摘要
选取两个水稻新品种松粳20和松粳21,对其进行群体构建研究。结果表明:产量与株距呈显著负相关关系,与基本苗数相关不显著;不同株距处理对长宽比无影响,对出糙率、整精米率影响不明显;随着株距的增大,垩白度和垩白粒率有降低趋势,透明度有增加趋势;每个品种的个处理间整精米都是2苗>5苗、8苗,两个品种的垩白度和垩白米率是2苗处理最低。
We select two new rice Songjing 20 and Songjing 21 to carry out research on the construction of 21 groups.The results show that： There was a significant negative correlation between yield and plant spacing, no significant correlation with the number of basic seedlings; Different spacing treatment on the aspect ratio of no effect is not obvious on the roughness, the milled rice rate influence;With the increase of plant spacing, chalkiness and chalky grain rate decreased,increased transparency; Processing each variety between milled rice is 2 more than 5 seedlings seedlings, 8 seedlings,two varieties of chalkiness and chalky rice seedling lowest rate is 2.
