In searching for the optimum method for amelioration of solid organic waste by remedying black soil and tackling rainfall changes, effects of water conditions and solid organic wastes are studied on particulate organic carbon (POC) structure by ¹³C‐NMR spectroscopic analysis in a 3‐year split‐plot experiment. Experimental plots are under natural rainfall, water deficit, and excess water with single chemical fertilizer, cow manure, chicken manure, crop, or plant residue treatments. The results reveal that solid organic wastes have the potential to improve POC stability. Under natural rainfall conditions, the degressive order by the POC stability is plant residue, crop residue, cow manure, and then chicken manure; under water deficit, it is plant residue, crop residue, chicken manure, and then cow manure; under excess water conditions, it is plant residue, cow manure, chicken manure, and then crop residue. The interchange between aromatic carbon and alkyl or alkoxy carbon gives a remarkable reflection of the effect of water on POC structure. The plant residue increases the aromatic carbon at rates of 4.6, 6.4, and 9.3% under natural rainfall, water deficit, and excess water conditions, respectively. Studying the three water conditions, it could be shown that under a water deficit or excess water condition, both chicken manure and crop residues are unfavorable to POC stability; cow manure is conducive to POC stability only under excess water condition. Leaves, therefore, serve as the optimum amelioration material.

不同水分条件下固体有机废物对土壤颗粒有机碳结构的影响

在寻找通过补救黑土和应对降雨变化来改善固体有机废物的最佳方法时，研究了水条件和固体有机废物对颗粒状有机碳结构的影响[ ^13]。在3年的分裂图实验中进行C-NMR光谱分析。实验地块处于自然降雨，缺水和单化学肥料，牛粪，鸡粪，农作物或植物残渣处理过量水的条件下。结果表明，固体有机废物具有改善POC稳定性的潜力。在自然降雨条件下，POC稳定性降低的顺序是植物残渣，农作物残渣，牛粪肥，然后是鸡粪。在缺水情况下，是植物残渣，农作物残渣，鸡粪，然后是牛粪。在过量的水条件下，它是植物残渣，牛粪，鸡粪，然后是农作物残渣。芳族碳与烷基或烷氧基碳之间的互换显着反映了水对POC结构的影响。在自然降雨，缺水和水分过多的情况下，植物残渣分别以4.6％，6.4％和9.3％的速率增加芳族碳。研究这三种水的条件，可以证明在缺水或过量水的条件下，鸡粪和农作物残留物都不利于POC的稳定性。牛粪仅在过量水分条件下才有助于POC稳定性。因此，叶子是最佳的改良材料。
