    摘要:

    应用大田试验,系统研究了风沙土肥力状况及培肥途径。结果表明 :各种培肥措施均能明显提高土壤全量养分和速效养分含量,而且土壤阳离子代换量及pH值也有所降低。各种培肥措施对土壤团粒结构也有较明显的影响,以有机肥的影响最为明显,而且土壤的蓄水性能显著提高。氮磷钾配合施用土壤有机质、水解氮、速效磷和速效钾提高幅度较大。与单施无机肥和有机肥相比,有机无机配施的培肥效果较好。酿酒葡萄基地生产中,间作可使用地与养地相结合,显著地提高有机质的积累,而且在短期内可以提高土壤耕层有效氮、磷、钾营养元素的含量。

    Abstract:

    The fertility condition and measures of fostering fertility are studied by field-ex periment. The result shows, that all the measures of fostering fertility can increase the whole-nut rients and the quick-acting nutrients obviously, and the exchange capacity of positive-ion and pH of soil decrease. The effect of varied measures to dumpling-structure of soilisex tinct, and the organic fertilizer is the best of all, the capacity of restraining-water increase. Cooperation application of N, P, K can increase the content of organic matter, valid-N, valid-P and valid-K. Cooperation of bio-fertilizer and abio-fertilizer have the better effect compared with singleabio-fertilizer.The intercrossing can be combined by using field with fostering field in production of wine-g rapes, it can increase the accumulation of organic matter extinctly, and increase the content of valid-N, valid-P and valid-K in a shortperiod.
