Getting the five key steps right in Gastrodia elata cultivation can effectively increase yield

To achieve stable and high yields of Gastrodia elata, the first thing is to get the five pre-planting steps right:

First, choose the site. Gastrodia elata cultivation can be adapted to local conditions, whether indoors, in air-raid shelters, semi-basements, or @#@230@#@ sheds. Because Gastrodia elata likes dark, damp, and cool environments, choose places with good ventilation and shade as much as possible, with semi-basements and outdoor trenches giving the best results. You can lay a layer of bricks before use, or increase the thickness of the bottom sand layer to enhance its water permeability.

Second, if the indoor floor is concrete, use high-quality Armillaria mellea fungal material (spawn). The quality of the Armillaria mellea fungal material (spawn) directly affects the yield of Gastrodia elata and is also the key to the success or failure of Gastrodia elata cultivation. When the fungal material (spawn) is of good quality, Armillaria mellea can not only grow onto the Gastrodia elata relatively quickly, but also has a strong ability to absorb and transport nutrients, so the Gastrodia elata can receive an adequate nutrient supply. Fungal material can be cultivated in all four seasons, and you should persist in cultivating new fungal material every year.

Third is to select high-quality Gastrodia elata seed. White-headed tubers and rice tubers have strong division capacity and can both be used as seed to obtain high yields. It is best to select tubers with intact bodies, no damage, no disease spots, fresh, and individual weights of 5-20 grams as seed. For vegetative propagation, be sure to use first-generation or second-generation tubers from sexual reproduction as seed.

Fourth is to sow at the right time. Sowing too early or too late will affect the yield of Gastrodia elata. The specific sowing time should be determined according to local climatic conditions. Generally, in Shandong and areas with a climate similar to Shandong, vegetative cultivation is chosen from November each year to April of the following year, and sexual reproduction should be chosen from late May to July each year.

Fifth is to have a scientific planting method: change long fungal material to short fungal material, with 35-55 cm being suitable. Short fungal material has a high inoculation rate, and Armillaria mellea is easy to propagate; change single-layer cultivation to two-layer cultivation. Two-layer cultivation can prevent both drought and waterlogging. With good management, both layers can yield a harvest, achieving high and stable yields. Change mixed planting of seed tubers to separate planting by size, which helps Gastrodia elata absorb nutrients evenly. In addition, management must be strengthened: prevent freezing, drought, waterlogging, and trampling by people and livestock, and achieve heat preservation, moisture retention, and keeping the soil loose and breathable. Preventing freeze damage to Gastrodia elata in winter is very important. When the ground temperature reaches -5°C, Gastrodia elata will suffer freeze damage. You can use straw curtains, weeds, leaves, various crop straws, etc. to cover it for insulation.
