旱地土壤电超滤-氮和磷中无机与有机组分的分配和解吸溶解动态有很大的不同。电超滤-全氮中的硝态氮和有机氮大致各占一半;电超滤-全磷的绝大部分是无机磷,有机磷的贡献极小。电超滤-吸光量与电超滤-氮有极高的正相关,可以相互换算。二者与冬小麦吸氮量都呈高度相关,远优于土壤全氮和碱解氮等化学指数。电超滤-磷与小麦吸磷量也有很高的相关性,与Mehlieh3-P相同,稍低于Olsen-p,但差异不显著。华北石灰性土壤电超滤-钾值(O-35min)仅为交换性钾值的57%二者的相关性极高,与小麦吸钾量呈中等高度的正相关。从电超滤-养分的解吸动态可以显示它们对植物供应的速率。
Electro-ultrafiltration of upland soil - The dynamics of partition and desorption of inorganic and organic components in nitrogen and phosphorus are quite different. Electro-ultrafiltration - total nitrogen in the nitrate and organic nitrogen roughly half; electrofiltration - the vast majority of total phosphorus is inorganic phosphorus, organic phosphorus contribution is minimal. Electro-Ultrafiltration - absorbance and ultrafiltration - Nitrogen has a very high positive correlation, you can convert each other. Both were highly correlated with nitrogen uptake by winter wheat and much better than chemical indexes such as total nitrogen and available nitrogen. Electroporation - phosphorus and phosphorus uptake of wheat also has a high correlation, the same with Mehlieh3-P, slightly lower than Olsen-p, but the difference was not significant. The correlation between ultrafiltration-potassium (O-35min) of calcareous soil in North China and 57% of exchangeable potassium was extremely high, and it had a moderately positive correlation with potassium uptake in wheat. Electrospray ultrafiltration - the dynamic desorption of nutrients shows their rate of supply to the plant.
