Increase the output of Gastrodia elata

In order to achieve stable and high yield, Gastrodia elata must first set the first five hurdles for good planting:

One is to choose the venue. Gastrodia elata can be planted according to local conditions, such as indoor, air-raid shelter, semi-basement, @ # @ 230 shelter, etc. Because Gastrodia elata likes dark, moist and cool environment, we should try to choose places with good ventilation and shade, among which semi-basement and field gutter are the best. It can be reused by laying a layer of brick, or the thickness of the bottom sand can be thickened to enhance its water permeability.

Second, if the indoor is a cement floor, high-quality Armillaria mellea material (species) is used. The quality of Armillaria mellea material (species) is directly related to the yield of Gastrodia elata, and it is also the key to the success or failure of Gastrodia elata cultivation. Armillaria mellea can not only grow quickly on Gastrodia elata, but also has strong ability to absorb and transport nutrients, and Gastrodia elata can get sufficient nutrient supply. Fungus can be cultivated all the year round, and new fungus should be cultivated every year.

The third is to select high-quality Gastrodia elata. White-headed hemp and rice hemp have strong meristematic ability, and high yield can be obtained when planting seeds. It is better to choose flax with intact body, no damage, no disease spot, fresh and individual at 5 ~ 20g. Asexual cultivation must choose the first or second generation of sexual reproduction.

The fourth is to sow seeds 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 the local climatic conditions. Generally in Shandong and Shandong similar climate areas, asexual cultivation is selected from November to April of the following year. Sexual reproduction should be selected from late May to July every year.

The fifth is to have a scientific planting method, change the length of fungus material into short fungus material, 35-55 cm is suitable. The inoculation rate of short fungus is high, Armillaria mellea is easy to reproduce, and the monolayer cultivation is changed to two-layer cultivation. Two-layer cultivation can not only prevent drought, but also prevent waterlogging, good management, two layers are bumper harvest, can obtain high and stable yield. Change the mixed planting of Gastrodia elata to separate planting size, which is beneficial to the uniform absorption of nutrients by Gastrodia elata. In addition, it is necessary to strengthen management, prevent frost, drought, waterlogging, and trampling by human and livestock, keep warm, moisturize, and keep the soil loose and ventilated. It is very important to prevent the freezing injury of Gastrodia elata in winter. Gastrodia elata will suffer frost damage when the ground temperature reaches-5 ℃. It can be covered with grass curtain, weeds, leaves, all kinds of crop straw and so on.
