不同包衣剂对水稻播后上水不同播种密度产量的影响

Effects of Different Coating Materials and Sowing Density on Yields under Irrigation after Sowing

以宁粳28号为试验水稻品种,选择锐胜和亮盾2种包衣剂,研究4种不同播种密度下水稻产量。结果表明,同一播种密度,锐胜+亮盾包衣剂水稻产量高于亮盾包衣剂;播种密度17.5 kg/667 m^(2)、锐胜+亮盾包衣剂水稻产量最高,适宜大面积推广。

Taking Ningjing NO.28 as testing rice variety,Ruisheng and Liangdun were selected as the coating materials to study the effects of four kinds of sowing densities on rice yields.The results showed that the rice yield was the highest under the treatment of Ruisheng and Liangdun coating materials.The sowing density was 17.5 kg/667 m^(2).The deeding method can be widespread.
