不同修剪强度对无患子生长和结果的影响

通过对无患子春梢进行不同强度的修剪处理,结果表明:轻度修剪最有利于新梢的萌发,进行轻剪处理的标准枝,平均新梢数为5.67条,极显著高于中剪和重剪处理的标准枝,是不修剪处理组的2.73倍。进行中度修剪的标准枝上萌发的新梢,其基径和梢长的生长情况均明显高出不修剪或经过轻剪和重剪处理的标准枝;经轻剪处理的标准枝,其平均开花枝数和平均坐果枝数分别为3.75条和2.58条,较未做修剪处理的标准枝1.33条的开花枝数和0.83条的坐果枝数,分别高出了181.95%和210.84%;较中剪处理组高出了80.29%和63.29%,较重剪处理组则高出了220.51%和180.43%;各处理组标准枝的新梢开花枝率和结果枝率则是随着修剪强度的增强而呈递增趋势;修剪强度对各指标的关联序为:新梢平均梢长新梢平均基径平均结果枝数结果枝平均坐果数平均新梢数平均开花枝数。

Effect of Different Pruning Intensity of Sapindus mukurossi on its Growth and Bearing

By spring shoots Sapindus trim handle different intensity, the results showed ： mild pruning most conducive to germination shoots, standard light pruning branches, the average number of 5.67 shoots, significantly higher than the cut and standard heavy pruning branches, pruning is not treated group 2. 73 times . Standard moderate pruning branches sprouting shoots, its basal diameter and growth were significantly higher than the no longer pruned branches or through a standard light pruning and heavy pruning process ; standard by light pruning branches, the average the average number of open flowers and sit fruiting number 3.75 and 2.58 respectively, compared with the standard branch pruning process without making the number of open flowers and sat 1.33 0.83 number of fruiting branches, respectively, higher than the 181.95% and 210.84% ; compared with the cut up the treatment group and 63.29% 80.29% heavier cut up the treatment group and 180.43~ 220.51%; each treatment group shoots branches open standard squid rate and branch rate is trimmed with enhanced strength and showed an in- creasing trend; pruning intensity associated with each index sequence is.. shoot an average tip length~ shoot an average basal diameter 〉 average results of several branches 〉 fruit bearing branches average number 〉 average number of shoots 〉 aver- age number of open flowers.
