叶枯性病害对小麦产量及产量因子的影响

The Effect of Wheat Leaf Blight on Yield Lose and Yield Factors

利用接菌与喷药保护的方法使小麦在不同时期感染叶枯性病害,对发病情况与产量损失的研究表明:病害的发生影响了小麦的产量组成而使小麦减产。并研究了小麦产量组成因子与产量的相互关系,建立了产量损失方程。

By the means of inoculating at different stages and spraying fungicide control disease index to study the relation between disease and yield lose, the result showed that the factors of yield was affected by this disease, meanwhile constructed equations of yield lose.
