查询词典 smut

The most convenient and effective method among the three methods of isolatingUstilaginodea virens was the vibrating method. XBZ medium was the best method toget chlamydospores through screening for the six media. Based on chlamydosporesthrough vibrating cultured in PS liquid on shaking bed at 130r/min under 26℃darkconditions for 7 days, conidia were largely obtained. Occurrence information of rice false smut on paddy at Hengnan in 2006 wasinvestigated.

稻曲病病原菌用3种方法分离，结果比较得出振落法最方便有效；通过对6种培养基的比较筛选，结果表明胁本哲氏培养基能快速的产生大量的厚垣孢子；把厚垣孢子放在PS培养液于水平摇床上26℃黑暗条件下130r／min振荡培养，能在7d产生大量分生孢子。

ConclusionComprehensive consideration suggested that jiarun15ml/hm2、15%xiugu caneffectively control sheath blight and false smut of rice,and commodity features of rice was improved,can substictute difenconazole.

结论经综合考虑，嘉润0.3g/ml乳油15ml/hm2、15%秀谷可湿性粉剂40g/hm2可有效防治水稻纹枯病和稻曲病，有利于提高稻谷的商品性能，可替代30%爱苗乳油。

The results showed that the disease incidence of maize head smut was 31.3% when the soil temperature was 24℃.

试验结果表明，土壤温度为21℃，玉米丝黑穗的发病率最高为31.3%，17℃低温下发病率为10.9%~16.7%，温度在24℃时，发病率为3.7%~4.8%；土壤含水量与病害侵染发病有较明显的关系，土壤湿度为15%时利于孢子萌发与侵染，发病率达为31.1%，湿度10%、20%时发病率仅为3.7%~8.8%，干旱和高湿不利于病菌孢子萌发，湿度是决定发病程度的主导因素。
