磷是水稻生长重要元素之一。据我省28个县市普查缺磷(<8ppm)土壤面积占59％,这是影响水稻正常生长因素之一。应用水稻品种耐低磷的特性,筛选耐低磷水稻品种,是提高广大山区低产田产量,具有经济而有效措施。
Phosphorus is one of the important elements of rice growth. According to the survey of 28 counties and cities in our province, phosphorus deficiency (<8ppm) soil area accounted for 59%, which is one of the factors that affect the normal growth of rice. Applying the characteristics of low phosphorus tolerant to rice varieties and screening low-phosphorus tolerant rice varieties is an economical and effective measure to increase the yield of low-yielding fields in mountainous areas.
