提出了在水稻撒播田安全施用丁草胺的措施及剂量。关键在于播种时及稻苗秧针期田面无渍水;而在水稻处于2.5～3.0叶龄时,稻田须有相当于稻株高度1/3～1/2的水层,并保持水层5～7天。如此则能保证既无药害又能保证除稗效果。
Proposed safe application of butachlor in rice sowing measures and dosage. The key point is that there is no waterlogging when sowing and at the surface of rice seedling stage. When the rice is at 2.5-3.0 leaf stage, the paddy field should have a water layer equivalent to 1 / 3-1 / 2 of the rice plant height and keep the water layer 5 ~ 7 days. In this way, it can ensure that neither the pesticide nor the barnyardin can be guaranteed.
