摘  要：
受农村劳动力减少和水资源日益短缺制约,宁夏引黄灌区插秧稻种植面积逐年萎缩.旱直播是一种水稻轻型栽培方式.试验通过对均行旱条播、均行精量穴播、宽窄行精量穴播3种旱直播栽培条件下富源4号不同播种量进行对比研究,结果表明:播种量在225 kg/hm2以下时有利于增强富源4号抗倒伏能力,提高产量及整精米率,提升品质;采用精量穴播方式种植较旱条播播种量300 kg/hm2时节本增效1 894.8元/hm2以上,其中宽窄行精量穴播播种量225 kg/hm2时节本增效最高,为3 818.8元/hm2.

摘  要：
Under the influences of decrease in rural labor force and shortage of water resources, the rice planting area in Yellow River irrigation area of Ningxia is reducing year by year. The dry direct seeding is a light cultivation mode. The experiment compares different seeding rate of Fuyuan No.4 under the dry direct seeding methods of dry even-strip seeding(sowing in strip), precision even-strip hole seeding(sowing in hole) and wide and narrow row precision hole seeding. The results showed that the seeding rate of below 225 kg/hm2 was useful to strengthen the lodging resistance, improve the yield and head rice rate as well as the quality. The planting of precision whole seeding had obvious effect on decreasing cost and enhancing benefit, which was more than 1 894.8 yuan/hm2 when the seeding quantity of sowing in strip was 300 kg/hm2.The wide and narrow row precision whole seeding of 225 kg/hm2 could gain the maximum benefits with the lowest cost,which is 3 818.8 yuan/hm2.
