磷酸铵是一种兼有氮、磷养分的高浓度水溶性速效性复合肥料,其所含成分大部分能为植物利用,副成分很少,对土壤性质的影响也较小,它比单质化肥具有更多的优越性。今年我们承担了区科技局组织的联合试验任务,目的是测定这种复合肥料比等量单质化肥的增产效益,为今后大面积推广使用提供依据。现将试验结果介绍如下:
Ammonium phosphate is a high-concentration water-soluble fast-acting compound fertilizer containing both nitrogen and phosphorus nutrients. Most of its components can be used by plants with few secondary components and little impact on soil properties. Compared with simple chemical fertilizers Has more advantages. This year we assume the joint test mission organized by the District Science and Technology Bureau, the purpose is to determine the compound fertilizer than the same amount of elemental fertilizer production efficiency, provide a basis for the promotion of large-scale use in the future. Now the test results are as follows:
