苜蓿是多年生的重要牧草,营养丰富,产草量高。近年来,随着畜牧业的发展,各地种植面积日益扩大。然而苜蓿栽培生产时常遭受杂草危害,严重影响产量与品质。目前对待苜蓿草害,多沿用人工除草,费工费时,收效也低。为寻求苜蓿田化学除草的可能性,探索茎叶处理的适宜除草剂,以期提高经济效益,从1984年开始,我们用两年的时间对草甘膦进行了初步研究。 Alfalfa is a perennial important grass, nutrient-rich, high yield. In recent years, with the development of animal husbandry, planting area has been expanding everywhere. However, alfalfa cultivation often weeds harms the production, seriously affecting the yield and quality. The current treatment of alfalfa grass, and more along with artificial weeding, time-consuming work, yield is also low. In order to seek the possibility of chemical weed control in alfalfa field and explore suitable herbicides for the treatment of stem and leaf, in order to improve economic efficiency, we started glyphosate for two years from 1984 onwards.
