免耕土壤速效磷含量在整个剖面均低于耕翻土壤 ;0～ 5cm土壤生物量磷含量免耕高于耕翻 ,5～ 15cm免耕低于耕翻 ;施肥和休闲土壤均维持了较高的有效磷和生物量磷水平。种植作物的免耕土壤缓效钾含量与耕翻土壤没有显著差异 ,0～ 5cm速效钾含量呈免耕高于耕翻的趋势 ,休闲的免耕土壤整个剖面缓效钾和速效钾含量都高于耕翻 ;免耕土壤缓效钾的分布无明显的层次性 ,速效钾则相反 ;施肥明显提高土壤速效钾含量 ,但对缓效钾的影响不大。长期免耕没有导致土壤酸化 ;免耕土壤pH与耕翻土壤没有差异
The content of available P in no-till soil was lower than that of tillage soil in the whole section. The content of phosphorus in 0-5 cm soil was higher than tillage in no-tillage, no-tillage in tillage at 5-15 cm and higher in both fertilizers and recreational soils Available phosphorus and biomass phosphorus levels. There was no significant difference between slow-acting potassium content in no-tillage soil and tilled soil. The available potassium content at 0 ~ 5cm was higher than no-tillage tillering trend. The content of slow- In no-tillage soil, the distribution of slow-acting potassium had no obvious gradation and the available potassium was the opposite. Fertilization obviously increased the content of available potassium, but had little effect on slow-acting potassium. Long-term no-tillage did not lead to soil acidification; no-tillage soil pH and tilled soil no difference
