Therefore, the first step in planting gastrodia is to cultivate a certain number of high-quality honey ring fungus materials, and the second step is to purchase gastrodia seeds. And in time with honey ring fungus planting.

Environment: The suitable temperature for the growth of gastrodia is 10-30, the optimal temperature is 20-25, the relative humidity of the air is about 80%, the soil moisture content is 50%-55%, and the pH value is 5-6, which is the acidic ecological environment.

The harvest of gastrodia is all done by hand. First use a hoe to remove the surface soil, the top buds of arrow hemp grow upward, often grow out of the top of the fungus, the top bud is most likely to be damaged when shoveling the soil, should be carefully shoveled and digged, when approaching the fungus stick, that is, use a pickaxe to pry up the fungus to pick up the gastrodia. Care should also be taken when crowbars, sometimes the gastrodia squeezed between the sticks will be broken, and after prying the sticks, check and pick out the gastrodia in the soil around the nest wall.

Gastrodia planted in bed furrows can be excavated from one end to the other end. For bagged gastrodia, the bag is cut during harvesting, and all gastrodia is picked out by breaking the culture material by hand. When harvesting gastrodia, the size should be stacked separately, and the selected seed hemp should be cultivated or stored in time.

Gastrodia planting time and key points.

1. Planting time

Under normal circumstances, it is more suitable to be planted from November to March of the following year, and the climate and environment during this period are more suitable for growth, and it is best to choose when the weather is relatively sunny when planting.

2. Key points of planting

When gastrodia is planted, it is necessary to use tree species with solid wood and easy to receive bacteria as fungus, and broad-leaved trees can generally be selected, such as mistletoe, cork oak, water melon, birch, etc.

When choosing the cultivation site, Gastrodia gastrodia needs to choose a sandy loam soil with good ventilation and good drainage, and the slope should be light rain 45 degrees, and it is best to plant lead in a leeward and sunny place, which is extremely beneficial to its growth.

Gastrodia gastrodia this plant, is generally harvested while planting, the normal harvest period can be divided into winter and spring, the winter is harvested before the freeze, and the spring is harvested after the thawing, which can be determined according to the local climate characteristics, and the natural ripening season is in July and August every year.

Gastrodia takes 4-5 years from planting to harvesting, and if small cracks begin to appear on the ovary, it means that the seeds are ripe and ready for harvesting.

Gastrodia harvest time.

Generally speaking, the natural ripening season of gastrodia is in July and August every year, and now the number of wild gastrodia is decreasing, and the gastrodia on the market is mainly artificially planted.

The normal harvest period can be divided into winter and spring, harvesting before freezing in winter, and harvesting after thawing in spring, which can be decided according to the local climate characteristics.

Gastrodia is planted in several months.

1. Gastrodia gastrodia is a common Chinese herbal medicine, its best germination temperature is about 15, if the temperature is too low, there can be poor can affect the yield of gastrodia, so we must choose to sow when the temperature is suitable.

2. The best planting time for gastrodia is in March and April in spring, and August to September in autumn, these two time periods are the peak season for the growth of gastrodia, the climate is suitable and the temperature is stable, so we must seize the opportunity to sow seeds.

The first is to receive the goods carefully, to look around, not to miss the mature gastrodia, the second is to carefully cultivate the surface layer, to pull out the gastrodia and gently take it out, do not damage the gastrodia. The third is to pay attention to the time when processing, because it will reduce the medicinal value of gastrodia for a long time.

Answer] :d Harvesting and processing method of aconite: from late June to early August, the mother root, fibrous root and sediment are removed.

Red ginseng is harvested in the fall, washed, steamed, and dried.

Gastrodia is dug after winter to before Qingming in the following year, washed immediately, removed the coarse skin, steamed thoroughly, and opened to low temperature (below 60) to dry.
