Embodiment 1

[0035] (1) In the nursery room, prepare shelves with a height of about 70 cm, which can be installed in multiple layers, and install fluorescent tubes on each layer. Keep the space humidity at 60%; the temperature at 22°C, and the light at 55μmol / (m 2 s).

[0036] Clean the cutting box with 500ppm sodium hypochlorite and dry it for later use.

[0037] The rock wool block is soaked in RO water with a pH of 5.5 for 5 minutes, and the water is controlled for 1 minute; it is soaked in a nutrient solution with a pH of 5.7 (the mass ratio of nitrogen, phosphorus and potassium is 12:8:9) for 5 minutes, and the water is controlled for 1 minute.

[0038] (2) Select robust single-bud twigs with a cutting length of 15 m and a thickness greater than or equal to 2.0 mm; trim the leaves and keep the cuttings with three pairs of true leaves.

[0039] Use a blade to cut the cuttings into a length of 13 cm, with a 45-degree slope at the end, and draw a line at the end, soak the cut cuttings ...

Abstract

The invention provides a method for growing cannabis indoor cutting seedlings. The method at least includes the following steps: (1) substrate treatment: soak rock wool blocks in water with a pH of 5.0 to 5.7; then use nitrogen and phosphorus with a pH of 5.7 to 6.0 Soak in potassium compound nutrient solution; (2) Cutting: Soak hemp cuttings in rooting agent, insert rock wool block, the humidity is 60%-65%; the temperature is 22-24°C, and the light intensity is 55-65μmol / ( m 2 s), indoor seedling cultivation under the condition that the luminous flux density ratio of red light and blue light is 0.55:1-0.63:1; (3) Management: Spray amino acid foliar fertilizer twice a day, and the concentration of foliar fertilizer is 0.05%-0.1% ; Supplement the water and nutrition in the matrix. Adopting this method to cultivate marijuana shortens the seedling time, and the cuttings begin to take root after one week, and all can take root in two weeks to achieve the purpose of seedling cultivation; the survival rate of seedlings is high, which can reach 100%; the plants are all green during the seedling cultivation process; at the same time, it is faster than soilless The traditional method greatly reduces the consumption of nutrient solution.

Description

technical field [0001] The invention relates to a method for growing cannabis seedlings by cutting indoors. Background technique [0002] Cannabis sativa belongs to the genus Cannabis of the family Cannabinaceae. It is an annual herb, mostly dioecious. It is cultivated all over the world, and now it is mainly distributed in Asia and Europe. Cannabis has important economic value, and it can be used in many aspects such as textiles, food, medicine, building materials and papermaking; more and more studies have proved that cannabinoids still have It has a wide range of pharmacological effects and is widely used in the treatment of chronic diseases, with a large market demand. [0003] The reproduction of industrial hemp is an important part of the cultivation technology. The widely used reproduction methods in production are sexual reproduction and asexual reproduction. Among them, the growth cycle of seed reproduction is long and the plants are prone to diseases at the seedl...
