Embodiment 2014

[0019] Embodiment In 2014, the drought-resistant cultivation test demonstration of Codonopsis pilosula was carried out in the test field of Longxi County Agricultural Technology Extension Center in Longxi County, and the specific steps are:

[0020] Step 1. Site selection and site preparation: Select the shaded, high-lying, well-drained, deep, loose, neutral or slightly alkaline sandy loam or sandy loam plot in the same area, and rake the soil to level it;

[0021] Step 2 Fertilization: After the previous crops are harvested, immediately remove the stubble and plow and sun-dry. When deep plowing, apply 2500 kg of farmyard manure, 25 kg of urea, 12 kg of diammonium phosphate, and 3 kg of potassium chloride as base fertilizers;

[0022] Step 3 Seedling selection: Seedlings should be transplanted with a seedling age of 1 year, a root length of more than 10 cm, a root diameter of more than 1.0 mm, less mechanical damage, few lateral roots, and a smooth surface. After the seedlings ...

Abstract

The invention belongs to the technical field of drug cultivation, and in particular relates to a drought-resistant cultivation method of codonopsis pilosula. The method is carried out according to thefollowing steps: step 1, land selection and soil preparation; step 2, fertilization; step 3, seedling selection; step 4, transplanting method; step 5, field management, step 6, disease and pest control; step 7, excavation; and step 8, storage. According to the drought-resistant cultivation method of the codonopsis pilosula, temperature can be increased and soil moisture can be maintained, therebyfacilitating yield improvement of medicinal materials; natural resources of light, heat, water, soil, etc. are fully utilized, so that Chinese herbal medicines grow vigorously, and resilience and pest and disease resistance are further enhanced, therefore, occurrence variety and incidence rate of diseases and insect pests are correspondingly reduced, use number and use amount of pesticides are reduced correspondingly, root length and root diameter of the codonopsis pilosula can be significantly improved, thereby increasing a ratio of first-class products, and improving commercial characters of the medicinal materials.

Description

technical field [0001] The invention belongs to the technical field of medicine cultivation, and in particular relates to a drought-resistant cultivation method of Codonopsis pilosula. Background technique [0002] Longxi is the largest planting, processing and seedling base of Chinese herbal medicines in Gansu and even the country. At present, the planting area of ​​Codonopsis pilosula is more than 50,000 mu. Codonopsis pilosula and decoction pieces are exported to all parts of the country, especially in coastal areas. Moreover, a considerable part of Codonopsis pilosula is exported abroad. However, Longxi has been repeatedly affected by droughts in recent years, making the supply of Codonopsis ginseng far less than its demand, which is the fundamental reason why the price of Codonopsis ginseng has remained high. In order to reduce the current situation of imbalance between supply and demand, it is urgent to explore technologies such as cultivation and management to reduc...
