| 摘 要： | 对冬季多花黑麦草和小黑麦生长速率与气象数据的相关分析表明:测定期间的最高温度与太阳辐射和两种牧草生长速率的相关系数最高,分别为0.96、0.95和0.89、0.79;小黑麦刈割次数的增加会造成生长速率的下降,产量降低。

| Abstract: | The experiment was carried out to study the relation between growth rate of annual ryegrass and triticale and meteorologic factor.The results showed that the relation index of high temperature and solar radiation with both grass's growth rate was the highest,0.96,0.95 and 0.89,0.79 respectively.The growth rate and yield of triticale were decreased with the increase of cutting times. |
