摘要
采用田间试验将沼渣与复合肥和有机肥施用效果对比,结果表明不同用量的沼渣对植物生长均有一定的促进作用,特别是最大叶宽和长势。沼渣能显著提高产量。沼渣处理1、2、3与空白处理相比,产量分别提高704、1 057和1 481kg/hm2;复合肥对小青菜的生长性状和产量促进作用最大,其中产量提高4 756kg/hm2。沼渣、有机肥和复合肥均在一定程度上提高土壤中各组分的含量。本研究为沼渣农田施用提供了理论依据。
Field experiments were performed to investigate the effects of biogas fertilizer, compound fertilizer and organic fertilizer. The results showed that biogas fertilizers with different doses improved the growth of green cabbage to a certain degree, especially on the maximum blade width and living situation. Biogas fertilizer increased the yield of green cabbage. Compared with the control, the first three groups treated with different dose of biogas fertilizer increased the yield by 2. 11, 3. 17 and 4. 44 kg/hm2, respectively,which are equal to 704, 1 057 and 1 481 kg/hm2, respectively. The compound fertilizer had most improving effects on the growth characters and yield of green cabbage, with a promotion yield of 4 756 kg/hm2. Biogas fertilizer, compound fertilizer, and organic fertilizer increased the levels of soil composition. The investigation provides a useful reference for the application of biogas fertilizer in farmland.
