本研究着重探讨了水稻超稀植栽培技术中插秧形式对分蘖生产力的影响。设置了30cm×26.4cm、40cm×20cm和(50+30)cm×20cm三种不同插秧形式的处理。试验结果表明:在同等密度条件下,30cm×26.4cm形式有利于增加有效穗数,40cm×20cm形式的单垄宽行有利于增加1穗粒数,(50+30)cm×20cm形式的双垄宽行有利于增加千粒重。因此,水稻超稀植栽培的插秧形式要考虑土壤肥力,即窄行稀植(如30cm×26.4cm)适于低肥力土壤,以便增加穗数;;宽行稀植适于肥力较高的土壤或增肥田,以便增加穗粒数或提高千粒重。
This study focused on the effects of transplanting seedlings on tillering productivity in ultra-thin rice cultivation techniques. The treatments of 30cm × 26.4cm, 40cm × 20cm and (50 + 30) cm × 20cm were set up. The results showed that under the same density condition, the 30cm × 26.4cm form was beneficial to increase the effective panicle number. The single ridge width of 40cm × 20cm was beneficial to increase the number of grains per spike. The double ridge (50 + 30) cm × 20cm Wide line is conducive to increase 1000 grain weight. Therefore, the transplanting rice cultivation methods should consider the soil fertility, that is narrow row thinning (such as 30cm × 26.4cm) suitable for low-fertility soils to increase the number of spikes; wide row thinning suitable for higher fertility Soil or fertilizer field, in order to increase grain number per spike or increase 1000-grain weight.
