Effects of date of sowing and cultivation method on the yield of direct-seeding late rice

In order to select the optimum date of sowing and cultivation method,the effect of different date of sowing and cultivation methods on the yield of late rice was compared in the experiment.The results showed that the yield and economic benefit of direct-seeding late rice with no-tillage were higher seeded on 20 July,the yield was increased by 125.1kg/hm~2 as compared with conventional tillage direct-seeding rice in the same date of sowing and the production value was raised by 175.5 RMB yuan/hm~2,meanwhile,the production cost was reduced by 715.5 RMB yuan/hm~2.
