Problems solved by technology

However, the existing industrial hemp breeding is mostly seed direct seeding or seedling seedling transplanting, which cannot meet the specific gender requirements expected in production. Cutting seedling breeding is an asexual reproduction technology, which can quickly and batch obtain high-quality, gender-consistent industrial hemp The method of planting seedlings
[0004] Traditionally, during the hydroponic growth of industrial hemp cuttings, in order to prevent rotten and dead roots and increase the rooting rate of cuttings, some chemical agents or hormones are often used as rooting accelerators, which cannot meet environmental protection requirements
The Chinese patent application with the application number 201911419958.3 discloses a green and environmentally friendly method for hydroponic rooting of cuttings of medicinal industrial hemp, but this method requires the use of a complicated and special hydroponic device

Embodiment 1

[0024] The method for promoting the hydroponic rooting of industrial hemp cutting seedlings of the present embodiment comprises the following steps:

[0025] Step 1. Select semi-lignified industrial hemp cuttings that grow robustly and are free from diseases and insect pests, cut the cuttings into 8cm branches, and cut off the excess leaves at the bottom, leaving only the top 4 leaves;

[0026] Step 2. Fix the cut cutting seedlings with a planting sponge, and the fixed part is the base part 5 cm away from the bottom cut of the cutting seedlings;

[0027] Step 3. Put the open-celled foam sheet in a container filled with tap water, put a submersible pump in the container, and the submersible pump is turned on during the whole process of hydroponic rooting, and the water level of the tap water is 10cm from the bottom of the container;

[0028] Step 4. Insert the fixed cutting seedlings into the holes of the foam sheet, and immerse the bottom of the cutting seedlings in tap water ...

Abstract

The invention discloses a method for promoting hydroponic rooting of industrial hemp cutting seedlings. According to the method, after semi-lignified industrial hemp cutting seedlings are cut, the cutting seedlings are not soaked in a plant growth regulator, the cutting seedlings are directly fixed in a container containing tap water through a foam thin plate, then a magnetic graphene oxide nano-composite with a certain concentration is added into the container, and rapid hydroponic rooting of the industrial hemp cutting seedlings is promoted. The method is easy to operate, infection of harmful bacteria on plant cutting seedlings can be effectively inhibited while rooting of the industrial hemp cutting seedlings is promoted, the cut portions of the industrial hemp cutting seedlings treated through the method can expand to generate calluses within 5-6 days, rooting can be achieved within 7-10 days, the rooting rate can reach 70% or above, and the rooting rate can reach 100% within 12-15 days.

Description

technical field [0001] The invention relates to the technical field of cutting propagation of industrial hemp, in particular to a method for promoting rooting of cutting seedlings of industrial hemp through hydroponics. Background technique [0002] Cannabis sativa L. is an annual herb belonging to the genus Cannabis in the family Cannabinaceae. Industrial hemp refers to varieties of cannabis that contain less than 0.3% tetrahydrocannabinol (THC). Industrial hemp has high economic value, and its fiber type and oil (seed) type have been widely used in fields such as textiles, food, bioengineering materials, and papermaking. In recent years, the medicinal type for the purpose of extracting flowers and leaves has gradually become a new direction for the development of the industrial hemp industry because it contains cannabinoids such as cannabidiol (CBD), which is a medicinal ingredient. [0003] Most industrial hemp is dioecious. If the purpose of production is to harvest fi...
