The Effect of N2O Emission Mitigation by Growing Soybeans Instead of Other Crops [PDF]
, 2016 农业是重要的温室气体排放源之一，而在农业生产过程中施用氮肥是引起农业温室气体排放的主要原因。因此，如何合理有效的施用氮肥对减少农业温室气体排放、减缓全球气候变化至关重要。鉴于此，对通过合理施用氮肥从而减少温室气体排放的减排措施进行成本效益分析，将有助于我们找到具有经济效益的农业温室气体减排方法。目前，相关减排措施研究主要集中在农田测土配方施肥、改良施肥（缓释肥和长效肥）上。得益于与豆类作物共生的根瘤菌具有的固氮作用，豆类作物相比其他农作物施用更少的氮肥，从而排放更少的氧化亚氮（N2O）。因此 ...

Shuitu Baochi Xuebao, 2002 通过X—射线衍射、室内模拟实验及常规分析研究了吉林省主要耕作土壤中钾的固定与释放。结果表明,土壤对钾的固定与释放与土壤的矿物组成有关,3种土壤的固钾量均随钾加入量的增加而增大,而固钾率则随施钾量的增加而逐渐下降。随钾加入量的增加,固钾量和固钾率均有黑土>白浆土>黑钙土的趋势。土壤释钾量有黑钙土>黑土>白浆土的趋势。相关分析表明,蒙脱石、蛭石为主要的固钾矿物,而伊利石为主要的释钾矿物。
