不同水稻种植年限对土壤酶活性的影响研究

Effects of Different Continuous Cropping Years on Soil Enzyme Activities of Rice

以乌鲁木齐米东区水稻地为研究对象,对不同连作年限对水稻地土壤酶活性的影响进行了研究。结果表明,随着连作年限的增加,过氧化氢酶活性呈先降后升的趋势;脲酶活性呈上升的趋势,但上升的幅度不显著;蔗糖酶的活性呈现先下降后上升的趋势。

The effects of continuous cropping of rice on soil enzyme activity were explored, taking Urumqi M eastern rice as the object of study.The results showed that, with increasing years of continuous cropping, catalade activity first decreased and then rised; urease activity was in an upward trend, but rising no-significantly; the invertase activity showed first decreased and then in- creased trend.
