摘　　要：本试验以高接5年生核桃经不同时期和程度疏雄后,对其一年生结果母枝的全氮、淀粉、可溶性糖、蛋白质、水分含量和消耗量进行了分析测定,结果表明疏雄具有节留养分的作用。养分消耗量依疏雄量0%、50%、90%递减,随疏雄时期推迟而递增。本文用系列数据阐明了疏雄增产的机理,为疏雄增产技术提供了理论依据。The experiment was carried out with 5-year-old topworking walnut cultivars, after thinning staminate bud (TSB) at different stages and with different treatments. We taken samples (1-year-old bearing shoot) at forthightly interval, and the contents of total N, starch, soluble sugar, protein and moisture of them and consumption quantity of them were analysed. The results showed TSB has founction of saxing nutrient, saved amount by TSB increased in turn thinning 0%, 50%and 90%, decreased gradually as dalay of thinning stages.In this paper, the anthor, useing series of data expounded mechanism in raising yield as reult of TSB, so as to provide theroretical basis for raising yield technique by TSB.
