摘要
采用大田试验,以农十师种植面积最大的食葵为研究对象,用3种不同灌溉方式对新疆种植食葵盐碱地的土壤理化性质和微生物特性的影响进行研究。结果表明:渗灌、滴灌和沟灌3个处理对土壤中总盐和pH值有明显的抑制作用,对土壤的速效养分、微生物种群数量、微生物量、碱性磷酸酶、蔗糖酶、蛋白酶、碱性磷酸酶、多酚氧化酶活性有明显的促进作用,对土壤过氧化氢酶活性没有影响。降低土壤的盐分和pH值以沟灌为宜;提高土壤的速效养分、土壤微生物特性以滴灌为宜。
A field experiment is carried out to study the effect of three different irrigation modes on the physical and chemical proper- ties of soil and microbial properties in sunflower saline soil, which is the largest agricultural planting area in the 10th Division of Xin- jiang Production and Construction Corps Agricultural. The results show that the three irrigation modes all have obvious inhibition effect on total salt in soil and pH value and were active and useful to soil nutrients, microorganisms, microbial biomass, enzyme, al- kaline phosphates, sucrose, protease, alkaline phosphates. But the three modes have no effect on soil catalase activity. The furrow irrigation is appropriate to decrease the salt and pH value of soil. The drip irrigation is the best way to increase the soil available nu- trient, soil microbial characteristics.
