head rice

Generally, small grains have less chalkiness, high head rice rate a nd slight environment effects.

谷粒小粒形可减少垩白, 利于提高整精米率,并减少受环境的影响.

Effects of Temperature on Head Rice Rate

温度对水稻整精米率的影响

The special quality rice breeding and high head rice breeding will be continued.

继续特质米育种和高整精米率育种；

However, the rough out the white rate declined slowly, while the head rice yield declined obviously.

其中糙出白率下降缓慢，整精米率下降明显。

This suggested that appropriate nitrogen treatment improved head rice rate and lowered chalky ratio and chalkiness degree.

适量的氮肥有利于提高整精米率，有降低垩白粒率和垩白度的趋势。

However, influence of drying temperature on head rice yield was significant, and head rice yield sharply reduced with the increase of drying temperature.

稻谷整精米率受干燥温度影响显著，随干燥温度的升高急剧减少。

But China still re-mains in the manual head rice rate inspection stage, so the detection is time-consuming, the test results are not objective and not accurate enough.

但是我国目前仍然停留在人工检测阶段，这样费时费力，同时检测结果也不够客观，不够准确。
