【摘要】 干旱区棉花完全依赖于灌溉,因而只有合理的水肥配合,“以水促肥,以肥调水”,才能达到水分和养分的高效利用。本文从养分对棉花水分利用效率的影响、水分对棉花吸收养分的影响、水肥耦合对棉花叶面积指数和散射光透过率的影响等方面综述了棉花水肥耦合效应研究的进展,讨论提出今后棉花水肥耦合的研究应重视土壤养分运移机制、根系提水作用、棉花不同生育阶段需水需肥规律、养分生物有效性等方面工作。更多还原

【Abstract】 In arid land, cotton must be irrigated. It is necessary to manage water and fertilizer integrated in order to use them efficiently. So it is important to research water-fertilizer coupling in arid region. This paper reviewed it from nutrients effects on water use efficiency of cotton, water influences to nutrient use efficiency of cotton, influencing of water-fertilizer coupling to LAI and TD. Furthermore, it discussed and proposed to study more about mechanism of soil nutrients movement, increasing of upper soil water content by cotton roots, law of water and fertilizer requirement of cotton in different growth stage, and biological availability of nutrients etc.更多还原
