通过安排田间小区试验,研究了金银花生长前3年,夏季修剪和冬季修剪对金银花早期产量和生长的影响。通过分析,夏季修剪对地径增粗的影响较小;在金银花定植的第1年,进行过重的夏季修剪不仅不能增加地径粗度,反而有相反作用,冬季修剪对地径增粗影响显著,即冬季修剪可使金银花主干增粗。相对于不修剪,较轻的夏季修剪和冬季修剪均可显著提高“九丰1号”金银花植株高度,减少发枝数并缩减冠幅;相对于轻剪,较重的修剪使树体被过度削弱,使株高降低、发枝数减少。夏季修剪和冬季修剪均对产量有影响,但冬季修剪对产量的影响更显著,在金银花定植早期(第2年)修剪会使金银花产量降低,且重剪降低程度甚于轻剪,但是当植株生长到第3年,合理的修剪可有效增加金银花产量,且三年产量总和最高。研究表明,金银花早期最为合理的增产修剪方案为冬季轻剪和夏季轻剪处理。
By arranging field trials, we studied the effects of summer pruning and winter pruning on honeysuckle early yield and growth in the first 3 years of honeysuckle growth. Through the analysis, summer pruning has less influence on diameter increase; in the first year of honeysuckle planting, excessive summer pruning not only can not increase the diameter of the diameter, but on the contrary, the effect of winter pruning on diameter increase Significantly, the winter pruning can make honeysuckle trunk thickening. Compared with uncut, lighter summer pruning and winter pruning can significantly improve the height of “Jiufeng 1” honeysuckle plant, reduce the number of branches and reduce the crown; compared with light-cut, heavier pruning makes the tree Being overly weakened, the plant height is reduced and the number of shoots is reduced. Both summer pruning and winter pruning had an impact on yield, but the effect of winter pruning on yield was more significant. Pruning would reduce the yield of honeysuckle in the early stage of honeysuckle planting (the second year) Growth to the first 3 years, a reasonable pruning can effectively increase the yield of honeysuckle, and the highest three-year total output. Studies have shown that the most reasonable early honeysuckle pruning pruning programs for winter light-cut and summer light-cut treatment.
