Gastrodia sexual reproduction four pool with the method of planting, is the Gastrodia seed, germinating bacteria, honey fungus strains, bacterial material together with the next pool. This companion planting method saves labor and time, increases the yield of gastrodia elata, and saves wood. If sowed before the beginning of June, it can grow into a white-headed hemp, and if it grows into a arrowhead, it will take only one and a half years.
Selection and storage of seedlings
Select the arrowhead buds that are full, fresh, rich in soil, no scars, no pests and diseases, and the weight of which is about 200g. After being dried, the moisture of the epidermis is dried and stored for spring planting. Indoor and outdoor storage can be, the key is to prevent freezing damage and rot. The water content of the medium-grained river sand used for buried arrowheads is 20%, and Ning Qian should not be wet in order to prevent the hemp seeds from rot. In outdoor storage, the place with good drainage, loose soil, and leeward sun should be selected. Indoor storage must be well ventilated. The size of the buried hemp area may be determined according to the amount of storage. Generally, a 35 cm deep bar-shaped cellar is suitable for outdoor use, and wooden box sand can be used indoors. Store a 10cm thick layer of coarse sand or cinder mixture at the bottom of the tank. Then lay a layer of medium-grained sand on it. Place it on the sand layer at a distance of 2cm. Place a layer of back cover with 5cm of sand and place it in the second place. Layer, so you can put 2 to 3 layers, then cover fine sand 10cm, surface cover rice, straw and other crop straw cold and warm, and regularly detect the moisture content of the covering material, adjust the humidity.
The cultivation of arrowhead
The use of greenhouse or greenhouse cultivation of arrowheads can be matured more than 1 month in advance, which is beneficial to early sowing (June), and can shorten the hemp cycle. Greenhouses and arch sheds can be modeled on the construction method of vegetable greenhouses, and the size can be determined according to the scale of cultivation. If a family makes a small amount of cultivation, it can be planted in the greenhouse in the natural season or in a greenhouse. However, no matter which method you use, you should choose a place with high ground, leeward, and ventilation.
In the case of arrowhead planting methods, 10cm thick coarse sand or cinder mixture (also known as culture material or culture substrate material) may be laid on the bottom of the tank, and then the arrowhead may be planted on the sand layer in the form of â€œgoodsâ€. The distance is 10cm. Don't injure the hemp skin and arrow buds when operating, otherwise it is very easy to cause germination. After cultivation, the surface is covered with 8cm thick sand and placed in a greenhouse or a shed to manage the breeding.
Management after arrow cultivation
1. Shade gastrodia is very sensitive to direct sunlight, direct light will cause the calyx to become dark, causing lodging. The best way to shading is to pull a black shading net with a 60% shade on the underside of the plastic film in the shed, and a small amount of breeding can be used to create a shading effect with four points of light and six shades of shading.
2. Moisturizing Gastrodia elata twitching, culturing, and fruiting is in the period from May to June. The moisture loss of the culture medium is relatively large. It is necessary to replenish the culture medium in time to keep the substrate moist instead of water stains.
3. The probability of the inflorescence at the top of the topping gastrodia elata is low, and the top â€œinflorescence tipâ€ should be removed after the initiation of budding, which can reduce the loss of nutrients and make the whole plant full and ensure the seed quality.
4. Anti-lodging gastrodin hollow, generally 200g heavy arrowhead, with a height of about 1m, in case of wind or fruit pods are easily broken, it is very important to insert rod fixed.
Because of the special structure of gastrodin, anthers (ie, pollen) are covered by caps, caps do not fall off on their own, and anthers do not spread spontaneously when they are sticky. In particular, there are few insect transmission activities in greenhouses or greenhouses. Therefore, artificial pollination must be performed. When artificial pollination is carried out in Tianma, in order to ensure the success rate of pollination, the principle of opening one flower should be followed, and the pollination time is best from 10:00 to 14:00. While pollinating, gently squeezing the ovary, the other hand presses the lip with a bamboo stick, and then picks out the anther block and accurately places it on a smooth stigma. Flush, same plant or different flowers, different plants can be pollinated. Cross-pollination hybrids have a strong advantage and high yield. Artificial pollination as long as the operation procedures, the general pollination success rate of 90%.
The seeds of Gastrodia elata grow from the bottom up and are gently pinched by hand. When the seed is soft and the seed coat longitudinal cracking line is fissured, it shows that several pods in the upper part of it have also matured and should be harvested in time. The harvested seeds are best harvested with the broadcast, and should be broadcast at the latest 3 to 4 days before the splitting of the vertical split line. If it cannot be finished for a while, it is better to store it in a refrigerator at about 4Â°C, and it is forbidden to expose the fruit. Seeds in mature pods are loose, light grayish yellow, and are the best sowing period before fruit cracking. Premature seeds are white and immature will not spread; too late seeds are brown and have lost germination rate. If seeds are sown in germinating bacteria in plastic bags, sowing time can be extended.
Preparation before sowing
Prepare 30-kilograms of fresh-stemmed rods with a diameter of 3 to 10 cm and a length of 60 cm per square meter, soak them in 0.25% ammonium nitrate solution for 6 to 12 hours, and chop the fish scales at intervals of 3 to 7 cm on a wooden stick. 3 sides. 400kg of clean and non-polluting medium and coarse grain river sand per square meter is required. The river sand should be rinsed with clean water for 6 hours before use. 1kg of eucalyptus leaves should be used per square meter, and water should be dipped in water for 4 hours before use to drain excess water. For standby use, 3kg of twigs with a diameter of 1.5cm and a length of 6cm should be used per m2. In addition, 4 bottles of high-quality armillaria species, 2 bottles (or 2 bags) of germinating bacteria, and 16-20 pieces of gastrodia elata should be used per square meter.
The key task before sowing is to fully stir the germinating bacteria and the seeds of the gastrodia. During the operation, the germinating bacteria (the medium used for the defoliation of the eucalyptus leaves used for the seed production of the germinating bacteria) are first cut into small pieces of 1.5 cm square with a knife. Block, and then put into a clean pot, gently pinch the fruit so that the longitudinal split line split, cast the seeds of Gastrodia elata in the basin germination bacteria, and then use their hands to turn and mix, shake off one pod and mix it again, and The crushed minced fruit skin is also sprinkled into the germinating bacteria and mixed until ready for sowing. This work should be done in a windless environment to prevent tiny seeds from being blown away by the wind.
When sowing, first in a greenhouse or in a shed, bricks are used to make a width of 100cm, a height of 40cm, and a gastrodia cultivation pond with the length of a greenhouse or arch shed. Then, 10cm thick coarse sand is laid on the floor of the pond and the leaves are soaked in water. Sprinkle a layer and shoot a flat, and then spread the germination bacteria pieces mixed with the gastrodia seeds evenly on the leaf layer, and then put a beech bar with cut off the scales mouth on the sowing layer, and the bar and the bar are separated by 5cm, generally Place 9 or so (15kg), and then place the armillaria species on both ends of the scales and on both ends of the sticks, and then place the small sticks diagonally between the sticks to guide the honey fungus On the stick, after the above process is completed, gently cover the river sand about 5cm thick, and then use the same method to sow the second layer (also can be sowed in a single layer). The top layer covers the river sand 10cm thick and shoots flat.
After the planting, the sheltering protection shall be carried out first. The shade net with a shading rate of 80% may be used to cover the top layer and the surrounding area, and crop straw or shrub branches may be used to create a cool environment for the growth of Gastrodia elata and Armillaria mellea. And security over summer. According to tests, with good shading outside, the temperature between the summer gastrodin and the surface generally does not exceed 27Â°C. The ventilated indoor gastrodia and the surface temperature do not exceed 26Â°C, and the gastrodia grows well and the yield is high. Followed by moisturizing problems, the moisture content of sand after inoculation is about 55%, which is conducive to the growth of two bacteria and hemp seeds. One week after sowing, water can be sprayed on the surface of the Tianma cultivation pond once. After 1 month, water can be sprayed on the surface of the Tianma cultivation pond once. At the same time, the cultivation place should be well ventilated, especially the indoor cultivation must be ventilated regularly, which will play a good regulatory role in preventing the infection of the pathogenic materials and promoting the longevity of the seedlings.
Respiratory disease is a common disease, frequently-occurring disease, the main lesion in the trachea, bronchi, lung and chest, lesions are more cough, chest pain, respiratory effects, severe breathing difficulties, hypoxia, and even respiratory failure and death. Due to air pollution, smoking and other factors, The chronic obstructive pulmonary disease is increasing including chronic bronchitis, emphysema, pulmonary heart disease, bronchial asthma, lung cancer, pulmonary diffuse interstitial fibrosis, and pulmonary infection the morbidity and mortality of the disease at home and abroad . Therefore, Anti-Respiratory disease drugs are also more and more attention paid by researchers. Respiratory disease have the symptoms of cough, sputum, hemoptysis, chest pain, shortness of breath and other symptoms of lack of specificity, often clinicians mistaken by people for colds, bronchitis, and severe pneumonia, tuberculosis or lung cancer and other diseases delayed diagnosis; Respiratory tract infection, to be developed to emphysema, pulmonary heart disease, respiratory failure was taken seriously, but it was too late, its pathology and physiological function has been difficult to reverse. As with other systemic diseases, careful and detailed medical history and physical examination are the basis for the diagnosis of respiratory diseases, and should be combined with routine laboratory tests and other special findings to conduct a comprehensive and comprehensive analysis. Currently the most clinical application of anti-respiratory disease drugs have the following four categories: 1. Antihistamines 2. Cough medicine 3. Bronchodilator 4. Expectorant 5. Anti-asthma Drugs.
