A kind of Gastrodia elata cultivation method

Abstract

A novel gastrodia elata planting and cultivating method comprises the following steps of (1) site selection, (2) soil removal and replacement, (3) preprocessing of seeds, (4) preparation of new materials, (5) cultivation, (6) film mulching, and (7) harvesting. According to the step of cultivation, the cultivation time is the last ten-day period of October to the first ten-day period of December and February to March in the early spring, and gastrodia elata is planted when the air temperature is 0-15 DEG C. According to the step of film mulching, a mulching film with holes is used for mulching soil no matter in autumn and winter or the early spring, the mulching film can be removed at the beginning of April of the next year according to the lunar calendar, the mulching film is put aside, green grass and tree branches are used for covering soil, then a mulching film is used for mulching soil again in the middle ten-day period of August according to the lunar calendar, and the ground temperature can be prolonged by three months; during the film mulching period, the film removing and mulching method is novel, and pest control and water management are identical with traditional methods. According to the step of harvesting, gastrodia elata is harvested at the end of September according to the lunar calendar. The method is reasonable in step, a traditional gastrodia elata cultivating method is creatively modified, yield of gastrodia elata is increased, and benefits are improved.

Description

technical field [0001] The invention relates to a method for planting and cultivating Gastrodia elata. Background technique [0002] Gastrodia elata is a perennial herb distributed in most parts of the country. Its dry tubers, also known as Gastrodia elata, are commonly used and relatively expensive traditional Chinese medicines. They are mostly used clinically for headaches, dizziness, numbness of limbs, convulsions in children, epilepsy, convulsions, and tetanus. Gastrodia elata has always relied on wild resources in the past. After the successful transformation of wild species into domestic species in the 1970s, domestic gastrodia elata became the main source of commodities. [0003] However, the traditional cultivation method has many defects. For example, when inoculating the strains, the fungus branches are used, and the inoculation must begin when the new fungal cords that grow touch the xylem of the fish scale mouth of the new material. In addition, the top of the f...

[0003] However, the traditional cultivation method has many defects. For example, when inoculating the strains, the fungus branches are used, and the inoculation must begin when the new fungal cords that grow touch the xylem of the fish scale mouth of the new material. In addition, the top of the fungal cords is only 0.5-1 The contact surface of millimeters, the contact point can be imagined, which greatly reduces the success rate of inoculation, and increases the probability of bacterial contamination; during cultivation, the normal dry humidity of the soil cannot be guaranteed, resulting in very low yield
