| 摘 要： | 土壤培养和盆栽试验结果表明：与无机磷肥相比,有机结合态磷肥能够大幅提高土壤微生物数量和土壤磷酸酶含量；有机结合态磷原产物与磷矿粉配合的有机结合态磷肥对提高土壤微生物量的效果最好,比无机磷肥提高23倍,对提高土壤磷酸酶含量的效果也最好,比无机磷肥提高约6倍；有机结合态磷原产物与缓释氮配合的效果次之,但与前者差异幅度不大.有机结合态磷肥具有降低土壤pH的效果,对pH较高的石灰性土壤效果良好,在pH低的红壤上应选用磷矿粉与有机结合态磷原产物复合的肥料效果较好.

| Abstract: | The results from soil culture and pot culture experiments show that when compared with inorganic phosphatic fertilizers, organic combined phosphatic fertilizers can greatly increase the quantity of soil microbes and the content of soil phosphatase ; the original organic combined phosphatic product is mixed with ground phosphate rock to become organic combined phosphatic fertilizers, which give the best results of increasing the soil microbe quantuity, 23 times higher than that of inorganic phosphatic fertilizers, and also the soil phosphatase content, 6 times higher than that of inorganic phosphatic fertilizers; next to the results of original organic combined product mixed with slow-release nitrogenous fertilizers, but not much different from the former. Organic combined phosphatic fertilizers have the effect of lowering the soil pH value, good for calcareous soil with a high pH value, and for red earth with a low pH value it is better to choose the compounds of ground phosphate rock mixed with organic combined phosphatic fertilizers, to give good results. |
