Abstract
Description
Technical Field
[0001] The invention relates to the technical field of vegetable planting, and in particular to a method for cultivating selenium-enriched bitter vegetable sprouts. Background Art
[0002] Spring bitter herbs are very popular in northern Shaanxi. The market demand for bitter herbs before Qingming Festival is strong and the price is considerable. They have a unique taste of crispness, refreshingness and slight bitterness. Paired with salt-soaked almonds, they are a delicious and healthy cold dish. Dandelions are rich in nutrients such as protein, carbohydrates, calcium, iron, zinc, vitamin A, vitamin C, and have medicinal functions such as anti-inflammatory, lowering blood lipids, and anti-oxidation. Traditional Chinese medicine believes that they have the effects of clearing heat and detoxifying, cooling blood and improving eyesight.
[0003] However, traditional sprouts are mostly cultivated in containers, relying on water, inorganic fertilizers and chemicals, and it is difficult to ensure the organic and healthy vegetables. At present, the cultivation method of wild sowberries into organic and selenium-rich sowberries while avoiding the use of chemical pesticides, hormones and chemical fertilizers still needs to be improved, and the present invention aims to fill this technical gap. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a method for cultivating selenium-enriched bitter vegetable sprouts.
[0005] In order to solve the above technical problems, the technical solution provided by the present invention is a method for cultivating selenium-enriched bitter vegetable sprouts, comprising the following steps:
[0006] Step 1) Seedbed construction: In the greenhouse, dig a pit 7.5 meters long, 1 meter wide and 0.3 meters deep, build 24-25 cm high walls with bricks on all sides of the pit, and evenly spread a layer of 0.03 meter thick nutrient soil on the bottom of the seedbed;
[0007] Step 2) Sowing and raising seedlings: Sow the bitter vegetable seeds in the seedbed and cover the seeds with a thin layer of fine soil after sowing. After the seeds emerge, carefully cultivate them to make the bitter vegetable seedlings strong and roots strong until the bitter vegetable root diameter reaches 2-3 mm;
[0008] Step 3) Preparation of nutrient soil: Take nutrient soil and add 10%-15% of boiled almond water to it, and stir it evenly to make the nutrient soil moist. If the nutrient soil is too dry, add an appropriate amount of rootless water, stir it evenly again, and pile it into a trapezoidal shape for natural fermentation. Punch holes downward from the upper end of the trapezoidal nutrient soil pile, with an air hole every 0.3 meters, and then cover it with plastic film until the fermentation is completed and set aside;
[0009] Step 4) Cutting and covering with soil: When the bitter vegetable seedlings reach the specified standard, cut off the bitter vegetable heads, prepare the seedbed, and cover the seedbed with a layer of fermented nutrient soil with a thickness of 0.2-0.25 meters;
[0010] Step 5) Add nutrient solution: Take 1 catties of almonds and 2 catties of black beans, crush them, soak them in appropriate amount of water for one day and filter them. Pour the filtered solution into the seedbed by drip irrigation;
[0011] Step 6) Temperature control: Control the temperature of the seedbed within a standard range. When the temperature is low, the growth rate of the bitter vegetable sprouts is slow, and the resulting sprouts are thick and strong; when the temperature is high, the growth rate of the bitter vegetable sprouts is fast, and the resulting sprouts are relatively slender;
[0012] Step 7) Harvest management: After 25-28 days of cultivation, check the growth of the bitter vegetable sprouts, and harvest them before they emerge. In the greenhouse, a 0.5-0.7 meter management channel needs to be reserved between the seedbeds, and multiple seedbeds can be built in sequence. When covering the seedbeds with nutrient soil, cover one bed every 2-3 days to stagger the harvest time and achieve daily harvesting and sale of selenium-rich bitter vegetable sprouts. After harvesting, cover the bitter vegetable seedbed with 0.2-0.25 meter thick nutrient soil again, and harvest again after another 25-28 days of cultivation.
[0013] Furthermore, in step 2, the spacing between the bitter vegetable seeds in the seedbed is 0.03-0.05 meters, and the row spacing is 0.08-0.1 meters.
[0014] Furthermore, the nutrient soil is a mixture of 33-38% of microbial fertilizer and 62-67% of cooked soil.
[0015] Furthermore, in step 6, the temperature of the seedbed is 4-20°C.
[0016] The advantages of the present invention compared with the prior art are:
[0017] 1) Organic and healthy: This cultivation method does not use chemical pesticides, hormones and chemical fertilizers. The soil is fermented, the fertilizer is natural organic fertilizer, the water is rootless water, and the trace element selenium applied is purely natural, ensuring that the cultivated selenium-rich bitter vegetable sprouts are organic and healthy;
[0018] 2) Rich in nutrition: Dandelion sprouts grow in the soil and can absorb various nutrients and trace elements in the soil. Compared with sprouts grown in traditional containers, they are more nutritious and taste better;
[0019] 3) Staggered harvesting: By rationally arranging the time for covering the seedbed with nutrient soil, the harvesting time can be staggered to ensure that selenium-rich bitter vegetable sprouts are harvested and sold every day, thereby improving economic benefits. DETAILED DESCRIPTION
[0020] The following is a further detailed description of the method for cultivating selenium-enriched bitter vegetable sprouts of the present invention in conjunction with the embodiments.

[0023] Seedbed construction: dig a 7.5m long, 1m wide and 0.3m deep pit in the greenhouse, and build 25cm high walls around the pit with bricks. Spread the nutrient soil mixed with 35% microbial fertilizer and 65% cooked soil evenly at the bottom of the seedbed, with a thickness of 0.03m.
[0024] Sowing and seedling raising: Sow the bitter vegetable seeds in the seedbed with a spacing of 0.04 meters between plants and 0.09 meters between rows, and cover with a thin layer of fine soil after sowing. After the seeds germinate, carefully cultivate them until the diameter of the bitter vegetable roots reaches 2.5 mm.
[0025] Preparation of nutrient soil: Take the above nutrient soil, add 12% boiled almond water to it, and stir evenly. If the nutrient soil is dry, add an appropriate amount of rootless water, stir again and pile it into a trapezoidal shape. Punch an air hole every 0.3 meters at the top of the trapezoidal nutrient soil pile, cover it with plastic film for natural fermentation.
[0026] Cut the heads and cover the soil: When the dandelion seedlings reach the standard, cut off the dandelion heads, tidy up the seedbed, and cover the seedbed with fermented nutrient soil with a thickness of 0.22 meters.
[0027] Add nutrient solution: Take 1 pound of almonds and 2 pounds of black beans, crush them, soak them in water for a day, then filter them, and pour the filtered solution into the seedbed by drip irrigation.
[0028] Temperature control: Keep the temperature of the seedbed at 12℃.
[0029] Harvest management: After 25 days of cultivation, the bitter vegetable sprouts are harvested before they emerge. In the greenhouse, a 0.6-meter management channel is reserved between the seedbeds. A bed of nutrient soil is covered every 2 days to achieve staggered harvesting. After harvesting, the bitter vegetable seedbed is covered with 0.22-meter-thick nutrient soil again, and harvested again after 25 days. In winter, hibernation time for wild vegetables must be reserved. The harvested bitter vegetable sprouts are pure white.
