摘要:
利用三种不同长度的土柱,模拟研究了有机肥对土壤剖面中土壤硝态氮淋失的影响.结果表明,有机肥对KNO3氮肥中NO3--N的淋失有一定抑制作用;施加有机肥可提高土壤碱解态氮含量;有机肥本身亦可产生NO3--N淋失.
Abstract:
The simulated test was conducted by means of three kinds of soil column of 60 cm,100 cm and 150 cm length.The results were as follows: The organic manure could reduce leaching of NO3--N from KNO3 addition and increase the level of soil hydrolable nitrogen.The organic manure itself could produce leaching of NO3--N in soil column.
