摘 要:为探索持续实施综合技术措施对达到盛果期的三台核桃(Juglans sigillata)树体生长及结实状况的影响,采用综合技术措施与粗放管理,对2块16年生核桃林进行观测对比研究。结果表明,实施综合技术措施样地的树高、地径和平均果枝率的年度增幅比对照高。不同栽培技术措施树体的树高、冠幅、抽枝数、结果枝数和落果率差异极显著。不同栽培技术措施的单果重差异显著;出仁率、平均单株产量和单位冠幅产量差异极显著。持续实施综合管理技术措施,核桃的树体生长、结实性状、果实性状和单位面积产量均优于粗放管理,当核桃园进入盛果期后产量可达870 kg·hm^-2·a^-1,效益非常显著。In order to explore effects of integrated technical measure on growth and fructification of Juglans sigillata trees in full productive age,two 16-year-old walnut forests were observed and compared by integrated technical measures and extensive management,respectively.Results showed that annual increments of tree height,ground diameter and average rate of fruit to branch in sample plots with integrated technical measure were higher than those of control group.There were extremely significant differences in tree height,crown width,number of shoots,number of fruiting branches and dropping rate with different measures.There were significant differences in single fruit weight and extremely significant differences in kernel rate,average yield per plant and yield per crown with different measures.Tree growth,fruiting traits,fruit traits and yield per area of J.sigillata with integrated technical measure were better than those with extensive management.When entered full bearing period,yield could reach 870 kg·hm^-2·a^-1 with good benefit.
