| 摘 要： | 研究了五种氮肥对长沙多索线虫生活力的影响.结果表明,对成虫,ω(CO(NH2)2)大于2.0%,ω(NH4NO3)大于1.0%,ω((NH4)2SO4)大于0.25%,ω(NH4CI)大于0.5%时就有致死作用;而ω(NH4HCO3)的致死作用更强,浓度大于0.1%时线虫死亡.对寄生前期幼虫,四种常用化肥的质量分数大于0.01%时致死或抑制其活力.

Effects of Fertilizers on the Viability of Agamermis Changshaensis |
| |
| Abstract: | The application of fertilizers has a markedly negative effect on the viability of Agamermis changshaensis . Generally, to the adults, when the density of urea is more than 2?%, that of ammonium nitrate 1?%, that of ammonium sulphate 0.25?%, and that of ammounium chloride 0.5?%, they are lethal. Anmonium bicarbonate, is much more strongly toxic when its density is more than 0.1?%. To the pre parasitic larvae, the density of the four kinds of commonly applied fertilizer: NH 4HCO 3, (NH 4) 2SO 4, NH 4NO 3, CO(NH 2) 2 over 0.01?% may result in the death or depression of their juveniles. |
