Abstract/Summary:
Rural biogas development can not only exploit energy resources, and promote the benign circulation of agriculture. By the end of2012, the city household biogas has reached138000, directly benefiting the population reached460000, year increase revenue and reduce expenditure207000000yuan. In order to widen the scope of the comprehensive utilization of "three.", and solve the pollution of chemical fertilizer pesticide residues in vegetable production, biogas residue, biogas slurry test application effect in Welsh onion seed soaking, production and greenhouse squash production and application were studied, and the analysis of the biogas slurry on onion yield and quality, the basic results are as follows:I test confirmed:Biogas Slurry Soaking can promote the germination and seedling leaves Allium species growth, Biogas Slurry Soaking seedling rate increased to90%,4%higher than the control.I] Welsh Onion cultivation in the late of biogas residue, biogas slurry and different proportion of fertilizer (Fertilization3) test, test design of7kinds of treatment, results show that:the topdressing biogas residue and biogas slurry could improve the Welsh Onion yield, yield increased by13.9%-19.7%, the ratio of4:1(water:biogas slurry) yield the highest, up to37575kg/hm2, increased by19.7%, and the Welsh Onion rust almost No.III different biogas slurry ratio of Welsh Onion had significant effects on the quality of. The content of total sugar, biogas slurry treatment products, the content of Vc increased crude protein content in. Among them:the total sugar in5:1slurry ratio is highest, is1.18times that of the control; Vc to5:1of biogas slurry is relatively high, is1.15times that of the control; crude protein in4:1of biogas slurry with relatively high, increased by1.85%than ckIV In squash in greenhouse production in winter, topdressing different ratio of biogas slurry, plant stem stout, dark green leaf color, the biogas slurry ratio of4:1(water:biogas slurry) treatment yield up to149587kg/hm2.To sum up:the use of biogas slurry had a good effect in Welsh onion seed soaking, production, seed soaking treatment can improve the seedling rate90%, reduce the rust, increase the yield of19.7%. and can improve the quality, method of application to the ratio of5:1is appropriate. In squash in greenhouse production in the application also has effect on increasing yield, the yield increased14.5%, application methods suitable for4:1.
