摘要:
随着江苏省农业生产的发展,土壤钾素越来越入不敷出,土镶钾素含量下降,平均每年下降2.3mg/kg。本文从土壤钾素平衡入手,分析了江苏土壤钾素收支情况,针对钾肥资源十分紧缺的现状,提出解决缺钾的途径。
Abstract:
As agriculture develops in Jiangsu Province, potassium deficiency in soil is caused by soil potassium decrease at the rate of 2. 3 mp/kg per year. It is envisaged, in light of potassium balance in soil, total yields of grain and cotton for successive years in the province and application rate of both potash and compound fertithers, that the amount of inorganic/chemical potash fertilizers needed by Jiangsu for the future years should be increased. Considering the desperate shortage of K, several wars for the improvement of soil K were suggested.
