| 摘 要： | 以山东省寿光蔬菜大棚土壤为供试材料,分析不同年限不同层次的大棚土壤有机质、氮、磷、钾养分含量变化特征。结果表明,土壤有机质、氮、磷、钾养分含量随种植年限的延长总体上呈增加趋势,随土层深度的增加呈下降趋势。方差分析表明,不同种植年限蔬菜大棚土壤有机质、氮、磷、钾养分含量总体上存在显著差异。从土壤养分含量与种植年限的拟合曲线及其求解结果来看,不同土层深度(0~10 cm、10~20 cm、20~40 cm)的土壤有机质、氮、磷、钾养分含量达到最高时的种植年限不同,多数集中在8~11 a。

| Abstract: | In Shouguang of Shandong province,the soil samples in different layers(0-10 cm,10-20 cm,20-40 cm) were collected by means of random sampling for both the different vegetable greenhouses and various planting years.The characteristics of the nutrient contents of organic matter,nitrogen,phosphorus and potassium in the tested soils were analyzed.The results showed that organic matter,total N,alkali-hydrolytic N,total P,available P and available K contents increased with planting ages from one to twelve years an... |
