摘要: 科尔沁区天然打草场面临着不同程度的退化现象,为了缓解退化、达到更好的土壤改良效果,研究采用施加复合微生物肥料的方法,探究其对土壤理化性质的改变状况。选取腐殖酸、糖蜜发酵和海藻酸3种复合微生物肥料,设置对照、单独施加该3种复合微生物肥料和混合施加等5个处理,分别表示为CK、F、T、H和A。结果表明,施加复合微生物肥料后,土壤的含水量明显增加,土壤容重呈降低的趋势;土壤的有机质含量呈增加的趋势,并且T、H和A处理显著高于CK,尤其是A处理高出CK22.8%。因此,复合微生物肥料对土壤的物理状况和养分平衡起到了很大的促进作用。

Abstract: The natural meadow is facing with various degradations in Horqin. In order to attain better results of soil improvement, the effect of compound bio-fertilizers on soil physical and chemical properties was investigated. The Humic acid, molasses fermentation and alginic acid were selected and the effect of comprehensive the above three compound bio-fertilizers was measured, so there were 5 treatments in this study in addition control, marking CK, F,T, H and A respectively. The results showed that the compound bio-fertilizers increased soil water content and decreased soil bulk density. The soil organism matter was also increased and T,H and A were significantly higher than CK.A was higher than CK by 22.8%. So the compound bio-fertilizers accelerated soil physical condition and nutrient balance.
