畜禽粪便复混肥研制及其肥效初探

Manufacture and Apply Efficiency of Organic-mineral Mixing Composts Derived from Livestock Manure

利用猪粪、鸡粪及其垫料进行了高温堆肥化及有机-无机复混肥的研制和应用效果的初步试验。结果表明,堆肥化温度升至55℃以上保持了一周时间,达到了无害化要求;经过100d的堆制,堆肥基本腐熟。腐熟堆肥与化肥配制的有机-无机复混肥可明显促进玉米株高和生物量的增加,与对照相比,施用复混肥的玉米株高和生物量在中肥力土壤上分别增加了11.4%和71.8%,在低肥力土壤上分别增加了8.9%和43.2%;复混肥对水稻的生长促进作用非常明显,与对照相比,施用复混肥水稻的株高、分蘖数和生物量在中肥力土壤上分别增加了15.4%、58.5%和78.3%,在低肥力土壤上分别增加了29.4%、104.5%和247%。即在低肥力土壤上的促进作用高于中肥力土壤。

The compost test in an automatic compost device using livestock manure(pig manure, chicken manure)and agriculture waste(rice husk )was conducted.The results showed that the compost temperature increased to 55℃ and kept for one week,which satisfied the need of innoxiousness.After 100 days,the compost was matured.The organic-mineral mixing composts was manufactured by using this matured composts and some mineral fertilizers.The effects of this mixed composts and others fertilizers on corn and rice growth were studied through pot experiment.The results indicated that this mixed composts could increasethe corn and rice stem height and biomass obviously.Applied with this mixed composts,the stem height and biomass of corn were increased by 11.4% and 71.8% in the middle fertility soil,and by 8.9% and 43.2% in the low fertility soil respectively compared with the control;and the stem height,and biomass of rice were increased by 15.4%,58.5% and 78.3% in the middle fertility soil,and by 29.4%,104.5% and 247% in the low fertility soil respectively compared with the control.
