农作物采用什么样的施肥方法,对提高肥料利用率、增加作物产量是个关键问题。如果施肥不当,不但造成浪费,而且会降低肥效减少收益。因此,科学合理的施肥才是提高施肥效益、增加作物产量的有效措施。一、有机肥和化学肥料配合施用。有机肥养分齐全、肥效持久;化肥肥料养分单一,但含量高,见效快。两者配合使用能取长补短,提高肥效。据试验,家畜圈肥与碳铵、过磷酸钙、硫酸钾配合使用,比单施等量化肥增产10% 以上。
Crops using what kind of fertilization methods, to improve fertilizer utilization, increase crop yield is a key issue. Improper fertilization will not only result in waste, but will also reduce manure and reduce returns. Therefore, scientific and reasonable fertilization is to improve fertilization efficiency and increase crop yield effective measures. First, organic fertilizer and chemical fertilizer with the application. Complete organic nutrients, fertilizer lasting effect; fertilizer nutrients a single, but high content, quick. The two can complement each other and improve fertilizer efficiency. According to the experiment, livestock circle fertilizer and ammonium bicarbonate, superphosphate, potassium sulfate with the use of the same amount of fertilizer than the single yield of more than 10%.
