【摘要】 以森林土,种植西洋参1、2、3、4年的农田土,种植西洋参4年后休地1年的老参地土以及老参地轮作大豆、角瓜1年后的土样为试材,研究西洋参不同栽培模式下对土壤全效氮、磷、钾含量的影响。结果表明,农田土栽培的西洋参全效氮、磷、钾含量均在种植第3年时达到最高,分别高于对照森林土18.74%、22.46%和3.53%。种植西洋参4年后的老参地分别轮作大豆、角瓜1年后,可有效增加土壤中全效氮、磷、钾的含量。更多还原

【Abstract】 Forest soil, farmland soil after planting Panax quinquefolium 1,2,3,4 year, old soil after planting Panax quinquefolium 4 years, old Panax quinquefolium soil-soybean, zucchini rotation were used as test material, the study aimed to investigate the effect of different cultivation patterns of Panax quinquefolium on the contents of nitrogen, phosphorus and potassium in soil. The result showed that the content of farmland soil total nitrogen, total phosphorus, potassium which planted Panax quinquefolium reached the highest in third year, higher than CK-forest soil 18.74 percent, 22.46 percent and 3.53 percent respectively. The old Panax quinquefolium soil-soybean, zucchini rotation 1 year later can effectively improve the content of the content of nitrogen, phosphorus and potassium in soil.更多还原
