研究了在红壤地区垃圾堆肥的肥效及改土效果。田间试验结果表明,施用垃圾堆肥45~90t/hm2,猕猴桃鲜果增产59.2%~332.35%;花生增产16.2%~21.6%。猕猴桃鲜果维生素C含量提高29.87%~35.12%;总糖由43.4g/kg增加到80.48/kg;重金属元素Cu、Cr、Pb、Cd的含量基本上近似对照,与此同时,垃圾堆肥使土壤中对植物根系具毒害作用的交换性Al由12.66mol/kg降为0.32mol/kg.土壤容重由原来的1.3~1.27g/cm3降为1.11~1.10g/m3;田间持水量由15.89%提高到19.04%;总孔隙度由52.6%增加到56.5%;土壤(m/g)微生物的总菌数由0.97×106/g增加到22.5×106/g。─增产极显著。Note:n=11,L.S.D.test,*─Significanceofproductionincrement─Greatsignificanceofproductionincrement表3垃圾肥施用对花生产量的影响(%)Table3Effectofcompostdosageonproductionofpeanut(%)施用垃圾堆肥的猕猴?
The fertilizer effect and soil improvement effect of rubbish compost in red soil area were studied. The results of field trials showed that the application of garbage compost 45 ~ 90t / hm2, kiwifruit yield 59.2% ~ 332.35%; peanut yield 16.2% ~ 21.6%. Kiwifruit fresh fruit vitamin C content increased 29.87% ~ 35.12%; total sugar increased from 43.4g / kg to 80.48 / kg; heavy metal elements Cu, Cr, Pb, Cd content is basically similar to the control, At the same time, the composting of composting reduced the exchangeable Al in the soil, which is toxic to plant roots, from 12.66 mol / kg to 0.32 mol / kg. The soil bulk density decreased from 1.3 ~ 1.27g / cm3 to 1.11 ~ 1.10g / m3; the field water content increased from 15.89% to 19.04%; the total porosity increased from 52.6% To 56.5%. The total number of microorganisms in soil (m / g) increased from 0.97 × 106 / g to 22.5 × 106 / g. ─ Significant increase in production. Note: n = 11, L. S.
