Effects And Estimate Of Biogas Slurry Apply In Economical Cost Production Of Peach

Biogas slurry is high quality organic leftover which was after anaerobic ferment for firedamp with crop culm and dejecta. It has abundant alimentation element as N,PandK, and exist as quick result nutrient, so it has all-around nutrient and high using percent which is all-around quick result compound fertilizer. Integrate using investigation and estimate Guiyang biogas slurry on peach is theory gist for scientify use biogas slurry in Guiyang and important approach for produce high efficient,low consume and no-harm fruits, accelerate increase agriculture yield and income, improve production condition, construct ecotypic agriculture realize agriculture sustainable development. In this study effects and estimate of biogas slurry apply in peach economical cost production of peach cultivars "Yanhong " were investigated.1. The effects of different biogas slurry concentration(original concentration, accede to double water, accede to 4 times water and accede to 8 times water) and CK(compound fertilizer) on the yield and quality of "Yanhong" peach were investigated. The results showed that yield of each peach tree and average fuilt weight has no difference on biogas slurry concentration treatments but improved with CK. Sense quality of "Yanhong " peach at original concentration and accede to double water treatments significantly well than accede to 4 times water and accede to 8 times water treatments. Biogas slurry can improve quality of "Yanhong " peach, the soluble solid substance, Vitamin C, soluble sugar content increased with biogas slurry concentration increase. also sense quality improved. biogas slurry cound decreased the bulk density of soil, it also cound increased soil porosity and improve the hold water and fertilizer capability of soil. The leaf was very green and thick, the tree has good disease resistance and grow well on biogas slurry treatments. biogas slurry cound decrease nitrate content, it cound save cost and improve efficiency.2. The effects of different kinds of fertilizer (biogas slurry, farmhouse fertilizer, and compound fertilizer)on the yield and quality of "Yanhong " peach were investigated. The results showed that yield of each peach tree and average fuilt weight has no difference on each treatment. But sense quality of "Yanhong " peach at biogas slurry treatment significantly well than other treatments. By cost accounting of different kings of fertilizer, the cost of compound fertilizer is 3.5 times than biogas slurry.The work force of farmhouse fertilizer is 6 times than biogas slurry.
