摘要
试验结果表明 :免耕田使用灭生性除草剂——— 2 0 %克无踪、1 0 %草甘磷、“农民乐 747”均可取得理想的除草灭茬效果和显著的节本增收作用 ,免耕抛秧比翻耕抛秧每亩每年直接节约翻耕费用和增产稻谷 :2 0 %克无踪为 78元和 6 .5公斤 ,1 0 %草甘磷为 82元和 8.3公斤 ,“农民乐 747”为 62元和 1 8.7公斤。土壤和稻谷送检均未检出除草剂残留。
the experiment results show that the application of herbicides in no-tillage paddy field, such as 20% Gramoxone, 10% glyphosate, Rocket 747, can lead to an expected performance of weed-killing and stubble-cleanup, and to a marked effect of cost-saving and yield-added. In fact, the per mu annual cost saved from tillage and increased rice production are respectively: 78 RMB and 6.5 kg by 20% Gramoxone, 82 RMB and 8.3 kg by 10% glyphosate, and 62 RMB and 18.7 kg by Rocket 747. There is no herbicide residue tested from samples of soil and rice.
