目的:土壤的肥力特征对三七植株养分分布的影响,为三七的种植提供依据。方法:采用统一种植策略。选择种植3年以上的三七种植地,均匀的翻种,取样进行肥力的评价,主要养分都处于适度状态。A组:不改变任何的种植方式,不给予肥料。B组:给予复合肥,重点补充有机质、氮磷钾,提高土壤的养分,保证充足的肥力。C组:同法给予复合肥,但添加强酸性土壤,将酸碱度提升到4.5~5.0之间。然后进行三七的种植,1年为期,成熟后采收进行养分检测。结果:三组对象有机碳、全钾、全铁、全锌含量差异有统计学意义(P<0.05)。结论:土壤肥力是否充足会直接影响三七植株的养分,在开展三七种植时,有必要进行肥力的检测、控制,选择合适的品种,多年轮种需适当休耕。
Objective: The effect of soil fertility on the nutrient distribution of Panax notoginseng plantation provides the basis for the cultivation of Panax notoginseng. Methods: The unified planting strategy. Choose planting more than 3 years of Panax plantation, uniform seed, sampling for fertility evaluation, the main nutrients are in a modest state. Group A: Do not change any planting methods, do not give fertilizer. Group B: given compound fertilizer, focusing on organic matter, nitrogen, phosphorus and potassium, improve soil nutrients, to ensure adequate fertility. Group C: The same method to give compound fertilizer, but add strong acid soil, the pH increased to 4.5 to 5.0. Then the Panax notoginseng plantation, 1-year period, ripe for harvest after nutrient detection. Results: The contents of organic carbon, total potassium, total iron and total zinc in the three groups were significantly different (P <0.05). Conclusion: Whether soil fertility is sufficient will directly affect the nutrient content of Panax notoginseng plant. In the process of Panax notoginseng plantation, it is necessary to detect and control fertility, select suitable varieties and properly fallow for many years.
