对温柑叶面喷施铁氰化钾的目的在于提高新叶功能。主要是依据春梢新叶缺绿期的同时出现第一次生理落果,此可能因新叶缺绿光合作用甚微有关,为促使新叶尽快转绿有利光合作用而改善养分供给,以达到提高座果率的效用。一、材料与方法试验在新余市罗坊园艺场进行。用9年生积砧尾张温柑为试材,以单株为区组。分设四个处理:500 ppm
The purpose of foliar application of potassium ferricyanide is to improve new leaf function. Mainly based on the spring green shoots lack of green at the same time the first physiological drop fruit, which may be due to lack of new green leaf photosynthesis is very little to promote the new leaf green as soon as possible to improve nutrient supply to improve nutrient supply, in order to achieve Fruit rate effect. First, the material and method test in Luofang horticultural field in Xinyu City. With 9-year-product anvil tail Zhang Wengan as test materials, single plant for the group. Divided into four processing: 500 ppm
