2011—2014年进行了修剪时期对核桃生长发育及坐果率影响的试验,结果表明,冬季(休眠期)修剪不仅对核桃生长发育和结果没有不良影响外,而且坐果率比春、秋修剪分别提高22.4%~28.4%;667m~2产量及收益均比春、秋季修剪分别提高了26.7%~35.9%,经统计分析:不同修剪时期修剪对核桃的坐果率和产量的影响极端显著,该研究为核桃更进一步提高坐果率达到丰产、稳产、提质增效提供理论依据和技术支撑。
The results showed that the winter (dormant) pruning not only had no adverse effect on the growth and development of walnut, but also increased the fruit setting rate more than that of the spring and autumn pruning 22.4% ~ 28.4%. The yield and yield of 667m ~ 2 increased by 26.7% ~ 35.9% than the spring and autumn pruning respectively. According to statistical analysis, the effect of pruning on the fruit setting rate and yield of walnut was significant at different pruning times Walnut to further improve the rate of fruit set to achieve high yield, stable yield, improve efficiency and provide theoretical basis and technical support.
