Huperzia serrata cultivation nutrient solution

Abstract

The invention discloses huperzia serrata cultivation nutrient solution. The nutrient solution contains the following substances in concentration: 500-800 mg / L of calcium nitrate tetrahydrate, 500-600 mg / L of potassium nitrate, 400-500 mg / L of potassium dihydrogen phosphate, 300-400 mg / L of magnesium sulfate heptahydrate, 700-800 mg / L of iron sulfate heptahydrate, 200-300 mg / L of boric acid, 80-100 mg / L of copper sulfate, 350-450 mg / L of zinc sulfate and 100-150 mg / L of manganese sulfate, wherein the pH value of the nutrient solution is 3.9-4.2. By applying the huperzia serrata cultivation nutrient solution, the growth of huperzia serrata can be promoted to obviously increase plant height and root length of the huperzia serrata, the survival rate of the huperzia serrata is increased by over 80 percent, and the problem of difficulty in manual introduction cultivation of the huperzia serrata is solved well.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a nutrient solution for Melaleuca tower cultivation.

AI Technical Summary

Problems solved by technology

Drugs such as Huperzine A Tablets and Huperzine A Capsules that have been on the market and the upcoming Shiprin all require a large amount of Huperzine A. However, the cost of synthesizing Huperzine A is high, and the main source is wild Melaleuca. The content of huperzine A in Melaleuca is extremely low (usually only 5 / 100,000), and there has not been any other natural product that can replace Melaleuca, which leads to the shortage of medicinal materials in Melaleuca, which has become a restrictive drug for huperzine A. development bottleneck

[0003] Wild Melaleuca is mostly distributed in places with an altitude of 800-1300m, which requires high environmental conditions such as light and humidity, resulting in a narrow distribution area, mostly in wetlands under the shade, mossy coniferous forests and mixed coniferous and broad-leaved forests Growth, artificial introduction and cultivation are extremely difficult
