Measures for fertilizer and water management of apricot trees
The main results are as follows: 1. fertilizing young trees in the first year of planting, applying fertilizer with thin application, in order to rapidly expand the crown and form a certain number of flower buds. The first fertilizer was applied when it sprouted after planting, and then topdressing once every 15 ~ 20 days, mainly urea, combined with phosphorus, potash and organic fertilizer. Stop topdressing at the beginning of July and properly control water to facilitate the formation of flowers. Base fertilizer was applied at the beginning of October, mainly organic fertilizer and phosphate fertilizer. In the second year, topdressing was applied once in late February, mid-April and late June, nitrogen fertilizer was applied with phosphorus and potassium fertilizer, and base fertilizer was applied at the beginning of October. Foliar fertilizer is directly absorbed and utilized, saving fertilizer and water, and achieving quick results. It can be sprayed in combination with the control of diseases and insect pests. Generally, 0.2% Mel 0.4% urea solution and 0.3% KH 2PO 4 solution are sprayed many times after flowering, and 0.1% Mel 0.2% borax solution and other trace elements can also be sprayed at flowering stage. Second, irrigation and drainage apricot trees should strengthen irrigation in areas with little rain and in dry seasons. The combination of spring fertilizer and irrigation before budding for the first time can ensure the needs of flowering, fruit setting and shoot growth. The second irrigation is in the hard core period (about 1 month after flowering), when the water demand is larger, coupled with the phenomenon of spring drought, so attention should be paid to watering. The third time was carried out after fruit harvest combined with fertilization to facilitate branch and leaf growth and flower bud differentiation. In addition, covering tree plates and rows with crop straw and weeds from April to August is beneficial to maintain moisture and increase soil fertility. Apricot trees are not resistant to waterlogging, so we should pay attention to drainage in rainy season, especially in flower bud differentiation period from July to August, so as to maintain proper drought, which is beneficial to flower bud differentiation.
