风沙土农田培肥地力措施研究——以宁夏回族自治区为例

The measures of fostering fertility of aeolia n sand so il in farmland are studied through field experiment. The results show th at all t he measures of fostering fertility can increase the whole and the availa ble nutr ients distinctly, and affect the dumpling structure of soil obviously. The organ ic fertilizer treatment is the best of all, and the capacity of restraini ng wate r of soil increases. A cooperative application of N, P and K can increas e the co ntents of organic matter, available N, available P and available K.
