摘要
试验研究宁夏回族自治区大田风沙土培肥途径结果表明,各种培肥措施均能明显提高风沙土农田土壤全量养分和速效养分含量,且对土壤团粒结构有较明显影响,其中施有机肥处理影响最大,显著提高土壤蓄水性能。N、P、K配施处理土壤有机质、速效氮、速效磷和速效钾增幅较大。与单施无机肥和单施有机肥相比。
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. Compared wit h fertilizing solely inorganic or organic fertilizer, the cooperative fertilizat ion of inorganic and organic fertilizer can improve the whole and avail able nutrients of soil.
