The Cmparing Experiments of Rice Non-Tillage with Seedlings Throwing

水稻免耕抛秧栽培技术能节省生产成本 ,减轻农民劳动强度。免耕抛秧平均 667m2 产 42 5公斤 ,比常耕抛秧每 667m2 增产 9公斤 ,增长 2 .2 % ,667m2 生产成本比常耕抛秧减少 2 7.5— 47元 ,每667m2 收益比常耕增加 1 7.85— 49.

Applying the cultivation technology of non-tillage with seedlings throwing, the production cost of rice can be cut down and the intensity of peasants, labour can be lightened. In this way the average output of rice was 425kg/667m 2. Comparing that of the normal tillage with seedlings throwing, the output of the former increased by 9kg/667m 2, i.e. the increasing rate was 2.2%. Moreover, the production cost decreased by 27.5-47 yuan/667m 2 and the corresponding income increased by 17.85-49.75 yuan/667m 2 comparing those with the nomal tillage with seedlings throwing.
