specific Embodiment approach 1

[0027] Specific implementation mode 1: The high-efficiency production method of the feminized seeds of medicinal industrial hemp in this implementation mode is realized according to the following steps:

[0028] 1. Required facilities:

[0029] Greenhouses and terrestrial greenhouses. Roller blinds with side ventilation.

[0030] Second, the choice of seedling time:

[0031] Feminized cannabis seeds of the same product are selected to produce female flower seeds in early spring, and the induced strains are raised in the greenhouse every 7 days. Do this in three batches. After 14 days, the seedlings of the pollinated plants were carried out.

[0032] 3. Induced plants are planted alone

[0033] After induced plant seedlings were transferred to individual greenhouses for cultivation.

[0034] 4. Implementation and installation of greenhouse shading

[0035] The shading film is installed in the greenhouse, and the closed space formed after activation has no visible light. ...

specific Embodiment approach 2

[0049] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 2, when the medicinal industrial hemp plants are flowering and pollinating, greenhouses are used to reduce production costs, and through manual control, there is no other pollen pollen in the air. Production, no other pollen pollution, guaranteed feminization rate.

specific Embodiment approach 3

[0050] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that in step three, select the same product of feminized cannabis to produce female flower seeds, start seedling cultivation in early spring, and induce seedlings to grow seedlings in the greenhouse every 7 days. Do this in three batches. After 14 days, the seedlings of the pollinated plants were carried out.

[0051] Supplementary lighting should be carried out during the cultivation of cannabis seedlings, and the lighting time should be guaranteed to be 18 hours.

Abstract

The invention relates to a method for effectively improving the yield of female seeds of cannabis sativa in the medical industry. The production method aims at solving the problem of the yield of the female seeds of the cannabis sativa in the medical industry. 2, selection of seedling time: selecting female hemp of the same product for female flower seed production, and starting seedling culture in early spring; thirdly, the induced plants are independently planted, and the induced plants are transferred into an isolation greenhouse to be independently cultivated after seedling raising. 4, greenhouse shading facilities are installed, wherein shading films are installed in the greenhouse, and closed space is formed after the shading films are started. 5, management of the induction plants: transplanting the induction plants to independent greenhouses in batches when the seedling age of the induction plants is 35 days. 6, managing pollinated plants: growing seedlings of the pollinated plants 14 days later than those of the induced plants, and transplanting the seedlings to a land greenhouse after the seedling age is 35 days. And 7, pollinating: placing the induced pollen plants by stages. According to the method disclosed by the invention, the seed yield is greatly improved in an open space on the premise of ensuring the female rate. The method is an efficient and practical cultivation technical measure.

Description

technical field [0001] The invention relates to a method for effectively increasing the yield of medicinal industrial hemp feminized seeds. Background technique [0002] Cannabis, Cannabis genus Cannabis is an annual herb. Industrial hemp refers to cannabis varieties that contain less than 0.3% tetrahydrocannabinol (THC). The total output value of industrial hemp in my country is about 7.5 billion yuan, of which textile fibers account for 76%, food accounts for 7%, and medicinal uses account for only 5%. Cannabidiol (CBD) is one of the main chemical components in medicinal industrial hemp. According to Boston Consulting Group (BCG), China's health food market is currently worth about 200 billion yuan. The market is projected to grow 10% annually through 2025. China is also the world's largest producer of pharmaceutical raw materials and the second largest pharmaceutical market in the world. CBD products present a diversified development, perfectly adapting to the update...
