采用正交Ｌ８（４×２８）试验方法，研究不同抗、感杂优组合地优６４和威优６４混合播种栽培的控瘟性，结果表明对抑制穗颈瘟病指数下降４６．３２％～４７．１７％。大田示范控叶瘟、穗瘟效果分别达３３．３２％和３７．６６％，增产１３．９８％。
The orthogonal experiment L8 (4 × 28) was used to study the control of mixed blast resistance of hybrid 64 and Weiyou 64 cultivars with different resistant and susceptible combinations. The results showed that the inhibition index of panicle blast decreased 46.32% ~ 47 .17%. Field demonstration leaf control blast, panicle blast effect reached 33.32% and 37.66%, an increase of 13.98%.
