硝酸盐在草坪生态系统中的淋溶是变化无常的.影响硝酸盐淋溶的因素包括土壤类型,灌溉、降水、温度、氮肥的种类、用量及使用季节。着重研究了不同的草坪和气候区域中氮、磷化合物的转化。研究内容以氮的活动为主。 试验还没有完成,但目前获得的数据可以进行一些比较,其中包括所有项目中每年硝酸盐淋溶量的大体比较。不同气候区、不同土壤类型中硝酸盐的淋溶量比较、以及氮的
The leaching of nitrate from turf ecosystems is volatile, and the factors affecting nitrate leaching include soil type, irrigation, precipitation, temperature, type of nitrogen fertilizer, amount used and season of use. Emphasis was placed on the conversion of nitrogen and phosphorus compounds in different lawns and climatic zones. The main content of the study is nitrogen activity. The trial has not yet been completed, but some data are available for comparison, including a general comparison of annual nitrate leaching in all projects. In different climatic zones, different types of soil nitrate leaching compared to the amount of nitrogen
