乙草胺、苯黄隆、甲黄隆混用防除麦田杂草初探

Preliminary Approach on Control Weed inWheat Field by Mixing Tribenuron or Meth-sulfuron-methyl with Acetochlor

本文针对麦田恶性杂草化学防除的困难和绿黄隆及其混配剂在偏碱土壤地上对后茬作物的药害问题，进行了以乙草胺、苯黄隆、甲黄隆混用的初步探索。在黄泥砂土有机质含量１．２７％、ｐＨ值８．４的土壤条件下，乙草胺与苯黄隆混用对硬草、婆婆纳、猪殃殃的鲜重防效达８９．６％；乙草胺与甲黄隆混用的防效亦可达７８．７％；对下茬直接王米、棉花生长安全。

This paper preliminaryly approached mixing ex-press or methsulfuron-methyl with acetochlor and their applyhview of difficulties in control weed in wheat field and prob- lem of poisoning later crops in alkaline soil by using chlorsul-furon and its mixtures,In condition that organic tiiatter con-tent was l.27 percent and that pH was 8.4 inloess-like sandyloum,effec on fresh weight of Sclerochloa kmgiana,Veronicapersica and Galium aparine by mixing express with acetochlorwas 89.6 percent,and that by mixing methsulfufon-methylwith acetochlor was 78.7%, These mixture methods were safeto growth of cntton and corn.
