近几年来,献县枣区群众大力推广应用改春施基肥为秋施基肥、改浇三水为四水、改树下粗管为细管、改树上粗剪为细剪的“四改”法,有效地提高了全县小枣产量。改春施基肥为秋施基肥。春施基肥根系伤口不能很快愈合,肥效发挥慢,早春不能被吸收利用,后期又会使新梢二次生长,对花牙分化和果实发育均有不良影响。秋施基肥结合施入部分速效肥,有利于增加树体内养份积累,增强越冬御寒能力,早春能及时吸收营养,促芽早发,中期促树稳长,后期树势不衰。秋施基肥以迟效有机肥为主,可配合施入适量磷肥和少量氮肥,一般每株枣树施有机肥30—50公斤,磷肥1.5—3公斤,尿素
In recent years, the Xianxian Jujube District people vigorously promote the use of spring basal fertilizer to change the base fertilizer, change the water for the three Sanshui, change the tree for the small tube, the coarse cut for the tree cut fine Change "law, effectively raising the county jujube production. Spring base fertilizer for the autumn base fertilizer. Roots of spring basal application of root wounds can not heal quickly, fertilizer slow, early spring can not be absorbed and utilized, the latter will make the second shoot growth, the flower teeth differentiation and fruit development have a negative impact. The combination of autumn basal fertilizer with some quick-acting fertilizer helps to increase the accumulation of nutrients in the tree body and enhance the ability of overwintering in winter. Early spring can absorb nutrients in time and promote early buds and stable growth in mid-term. Autumn base fertilizer to delaying the main organic fertilizer can be applied with appropriate amount of phosphate fertilizer and a small amount of nitrogen fertilizer, the general application of organic fertilizer per plant jujube 30-50 kg, 1.5-3 kg of phosphate fertilizer, urea
