不同施肥处理对连作大豆土壤无机磷组分及作物产量的影响 |
| 5. | The investigations turned out that with the successive planting of crops the mainly available nutrients accumulated yearly under normal fertilization in the upland fields form yellow soil area , especially the content of p increased obviously
在该地区目前的施肥水平下，旱地长期种植作物后土壤主要有效养分的含量都出现不同程度的增加，其中土壤磷的积累最明显。 |
