为准确掌握草甘膦除草效果,我们于1998年在本司示范果园做了田间试验。本试验的目的是探索药剂除草的效果,以便在生产果园中推广应用。 1.喷布时期 第1次在1998年5月28日～6月1日,第2次在7月30日～8月2日。杂草株高平均为40cm.最高125cm,最低紧靠地面。 2.喷布浓度 用陕西咸阳工农16型喷雾器喷雾。每666.7m~2用41％农达乳剂(草甘膦)200mL,稀释100 In order to accurately grasp the glyphosate herbicidal effect, we conducted a field experiment in our demonstration orchard in 1998. The purpose of this experiment is to explore the effect of herbicides to promote the production of orchards. 1. Spread the first time in the May 28, 1998 ~ June 1, the second in the July 30 ~ August 2. The average weed plant height of 40cm. The highest 125cm, the lowest close to the ground. 2. Spray concentration Shaanxi Xiaoyang workers and peasants 16 sprayers. Each 666.7m ~ 2 with 41% Nongda emulsion (glyphosate) 200mL, diluted 100
