| 摘 要： | 田间药效试验结果表明:施用48%灭草松水剂对移栽稻田中杂草的防效显著且持久,施药60 d后,对鸭舌草、异型莎草和碎米莎草的综合防效仍保持在80%以上,且鲜重防效和密度防效一致;将杂草防除后,水稻田间中下部的透光率显著提高,离地50 cm处的透光率由4.38%提高至10.42%～12.82%;各处理区杂草的水、肥含量亦显著降低,稻谷产量明显增加。48%灭草松水剂施用剂量以每公顷936～1440 g为宜。

| Abstract: | The results of field trial indicated that 48% bentazone aqueous solution had significant and lasting control effect on the weeds in the transplanted rice field,the overall control effects against Monochoria vaginalis,Cyperus difformis and Cyperus iria were over 80% on the 60th day after applying this herbicide,and the control effects against the fresh weight of the weeds were consistent with those against the density of the weeds.The light penetration rate(LPR) in the middle part and bottom of the transplan... |
