Cultivation method for one-time seedling input, repeated planting and multiple harvests of Paris polyhoylla var chinens

Abstract

Disclosed is a cultivation method for one-time seedling input, repeated planting and multiple harvests of Paris polyhoylla var chinens. The method includes: cutting a fresh rhizome of collected wild Paris polyhoylla var chinens of five to six years old from two-thirds of distance from the tail end to the top end into two sections, using a 1:300-400 solution of 25% carbendazol wettable powder for subjecting the top end to seed soaking and disinfection, and replanting the top end in a field after wound healing; drying the tail end to produce into commodity Paris polyhoylla var chinens; after emergence of a seedling in the next year, applying 1500kg of decaying high-quality organic fertilizer and 20kg of compound fertilizer per mu in time, then managing according to an artificial cultivation method of the field; after three-year growth, performing harvesting, cutting off and alternate husbandry planting repeatedly, so that one-time seedling input, repeated planting and multiple harvests of the Paris polyhoylla var chinens can be realized. By the method, the problem of shortage restriction of the Paris polyhoylla var chinens seedling can be solved, production cost is lowered greatly, harvest cycle of the Paris polyhoylla var chinens can be shortened, risk that the tail end is decayed and gnawed by pests resulting in reduction of yield is reduced, rhizome growth is fast, yield is high, and average yield is more than 30% higher than yield of conventional cultivation cycles.

Description

Technical field:

[0001] The invention belongs to the technical field of standardized production standard operating procedures (SOP) of traditional Chinese medicinal materials, and is a high-efficiency cultivation method for shortening the production cycle and reducing the production cost of Huazhonglou. Background technique:

[0002] Huazhonglou Paris polyhoylla var.chinens (Franch.) Hara is a variant of Paris polyhoylla var.chinens (Franch.) Hara, Trilliaceae Trilliaceae. It is the authentic medicine source of Zhonglou, and it is a unique and precious Chinese medicinal material in China. The medicinal part is a thick underground rhizome, and its chemical composition is steroidal saponins such as diosgenin, which has expectorant, antibacterial, analgesic, and sedative activities. raw material. At the same time, modern pharmacological studies have shown that Chonglou also has the functions of hemostasis, anti-tumor, and immune regulation. It is widely used in the raw materi...

Embodiment Construction

[0014] In 2006, the wild Huazhonglou was collected, and the seed roots over 5 years old were selected to cut into sections, with two thirds of the tail and one third of the top with buds. The tail end is washed with clear water, and then dried to make commercial eucalyptus or made into decoction pieces for sale. A total of 162.3 kg / mu of commercial eucalyptus is harvested. Soak and disinfect the tops of the buds with 300-400 times liquid of broad-spectrum fungicide 25% carbendazim wettable powder, then spread them out and dry them in a cool place, and plant them in the test field after the wounds heal. The planting specifications are standardized according to the row nest spacing of 40cm×10cm, and the planting density is 16,000 plants / mu. The experiment simulated the wild environment for shading, with a shading degree of 60%. Fertilizers were reapplied in the first year after re-cultivation, and 1500 kg of decomposed high-quality organic fertilizer and 20 kg of compound fertil...
