梯田堰边老龄低产花椒树更新改造研究

Deep Pruning of Aging and Low-yielding Chinese red Pepper Growing on Terraced edge

以梯田堰边老龄低产花椒为试材,采用随机区组设计进行不同修剪试验。发现刻芽、中截、重截、疏枝修剪处理均能促进新梢生长,提高叶绿素含量,显著提高花椒单株产量、穗重,增加花椒出皮率。以疏枝处理对花椒新梢生长、果实产量品质影响最显著。平茬更新处理的花椒树的叶色浓绿、叶片肥厚、生长壮旺,果实产量和枝量明显高于对照树,复壮效果明显。

Using aging and low--yielding Chinese red pepper growing on the terrace edge as material, By randomized block design test of different pruning method. Found that engraved bud, cut, heavy pruning, thinning pruning treatments Could pro- mote the growth of new shoots, increase the content of chlorophylll Significantly improve the pepper yield per plant and panicle weight, increase the bark out rate of pepper. The thinning treatment on pepper significantly effect the new shoot growth, fruit yield and quality. Deep pruning processing of pepper tree leaf color , leaf hypertrophy, strong growth, fruit yield and the quan- tity of branches was higher than that of the control trees.
