| 摘 要： | 采用田间对比试验、植株分析方法,研究了不同灌水量对精量穴直播水稻培杂泰丰(超级杂交稻)和玉香油占(超级常规稻)二个水稻品种各个生育期干物质重和产量构成因素的影响,并与移栽常规灌溉进行了比较。结果表明,精量穴直播湿润灌溉在相对于精量穴直播常规灌溉节水34.77%的情况下,各产量构成因素没有明显差异;在相对于移栽常规灌溉节水39.16%的情况下,产量构成因素也没有明显差异,达到节水的效果。

| Abstract: | The pairing method and the plant analysis were adopted to study the effect of different water amounts on the yield formation and dry weight of precision hill-direct-seeding rice that Peizataifeng and Yuxiangyouzhan,and compare with transplanting conventional irrigation.The results show that although the water amounts of precision hill-direct-seeding sub irrigation less than that of precision hill-direct-seeding conventional irrigation by 34.77%,and less than that of transplanting conventional irrigation by ... |
