漳县具有种草养畜的传统习惯,特别是胡耀邦总书记视察甘肃,提出“种草种树,发展畜牧”以来,牧草的种植面积和规模迅速扩大。由于该县气候阴湿,人工草地杂草稠密,长势繁茂,种草的经济效益不高。为了解决这一生产问题,我们在背后河牧草试验站,应用2.4—滴丁酯进行除草试验,为大面积使用化学除莠剂除草,取得可靠的科学数据。一、试验设计与方法本试验在生长第二年的老芒麦种子田中选择较平缓的地段,设置3×6米~2的试验
Zhangxian has the traditional habit of planting grass and livestock. In particular, General Secretary Hu Yaobang inspected Gansu and proposed that the planting area and scale of forage grass expanded rapidly since the proposal of “planting grass and planting trees and developing livestock husbandry”. Due to the county’s humid climate, artificial grass weeds dense, growing lush, grass economic benefits are not high. In order to solve this production problem, we conducted herbicidal tests with 2.4-Butyl Ester on the Behind-the-river Forage Test Station to obtain reliable scientific data for large areas of weeding using chemical herbicides. First, the experimental design and methods In this experiment, the second year in the growth of the edible wild rice field selected relatively flat lot, set 3 × 6 m ~ 2 test
