播种量与施氮量对直播水稻苏香粳3号产量的影响

摘要

通过裂区试验研究了播种量和施氮量对直播水稻苏香粳3号产量的影响,研究结果表明:在本试验条件下,播种量为90 kg/hm2,施氮量为225 kg/hm2时直播水稻苏香粳3号的产量最高,达到6697.50 kg/hm2.%The effects of seeding rate and nitrogen application rate on the yield of directly - sown rice variety Suxiangjing No. 3 were studied through split - plot experiment, the results showed that: under the experimental conditions, the directly - sown Suxiangjing No. 3 had the highest yield (6697.50 kg/hm2) al the seeding rate of 90 kg/hm2 and the nitrogen application rate of 225 kg/ hm2
