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.
