Gastrodia covering techniques

In the past ten years, the author studied, inspected, experimented, summarized, and promoted Tianma cover cultivation techniques in more than ten provinces and cities in Tianma Production Area, which enabled Tianma to increase production by 20% to 30%. Now introduce the principle and method of coverage increase: 1. Cover the principle of yield increase. Gastrodia elata is a kind of cool and moist plant, which is mainly distributed in undergrowth or shrub forest in nature, and mostly grows in the gentle slope zone of 10°C-30°C. It is both humid and watery during growth; it is not only thermophilic, but also the most suitable temperature is 20°C~25°C, and it is afraid of high temperature, and the temperature exceeds 28°C and the growth pauses. However, artificial cultivation of Gastrodia in order to facilitate and management, often not in the forest, in order to avoid exposure to Tianma cultivation sites or leaching, in Tianma cultivation to cover the deciduous or grass, on the one hand moisture to prevent drought, on the other hand cane block sunlight to prevent high temperatures. In addition, the cover can also suppress or block the growth of weeds and achieve the effect of water retention. Therefore, the cover cultivation technique can create or simulate the environment in which wild gastrodia grows, so that Gastrodia can grow normally under suitable temperature and humidity. 2. Cover cultivation methods. (1) Covers. The first is the leaves. The leaves of broad-leaved trees are the best, and the leaves of pine, cypress, alfalfa, etc. can also be used. The second is grass. The best is hair grass. Straw and corn stalks can also be used. (2) Cover thickness. The thickness of 2 to 5 cm, more than 1,000 meters above sea level can be thinner, and can be thicker than 1000 meters. (3) Coverage method. Coverage is divided into full coverage and half coverage. Full coverage refers to covering both cultivated gastrodiases and gutters. Half coverage is covered only by gastrodiasis cultivation boxes and the gullies do not cover. Coverage is also divided into direct coverage and indirect coverage, direct coverage, covering the immediate coverage of Tianma cultivation box. Indirect coverage refers to the use of arbors on gastrodia cultivation sites. Or the combination of the two, that is, the combination of direct coverage and indirect coverage, the application of this method is obvious in the application of 500 meters above sea level. Wherever conditions permit, it is possible to cover the edges of the plant. When the hemp grows into a vigorous growing season, it is particularly necessary to pay attention to the coverage in the months of 7, 8, and 9. It is particularly important to point out that a drainage ditch must be opened before covering. (4) Management after coverage. If the ditch is cultivated and covered during the cultivation of Gastrodia in November, it can basically be used without management until the middle of May of the following year. However, from mid-May to the end of September, regular inspections and management should be conducted according to actual conditions. The full coverage of the cultivation site is mainly to check the dry humidity, the first half of the cultivation site to check the dry humidity, the second is to regularly remove the ditch weeds. (5) Covered with plastic film. In some places where sexual reproduction is carried out, plastic film is used to keep warm and moisturize during the germination of the seeds of Gastrodia elata. However, in the process of asexual cultivation, if it is covered with plastic film, it must pay great attention to the time and method of covering the plastic film. If the method is not properly covered, it will cause four kinds of unfavorable conditions for gastrodia growth: First, the temperature rises; Is too much stagnant water; Third, the film is not exposed for a longer period of time, not enough water through the rain; Fourth, poor ventilation, while the temperature and humidity are too high, resulting in Gastrodia. Therefore, when the temperature reaches 20°C or more, it does not need to be covered with a film. If covered with a film, the film should be covered with a suitable thickness of earth or fallen leaves depending on the situation.
