Embodiment 1

[0052] Embodiment 1 A dwarfing and high-yielding planting method of medicinal marijuana, comprising the following steps:

[0053] A dwarfing and high-yield planting method for medicinal marijuana, comprising the following steps:

[0054] 1. Preparation before planting

[0055] Clean up the land in the greenhouse, dig a planting ditch with a width of 60 cm and a depth of 50 cm to meet the needs of the hemp root system to germinate; fill the planting ditch with planting soil, the components of the planting soil are sandy loam and leached soil, the proportion The ratio is 1:1, PH6.8, the soil is loose and fertile, and the drainage is good, which is conducive to the emergence of neat seedlings and avoids rotten roots and dead seedlings of cannabis plants;

[0056] Apply base fertilizer in planting soil, described base fertilizer is potassium fulvate, 20kg per mu, accelerates crop growth, strengthens the ability of soil water and fertilizer retention;

[0057] Assemble the root c...

Embodiment 2

[0086] Embodiment 2 A dwarfing and high-yielding planting method of medicinal marijuana, comprising the following steps:

[0087] The difference between this embodiment and embodiment 1 is that the preparation steps before planting are different, and the rest of the steps are consistent with embodiment 1, specifically as follows:

[0088] The land in the greenhouse is cleaned up, and a planting ditch is dug with a width of 50 cm and a depth of 40 cm to meet the needs of the hemp root system to germinate; the planting soil is filled in the planting ditch, and the components of the planting soil are sandy loam and leached soil, the proportion The ratio is 2:1, pH5.8, the soil is loose and fertile, and the drainage is good, which is conducive to the emergence of neat seedlings and avoids rotten roots and dead seedlings of cannabis plants;

[0089] Apply base fertilizer in planting soil, described base fertilizer is potassium fulvic acid, 15kg per mu, accelerates crop growth, stre...

Embodiment 3

[0092] Embodiment 3 A dwarfing and high-yielding cultivation method of medicinal marijuana, comprising the following steps:

[0093] The difference between this embodiment and Example 1 is that the ultrasonic treatment steps of the seeds in the seedling cultivation and field planting steps are different, and all the other steps are consistent with Example 1, specifically as follows:

[0094] Select Yunma No. 1 as a cultivar, dry the hemp seeds for 2 hours, wash them with distilled water, and place the washed seeds in a mixed solution for ultrasonic treatment for 15 minutes to increase the germination rate of the seeds;

[0095] The mixed solution contains 0.03% boric acid, 0.05% zinc sulfate, 0.08% potassium permanganate, and the rest is distilled water. Treating seeds with the mixed solution can significantly increase the yield of cannabis flowers and leaves; the frequency of the ultrasonic treatment is 220KHZ .

[0096] Using high-performance liquid chromatography to detect...

Abstract

The invention provides a planting method for dwarfing and high-yield medicinal cannabis sativa. The planting method comprises the steps of preparation before field planting, field planting after seedling raising and management after field planting; management after field planting comprises a seedling growing period, a rapid growing period, synthesis promoting agent injection and a flowering period. Cannabis sativa seedlings are transplanted into a root control container for field planting, dwarfing and rational close planting of the cannabis sativa are achieved, the height of cannabis sativa plants is controlled to be 92-103 cm, the land space is saved, the photosynthetic area is effectively increased, the yield of floral leaves is increased, and the cultivation time is shortened; harvesting is easier after dwarfing, and the labor productivity is improved; when 3-4 pairs of true leaves grow on the cannabis sativa seedlings, cold treatment is carried out, at the moment, the seedlings mainly grow in a vegetative mode and do not grow in a reproductive mode, and the flower bud differentiation process is promoted to advance after cold treatment; a female inducing agent is sprayed to the cannabis sativa, so that the number of female flowers is greatly increased during sex differentiation of the cannabis sativa; a synthesis promoting agent is injected into the cannabis sativa, CBDA synthetase genes are increased, CBDA synthetase is increased, synthesis of CBD is promoted, and therefore the content of CBD is increased.

Description

technical field [0001] The invention belongs to the technical field of hemp cultivation, and in particular relates to a dwarf and high-yield cultivation method of medicinal hemp. Background technique [0002] Cannabis has extremely high medicinal value and has a long history of medicinal use. Its two main components are tetrahydrocannabinol (THC) and cannabidiol (CBD). There are three main types of marijuana, namely medical marijuana [tetrahydrocannabinol (THC) > 0.3%], medicinal marijuana [tetrahydrocannabinol (THC) < 0.3%, high content of cannabidiol (CBD)] and industrial hemp [ Tetrahydrocannabinol (THC) <0.3%, used to obtain fiber and seeds, low content of cannabidiol (CBD)], CBD has anti-inflammatory, bactericidal, analgesic, anti-anxiety, anti-oxidant and other effects, and also has therapeutic Potential medical value in conditions such as schizophrenia and Alzheimer's disease. With the exploration of the medicinal value of CBD, the cultivation and productio...
