摘要
结合文献资料,从作物根系的水平分布、垂直分布、硝态氮运移及产量等几个方面,概述了不同灌溉量和灌溉方式对作物的影响,分析了滴灌、渗灌等微灌技术的应用。最后,针对经济林木生产的实际现状,进行了展望:探索一种成本低、简单易操作、便于推广应用的灌溉措施更具有理论和实践意义。
According to the information of literature, this paper summarized the effects of irrigation quantity and irrigation methods on crops from the horizontal distribution and vertical distribution of crops root, nitrate nitrogen migration and production. At the same time, the application of drip irrigation and micro-irrigation technology was analyzed. Finally, the problems lying in current actual situation of economic forest production and the aspects are described. To explore an irrigation measure of low cost, simple, easy to operate, convenient for popularization and application is more theoretical and practical significance.
