稗草是分布最广的杂草之一,几乎世界上所有稻田都有稗草混生。新疆稻田稗草特盛,如农八师23团警卫二连和石河子人民公社,田间混杂度一般在30％以上,种子中混杂的稗粒平均连50—60％以上。 消灭稗草的有效辨法,国内外都推荐深水淹杀,自治区农民也有这个习惯。但因技术水平不同,效果也不一致,为了探求正确的淹稗技术,我们在农八师23团警卫二连和石河子人民公社淹稗期间作了试验,初步得出下列结果。
Barnyardgrass is one of the most widely distributed weeds, and barnyardgrass is mixed in almost all paddy fields in the world. Xinjiang barnyard grass Thyssenlichters, such as the 23rd Group of Agricultural Bates division two guards and Shihezi People’s commune, the field of mixed degree is generally above 30%, the seeds mixed with even more than 50-60% of barnyardgrass. Eradication of barnyardgrass effective identification method, both at home and abroad are recommended deep-water flood, autonomous regions farmers have this habit. However, due to different technical levels, the results are inconsistent. In order to explore the correct technology of flooding barnyardgrass, we conducted a test during the invasion of barnyardgrass by the No.12 Group of Nong Bazhong Group 23 and the Shihezi People’s Commune. The preliminary results are as follows.
