为在翻耕条件下合理施用紫云英,保障农业的可持续性发展,定位试验研究了15000kg· hm~(-2)、22500kg· hm~(-2)、30000kg· hm~(-2)紫云英还田和22500kg· hm~(-2)紫云英还田减施化肥(施肥时扣除紫云英中氮、磷、钾)及紫云英不还田5个处理对烟田土壤微生物数量、微生物活度、酶的影响。结果表明:烟草生育期内,不同处理好气性细菌数量呈前期均迅速上升、中期均稍有上升,但后期各有升降的趋势; 烟草生长早期,紫云英还田减施化肥能增加好气性细菌数量。放线菌数量烟草生育前期略有下降,中期有所回升,后期又缓慢下降; 烟草生长早期,紫云英还田能增加放线菌数量; 整个烟草生育期,紫云英还田减施化肥可...

The organic fertilizer A. sinicus has a strong nitrogen fixing ability. The effect of returning A. sinicus to tobacco cultivated soils on microbial population, activity and enzyme activity was investigated with the aim of enhancing sustainable agro-development. The treatments were set at 15 000 kg·hm^-2, 22 500 kg·hm^-2, 30 000 kg·hm^-2 A. sinicus, as well as NPK-reduced 22 500 kg·hm^-2 A. sinicus, in which NPK amount in A. sinicus was reduced from fertilizer, with non A. sinicus treatment as the control. The results show that aerobic bacte...
