Suitable cultivation time for Tianma: Gastrodia elata cultivation is generally from late October of that year to April of the following year. Sowing before soil freezing from late October to early December is winter planting, sowing after soil thawing from March to April in spring is spring planting, and sowing time in high altitude mountainous areas can be postponed to May. Second, the choice of Tianma planting site: Cultivation site can be selected in front of the house, wilderness slope, orchard woodland and other land fields, especially with strong permeability of sandy loam for the best. The soil pH is 5-6. Third, Tianma planting ridge requirements: The flat land can be used as a ridge according to the width of 80 cm, the depth of 10 cm and the length of any limit; the wilderness slope can be built into a ladder-type horizontal ridge according to the slope terrain, and the distance between the ridge and the ridge is about 1 meter. The trees and weeds on the edge of the ridge shall be preserved as much as possible for shade, ridge prevention or ridge collapse. Orchard woodland is built according to topography, and drainage ditches are excavated around it. 4. Gastrodia elata seed cultivation method: arranging the bacterial material section tubes with the diameter of 5-8 cm and the length of 30 cm at the bottom of the bed according to the square shape of the word "field", and positioning and discharging 15 tubes of bacterial material per square meter. Then spread the bacterial branches about 2 cm in diameter and 10 cm in length in the open space of the bacterial material box, and spread about 2 kg of bacterial branches in each square space with the bacterial material level. Then Tianma seeds are sown at both ends and both sides of each tube of fungus material, and 66 seeds are sown at fixed points of about 500g per square meter. Finally, wet sandy loam or humus soil with PH value of 5-6 is used to fill the gaps between the fungi and the fungi branches until the fungi are covered to a depth of 2 cm, and the dry branches and weeds with a thickness of 10-20 cm are covered on the surface of the whole ridge soil, and the drainage ditch is dredged. 5. Daily management points of Gastrodia elata: 1. Management of planting temperature: The suitable temperature for Gastrodia elata production is 13-25 degrees (10 cm below the soil surface). In this temperature range, the higher the better. Temperature-controlling is an important work in the management of wild Tianma imitation cultivation. In winter, it is necessary to freeze. In areas below 1000 meters above sea level, 10-20 cm thick branches and leaves and weeds can be covered after planting; in areas above 1000 meters, the cover can be thickened to 30 cm. Summer and autumn to prevent high temperature and drought, in addition to the use of shade to prevent high temperature, but also can use water to reduce soil temperature. Water replenishment is carried out after sunset and temperature drop. 2, planting water management: winter to the next spring (before Qingming) soil temperature control in 10%-20%. 4-6 The soil moisture is increased by about 60% per month. 6-8 Gastrodia elata enters the peak season growth period, nutrition accumulation reaches the peak, at this time should keep water and temperature, preserve moisture and drain, and carry out comprehensive management. In September, the nutrient accumulation of Gastrodia elata enters the later stage and reaches the physiological mature stage. At this time, the soil humidity of the bed should be controlled below 40%. The soil temperature has dropped to 10℃ in late October. Gastrodia elata enters the dormant period, and the soil can be dug up. Each square meter can dig fresh gastrodia elata 7 kilograms or so. VI. Control methods of gastrodia elata diseases and insect pests: The main pests harming the growth of Gastrodia elata are clams, grubs, white ants and so on.
