How about the cultivation prospects and cultivation techniques of Tianma
In recent years, due to the market and price recovery of Gastrodia elata, coupled with some advertising exaggeration or false propaganda, the artificial cultivation of Gastrodia elata has been heated up, resulting in double the price of Gastrodia elata. Gastrodia elata is an orchid perennial herb, its growth and development has specific environmental conditions and material basis. First, Gastrodia elata is a typical heterotrophic type of higher plants, growth and development must be Armillaria mellea as "food". If there is no Armillaria mellea to supply "nutrition", Gastrodia elata bulbs will shrink due to hunger and die out in 2- 3 years. Therefore, artificial cultivation

Identification method of true and false Gastrodia elata
Gastrodia elata is a valuable traditional Chinese medicine. With the gradual shortage of wild Gastrodia elata resources, Gastrodia elata has been listed as a third-class endangered plant protected by the state. In recent years, although the artificial cultivation of Gastrodia elata has made rapid progress, due to the large demand, market shortage and strong prices, some lawbreakers take the opportunity to enter with the fake as the real one. For this reason, the identification methods of Gastrodia elata are introduced as follows: 1. True Gastrodia elata. There are eight characteristics: ⑴ underground tubers are oval or oval, usually long oval after steaming and drying, slightly flat, and some curved.

How to process Tianma fine
Gastrodia elata should be dug up with processing, because the storage time is long, gastrodia elata easy to run pulp, reduce the dry rate. Especially spring hemp can not be stored. Spring temperature is high, if not timely processing, but also moldy. When processing, first dig back the gastrodia elata soil with clean water, and then wipe the water with a cloth, and then put into the pot with fine sand together fried. Depending on the size of the pan (pan number one or pan number two), fry each pan with fine sand. According to the size of the pot (No.1 or No.2 pot), put 4-7.5 kg of fine sand and 1.5-2.5 kg of Gastrodia elata in each pot. By day.

A New Technique of Rapid Propagation of Gastrodia elata Hybrids by "Two Methods"
1. Breeding method of Tianma arrow bud mother in pot (Take Yidu Red Gastrodia elata as an example) 1. Potted seedlings: Before and after Qingming Festival, when the room temperature is stable above 15 DEG C, fresh and healthy wild red gastrodia elata arrow bud matrix (marked with wild red) and plain red gastrodia elata arrow bud matrix (marked with home red) with full bud top and no damage and weight of 100-150 grams are selected, and planted in plastic washbasin or enamel washbasin respectively with river sand. Four arrow bud matrix (plants) are evenly placed in each basin, and the arrow bud head (parrot mouth) is 3-5 cm away from the basin edge upward, covering 5- 5 cm.

Character Identification of Gastrodia elata and Gastrodia elata
In recent years, there are often similar plant tubers on the market, fish eyes mixed with beads, pretending to be Gastrodia elata. In order to reduce errors and purify the market, several easily confused characteristics of pseudo Gastrodia elata are introduced: "Parrot mouth, concave navel, outer ring dried ginger skin, rosin section to keep in mind." This is the formula for distinguishing whether Gastrodia elata is true or not. In this formula, the cross section of rosin is an important basis for judging the authenticity of Gastrodia elata. The dried tuber of genuine Gastrodia elata is long oval, often flattened and curved, 6-13cm in length and 2-6cm in diameter. There is residual stem base or reddish brown withered at one end.

Gastrodia elata has three main points to grasp for high yield
1, Armillaria mellea to "three new" 1, new technology: new methods to obtain new strains. The new method uses the latest biotechnology to detoxify strains, which is the most advanced method of obtaining strains so far. Traditional Armillaria mellea species, the best effect is obtained from tissue isolation or spore isolation, the general unit or individual is mostly using the purchased mother species for transformation and expansion, so the cultivation effect is not good. 2. New strains: pure isolated strains within three generations are required. The pure isolated strain referred to herein refers to

Cause and Control of Character Degeneration of Gastrodia elata
Degeneration of hemp characters often showed that the yield of arrow hemp decreased, the individual became smaller and slender, the yield of rice hemp and white hemp decreased greatly, ginger yellow or light brown, poor resistance, and the original yield and characters could not be fully reflected. The reasons are as follows: 1. Multi-generation asexual reproduction. Generally after 5~6 generations of asexual reproduction began to appear degradation phenomenon, but in different soil cultivation, degradation speed has differences, with granite soil cultivation of slow degradation, followed by yellow brown soil parent material, shale or limestone weathering formed acidic soil.

Why does Gastrodia elata have soft rotten nest? How to avoid the occurrence of this disease
Soft rot nest disease of Gastrodia elata is one of the reasons for its low and unstable yield in cultivation. Soft rot occurred in rice hemp, white hemp and arrow hemp, the tuber bark was yellow, the central tissue was rotten, and the section of the tuber exudated a stinky white serous liquid. Armillaria mellea is lush and dense in the burrow of Gastrodia elata and in the tuber. Gastrodia elata grows on Armillaria mellea. Why do soft rot nests and tubers fill with Armillaria mellea mycelium? In order to explore this problem, we should start with the nutritional ecology of Gastrodia elata. Gastrodia elata has no roots and no green leaves, and its autotrophic organs degenerate, which depends on Armillaria mellea.

Main measures of Field Management of Cotton in the later stage
Cotton generally began to open bolls in late August and early September (the End of Heat to White Dew), cotton management entered the later stage, and the main tasks of cotton field management in the later stage were to protect roots, leaves, promote early maturity and prevent premature senility, so as to achieve the goal of high yield and high quality and high yield and bumper harvest. 1. Timely watering to prevent autumn drought: if the soil moisture is insufficient in the later growth stage of cotton, it will affect the absorption function of the root system, the development of cotton boll is slow, the fiber and seeds can not mature normally, and the soil nutrients can not play a better role. Therefore, in case of autumn drought, it should be timely.

The field management of wheat and cotton should keep up with it.
First, the growth characteristics of wheat interplanting cotton. In view of the characteristics of wheat cotton intercropping, cotton seedlings after wheat are thin, slow in growth and development, late budding and flowering, easy to grow in the middle stage, and easy to mature late in the later stage, and the cotton seedling stage is affected by rainfall and low temperature, and the disease in the seedling stage is more serious. The field management after wheat must be based on the word-ldquo;-rdquo; and pay close attention to the word-ldquo;-rdquo; to promote the rapid growth and development of cotton seedlings so as to make up for the lack of growth at seedling stage. Second, snatch out the stubble and loosen the soil
