| 摘 要： | 在有效磷含量很低的土壤中,施磷能够显著增加大豆产量,其籽粒产量与施磷量的关系式为y=2287.9 6.5x-0.03x2;并且施磷能够增加大豆蛋白质含量1.0~1.5个百分点,蛋白质产量与施磷量的关系式为y=1015 3.8x-0.017x2;大豆籽粒中蛋白质含量与脂肪含量呈高度负相关,如果以生产脂肪为目标,那么大豆脂肪产量与施磷量的关系式为y=427.4 0.7x-0.0038x2。表4,参4。

| Abstract: | The application of phosphorus could improve soybean yield greatly in soil with low available phosphorus,and a formula concerning the relationship between soybean yield(y) and application rate of phosphorus(x) was y=2287.9 6.5x 0.03x~2.The protein content in soybean seed was increased by 1.0-1.5 percentage with the application of phosphorus,and a formula concerning the relationship between protein yield(y) and application amount of phosphorus(x) was y=1015 3.8X-0.017x~2.The results showed a significantly negative correlation between the protein content and oil content in soybean seed,and a formula concerning the relationship between soybean oil yield and application rate of phosphorus was y=427.4 0.7x-0.0038x~2 provided that the soybean oil yield was a main concern. |
