调查了不同施肥处理、水稻不同栽插期稻茎毛眼水蝇危害状况。结果表明,同一品种不同施肥处理稻茎毛眼水蝇危害株率差异不明显,水稻不同栽插期稻茎毛眼水蝇危害株率差异较大,随栽插期推迟危害株率明显增加。并优选出对稻茎毛眼水蝇具有一定抗性的81个水稻品种(系)。
Investigated the different fertilization treatments, rice different planting period of stem and eye Mosquitoes waterflies hazards. The results showed that there was no significant difference in the rate of the harmful strains in the same species and different fertilization treatments. The rates of the harmful strains in the rice stems and stems were significantly different at different planting stages and significantly increased with the delay of planting. 81 rice varieties (lines) with certain resistance to Daphnia magna were selected.
