摘要
土壤钾素亏缺严重限制了我国农业生产的发展,现有钾资源已经不能满足我国农业需要,目前钾资源的开发主要集中在海水和钾矿,而农作物秸杆作为我国的富钾资源,其利用效率和质量都不尽人意,对秸杆的利用大多还停留在田间焚烧、直接还田以及用作牲畜饲料等传统途径,其利用率还不足40%,秸杆的进一步开发应该引起足够的重视。
The loss and lack of potassium in earth has seriously restricted the coutinuous develepment of agriculture in our country which makes it extremely urgent to develop potassium. The present reseach mainly focuses on the seawater and potassimn-ore. The straws are re.ally rich in potassium, but the quantity and quanlity of their use are not satisfactory. So the deep research and development of straws should be paid more attention.
