为了摸索硼对柑桔的保果效应,作者于1984年作了柑桔花期喷硼保果试验。试验在丰乐乡团结果园和石滓乡七村果园进行。两园土壤均为紫砂土。选取树势、花质、花量、管理等较一致的8年生枳砧脐橙和枳砧锦橙为试材。在盛花期用千分之一硼砂对树冠喷雾,设清水对照,单株小区,重复三次,调查生理落果后(7月10日)座果情况。脐橙、锦橙两品种花期喷硼保果的效果一致,其座果率分别由对照的3.7％和2.33％提高到7.98％和8.68％,处理与对照间差异极显著。硼是柑桔必需的营养元素,它能促进花粉萌
In order to explore the fruit boring effect of citrus, the author in 1984 made the orange flower spraying boron fruit conservation test. The experiment was carried out in Fengle Township League Fruit Park and Shicheng Township Seven Villages. Two garden soil are purple soil. Select the tree vigor, flower quality, flowering, management and other more consistent 8-year-old orange and orange tree orange lotus aurantium as test material. In full flowering with one thousandth of borax spray on the crown, set water control, single cell, repeated three times to investigate physiological decapitation (July 10) fruit situation. The results of flowering boron spraying on the two varieties of navel orange and Jincheng were the same. The fruit set percentage increased from 3.7% and 2.33% of the control to 7.98% and 8.68% respectively. The difference between the treatment and the control was extremely significant. Boron is an essential nutrient for citrus and it promotes the germination of pollen
