不同类型土壤对大豆磷肥利用率影响的研究

试验选用黑土、草甸土、白浆土等类型土壤进行盆栽试验，研究了大豆在不同类型土壤中常规施肥的磷肥利用率；通过采用氨磷钾最佳比例及用量与叶面喷施液体肥料相结合的方法，使大豆磷肥利用率与常规化肥用量相比在黑土中提高6.25个百分点；在草甸土中提高5.12个百分点；在白浆土中提高5.86个百分点。大豆产量与常规化肥用量相比，分别在黑土、草甸土、白浆土中增产6.73%、9.56%、7.69%。

STUDY THE RATE OF SOYBEAN ABSORBING THE PHOPHORUS IN DIFFERENT SOIL TYPES

The test is planting the soybean that use pot-culture method on the black soil ,meadow soil and lessive soil.Studing the utilization value of the phosphate fertilizer about soybean in the different soil types.Using the proportion and the value of the N,P,K and the liquid fertilizer on the crop leaf ,the utilization value of the phosphate fertilizer wite soybean whose was best treatmete was raised 6.25% than conventional treatment's in the black soil,raised 5.86% in the lessive soil and raised 5.12% in the meadow soil.Compared the best treatment,the yield of soybean was raised in the black soil,meadow soil and lessive soil.The nember separet is 6.73%,9.56%and 7.69%.
