为了进一步提高文冠果的结果能力,达到丰产稳产的目的,我们利用文冠果萌芽力、成枝力强的特性,对放任生长而失去结果能力的10年生弱树和连续结果的8年生强树,同时采用回缩、疏枝的方法,进行修剪试验。1978年12月和1979年6月先后对剪口下新梢的生长和结果情况作了调查,列表如下:由上表可以看出,近几年失去结果能力的文冠果弱树,经修剪后,剪口下都能抽生出长31.5—37.7厘米,粗0.36—0.48厘米,花序饱满的强壮新梢,并增加结果量为175%。
In order to further improve the ability of Xanthoceras sorbifolia and achieve the purpose of high yield and stable yield, we used the characteristics of germinating buds and twigs of strong and stable branches, ten-year-old weak trees losing their ability to tolerate growth and 8-year-old Tree, at the same time using retraction, thinning method, pruning test. December 1978 and June 1979 successively cut the next tip of the growth and results were investigated as follows: As can be seen from the table, in recent years the ability to lose the outcome of the weak tree, pruning After the notch can be drawn out under the long 31.5-37.7 cm, 0.36-0.48 cm thick, inflorescence full of strong shoots, and increase the amount of results for 175%.
