经测定黄粉虫干粪中氮、磷、钾的含量分别为 3.6 6 %、1 .4 0 %和 1 .6 2 % ,碳氮比为9.86 ,优于各类家禽、家畜的粪便 .密封沤制 1 0d的虫粪 ,按 1∶4 0的重量比施入沙土 ,用这种沤肥处理 4 0d ,可使播种的绿豆长成的植株增重 1 7.9% ,这一处理组合的肥效最高The contents of N, P, K and C/N in the dry frass of Tenebrio molitor L. are determined, there are 3.66%, 1.40%, 1.62% and 9.86 respectively. The contents of the three elements are higher than those in the frass of many species of poultry and livestock. The frass are composted for 10 days, then the water logged compost are mixed with sandy soil at ratio of 1∶40, it results the plants of mungbean to gain 17.9% more weight than those of the control plants, this is the best combination of treating the frass to be a fertilizer.
