进行中粳稻分蘖穗率对产量构成和稻米品质影响试验，结果表明：中粳多穗型品种西光和大穗型品种农林２８６分蘖穗率分别为２５．７％～９３．２％和８．２％～９０．３％，其分蘖穗率（Ｘ）与稻谷产量（Ｙ）间呈显著正相关；分蘖穗率达７０％以上显著增产，其结实率和千粒重无显著差异，亩有效穗数虽略有减少，但每穗粒数显著增加，分蘖穗率（ｘ）与亩颖花量（ｙ）呈极显著正相关。在本试验条件下，分蘖穗率高低对稻谷糙米率、精米率、整精米率等加工品质和垩白粒率、长宽比等外观品质无显著影响。
The results showed that the spike-tillering rates of 286 seedlings in Xiguang and Big Spike cultivars with mid-japonica multi-spike cultivars were 25.7% -93.2% and 8.2% respectively % To 90.3%, and the tillering spike rate (X) was significantly and positively correlated with the grain yield (Y). The tillering spike rate was up to 70%, and the seed setting rate and grain weight per spike had no significant difference. Slightly decreased, but the grain number per spike increased significantly. The tillering spike rate (x) had a significant positive correlation with the spikelet yield (y). Under the experimental conditions, the tillering spike rate had no significant effect on the quality of brown rice, milled rice and milled rice, the quality of chalky rice, the aspect ratio and other aspect quality.
