多年生的恶性杂草——冰草,既与果树争水争肥,又可孳生病虫,对果树危害甚大。多年来我场采用茅草枯、扑草净等农药及农业措施消灭果园冰草,都收效不大。每年平均40厘米高的冰草将果树团团围住,严重影响果树生长及果品质量。 1980年我场从江苏镇江江南化工厂引进了一种新除草剂——草甘膦,进行除草试验,效果很好。草甘膦又名镇草宁,化学名称为N-膦酸甲基甘氨酸,分子式为HOOCH_2NHCH_2PO(OH)_2,是一种新型广谱内吸传导性除草剂,靠植物进行光合作用的绿色部分吸收药
Perennial malignant weeds - ice grass, both competing with the fruit trees fight fertilizer, but also breeding pests, fruit trees are very harmful. Over the years I use thatch dry, promethazine and other agricultural pesticides and agricultural measures to eliminate orchard grass, are ineffective. The annual average height of 40 centimeters of grass will be surrounded by fruit trees, seriously affecting fruit tree growth and fruit quality. In 1980, we introduced a new herbicide, glyphosate, from weijiang chemical plant in Zhenjiang, Jiangsu province, for weeding test, and the result was very good. Glyphosate is also known as Zhencao Ning, its chemical name is N-phosphonic acid methylglycine, and its molecular formula is HOOCH_2NHCH_2PO (OH) _2. It is a new broad-spectrum systemic herbicide that absorbs the green part of photosynthesis by plants medicine
