东明县胡庄乡采取小麦配方施肥,结果比习惯施肥一般亩增产45～75公斤。这个配方施肥办法如下:一、以地定产,以产定氮肥量。以地块的常年产量为基础,增加10％～15％为定产的产量指标,根据产量指标确定氮肥用量,一般地力水平在施3方有机肥料的基础上,小麦亩产250公斤,施纯氮10公斤左右;亩产300公斤,亩施纯氮12.5公斤左右,在低肥力和高肥力土壤上可增减1.5～2.5公斤氮素。 二、钾肥用量的确定。土壤有效
Huzhuang Township, Dongming County to adopt wheat formula fertilization, the result than the usual fertilization mu yield by 45 to 75 kg. The formula fertilization methods are as follows: First, to local production, to produce nitrogen fertilizer. Based on the perennial output of plots, the yield index of fixed-production increased by 10% -15%. The amount of nitrogen fertilizer was determined according to the yield index. Based on the 3-party organic fertilizers, the general fertility level was 250 kg per mu of wheat, About 10 kg of nitrogen; 300 kg per mu, about 12.5 kg of pure nitrogen Mushu, in low-fertility and high fertility of soil can increase or decrease 1.5 to 2.5 kg of nitrogen. Second, determine the amount of potash. Soil is effective
