| 摘 要： | 针对江西稻田生态环境监测与信息服务的需要，设计了土壤肥力监测方法。并进行了为期1a的试验。试验结果发现，江西稻田土壤呈现出清晰的、规模化的渐进式酸化过程，对水稻品质不利；稻田土壤养分不均衡，有机质含量高，局部有机磷含量偏低，有效钾含量处较低水平，已成为江西水稻高产优质的关键限制因子。另外，试验还发现，根据动态监测结果及时进行土壤肥力干预，均衡科学施肥，可以满足水稻高产优质对养分的需求，有利于提高水稻生产潜力。

| Abstract: | To the ecological environmental monitoring and demand of information service of paddyfield of Jiangxi , designed the soil fertility monitor method, have carried on the la test. The result of the test shows, the paddyfield soil in Jiangxi presents the clear and scale progressive acid course , it is disadvantageous to quality of the paddy. The soil nutrient of paddy field is unbalanced, the organic content is high, the content of some organic phosphorus is on the low side, effective potassium content is on the low-level, become restriction factor of high yield and high quality of Jiangxi paddy already, in addition, the result of the test is also found, according to monitoring the dynamic result and intervening soil fertility in time, balanced science fertilization, can meet the paddy demands of high yield and high quality , is favorable to the productive potentialities of the paddy. |
