免耕水稻直播试验

An experiment of rice direct broadcasting with no-tillage

通过水稻免耕直播、稻草还田免耕直播、常耕直播的对比试验,研究水稻在不同直播栽培条件下对生长、产量和经济效益的影响。结果表明,稻草还田免耕直播和免耕直播处理分别比常耕直播每667m2增产22kg、10kg,节约成本45元,值得在水稻生产上推广应用。

A comparative trial of rice direct broadcasting with no- tillage, direct broadcasting with no - tillage and straw - return - to- field and direct broadcasting with tillage is conducted to study the in- fluence on growth, yield and benefits of different cultivation conditions of rice. The trial result shows that the former two treatments have higher yields of 22 kg/667m^2 and 10 kg/667m^2 than direct broad- casting with tillage, and can save 45 Yuan/667m^2, which means they are worth to apply in rice pro- duction.
