去年秋播以来江苏省持续干旱,后期又遇低温天气,导致冬前化除面积较小,并且除草效果不理想。与常年相比,今年田间杂草萌发推迟,生长量较小,但仍有部分田块草量较高。近期气温回升较快,田间杂草即将进入萌发与生长高峰期,各地应抢抓当前有利天气和草小有利于防除的关键时期,及时开展春季田间杂草防除工作。 Since the autumn of last year, there has been a continuous drought in Jiangsu Province and low temperature in the late part of the year, leading to a smaller area for pre-winterization and weeding effects are not satisfactory. Compared with the perennial, this year weeds postponed the germination, growth is smaller, but there are still some fields of grass higher. The recent temperature rise quickly, field weeds about to enter the peak of germination and growth, all localities should seize the current favorable weather and small grass is conducive to the prevention and control of the critical period in a timely manner to carry out spring field weed control.
