王海公社代宫果树队在鸭梨成熟期将同株一齐采收法改为同株分期选摘法,对高产稳产起了一定的作用。该果树队共有四十年生梨树75亩,连续5年平均亩产7,400斤以上,其中1977、1978年平均亩产超8,000斤。一、怎样进行同株分期选摘? (一)多留果是增产的基础。在疏果时,壮树采用同株分期选摘法可比同株一齐采收法适当多留果。但弱树不可多留果,否则单果增重慢,达不到早采收所要求的标准。 (二)采收开始后,按照标准要求选摘大果,留小果,以延长小果生长期。一般可分两次采收。
Wanghai Commune on behalf of the Palace fruit tree team in the pear ripening will be the same strain recovery method to the same staging phase pick law, high-yield stable play a certain role. The fruit tree team has a total of 40-year-old pears 75 acres, for 5 consecutive years an average of 7,400 pounds per mu, of which 1977,1978 average yield over 8,000 pounds. First, how to choose the same staging? (A) more fruit is the basis for yield. In thinning, strong tree staging using the same staging method can be more than the same strain harvest appropriate to stay fruit. However, weak trees can not stay fruit, or fruit weight gain slow, fail to meet the standards required for early harvesting. (B) After harvesting, according to the standard requirements of large fruit picking, leaving small fruit, in order to extend the growth of small fruit. Generally can be divided into two harvesting.
