为指导玉米科学施肥,在博乐市进行玉米“3417”肥料效应试验,结果表明:试验田土壤供氮量为211.5 kg/hm2,供磷量为100.8kg/hm2,供钾量为253.8 kg/hm2,属中肥力水平;该试验田最佳施肥方法为基肥、追肥结合,基肥施有机肥、磷肥、钾肥、锌肥的全部,尿素总量的20%,65%、15%的氮肥分别作追肥进行使用;在当地最优施肥量基础上,施锌肥22.5 kg/hm2,玉米产量为13 333.3 kg/hm2;施锰肥30 kg/hm2,产量为13 500.0 kg/hm2,施硫肥30 kg/hm2,产量为12 666.7 kg/hm2,增产效果较好。
In order to guide the scientific fertilization of maize, the “3417” fertilizer effect experiment on corn was conducted in Bole. The results showed that the soil nitrogen supply was 211.5 kg / hm2, the yield of phosphorus was 100.8 kg / hm2 and the amount of potassium was 253.8 kg / hm2, belong to the level of fertility; The best fertilization method for the experimental field for the base fertilizer, top dressing combination, basal fertilizer application of organic fertilizer, phosphate fertilizer, potassium fertilizer, zinc fertilizer all, urea 20%, 65%, 15% Topdressing was carried out. Based on the optimal fertilization rate in the region, zinc fertilizer was 22.5 kg / hm2 and corn production was 13,333.3 kg / hm2. Manganese fertilizer was applied at 30 kg / hm2 and the yield was 13 500.0 kg / hm2. kg / hm2, yield 12 666.7 kg / hm2, yield better.
