Problems solved by technology

However, Coptis chinensis is mostly wild, and the yield is extremely low, only about 4kg / mu, which cannot meet the market demand. Therefore, through artificial measures, strengthening field management and fertilization technology has become an important way to increase the yield of Coptis chinensis in artificial cultivation.

specific Embodiment 1

[0030] Specific Example 1: At the end of April 2007, 100 mu of Coptis chinensis seedlings were planted in a forest at an altitude of 2600-2700 m near Zhiziluo Village, Fugong County, Nujiang Prefecture, Yunnan Province. Before planting, remove small shrubs, weeds and unrotted litter in the forest with a slope of 10-30°, open the box according to the slope direction, loosen the soil, and level off the box. The length of the box is 5m and the width is 1.5m; Coptis chinensis is planted in a pond, the depth of the pond is about 2-5cm, and the distance between plants and rows is 20cm×30cm. Three months after planting, apply 2 kg of urea and 5 kg of superphosphate per mu. In April of the second year, the Yunhuanglian plant will branch out from the mother plant and gradually form new plants. During this period, it needs a large amount of nutrient supply. Apply 2kg of urea and 5kg of superphosphate mixed fertilizer per mu per month, and apply zinc sulfate heptahydrate (ZnSO4·7H2O) on...

specific Embodiment 2

[0031] Specific Example 2: At the end of April 2007, 20 mu of Coptis chinensis seedlings were planted in a forest at an altitude of 2400 m near Zhiziluo Village, Fugong County, Nujiang Prefecture, Yunnan Province. The slope of the planting plot is 25-30°. Before planting, the small shrubs, weeds and unrotted litter are removed under the forest, and the box is opened according to the slope direction and the soil is loosened and leveled. The box is 5m long and 1m wide; Coptis chinensis is planted by digging a pond, the depth of the pond is about 2-5cm, and the distance between plants and rows is 30cm×30cm. Three months after planting, 3 kg of urea and 5 kg of superphosphate were applied per mu. In April of the second year, the Yunhuanglian plant will branch out from the mother plant and gradually form new plants. During this period, a large amount of nutrients are needed. Apply 3kg of urea and 5kg of superphosphate mixed fertilizer per mu per month, and apply zinc sulfate h...

Abstract

The invention relates to the technical field of plant cultivation, in particular to a coptis teeta cultivation and fertilizing method. In the coptis teeta cultivation and fertilizing method, soil preparation, field planting, fertilizing and the like are adopted, nitrogenous fertilizer, phosphatic fertilizer and micro element fertilizer are applied in the growth period of coptis teeta, and plant growth and rhizome alkaloid generation are facilitated. The method has the advantages of being capable of obviously improving the yield and achieving great economic benefits. Local advantageous forestland resources can be fully utilized to develop the forest undergrowth industry, and obvious ecological benefits and economic benefits can be embodied on the premise that forest plants are less damaged. Soil nutrition conditions are changed through manual fertilizing, and sufficient nutrients are provided for growth of the coptis teeta. Microelements are additionally applied to promote synthesis of alkaloid, a high biological yield is guaranteed, a high alkaloid content is acquired at the same time, and quality of the coptis teeta is improved; meanwhile, the method is adopted based on field forest undergrowth cultivation, a growth environment the same as that of field coptis teeta is achieved, and product geoherbalism is guaranteed.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a method for cultivating and fertilizing Coptis chinensis. Background technique [0002] Coptis teeta wall., also known as Coptis teeta wall., is a perennial herb of the genus Coptis in the family Ranunculaceae, with yellow rhizomes, dense internodes and many fibrous roots. Mainly distributed in Gongshan, Fugong, Lushui, Tengchong and other places in northwestern Yunnan, and also in southeastern Tibet and northeastern India; often grows in broad-leaved forests at an altitude of 2000-2700 meters. Among the many coptises in China, Yunhuanglian has the highest content of alkaloids, especially berberine, and its quality is good. In "Medical Records of Honest Officials", Yunhuanglian is listed as the best, and the use of this variety is strongly advocated. However, Coptis chinensis is mostly wild, and the yield is extremely low, only about 4kg / mu, which cannot meet the mark...
