| 摘 要： | 吉林省中西部有大片轻碱地,是我省重点开发水田地区。但由于地多人少、草荒严重,再加上早春缺水、碱害死苗,产量偏低,影响了水稻的发展。针对上述问题,自1979～1981年研究总结出:省工、省水、成本低的“轻碱地水稻旱种化学除草体系”。在生产上推广应用,已见成效。本文阐述了“轻碱地进行旱种的除草体系”,解决了碱害与药害、保苗与灭草两大矛盾。并提出了有效可行的措施。三年来已研究出水稻旱种,播前诱发杂草,结合耙地灭草;苗期(水稻立针10%,稗草1～2叶期)用50%杀草丹乳油混加20%敌稗乳油,按0.7斤/亩 1.0斤/亩或0.4斤/亩 0.7斤/亩的配方喷杀;分蘖期再用50%稗草烯乳油混加25%除草醚可湿粉,按0.07斤/亩 0.7斤/亩封闭。简称“耙、杀、封”除草体系。该体系经济有效,切实可行,已为近两年在千亩以上生产实践中所证实,灭革效果均在90%以上,对水稻安全。

| Abstract: | There are a larger areas of light alkaline land in the westcentral Jilin province,where the paddy field are developping.The factores effecting rice production development are more land and less man,weeds are seve-rity,short of water in spring,seedling died from alkaline,so that the rice yield lower.To resolve thes problemes,we carried out this study for three years(1979-1981)and summarized the chemical weed control system in rice sowing in dry land on light alkaline land.This system saved man power,water and costs,and has been adopted widely by production. |
