    摘要:

    圍繞旱地農(nóng)業(yè)生產(chǎn)中的水肥資源高效利用展開討論，主要介紹了以3種典型化學(xué)調(diào)控制劑（土壤改良劑PAM,、土壤保水劑SAP和蒸騰抑制劑FA）為代表的化學(xué)調(diào)控技術(shù)在旱地農(nóng)業(yè)水肥資源利用方面的調(diào)控機(jī)制和應(yīng)用方法,，重點(diǎn)對化學(xué)調(diào)控技術(shù)在旱地農(nóng)業(yè)生產(chǎn)中的增強(qiáng)水肥保蓄、提高坡地水土保持,、改善作物水肥利用性能及提升作物品質(zhì)和產(chǎn)量4個重要環(huán)節(jié)上的應(yīng)用研究進(jìn)行了綜述,，最后提出未來化學(xué)調(diào)控技術(shù)在旱地農(nóng)業(yè)中應(yīng)用的重點(diǎn)研究方向,。

    Abstract:

    The issue on the theme of efficient utilization of water and fertilizer in dry-land agriculture was discussed. The mechanism of action of three typical chemical agents (soil conditioner—PAM, water retaining agent—SAP, antitranspirant—FA) in regulation of water and fertilizer and its application methods were introduced. Research of chemical regulating technology on four important parts were emphatically reviewed (enhancement of the accumulation of water and fertilizer, improvement of the soil and water conservation, improvement of the utilization of crop to water and fertilizer, increasing of the crop yield and quality) in dry-land agriculture production. Finally, the future important research directions were proposed.
