Problems solved by technology

[0003] In recent years, the scale of industrial planting of Astragalus membranaceus has been expanding year by year, but the scale and technology of Astragalus membranaceus seedlings are seriously lagging behind. At present, it is generally still in the traditional extensive original seedlings and planting stage.

Embodiment 1

[0019] Prepare the special nutrient solution for soilless green seedling cultivation of Astragalus membranaceus, and each liter of nutrient solution includes the following components:

[0020]

[0021]

[0022] In mid-July 2012, Tianjiahe Society, Wangzhuang Village, Biyan Town, Longxi County, Dingxi City, Gansu Province chose a flat land as a seedling test base. Adopt the soilless green seedling raising method of Astragalus membranaceus. After the cotyledons of Astragalus membranaceus germinate and replace to 3 leaves, the nutrient solution will be supplied. According to the nutritional needs of seedling growth, the nutrient solution will be sprayed 3-6 times a month, and water will be replenished according to the humidity of the seedling bed. , turn on sprinkler irrigation for 0.5-3 hours, sprinkler irrigation 2-3 times a week, and control the temperature in the greenhouse at 16-30 degrees Celsius during the growing season; in March 2013, the seedlings were dug out for ...

Embodiment 2

[0023] Embodiment 2: prepare Astragalus membranaceus soilless green seedling-raising special-purpose nutrient solution, every liter of nutrient solution comprises the following components:

[0024]

[0025]

[0026] Use the seedling-growing greenhouse of Example 1, adopt the Astragalus membranaceus soilless green seedling raising method, sow in early April, 2013, after the cotyledons of Astragalus membranaceus seeds germinate to 3 leaves, start to supply the nutrient solution, according to the nutritional needs of seedling growth, every month Spray and irrigate the nutrient solution 3-6 times, and supplement water according to the humidity of the seedling bed. Start the sprinkler irrigation for 0.5-3 hours, and spray 2-3 times a week. During the growing season, the temperature in the greenhouse is controlled at 16-30 degrees Celsius; in 2014 In March, the seedlings were dug out for transplanting into the field, and 3605 kg of Astragalus seedlings with healthy roots and no...

Embodiment 3

[0027] Embodiment 3: prepare Astragalus membranaceus soilless green seedling-raising special-purpose nutrient solution, every liter of nutrient solution comprises the following components:

[0028]

[0029] Use the seedling-raising greenhouse of embodiment 1 and embodiment 2, adopt the Astragalus membranaceus soilless green seedling raising method, sow in early April, 2014, after the cotyledons of Astragalus membranaceus seeds germinate to 3 leaves, start to supply nutrient solution, according to the seedling growth nutrition Demand, spray the nutrient solution 3-6 times a month, and supplement the water according to the humidity of the seedbed, start the spray irrigation for 0.5-3 hours, spray 2-3 times a week, and control the temperature in the greenhouse at 16-30 degrees Celsius during the growing season In March 2015, the seedlings were dug out for transplanting to the field, and 3542kg of astragalus seedlings with healthy roots without forks were produced, equivalent to...

Abstract

The invention relates to a nutrient solution specially used for soilless green seedling growing of astragalus membranaceus. The solution comprises potassium dihydrogen phosphate, magnesium sulfate, calcium sulfate, ferric sulfate, EDTA, boric acid, manganese sulfate, potassium nitrate, zinc sulfate, copper sulfate, molybdic acid and purified water. Combination of the components contains major and trace elements essential for growth and development from astragalus membranaceus seedlings to formation of young plants. A water dissolved substance of the nutrient solution is free of chemical compounds or ions having toxic or side effects or pesticide residues. Through adopting the nutrient solution, prepared branchless astragalus membranaceus plants for planting can be 99% or above, the root length of astragalus membranaceus plants for planting when one crop is grew in one year reaches 40-46 cm, the root length of astragalus membranaceus plants for planting when two crops are grew in one year reaches 35-40 cm, the yield per mu when one crop is grew in one year can reach 4500-5500 kg, and the yield per mu when two crops are grew in one year can reach 3500-4500 kg. Compared with traditional astragalus membranaceus seedling growing methods, the nutrient solution increases the yield per mu, avoids soil-borne diseases, and provides strong supports for large-scale development of the astragalus membranaceus seedling growing industry.

Description

technical field [0001] The invention relates to the technical field of agricultural economic crop breeding, in particular to a special nutrient solution for soilless green seedling raising of Astragalus membranaceus. Background technique [0002] Astragalus and ginseng are both good Qi-invigorating medicines in traditional Chinese medicine. There is a popular saying among the people that "drink Astragalus soup often to prevent diseases and maintain health". Modern medical research shows that astragalus can enhance the body's immune function, protect the liver, diuresis, anti-aging, anti-stress, lower blood pressure and a wider range of antibacterial effects, can eliminate experimental nephritis proteinuria, enhance myocardial contractility, regulate blood sugar levels, Astragalus can not only dilate coronary arteries, improve myocardial blood supply, improve immune function, but also delay the process of cell aging. Astragalus is easy to eat. It can be decocted in soup, dec...
