高海拔地区水稻精量穴直播技术试验初报

A Preliminary Study on Precision Rice Direct Seeding in High Altitude Area

为了进一步提高农业的精简化栽培,减少农户对人力、物力的投入,通过使用直播机高海拔地区进行水稻精确穴直播技术的研究。结果表明:直播处理下,有效穗数为20.77万/667m2,穗粒数为127.39粒/穗,结实率达82.93%,千粒重为26g,实际产量达到555.7kg/667m2,比当地平均产量增产26.01%,效益提高265.92元/667m2。因此推广水稻精量穴直播技术对于减少农民投入、减少劳动力输出、增加产量有重要的推广意义。

For further improve the simplify cultivation on agriculture, and reduce the input of human power and material re- sources, and study by precision rice direct seeding with direct sowing machine. The result showed that with the direct--seeder, the number of effective panicle was 207. 7 × 108/667m2, grain number per--panicle was 127. 39, the 1000--grain weight was 26g, seed--setting rate was 82. 93%; reached a yield of 555. 7kg/667m2, yield increase 26. 01% compared with the local pro- duction level, and increase the benefit with 265. 92Yuan/667m2. Therefore extension precision rice direct seeding have impor- tant significance in reduce the input of human power and material resources, and increase output.
