小麦分层施基肥,是根据不同的土壤,选择有机肥、氮肥、磷肥或钾肥,在小麦播种前施入不同土层中作基肥的一种新技术。在一般土壤中,将有机肥和磷肥作全层肥,施入25厘米的耕层中;氮肥(碳铵)的60％作中层肥,浅翻施入10～12厘米处,20％拌干细土用作覆盖小麦种,余下的20％到春天时看苗追肥。碳铵全部用量一般为每亩60公斤。若土壤中缺钾,也可将钾肥用量的60％～70％与有机肥、磷肥一起作全层肥,其余30％～40％作苗肥早施。小麦分层施基肥应注意的问题 1.土壤肥力高、有 Wheat layered base fertilizer, is based on different soil, choose organic fertilizer, nitrogen fertilizer, phosphate fertilizer or potassium fertilizer, applied to different soil layers before sowing as a new technology base fertilizer. In general soil, the organic fertilizer and phosphate fertilizer for full-thickness fertilizer, applied to 25 cm of plow layer; nitrogen fertilizer (ammonium bicarbonate) of 60% for the middle layer of fertilizer, shallow turn into 10 to 12 cm, 20% mixed dry Fine soil used to cover the wheat species, the remaining 20% ​​to see the spring when the top dressing fertilizer. The total amount of ammonium bicarbonate is generally 60 kilograms per mu. If the soil potassium, but also the amount of 60% to 70% of potash fertilizer and organic fertilizer, phosphate fertilizer together for the whole layer, and the remaining 30% ~ 40% as early as seedling fertilizer. Wheat layered base fertilizer should pay attention to the problem 1. Soil fertility, there
