一、研究目的温州蜜柑是我国柑桔北缘地区的主要栽培品种。它具有耐寒、早结果、产量高、品质好的特点。然而,在我省普遍地存在低产问题。例如,淅川上集乡贾沟村林场栽培的六年生宫川早生,平均株产5.2公斤,着果率为1.54％,严重落花落果。除因花器发育不佳授粉受精不良,和幼果期遇高温干旱等原因之外,枝叶生长与开花座果争夺养分是其主要原因。为此,我们运用调节枝条生长极性,抑制营养生长,疏通树冠内膛光照,增
First, the purpose of the study Wenzhou Satsuma citrus is the northern region of China’s major cultivated varieties. It has cold, early results, high yield, good quality characteristics. However, there are widespread low-yielding problems in our province. For example, Xichuan on Jixiang Jia Goucun forest six-year-old students Gongguluan early birth, the average yield of 5.2 kilograms, the fruit rate was 1.54%, a serious loss of fruit. In addition to poor development due to poor flower pollination fertilization, and young fruit in case of high temperature and drought and other reasons, the growth and flowering of fruit and leaves compete for nutrients is the main reason. To this end, we use to adjust the growth of branches polarity, inhibition of vegetative growth, clear the canopy of the crown light, increase
