Detailed Explanation of Key Points of Electromagnetic Field Cultivation Techniques for Gastrodia elata

In the practice of cultivating Gastrodia elata, it has been found that in cultivation areas stimulated by natural lightning and thunder, the Gastrodia elata tubers are large, of good quality, and high in yield. Based on this phenomenon, people conducted asexual propagation cultivation experiments on Gastrodia elata by simulating natural electromagnetic fields, and achieved success, obtaining high benefits for several consecutive years with an average yield of more than 10 kg of Gastrodia elata per sq m, with some reaching as high as more than 20 kg.

Cultivation time of Gastrodia elata and selection of Gastrodia elata seeds

Cultivation is generally carried out when Gastrodia elata enters the dormant period. That is, autumn, winter, and spring are all suitable for cultivation. However, due to different regional climates, the cultivation time of Gastrodia elata also varies. In Shandong, Shanxi, Henan, Hebei and other provinces, asexual propagation cultivation of Gastrodia elata is generally carried out in March, with harvesting and transplanting of Gastrodia elata carried out simultaneously. Sexual propagation cultivation of Gastrodia elata is generally best carried out in May and June.

Selection of seeds for asexual propagation of Gastrodia elata. The degeneration of Gastrodia elata seeds is particularly serious. In recent years, for asexual propagation cultivation of Gastrodia elata in Shandong and other provinces, the seeds generally selected are excellent 0-1 generation Gastrodia elata seeds from hybridization of red-stem and green-stem Gastrodia elata, and Gastrodia elata seeds of generation 3 or above are all eliminated and not used.

Scope of Electromagnetic Field Cultivation of Gastrodia elata

With electromagnetic field cultivation of Gastrodia elata, it can be used in mountainous areas, plains, barren hills, barren beaches, idle urban sheds, basements, air-raid shelters, in front of and behind rural houses, cellars, cave dwellings, orchards, and all other idle places that do not grow crops or vegetation. As long as electromagnetic field techniques are properly applied and temperature and humidity are well controlled, high quality and high yield of Gastrodia elata can be obtained.

Preparation of raw materials

Generally, cultivating 1 sq m of Gastrodia elata requires 500 g of 0-1 generation Gastrodia elata seeds, 4 bottles of Armillaria mellea cultivation spawn with a net weight of 750 g per bottle, 18-20 fresh hardwood broadleaf tree logs with a diameter of 3-10 cm and a length of 60 cm (weighing about 30 kg), 0.25 m3 of clean medium-coarse river sand, 10 m of electromagnetic wire. A grower cultivating within 100 sq m needs to prepare one small magnetizer (generally the investment is about 100 yuan per sq m, and the net income is about 200-300 yuan).

Cultivation of Gastrodia elata

The cultivation time of Gastrodia elata varies by region. In temperate regions, spring cultivation of Gastrodia elata is generally carried out in March. During cultivation, first spread river sand 5 cm thick on the ground (if it is a cement floor, spread river sand 10 cm thick). The humidity of the river sand should be 40%. After the river sand is spread, leveled, and compacted, dig the bottled Armillaria mellea solid cultivation spawn out of the bottles and break it into small pieces, place 1 strand along the position where the logs will be placed, and place 1 log on top of the 1 strand of Armillaria mellea and compact it. At intervals of 5 cm, use the same method to spread Armillaria mellea and place logs. On top of the logs, at 5 cm from both ends of the logs, place 1 electromagnetic wire along each side of the cultivation bed. The electromagnetic wire should connect to the second Gastrodia elata cultivation layer. Then cover the Armillaria mellea with a little medium-coarse river sand, and place 1 Gastrodia elata seed at intervals of 4-5 cm along both sides of the logs (special attention must be paid not to put Gastrodia elata seeds together with Armillaria mellea spawn, to prevent the Gastrodia elata seeds from rotting). Also place 1 Gastrodia elata seed at each end of the logs. First sprinkle a small amount of sand to fill the gaps between the logs, then also sprinkle 1 strand of Armillaria mellea on top of the logs to cover the logs. Then cover with river sand 5 cm thick. After completing the first layer of cultivation, use the same method to cultivate the second layer, also connecting the electromagnetic wire, and finally cover with 8-10 cm of medium-coarse river sand. On top of the river sand, place 2 cm thick leaves or rice straw to help preserve warmth and moisture. Leave the two ends of the electromagnetic wire exposed as power connection terminals for later use.

Daily management of Gastrodia elata

Twenty days after cultivation of Gastrodia elata, water thoroughly once, and thereafter water once every 15 days. When the temperature rises above 27 degC, stop watering and carry out cooling management. Every 9 days, connect the magnetizer to the electromagnetic wire, turn on the power switch, and adjust to 1.5 volts, 2 volts, 3 volts, 6 volts, 12 volts, gradually increasing the electromagnetic field of the electromagnetic wave from small to large in stages according to the development status of Gastrodia elata and Armillaria mellea, to stimulate the rapid growth of Armillaria mellea and Gastrodia elata. According to measurements, using electromagnetic field cultivation of Gastrodia elata can rapidly activate and accelerate the fission and expansion growth of the molecular structures of Armillaria mellea and Gastrodia elata, thereby greatly improving the quality and yield of Gastrodia elata. If temperature and humidity are controlled appropriately, using electromagnetic field cultivation of Gastrodia elata, some can reach more than 20 kg per sq m, making it one of the effective ways to achieve high quality and high yield of Gastrodia elata at present.
