Description
Technical Field
The invention belongs to the technical field of hemp planting in the medical industry, and particularly relates to a hemp plug seedling substrate in the medical industry.
Background
Industrial cannabis refers to cannabis with a Tetrahydrocannabinol (THC) content of less than 0.3% which is an annual upright herb plant of the cannabis family, cannabis. According to international standards, cannabis with THC content > 0.5% is called recreational cannabis, 0.3% to 0.5% is called intermediate cannabis, and < 0.3% is called industrial cannabis. On the basis, the concept of the industrial cannabis for the pharmaceutical industry is defined, namely that the industrial cannabis with the THC content less than 0.3 percent and the Cannabidiol (CBD) content is called the industrial cannabis for the pharmaceutical industry (plum autumn, Mengying, Chenthrene. germplasm resources classification and research strategy of the pharmaceutical cannabis. China Chinese medicine journal, 2019, 44(20): 4309-. Wherein CBD is a non-psychoactive component of cannabinoid, has no hallucinogenic effect, and has medicinal value. Has wide application in the fields of food, daily chemicals and medicines and wide economic prospect. However, the content of CBD contained in the hemp in the pharmaceutical industry of China is far lower than that of foreign varieties, the cost for introducing the foreign varieties is high, meanwhile, the matched cultivation technology is incomplete, particularly in the seedling raising technology, the emergence rate is low, the apical dominance is serious, the later growth and development of plants are seriously influenced, and further the yield and the quality are influenced.
At present, the hemp used in the medicinal planting industry of China is mostly planted in an open field direct seeding mode, and the seed resource is seriously wasted. Some planting bases and research institutions directly use vegetable seedling raising soil for seedling raising, the deep analysis of the physicochemical properties of the matrix is lacked, and the optimal proportion suitable for the growth of the hemp seedlings in the pharmaceutical industry is difficult to determine.
