磷酸二铵是当前广大农民喜欢使用的优质高浓度的氮磷复合肥。生产实践证明:这种复合肥适用于各种农作物和各种土壤,特别是适用于需磷较多的作物和缺磷土壤。可作种肥、基肥和追肥,具有显著的增产效果。但是,在施用磷酸二铵时应注意以下五个问题,才能提高磷酸二铵的利用率。 1.严格控制施用量这种复合肥所含的氮、磷比例大体为1:2.5一4.4,尽管肥效高,增产显著,但也不能无限制地过多施用,如果用量大,不仅浪费了肥料,增加了开支,而且还会造成烧种、烧苗。一般在施足农家肥作底
Diammonium phosphate is currently used by farmers like high-quality high-concentration nitrogen and phosphorus fertilizer. Production practice has proved that: This fertilizer is suitable for a variety of crops and all kinds of soil, especially for more phosphorus needs of crops and phosphorus-deficient soil. Can be used as seed fertilizer, base fertilizer and dressing, with a significant increase in yield. However, in the application of diammonium phosphate should pay attention to the following five questions, in order to improve the utilization of diammonium phosphate. 1. Strict control of the amount of application of this compound fertilizer contains nitrogen and phosphorus ratio of roughly 1: 2.5 to 4.4, despite the fertilizer efficiency, yield significant, but it can not be unlimited too much application, if the amount of large, not only a waste of fertilizer , Increased spending, but also cause burning seedlings, seedlings. In general, full application of fertilizer at the end of the farm
