摘要
为探索全程施用沼肥对玉米产量及土壤养分的影响,进行了田间试验。结果表明:施用沼肥能保证玉米增产,提高土壤肥力,改善土壤结构,增产增肥效果显著[3][4][5]。以沼肥1500kg为基肥,苗期、拔节期、大喇叭口期分别根部施用沼肥500Kg+尿素5Kg 1次为最佳。
In order to explore the effect of the biogas fertilizer on maizeyield and soil fertility, carries on the field test.The results show that:the application of biogas fertilizer can guarantee that the corn yield,improve soil fertility, improve soil structure, increase fertility effect.Using biogas fertilizer 1500 kgas base fertilizer,seedling,jointing, booting 500Kg+root of biogas fertilizer urea 5Kg1 times for the best.
