| 摘 要： | 研究菠萝-甘蔗轮作制对甘蔗生长及土壤生态的影响结果表明,菠萝-甘蔗轮作甘蔗产量和糖度均高于甘蔗-甘蔗连作;与连作田相比轮作田可改善土壤通气性和蓄水能力,加速土壤速效养分的释放,增强土壤酶活性和增加土壤微生物总量;有益的氨化细菌和硝化细菌成倍增加,而无益的厌氧性细菌、反硝化细菌则受抑制。

| Abstract: | The effects of crop rotation of pineapples-sugarcane on sugarcane growth and soil microflora were studied.The results show that both of the sugarcane yield and sucroser content of cane in the crop rotation of pineapple-sugarcane are(higher) than those of the continuous cropping of sugarcane-sugarcane.Compared with other fields,the crop rotation field can improve the capability of aeration and water storage,accelerate the release of the quick effective nutrient,strengthen soil enzyme activity and increase the total quantity of microbe of soil.The beneficial ammonifier and the nitrifying bacteria double increase,while the unbeneficial anaerobic bacteria and denitrifying bacteria are inhibited. |
