稻田轮作对水稻病、虫、草害的影响
The Effect of Crop Rotation on Rice Diseases, Pests and Weeds in the Paddyfields
摘要
Abstract
Most of the southern paddy fields currently use continuous cropping system, and pesticides are abused, which caused unfavorable factors on farmland ecology environmental. The field trial was product to discuss crop rotation with good ecological role on reducing disease, pests and weeds, according to the 14 years field location experiments. The results show that paddy field rotation in some extent can reduce disease, pests and weeds. The early maturing rice sheath blight with rotation treatment is 10% lower than continuous cropping treatment on average, the disease index is 0.4% lower; the late maturing rice sheath blight with rotation treatment is 17.7% lower than continuous cropping treatment on average, the disease index is 13.3% lower. The disease incidence and disease index of rice false smut with rotation treatment are lower than continuous cropping treatment. The pests with rotation treatment is much lighter than continuous cropping treatment, the white leaf rates of rice with rotation treatment by Cnaphalocrocis medinalis and Chilo suppressalis are lower than continuous cropping treatment. From the point of view of the growth of weeds, the rotation treatment is weaker than continuous cropping treatment.关键词
