结果母枝留量对莲花栗发枝成花、叶片营养及产量品质的影响

Effects of mother branch retention on flowering,leaf nutrition,yield and quality of‘Lianhuali’Chinese chestnut

以10年生莲花栗为材料,研究了修剪方式对板栗叶片营养、产量等的影响。结果表明,不同结果母枝留量修剪提升了莲花栗的结果枝数量、雌花数量及栗实品质等。其中,留1个结果母枝修剪处理板栗结果枝数量、雌花数量、栗实可溶性糖含量均明显增加,与对照相比分别增加了85.4%、98.0%、19.2%,板栗花期叶片中大量元素氮、磷和还原糖等含量均明显增加。

With‘Lianhuali’Chinese chestnut,to study the influence of pruning method on foliarnutrition,yield.The results showed that the pruning of different fruiting mother branches increased the number of fruiting branches,female flowers,and chestnut fruit quality of‘Lianhuali’Chinese chestnut.Among them,the number of fruiting branches,the number of female flowers and the content of soluble sugar of chestnut fruit were significantly increased by 85.4%,98.0%and 19.2%,respectively,compared with the control.The contents of nitrogen,phosphorus,and reducing sugar in the leaves of Chinese chestnut were significantly increased.
