摘要
本文通过主因子分析方法,对青海东部设施蔬菜种植区的土壤质量状况进行了综合分析评价。结果表明:青海东部设施蔬菜种植区38个土壤耕层样点,21.05%(8个)的土壤处于优等级水平,60.53%(23个)的土壤处于良等级水平,18.42%(7个)的土壤处于中等级水平,土壤有机质和速效钾是限制该地区土壤质量的主要因子,所以在今后的设施蔬菜生产中应增施有机肥和钾肥,减少磷肥的施用。
Based on principal factor analysis,the soil quality of greenhouse vegetable planting area in eastern Qinghai Province was analyzed and evaluated comprehensively.The results showed that 21.05%(8 pieces)of the 38 topsoil samples was in the excellent grade level,60.53%(23 pieces)of the soil was in the good grade level,and 18.42%(7 pieces)of the soil was in the medium grade level.Soil organic matter and available potassium were the main factors limiting the soil quality in this area.It shows that greenhouse vegetable growing should increase the application of organic fertilizer and potassium fertilizer,and reduce the application of phosphate fertilizer in the future.
