采用中熟晚粳品种南粳46进行稻鸭共作搁田效果试验,结果表明:与不搁田相比,搁田处理株型协调,稻株抗倒性增强,穗粒数显著提高为141.70粒,比不搁田处理多5.45粒;结实率、千粒重比不搁田分别提高1.65个百分点和0.23g;产量比不搁田增加377.25kg/hm2,增幅为5.4%;经济效益提高了2 608.1元/hm2,增幅5.84%。
The results showed that compared with no repose field, the compatibility of plant type and the lodging resistance of rice plants increased significantly with the mid-ripening japonica rice variety Nanjing 46, and the grain number per spike was significantly increased to 141.70 The grain yield was increased by 5.45 compared with no treatment. The seed setting rate and grain weight per kilogram increased by 1.65 percentage points and 0.23g respectively. The output increased by 377.25kg / hm2 compared with no increase by 5.47%. The economic benefit increased by 2 608.1 Yuan / hm2, an increase of 5.84%.
