| 摘 要： | 对云南不同野生稻植株中氮、磷、钾、铁、镁、硼的含量及其相应生长土壤中矿质元素含量进行分析.所涉及的稻作材料和土壤中各种矿质元素的含量差异较大.根据植株材料中矿质元素含量与相应生长土壤中可利用的元素含量的比值,初步探讨了云南不同野生稻对不同营养元素的吸收能力.

| Abstract: | The contents of nitrogen, phosphate, potassium, iron, magnesium and boron in wild rice plants and their corresponding soil were analyzed. Results showed that there were obvious differences in contents between plant and their soil. According to the ratios of con- tents of mineral elements in plants to soil, the absorption efficiency of different Ytmnan wild rice to different nutrient element were preliminarily compared. |
