specific Embodiment approach 1

[0009] Specific embodiment one: the medicinal industrial hemp plug seedling cultivation matrix of the present embodiment is made up of 70%-80% peat soil, 5%-10% vermiculite, 5%-10% perlite and 8%-10% by volume Composed of coconut bran; the above raw materials are mixed and stirred, put into the hole tray, and the surface of the hole tray is paved, watered, so that the water completely soaks the substrate, and then sprayed with 1000 times of 25% carbendazim wettable powder to obtain the pharmaceutical industry Hemp plug seedling substrate.

[0010] The main function of peat soil in this embodiment is to provide the organic matter needed for seedling growth; vermiculite is mainly used to increase the air permeability of the substrate; perlite increases the water and fertilizer retention capacity of the substrate; coconut peat prevents the root system of plants from corroding and promotes the growth of plant roots .

specific Embodiment approach 2

[0011] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that the bulk density of the medicinal industrial hemp plug seedling substrate is 0.4-0.8g / cm 3 . Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0012] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the total porosity of the medicinal industrial hemp seedling growth matrix is ​​70-80%. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a medicinal industrial hemp plug seedling substrate. The invention belongs to the technical field of medicinal industrial hemp planting, and particularly relates to the medicinal industrial hemp plug seedling substrate. The method aims at solving the problems that in the existing medicinal industrial hemp planting process, the seed emergence rate is low, the apical dominance is serious, and the later growth and development of plants are seriously affected. The medicinal industrial hemp plug seedling substrate is prepared from the following components in percentage by volume, 70%-80% of peat soil, 5%-10% of vermiculite, 5%-10% of perlite and 8%-10% of coco coir. The raw materials are uniformly mixed and stirred, a mixture is put into a plug tray, the surface of the plug tray is flattened and watered, the substance is completely soaked in water, then 1000-fold liquid of 25% carbendazim wettable powder is sprayed, and the medicinal industrial hemp plug seedling substrate is obtained. The medicinal industrial hemp plug seedling substrate is used for planting medicinal industrial hemp.

Description

technical field [0001] The invention belongs to the technical field of medicinal industrial hemp planting, and in particular relates to a seedling-raising substrate for medicinal industrial hemp plugs. Background technique [0002] Industrial hemp refers to cannabis that is legally planted and has a tetrahydrocannabinol (THC) content of less than 0.3%. According to international standards, cannabis with a 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 this basis, the concept of medical industrial hemp is defined, that is, the THC content <0.3%, and the industrial hemp with high content of cannabidiol (CBD) is called medicinal industrial hemp (Li Qiushi, Meng Ying, Chen Shilin. Medicinal cannabis species Quality resource classification and research strategy. Chinese Journal of Traditional Chinese Medicine, 2019, 44(20):4309-4316). Among them, CBD is a non-psychoactive co...
