旱地玉米秋施肥技术研究

Study on Fertilizing Technology in Drought Corn Field

旱地玉米秋施肥可有效地蓄积丰富的秋水供春用,改善土壤墒情,为玉米种子的萌动生长创造一个良好的环境。秋施肥后,玉米苗全、苗壮,单位穗数、穗粒数和穗粒重增加。秋施肥较传统施肥水分利用率提高0.5%～3.8%,增加玉米产量432.0～1003.5kg/hm2,增加纯收入348.6～935.3元/hm2。

Fertilizing in the drought corn field in autumn can accumulate lots of water for spring use, and improve the soil moisture, which can provide a better environment for corn seeds to germinate and burgeon. The corn seedlings are strong and full when they were fertilized in the autumn. Meanwhile, the amount of ears and grains will increase, and the weight of 1 000-grain will increasee either. The moisture utilizing rate will be increased 0.5% - 3.8%. The yield of corn will be increased 432.0 - 1 003.5 kg per hectare, and the net income will be increased 348.6 - 935.3 yuan.
