What environment does gastrodia like to grow in?

Gastrodia prefers a cool and humid environment, is cold-tolerant, and is afraid of high temperatures. Gastrodia has no roots, no chlorophyll to absorb and produce nutrients, and must rely on honey ring bacteria to provide it. Honey ring fungus is a facultative fungus that often parasitizes or saprophytes in the roots and tissues of old trees.

It starts to grow at 6 8 o'clock, can grow normally when the soil moisture is 60 -80 and the temperature is 20 20, the optimal temperature for growth is 20 26, the growth is slow above 28, and the growth stops above 32. Gastrodia and Honey Ring are in a nutritional symbiotic relationship. The mycelium invades the epidermal tissue of the gastrodia tuber, the top of the mycelium is ruptured, and the hyphae invade the parenchyma cells of the cortex, decomposing and absorbing the epidermal cells, and the hyphae continue to stretch inward, then the hyphae are decomposed and absorbed by the cells of the digestive layer of Gastrodia gastrodia for the growth of Gastrodia.

Gastrodia gastrodia grows best at 20 25, and growth above 30 is inhibited. In spring, when the ground temperature reaches 10 or more at 15 cm, the geragia bud head begins to germinate and begins to reproduce hemp. Growth is rapid in June and July, slows down in September, and enters dormancy in late October when the ground temperature drops below 10.

It takes 4-5 years from seed to flowering.

Gastrodia seeds have no endosperm, the embryo is undifferentiated, and they cannot provide nutrients for germination**, under natural conditions, seed germination needs to be participated by fungi in addition to the conditions required by ordinary green plants. Under natural conditions, the seeds germinate at 10-20 o'clock in early May, but the germination rate is very low, generally 1 10, if the newly harvested seeds are stored in low temperature (5) dry and closed storage conditions for 180 days, the germination rate of 50 can still be maintained.

It is advisable to choose gentle slope land and valley valley land rich in organic matter that is half yin and half yang, and well-drained sandy loam or sandy soil, especially wasteland.

Soil texture has a great impact on the growth of gastrodia, honey ring fungus likes high humidity environmental conditions, but gastrodia is afraid of water flooding in the soil, poor drainage of cohesive soil, especially in the rainy season, it is easy to accumulate water, long-term water accumulation in the hole Gastrodia gastrodia will be infected and rotted, so it is advisable to choose sandy soil and sandy loam soil to plant gastrodia and culture beds. However, the growth of gastrodia still needs to have water continuously**, so in the year of drought, the yield of gastrodia cultivated in sandy loam soil is high, and in the year of rain, the gastrodia cultivated in sandy soil is abundant.

Gastrodia is a perennial tall plant, the plant can grow to 2 meters high, the fruit is obovate-oval, the underground tuber is rotten and old-fashioned, the flesh is oval, its tuber is gastrodia, the color is orange-yellow, some studies have shown that gastrodia has the effect of enhancing memory and brightening the purpose, and can be used for Alzheimer's disease, and the effect is significant.

Gastrodia is a tall perennial plant that can grow up to 2 meters tall, the fruit is obovate-oval, and the underground tuber is generally oval, and its tuber is Gastrodia, which is orange-yellow in color.

1. Growth habits

Gastrodia gastrodia is the underground tuber rhizome of the orchid plant Gastrodia, and its aboveground part has no green leaves, no roots, and cannot carry out photosynthesis, and its nutrition ** depends on the honey ring fungus**.

2. Composition and pharmacology

Gastrodia is flat, returns to the liver meridian, relieves wind, dispels wind and channel, can be the best headache, dizziness and high blood pressure, gastrodia for the heart is also very effective, some studies have shown that gastrodia has the effect of enhancing memory and bright purpose, can be used for Alzheimer's disease, the effect is significant.

3. How to buy gastrodia

There are many varieties of gastrodia, how to choose a good one, when we choose gastrodia, you can first look at the shape of gastrodia, the outer hunger leakage table of gastrodia is oblong and has buds at both ends, which is not easy to rot when cooking, and does not stick to the teeth when chewing, there is a very crisp feeling, and there is an acidic smell, it is likely to be smoked with sulfur.

4. Edible as traditional Chinese medicine

Gastrodia is generally beaten into powder, taken with warm water or milk, there is also to make pigeon soup, wash the pigeon and put it in the pot, in addition to gastrodia can also be put into red dates and wolfberry, ginger slices to remove the fishy, turn to low heat and simmer slowly after boiling, there is a regulation of the human brain nervous system, relieve stress, improve sleep, but also light spots and beauty.

1. Temperature management: wild gastrodia gastrodia only begins to germinate at 10-15 years old, and stops growing when it exceeds 30. 2. Suitable humidity:

If the soil moisture content is too low, gastrodia will be thin and wilting. 3. Soil conditions: loose and well-drained sandy loam soil is appropriate.

4. Reproduction mode: divided into two types: sexual reproduction and asexual reproduction.

1. Temperature management

Wild wild Gastrodia mainly relies on the reproduction and growth of Gastromycetes, which has certain requirements for temperature, among which Gastrodia gastrodia begins to grow in the environment of 6-8, while Gastrodia gastrodia begins to germinate at 10-15, and the growth of the two is fastest at 20-25, and stops growing when it exceeds 30.

2. Suitable humidity:

The growth of wild gastrodia requires a certain amount of humidity, the soil water content is too low, the growth of the dense ring fungus is poor, and the phenomenon of gastrodia gastrodia will be thin and wilted, if the moisture in the soil is too large, the oxygen content in the soil will be reduced, which will lead to the rot of wild gastrodia.

3. Soil conditions

Wild gastrodia has very high requirements for soil, and the soil quality is suitable for loose and well-drained sandy loam or sandy soil, especially wasteland, and it is necessary to ensure that the pH value of the soil is between 5-6, avoid clay and waterlogged waterlogged land, and avoid heavy stubble.

4. Reproduction methods

There are two modes of reproduction of wild gastrodia, namely sexual reproduction and asexual reproduction, in which asexual reproduction requires the selection of high-quality wild gastrodia as a cultivated species, planting it in humus-rich soil, and covering it with soil.

It is suitable for a relatively shady environment, so it is necessary to ensure that the temperature is controlled at about 23, and in the process of growth, it is also necessary to water more, and you can fertilize appropriately.

Be sure to pay attention to the temperature, be sure to water more and fertilize more when planting, and at the same time ensure the time of sunshine, only in this way can you grow better.

Gastrodia needs a warm environment and moist soil with a humidity of about 25% to grow.

I like places with lower temperatures, wetter places, and sandy soils, so that the yield of gastrodia will be high.

You need a cold and wet environment, and such an environment is relatively easy to find.

What is the influence of topography on the growth of gastrodia? Water is the main component of gastrodia tubers, and the water content of gastrodia is generally 65% to 80%. Gastrodia has different water requirements in different growing seasons:

At the beginning of April, the tubers begin to germinate, and the honey ring fungus needs to grow vigorously, so that Gastrodia gastrodia can be inoculated in time, so it is necessary to water to keep the soil moist and make Gastrodia germinate and grow normally; In the peak growth season of Gastrodia gastrodia in June and August, more water is needed, and abundant rainfall or timely irrigation can ensure soil moisture, which can ensure the high yield of Gastrodia; In late September, when there is too much rain or excessive watering, the growth of Honey Ring Fungus is vigorous, and Gastrodia gastrodia will be inhibited by Honey Ring Bacteria. The annual precipitation in the production area is more than 1000 mm, and the average relative humidity is about 80%. The rainy and humid climatic conditions are the most suitable for the growth of gastrodia.

The soil moisture content in Gastrodia gastrodia production areas is quite different among different textures: the water content of humus-rich soil is often maintained at more than 50%; In weathered stone muck, the soil moisture content is only 14% to 18%. Generally, the soil moisture content of gastrodia cultivation is 60% 65%, and the cultivation of weathered stone residue should be watered frequently.

The height of dry ground and total ground is closely related to climatic conditions. When the altitude is too high and the temperature is too low, Gastrodia gastrodia grows slowly; At low altitudes and in the hot summer, the growth of Honey Ring and Gastrodia will be inhibited. High temperatures at low latitudes in southwest China.

Moist soils favor wild production areas of Gastrodia. The distribution and yield of Gastrodia gastrodia are closely related to the land and topography, mainly because the land and the land directly affect the change of temperature, the growth environment of the spores of Gastrodia gastrodia melicia, and the terrestrial Gastrodia and Gastrodia gastrodia are both hot and humid environments, which can grow in mountainous areas at an altitude of 600-2000 meters.

Effects of moisture, air, and soil requirements on the growth of Gastrodia. The altitude and climatic conditions of Gastrodia gastrodia are the main factors affecting the growth of Gastrodia, and the growth environment of Gastrodia gastrodia is cold in summer and not very cold in winter. It is temperature sensitive.

The temperature will directly affect the growth of Gastrodia, the temperature will gradually decrease from south to north, the altitude of Gastrodia gastrodia distribution will also gradually decrease, and Gastrodia gastrodia grows in a cold and humid environment.
