ability, increasing fruit setting rate, accelerating expansion rate, and ensuring fruit quality high yield.
3, promote flower differentiation, balanced fruit rate. The annual size of the tree bearing fruit causes the tree to bear an imbalance, affecting both the equilibrium income and the orchard's tree health. To increase the flowering rate of jujube in each year to 20%, ring brush to promote Kao 2 once; after 30-35 days and then to promote Huawang 2 once again, you can greatly promote flower bud differentiation, increase flowering fruit setting rate, and suppress shoot madness. Long, thoroughly balanced size years.
4, pest control disease, safety trees winter. Insect pests can make the tree weak, disease resistance is poor, the virus is easy to infect, according to plant protection measures spraying insecticide, and at the same time adding a new high-fat film to enhance efficacy; late autumn and winter, to brush tree maintenance generals, do a good job Winter and cold preparations for gardens and trees. It is necessary to increase fertigation and enhance soil moisture, ensure nutrient supply to the tree, and ensure the robustness of the tree, so as to lay a foundation for the increase in high yields in the coming year.
