浅析不同修剪强度对油茶生长和结果的影Ⅱ向

通过对油茶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的萌发和生长，进行轻剪的标准枝，其平均新抽梢数为533条、新梢平均梢长1428cm、平均开花枝数3．58条、平均结果枝数242条，此四项指标均极显著高于中剪、重剪及不修剪处理组；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加而呈递增趋势，但整条标准枝上的结果总量仍属轻剪处理纽为最高；修剪强度对各指标的关联序为：新梢平均基径〉平均结果枝数〉平均开花枝数〉平均新抽梢数〉新梢平均梢长〉结果枝平均坐果数。

through the study of the different strength of oil-tea spring tip pruning process, the results showed that the light pruning the most beneficial to the germination and growth of new shoots, light cutting standard branch, its average new pin number to article 5.33, tip tip on average 14.28 cm long, open flowers per article 3.58, the average fruit number 2.42, the four indicators were significantly higher in cut, cut, and no pruning treatment group; Each treatment group rates and standards of new tip fruit rate is increased with the increase of cutting intensity increasing trend, but the result of the entire standard branches is still in the amount of light cutting processing group for the highest; Pruning intensity of each index of correlation order is： the new pin number average average fruit base diameter 〉 〉 average number of open f]owers） average new smoke tip number average tip length 〉 〉 new tip fruit fruit number on average.
