围绕我省当前再生稻发展需要，在大田生产中，采用１２个杂优组合对影响再生稻产量的因素进行研究，结果表明：再生穗和实粒数对产量的影响呈显著正相关；通过提高栽培水平，可显著增加再生穗从而达到再生稻增产的目的
Based on the current development needs of ratooning rice in our province, 12 heterosis combinations were used to study the factors affecting the yield of ratooning rice. The results showed that there was a significant positive correlation between the effects of spikelets and grain number on yield. Cultivation level, can significantly increase the regeneration of spike so as to achieve the purpose of ratooning rice yield
