土壤水分与肥料是制约农业生产的两大因素,如何通过有效的措施,更好地协调水肥关系,以达到合理经济地利用水分和养分是旱地农业研究的目的.本文对近几年一部分水肥耦合研究的内容进行了简单的分类,并分析了各类的研究状况,对研究的发展趋势进行了展望.综合评述了水肥耦合的机理性研究和应用研究,预测发展“平衡施肥”和节水的生态农业,实现旱地农业的可持续发展是未来农业的发展方向.
The water and fertilizers are me two greatest factors that limit agriculture produce, the purpose of the agriculture research of dry land is how to take the valid measures and co-ordinate the relationship of water and fertilizers more betterly in order to use water and fertilizers more reasonable and economic. The research of couple effect of water and fertility was classed in this paper, and each kind of research condition was analyzed, and the prospect of development trend of research was viewed. This paper summarizes the mechanism studies of couple effect of water and fertility . It point out that the trend of agricultural development is developing ecological agriculture.
