通过田间试验和盆栽试验研究了稻、麦施用硝尿磷肥和硫尿磷肥的肥效。其结果表明在等氮、磷情况下,其效果与磷铵+尿素、过磷酸钙+尿素相近,基本上是等养分等效。施用两种肥料后,对提高土壤有效磷有良好的效果,对土壤pH值影响不大。
The effects of applying nitrate and phosphate fertilizers on rice and wheat were studied through field experiments and pot experiments. The results show that in the case of equal nitrogen and phosphorus, the effect is similar to that of ammonium phosphate + urea, superphosphate + urea, and is basically equivalent to the equivalent nutrients. After applying two kinds of fertilizers, it has a good effect on raising soil available phosphorus and has little effect on soil pH.
