The Effect And Application Of Different Composting Treatment Of Kitchen Waste

In order to study and apply the kitchen waste better, this article researched the effects of different treatment methods on composting kitchen waste at the treatment effect, and kitchen waste compost applied separately cabbage seedling planting and soil improvement effects,Th e main findings are as follows:(1) adding different ratio of material processes the kitchen waste, The A-4 composting e ffect is more ideal,which kitchen waste and sawdust mixed and added strain under ventilation conditions.Compost temperature rises faster rate than other treatments 1 to 2 days; compost g ermination index reached 80%, respectively, compared with A-1, A-2 and A-3 handle high 90.5%, 25% and 12.7%; compared with the initial value water content decreased about 37%, re ducing the conductivity value of about 50%.(2) the use of earthworms during the processing of kitchen waste, kitchen waste under t he old and new mixed condition B-3 process, the most significant effect. kitchen waste into ve rmicompost manure fastest reduction in volume reached 56.67 percent, respectively, B-1 and1.05-fold and 1.18-fold B-2 treatment. The process average weight and length of each of earth worms were 1.66 times and 1.62 times the initial value.(3) perlite, spent mushroom, and cattle manure can improve the shortcomings of poor v entilation of kitchen waste composting, the effects of three different matrix, perlite> mushroo m compost> cattle manure. the C-2(kitchen waste compost and perlite 3: 1)had the best effec t. the emergence rate reached 91.67% during the processing; height, leaf area index and overa ll seedling were increased by approximately 52%, 177% and 30%.(4) Using kitchen waste compost to improve the soil planting effect, the D-2 and D-3 tr eatment had the best effects which to add 40% and 60% the proportion of kitchen waste comp ost. The kitchen waste can improve soil aeration and soil porosity is maintained at between 55% to 60%; reduce soil bulk density, compared with CK were decreased by 34% and 37%; ad justing the pH of the soil, the pH value remains in acidic and basic environments between 6.0to 7.5; increased soil organic matter, total nitrogen, phosphorus, potassium content effectivel y, promoting the growth of Chinese cabbage. Chinese cabbage yield compared with the contro l CK were increased by 6.79% and 7.9%. Instructions to add about 50% of kitchen waste compost in the soil can not only improve all aspects of the nature of the soil, and can promote the growth of Chinese cabbage.
