摘要
对超级稻甬优12进行了机插和手插栽培对比试验。结果表明,相同播期下,机插与手插的生育期无显著差异;穗粒性状表现为机插有效穗数增、每穗粒数减;分蘖动态有较大差异,表现为机插稻起始分蘖缓慢,分蘖时间长,高峰苗多,群体大,成穗率低;2种栽培方式的产量基本持平,但机插成本和劳动强度降低,经济效益更好,有利于大面积生产。
The effects of different planting methods on super rice Yongyou12 were studied. The results showed that there were no sig-nificant differences in the whole growth period between machine transplanting and artificial transplanting under the same sowing time;the filled grains were decreased while the effective panicles were increased under machine transplanting. The machine transplanting rice had slow tillering, longer tillering period, higher peak seedling, bigger groups and lower spike rate. The yield between different planting methods was almost equal, but the machine transplanting rice had lower cost, higher economic benefits and lower labor inten-sity, and suitable for large-scale rice production.
