摘　　要：为明确75%氯吡嘧磺隆水分散粒剂对番茄田间杂草管理的重要性,采用田间试验和仪器测定分析的方法,观察了药剂对番茄田间主要杂草的控制效果、杂草防除后田间的透光率和施药后番茄产量的影响。结果表明：施用75%氯吡嘧磺隆水分散粒剂能有效控制番茄田间主要阔叶杂草和莎草科杂草的危害;药剂处理后对番茄田间香附子、野苋菜、马松子、铁苋菜的综合密度防效为82.52%~95.78%,综合鲜重防效为83.53%~96.09%;药剂处理后番茄田间中下部的透光率亦显著提高,并能有效改善田间光照条件,增产效果显著。The purpose of this paper was to evaluate the importance of weed control by 75% halosulfuron-methyl WG in the farming management of tomatoes was fields.The effect of 75% halosulfuron-methyl WG on the main weed control and the subsequent light penetration rate（LPR） at different heights of fields,as well as the yields of tomato were studied by means of field experiments and instrument mensuration.The results showed that：75% halosulfuron-methyl WG had significant control effects on the main broad leaf weeds and Cyperus weeds.The overall control effects of Cyperus rotundus,Amaranthus retroflexus,Melochia corchorifolia,and Acalypha australis were from 82.52% to 95.78%,and the overall quantity control effects were from 83.53% to 96.09%.The LPR in the middle and bottom of the tomato fields was significantly improved after the weed control.With weed control,the situation of light penetration rate was markedly improved,which resulted in a prominent enhancement of rice yield.
