摘要
以玛咖为试材,在丽江玛咖种植区海拔2 700、2 850、2 950、3 150m处分别采种植玛咖的土壤和未种植玛咖的土壤,用化学方法测定样品中的速效氮、速效磷、速效钾含量及pH值,研究了丽江市种植玛咖对土壤速效氮、速效磷、速效钾含量及pH值的影响。结果表明:种植玛咖后土壤中的速效氮、速效钾含量降低;种植玛咖后土壤中的速效磷含量高于种植前;部分地区种植玛咖后土壤的酸性增强。
Taking Maca as test material,the effect of the contents of rapidly available nitrogen,phosphorus and potassium and pH value in soil by planting Maca were studied.Took samples from the soil not planting Maca and the soil planting Maca each at the altitude of 2 700 meters,2 850 meters,2 950 meters and 3 150 meters in Lijiang Maca area,and determinated the contents of rapidly available nitrogen,phosphorus and potassium and pH value of each sample.The results showed that after planting Maca,the contents of rapidly available N and K in the soil reduced;the content of rapidly available P in the soil increased and pH value of the soil reduced in some area.
