不同水稻品种对负泥虫的抗性鉴定及其对产量的影响

Sdudy of Rice Varieties Resistant to Oulema oryzae

以寒地稻田优势害虫水稻负泥虫(Oulema oryzae)为研究对象,选取黑龙江省主栽水稻品种结合田间调查和室内嗅觉选择等方法进行抗虫性试验。结果表明,供试的6个水稻品种中抗虫品种为绥粳4号,感虫品种为垦鉴5号、稻花香2号,中感品种为05345,中抗品种为丰园2号、空育131。种植抗虫水稻品种,可以实现对水稻负泥虫可持续控制。

Oulema oryzae was the dominant spider in cold paddy field as the research objective. The main cultivated rice va- rieties in Heilongjiang region were screened according as the resistance to O. oryzae. Combined investigation in field with ex- periments in greenhouse,the results showed that variety Kenjian5 （KJ5） and Daohuaxiang 2 （DHX2） were highly susceptible variety. Variety 05345 was medium susceptible variety. Fengyuan2 （FY2）and Kongyul31 （KY131） were medium resistant variety. Suijing 4（SJ4） was highly resistant variety. Planting insect-resistant rice varieties could realize sustainable control of O. oryzae.
