从2016年开始,重庆承担“援孟加拉国水稻技术合作项目”。2016年,援孟加拉国专家组在雨季设立了水稻机插秧与孟式栽培(孟加拉国常规种植方法)的对比试验及示范。结果表明:机插秧每盘125 g播种量的缺窝率低,单位面积产量最高,建议实际生产中采用每盘125 g播种量;机插秧最高苗少于孟式栽培(对照);机插秧667 m2有效穗比孟式栽培少,但成穗率比孟式栽培高6.3~11.9百分点;机插秧每穗平均实粒数比孟式栽培多。
From 2016 onwards, Chongqing undertakes the “aid to Bangladesh rice technology cooperation project”. In 2016, the Panel of Experts for Bangladesh assisted in setting up a comparative experiment and demonstration of the rice transplanting and the cultivation of Meng-style (the conventional method of planting in Bangladesh) in the rainy season. The results showed that the planting density of 125 g per plant was low and the yield per unit area was the highest. It is suggested that 125 g per seed per plant should be used in actual production. m2 effective spike less than the Meng-style cultivation, but the spike rate was higher than the Meng-type cultivation 6.3 ~ 11.9 percentage points; machine seedlings per spike average grain number more than the Meng-style cultivation.
