为考察全水溶螯合态磷酸一铵的增产和促进作物根系生长的效果,分别以谷子和玉米为试验对象开展了田间示范试验和实验室盆栽试验。结果表明:与N-P2O5-K2O分别为15-35-10、19-19-19的氯基掺混肥和磷酸二铵(18-46-0、15-42-0)处理相比,全水溶螯合态磷酸一铵(10-50-0)处理的谷子增产率为2.04%~8.39%,单位养分的谷子产量为17.27 kg/kg;全水溶螯合态磷酸一铵对玉米的株高、茎粗有一定的促进作用,但对根系生长的促进作用不明显。
In order to investigate the effect of water soluble chelated ammonium phosphate on increasing yield and promoting crop root growth, a field demonstration experiment and a laboratory pot experiment are carried out with millet and maize as experimental objects respectively. The results show that compared with the chlorine based bulk blend fertilizers with N-P2O5-K2O (15-35-10 and 19-19-19) and diammonium phosphate (18-46-0 and 15-42-0), the yield increase rate of millet treated with water soluble chelated monoammonium phosphate (10-50-0) is 2.04% -8.39%, and the yield of millet per unit nutrient is 17.27 kg/kg. Water soluble chelated monoammonium phosphate has a certain promoting effect on plant height and stem diameter of corn, but the promoting effect on root growth is not obvious.
