How do cattle vigorously seedlings sow? The cattle is a kind of medicinal material, which is rooted in medicine. The main ingredients are protein, starch and alkaloids. Because it is on the verge of exhaustion, the scale of vigorous cultivation of cattle is constantly expanding. For the vigorous cultivation of cattle, many people use the seeding and breeding. Let's take a look at the method of sowing and breeding of the cattle.
What kind of plant is cattle vigorously?
Niuqiang is a kind of medicinal material. It is a common medicinal and edible homologous plant distributed in Guangdong, Guangxi, Hainan and other places in China. In recent years, the resources of wild cattle have been exhausted, the scale of planting has been expanding, the demand for seedlings has been increasing, and relatively mature seedling cultivation techniques are urgently needed. At present, cattle breeding methods mainly include tissue culture and seed propagation. Although tissue culture and breeding techniques can achieve large-scale breeding of seedlings, their production operations are complicated and costly. It is not yet determined whether high yield can be achieved. Therefore, seed breeding is the current breeding enterprise and A method of nursery that farmers usually use. Due to the maturity of the seeds from December to February, the seed germination takes a long time, the germination rate is low under natural conditions, and the seedlings grow slowly, which is not conducive to the standardization and large-scale production of high-quality bovine vigorous seedlings, and is not conducive to the production of high-quality medicinal materials. .
Cattle vigorous seedling sowing and propagation method
1. Collect fully ripe pods, dry them, and pick out the cracked pods and shelled seeds in time, the un-cracked pods, gently pry them with pliers, and take out the seeds.
2. Choose seeds that are full, mature, free of mechanical damage, and free from pests and diseases.
3. Fresh seeds are immersed in warm water at 45 ° C for 4 hours.
4. Take the tray of suitable size and wash it with water; put the gauze block with the same specification of the tray in boiling water for 5min, take it out and let it cool; put 4 layers of wet gauze on the bottom of the tray to make the bovine vigorous seed evenly flat. Spread on gauze, spread the entire tray, and cover the seeds with 4 layers of wet gauze on the top.
5. Place the seeded tray in an incubator or an artificial climate chamber. The culture conditions are: temperature 40 ° C, humidity 85%.
6. Rinse the upper and lower gauze with water every day, wash the cultured seeds every 3 days, and pick out the rotten seeds. Rinse the intact seeds with clean water for 3 times until the surface of the seeds has no sticky feeling. Continue to follow the steps ( 4) and (5) culture and collect the germinated seeds [Jishan Huayao].
7. Dry the crushed coco peat in the strong light, mix it with the crushed tillage soil according to the volume ratio of 1:2, add 80kg of the national standard organic fertilizer per cubic mixture, mix well to make the seedling substrate; put the seedling substrate into the high In a 10 cm, 15 cm diameter seedling container, the seedling containers are placed neatly in the nursery.
8. Drill a 2cm hole in the seedling substrate. Place the seed in the hole with the bud facing down, cover the substrate with a thickness of 1cm, and pour water.
9. Set up a plastic small arch shed with a height of 50cm on the side of the raft, and compact it around. When the maximum ambient temperature is ≤20°C, place the seedling container that has been sown in a plastic small arch shed. When the maximum ambient temperature is >25°C, remove the plastic small arch shed; The whole seedling process controls the humidity at 80%.
10. When the seedling height is 11cm, spray 0.1% of the compound fertilizer aqueous solution every 12 days; when the seedling height is 35cm, prun the main stem to 12cm high, and cut off the side branches, pruning twice in the seedling stage; after 6 months of cultivation Can go out.
The above is about the introduction of cattle seedlings and breeding methods. The cattle have a high medicinal value, so many farmers will plant it themselves. In order to protect the farmers' benefits, this article analyzes this article and hopes to help More people who grow cattle.
It can prevent some medicine or blood from splashing on the face, thus protecting the eyes. This kind of glasses is generally used in conjunction with masks and surgical caps to fully protect the doctor's head.
[Functions of medical eye masks]
1. Prevent blood, potion and other liquids that cause damage to the skin from causing unpredictable damage to the eyes.
2. It can prevent the impact of objects on the eyes during close surgery.
3. The inner space of the eye mask is large enough for doctors who wear myopia glasses.
4. The breathability must be good, generally there are vents
