湖南三七林下栽培地选择研究

在湖南省洪江市选择与云南文山三七主产区气候条件相似的猕猴桃林、杉木林、阔叶林、核桃林、葡萄林等5种林地,在林地采集土样,测定其土壤养分含量及pH,并与文山三七种植地的土样测定结果进行对比分析。结果表明:阔叶林地、核桃林地、猕猴桃林地含K量较低,需多施K肥;杉木林地含P量较低,应多施P肥。在以上湖南洪江5种林地的林下种植三七,并合理施肥,采收其肉质根与文山种植的三七进行有效营养成分对比分析,发现两者的产量和品质无明显差异。

The research of selection of cultivation land undergrowth of the Panax notoginseng(Burk.) F.H. Chen in Hunan Province

Wenshan Zhuang and Miao Autonomous Prefecture in Yunnan Province is the main producing area of Panax notoginseng (Burk.) F.H.Chen,we selected five places of kiwifruit forest,Chinese fir forest,broad-leaved forest,walnut forest and grape forest,which were similarity climatic conditions with Wenshan Prefecture in Hongjiang City of Hunan Province for forest land sampling.The soil nutrient content and pH value were measured by collecting soil samples from forestland,and the results were compared with P.notoginseng (Burk.) F.H.Chen plantation of Wenshan Prefecture.The results show that,the content of potassium fertilizer in broad-leaved forest and walnut forest and kiwifruit forest was lower,and need applied more potassium fertilizer.The content of phosphatic fertilizer in Chinese fir woodland is lower,and need applied more phosphatic fertilizer.With the reasonable fertilizer in five kind forest of Hongjiang City in Hunan Province,and compared the effective nutrient composition of harvest fleshy roots of P.notoginseng (Burk.)F.H.Chen,there was no significant difference in its output and quality it in Wenshan Prefecture.
