摘　　要：本试验以3 a生的“清香”核桃树为试验材料,研究穴贮肥水技术措施对“清香”核桃树的营养生长和生殖生长各主要指标的影响。试验表明,与清耕(CK)比较,运用穴贮肥水技术措施,可使“清香”核桃新梢长度增加36.8%,粗度增加26.7%;复叶面积增加22.2%,复叶重增加29.6%;单株结果数增加31.3%,单株坚果重增加37.8%,坚果单果重增加14.7%。穴贮肥水技术值得在缺乏灌溉条件的地区的核桃产业提质增效中广泛推广和应用。This experiment utilized three-year-old"Qingxiang"walnut trees as test materials to investigate the effects of the fertilizer and water storage in holes technology on the major indicators of vegetative and reproductive growth of"Qingxiang"walnuts.The results showed that compared with conventional tillage(CK),the application of the fertilizer and water storage in holes technology increased the length of new shoots by 36.8%,the thickness by 26.7%,the area of compound leaves by 22.2%,and the weight of compound leaves by 29.6%.Additionally,the number of fruits per tree increased by 31.3%,the weight of nuts per tree by 37.8%,and the weight of individual nuts by 14.7%.Therefore,the fertilizer and water storage in holes technology is worthy of widespread promotion and application in walnut production in areas lacking irrigation conditions to improve quality and efficiency.
