本地早是品质优良的耐寒柑桔良种,但其树冠直立,主枝开张角度小,枝条密生,花量大,着果率低。我们曾采用疏枝的办法,仍不易削弱其生长势。1990年5月在本地早(7年生树)盛花期,我们采用拉枝加大主枝开张角度的方法,对提高其着果率收到良好效果。拉枝处理的3株树,平均着果率为5.5％;未拉枝 As early as the local quality of the cold-resistant citrus varieties, but the crown upright, the main branch opening angle, dense branches, spend large, low fruit rate. We have adopted the method of thinning branches, still not easy to weaken its growth potential. In May 1990, at the early flowering stage (7-year-old tree) in the local area, we adopted the method of pulling branches to increase the opening angle of the main branches and received good results in improving the fruit setting rate. Pulling the branches of the three trees, the average fruit rate of 5.5%; not pull the branches
