玉米覆膜栽培是一项具有保温、保水、保肥、促高产的栽培技术.但由于使用农膜覆盖后,人工除草难于进行,膜内杂草与玉米争肥、争水,降低了地膜玉米的生产效率.为寻求地膜玉米化学除草技术,1992年我们在宜山县德胜镇榄树村进行地膜玉米除草试验,现将结果小结如下.1 试验方法1.1 试验药剂及用量 设23.5%果尔乳油20ml/亩、50%乙单胺乳油70ml/亩和72%都尔乳油150ml/亩.1.2 主要杂草 胜红蓟Ageratum Conyzoides L;野艾蒿Artemisia Lai-andnlaefolia DC;马唐草Digilaria
Maize mulching cultivation is a cultivation technique with heat preservation, water retention, fertilizer conservation and high yield, but artificial mulching is hard to be carried out due to the use of plastic film mulching. In order to seek the film mulching chemical weeding technology, 1992 we Yishan County, Deshengshu tree village weeding mulching test, the results are summarized as follows.1 Test methods 1.1 Test reagents and dosage set 23.5% 20ml / acre, 50% B monoamine EC 70ml / acre and 72% melo EC 150ml / acre.1.2 Main weeds Ageratum Conyzoides L; Artemisia Lai-andnlaefolia DC; Digilaria
