一、叶面喷施速效肥料 枣树采果后,立即用0.3％～0.5％的尿素和0.4％～0.5％的磷酸二氢钾混合液进行叶面喷肥,以避免提前落叶,提高叶片后期的光合效能,增加树体营养积累,促进花芽分化,减少来年的落花落果。 二、早施基肥 基肥以农家肥为主,采收后要尽早施用。幼龄枣树以环状沟施为主,配合放射状沟施,于树冠投影外围开宽40～50厘米、深40～50厘米的环状沟,把有机肥与3倍的土混合均匀后填入,施后浇水。施肥部位随树冠扩大而逐年向外扩展,并每隔2～3年进行一次放射状沟施,即每株开6～8条宽30厘米、深15～20厘米的放射状沟。成龄树在行间开条状沟或撒施浅刨,然后整地浇水。施肥量一般成龄树株施有机肥50—100公斤,碳铵、过磷酸钙各1～2公斤。10年生以下的枣树施肥量酌减。
First, the foliar spray quick-effect fertilizer jujube tree picking, immediately with 0.3% ~ 0.5% urea and 0.4% ~ 0.5% potassium dihydrogen phosphate mixture of foliar spray to avoid deciduous ahead of schedule to improve leaf late Photosynthetic efficiency, increase the accumulation of tree nutrition, and promote flower bud differentiation, reduce the coming year of falling plums. Second, as early as base fertilizer Manchurian fertilizer, harvested as soon as possible after the application. Juvenile jujube ring dominated by the ring, with radial ditch facilities, in the crown projection on the periphery of the open width of 40 to 50 cm, 40 to 50 cm deep annular groove, the organic fertilizer mixed with three times the soil after filling Into, after the watering. Fertilization site with the expansion of the tree to expand outward each year, and every 2 to 3 years for a radial ditch facilities, each plant to open 6 to 8 width 30 cm, 15 to 20 cm deep radial gutter. Aging trees in the line between the open ditch or spreading shallow shaver, and then cut into the water. Fertilizer amount of general aging tree organic fertilizer 50-100 kg, ammonium bicarbonate, superphosphate 1 to 2 kg. Jujube below 10 years of age to reduce the amount of fertilizer.
