通过对１１个籽粒苋品种的引种观测、综合评价，选定Ｃｒ０７２为较理想的富钾绿肥；模拟试验结果表明生物钾肥的钾素释放与等钾量的化肥有相同的趋势和特点；盆栽试验探明了籽粒苋对土壤缓效钾和矿物钾具有较强的活化、吸收能力。富钾绿肥的开发利用对缓解我国钾肥资源不足将发挥重要作用。
Through the introduction observation and comprehensive evaluation of eleven amaranth varieties, Cr072 was selected as the ideal potassium-rich green manure. The results of simulation experiments showed that the potassium release of bio-potash fertilizer had the same trend and characteristics with the equivalent potassium fertilizer. The pot experiment It was found that amaranth had strong activation and absorption capacity on soil slow-acting potassium and mineral potassium. The development and utilization of potassium-rich green manure will play an important role in alleviating the shortage of potash resources in our country.
