| 摘 要： | 通过田间试验,对甘肃省黄绵土耕地质量特征及其调控的关键技术进行研究。结果表明,甘肃省黄绵土土壤养分含量低,且因干旱和瘠薄在1999-2001年以后开始下降,土壤质量处于退化状态。以提高自然降水拦蓄率、保蓄率和利用率为治旱突破口,提出集成田间沟垄微集水耕作与地膜、秸秆、沙草二元覆盖等抑蒸技术的治旱耕作关键技术;以提高土壤养分含量、保肥、供肥能力为治薄突破口,提出化肥秋深施、有机无机绿肥配施、秸秆堆腐还田和首选豌豆、扁豆为轮作豆科作物为主的治薄耕作关键技术,通过抗旱作物+治旱技术+治薄技术组配形式,建立黄绵土耕地质量调控关键技术体系。 |

| Abstract: | The characteristics and key regulation techniques have been searched for improve the tilling quality of loessial soil through systematic field tests.The results indicates that the nutrients content of loessial soil are quite lower and continuously falling after 1999-2001 because of serious drought and barren,which implies that the tilling quality of loessial soil is under degeneration.Focusing on drought-and barren-control,research results suggested that the integrated techniques of mountain slope land terr... |
