我团位于焉耆盆地北部天山脚下,部分耕地地下水位高,盐碱重,旱作难保苗,故多连作水稻。由于连作,稻田杂草十分严重,尤以稗草为甚。现有的除稗剂如敌稗、除草醚等,易受低温影响,加之早期稗草出土慢,除稗效果不够理想。1979年,我们用50％杀草丹乳剂进行了灭稗试验,1980年又在3,000亩面积上试用。试验和试用表明,杀草丹对水稻很安全,灭稗效果达97％以上,是寒冷地区连作稻田的理想除稗剂。
My regiment is located at the foot of the Tianshan Mountain in the northern part of Yanqi Basin. Some of the cultivated land is high in groundwater and heavy in salt and alkali. Due to continuous cropping, weeds in paddy fields are very serious, especially barnyard grass. The existing barnyard-removing agents such as propanil, weed-ethers and the like are susceptible to low temperature, and in addition, the early barnyardgrass unearthed slowly, and the effect of barnyardgrass is not satisfactory. In 1979, we tested the barnyardgrass with 50% herbicide cream and in another 3,000 acres in 1980. Tests and trials showed that herbicide Dan is very safe for rice, the effect of molting more than 97%, even in cold areas even paddy rice in addition to barnyardgrass.
