Selenium-rich planting method for radix codonopsis lanceolatae from Taishan mountain and special selenium-rich fertilizer

Abstract

The invention discloses a selenium-rich planting method for radix codonopsis lanceolatae from Taishan mountain and a special selenium-rich fertilizer. The method comprises three steps of young seedling and seminal root cultivation of the radix codonopsis lanceolatae from Taishan mountain, selenium-rich mature seedling cultivation and management of the radix codonopsis lanceolatae from Taishan mountain and harvesting and processing. The special selenium-rich fertilizer is prepared by mixing the following substances in percentage by weight: 25% of controlled release urea with controlled release time of 180d, 9% of calcium superphosphate, 15% of potassium sulfate, 25% of humic acid, 25% of a fully fermented pepper stalk and chrysanthemum straw mixture, 0.5% of sodium selenite and 0.5% of calcium oxide. According to the method, the special selenium-rich fertilizer for soil and the radix codonopsis lanceolatae from Taishan mountain is applied to the soil, and inorganic selenium is absorbed and converted by the radix codonopsis lanceolatae from Taishan mountain to form biological organic selenium, so that the selenium content of the radix codonopsis lanceolatae from Taishan mountain is increased; the selenium-rich treatment is carried out with combination of two methods for applying selenium to the soil and spraying selenium to the leaf surfaces, so that the immobilization and loss of selenium in the soil are reduced.

Description

technical field [0001] The invention relates to the planting technology of Chinese medicinal materials. Background technique [0002] Codonopsis lanceolata Benth.et Hk.F is a perennial herb belonging to Codonopsis lanceolata (Campanulaceae). It is mainly produced in Shandong, Heilongjiang, Guangxi, Zhejiang, Jiangxi, Fujian and other places. The health care effect is the best. Codonopsis verticillum has four leaves, and the Codonopsis verticillum produced in Mount Tai has been called Taishan four-leaf ginseng since ancient times. It is listed as the "Four Famous Medicines of Mount Tai" together with Polygonum multiflorum, Polygonatum, and Comfrey. Taishan four-leaf ginseng is rich in various vitamins, trace elements, saponins, polysaccharides, flavonoids and other medicinal ingredients. Insufficient milk, mastitis, lung abscess, carbuncle sore and swelling. Modern pharmacological studies have shown that Taishan four-leaf ginseng has anti-oxidation, anti-tumor, and enhance...

AI Technical Summary

Problems solved by technology

The spring seedlings of Taishan four-leaf ginseng have the following disadvantages: ①Because of the drought, lack of rain and unstable temperature in spring, the seedlings need frequent watering, and the emergence rate is low, the seedlings grow slowly, and the phenomenon of lack of seedlings and broken ridges often occurs; ②Taishan four-leaf ginseng Seedlings like shade and need artificial shading; ③The seedlings grow for a long time, and when the vines above the ground are 80-100 cm long in late August, they need to be erected, otherwise "covering seedlings" and dead seedlings will occur

If the amount of inorganic selenium is too small, the selenium-enriching effect cannot be achieved. If the amount of inorganic selenium is too small, the content of mineral elements and amino acids in plants will change, resulting in selenium poisoning, production reduction and even death.

There is no precedent for the successful cultivation of selenium-rich ginseng in Mount Tai.
