| 摘 要： | 钙镁磷肥的不同用量对花生各生育阶段从土壤中吸收N、P、K营养元素的作用不同.幼苗期,茎叶P/NPK比值表明在0.054～0.064范围较好,茎叶中N、K的含量以1125kg/ha磷肥为好.成熟期,茎叶磷含量随施用量增加而增高.第四纪红土红壤通过花生的种植,土壤有机质,土壤氮素和土壤PH值都有提高,尤其土壤容重明显降低.

| Abstract: | The variant levels of calcium magnesium phosphate affected absorption of N-P-K nutrient with evey peanut bearing state from soil. In the seedling period ,the ratio within 0.054-0.064 was the best P/NPK in stem and leaves. Its N-K content was very well when the level of phosphate is 1 125Kg/ha. In the mature period, its P content raise with the quantity of phosphate raised. When the peanut planting on red soil of 4th surname, the organic matter, N nutrient and pH value increase and the unit weight of soil reduces. |
