摘　　要：以8年生‘骏枣’为研究对象,研究枣树在一定水分条件下氮磷钾不同的施肥配比对其产量和生长性状的影响。试验结果表明,在施肥设计水平范围内,过高的氮、磷、钾肥,枣树枣吊结果数、枣果鲜重、单株结果数、产量、净收益没有显著增加;增施氮肥可以促进枣吊生长,但产量、净收益与常规施肥处理比较反而显著降低;适宜的灌水和施肥是枣树高产的基本条件。依据氮磷钾不同施用量与产量回归综合分析得出,在灌水总量为330 m^(3)/666.7 m^(2)条件下,以‘骏枣’果实产量为经济目标时,施氮量26.16 kg/666.7 m^(2),施磷量17.12kg/666.7m^(2),施钾量15.77 kg/666.7 m^(2)为最佳施肥配比。Taking 8-year-old‘Jun jujube’as the research object,the effects of different fertilization ratios of nitrogen,phosphorus and potassium on yield and growth characteristics of jujube trees under certain water conditions were studied.The number of hanging fruit,fresh weight of jujube fruit,number of fruit per plant,yield and net income of jujube did not increase significantly when excessive nitrogen,phosphorus and potassium fertilizer were applied to the soil;Increasing nitrogen fertilizer could promote the growth of jujube,but the yield and net income were significantly lower than those of conventional treatment;proper irrigation and fertilization are the basic conditions for high yield of jujube.According to the comprehensive analysis of different fertilization and yield regression of nitrogen,phosphorus and potassium,und er the condition of irrigation of 330 m^(3)/666.7 m^(2) and taking the fruit yield of‘Jun jujube’as the economic target,the best fertilization ratio is 26.16 kg/666.7 m^(2) of nitrogen,17.12 kg/666.7 m^(2) of phosphorus and 15.77 kg/666.7 m^(2) of potassium.
