近年来,随着农业生产的迅猛发展,农作物产量大幅度提高,长期集约种植加大了对地力的消耗,加之施肥不平衡,使我国土壤缺钾日趋严重,已成为制约我国农业发展的因素之一。而我国又是钾肥资源贫乏的国家,如何解决这个突出的矛盾,是摆在我们面前的重要课题。 湖北省农科院原子能应用研究所涂书新博士和郭智芬研究员主持的“富钾植物对土壤矿物钾吸收利用的机理研究”,通过应用同位素示踪技术对籽粒苋的根际特征试
In recent years, with the rapid development of agricultural production, the output of crops has been greatly increased, and the long-term intensive planting has increased the consumption of soil fertility. In addition, the uneven application of fertilizers has made our country’s soil potassium deficiency increasingly serious and has become a factor that restricts the development of agriculture in our country one. However, our country is also a country with poor potash resources. How to solve this outstanding contradiction is an important issue before us.
