水稻旱种栽培可节省秧田管理和移栽用工及节约苗期灌溉用水,是旱作农区生产水稻的一项重大农业技术。但是稻田常受稗草的危害,致使水稻减产,甚至毁苗重种。为了防除旱种稻田草害,先后试验和推广过有效的化学除草技术。由于地区、气候、土壤、整地质量、播种时间以及稗草发生密度条条件不同和施药技术上的差别,除草效果也很不一致。近几年来,作者通过氟乐灵对水稻药害、在土
Dry cultivation of rice can save seedling management and transplanting labor and save seedling irrigation water. It is a major agricultural technique for producing rice in dry farming areas. However, paddy fields are often endangered by barnyard grass, resulting in reduced production of rice, or even destroyed seedlings. In order to prevent dry grass and paddy fields, it has tested and promoted the effective chemical weeding technology. Herbicidal effects are also very different due to differences in conditions of area, climate, soil, site preparation, sowing time, density bar of barnyardgrass, and application techniques. In recent years, the author of trifluralin on rice phytotoxicity, in the soil
