水稻剪株率与产量损失率关系的研究

Study on the Relationship between the Rate of Rice Plant-cut and the Rate of Output Lost

模拟鼠害,在水稻受害高峰期进行剪株率与产量损失率关系的研究。结果表明两者成直线正相关,相关系数0.995—0.999,差异极显著。结实率随剪株率的增加而提高,但千粒重相对稳定。

A simulant test was carried on in the high peak period of rice injury. The relationship between the rate of rice plant-cut and the rate of rice output lost was studied The result showed that both looked like s atraight positive relativity. The relative coefficient was 0.995-0.999. an obvious difference can be seen. The rate of fruiting of rice incresed with the rate of riceplant-cut increasing, but the thou sand grain weight was stable.
