Embodiment 1

[0021] In this embodiment, the weight ratio of tourmaline, medical stone, zeolite, vermiculite, perlite, diatomaceous earth, reed powder and attapulgite is 6:13:9:5:4:10:35:18. Prepare as follows:

[0022] (1) Stir tourmaline, medical stone, zeolite, vermiculite, perlite and diatomaceous earth evenly;

[0023] (2) adding reed powder into the mixed powder of step (1), stirring evenly;

[0024] (3) adding the binder to the mixture obtained in step (2), adding an appropriate amount of water for stirring, and putting the raw materials into a mold through a twin-screw extruder for extrusion molding;

[0025] (4) Microwave sterilize the raw materials compressed and formed in step (3) together with the mold for 15 minutes to play a biological sterilization effect on the powdered reeds, and then keep warm at 100-200°C in an oven for 40 minutes.

Embodiment 2

[0027] In this embodiment, the weight ratio of tourmaline, medical stone, zeolite, vermiculite, perlite, diatomaceous earth, reed powder, and attapulgite is 8:9:11:7:5:6:34:20. Prepare as follows:

[0028] (1) Stir tourmaline, medical stone, zeolite, vermiculite, perlite and diatomaceous earth evenly,

[0029] (2) adding reed powder into the mixed powder of step (1), stirring evenly;

[0030] (3) Add the binder to the mixture obtained in step (2), add an appropriate amount of water and stir, put the raw materials into a mold through a twin-screw extruder and extrude them.

[0031] (4) Microwave sterilize the raw materials compressed and formed in step (3) together with the mold for 15 minutes to play a biological sterilization effect on the powdered reeds, and then keep warm at 100-200°C in an oven for 40 minutes.

Embodiment 3

[0033] In this embodiment, the weight ratio of tourmaline, medical stone, zeolite, vermiculite, perlite, diatomaceous earth, reed powder and attapulgite is 9:12:10:6:13:32:19. Prepare as follows:

[0034] (1) Stir tourmaline, medical stone, zeolite, vermiculite, perlite and diatomaceous earth evenly,

[0035] (2) adding reed powder into the mixed powder of step (1), stirring evenly;

[0036] (3) Add the binder to the mixture obtained in step (2), add an appropriate amount of water and stir, put the raw materials into a mold through a twin-screw extruder and extrude them.

[0037] (4) Microwave sterilize the raw materials compressed and formed in step (3) together with the mold for 15 minutes to play a biological sterilization effect on the powdered reeds, and then keep warm at 100-200°C in an oven for 40 minutes.

Abstract

The invention relates to a soilless culture substrate for original plants capable of prompting growth of plants and a preparation method thereof. The soilless culture substrate comprises the following ingredients such as 3-10% parts by weight of tourmaline, 7-18% parts by weight of syrup, 9-18% of zeolite, 2-8% parts by weight of vermiculite, 3-7% parts by weight of perlite, 4-16% parts by weight of diatomaceous earth, 30-50% parts by weight of agroforestry waste, and 12-21% parts by weight of binders. The sum of the weight ratios of the components above is 100%. The method comprises the following steps: uniformly mixing tourmaline, medical stones, zeolite, vermiculite, perlite, diatomite powder; adding agricultural and forestry wastes, binders and mixed powder for uniform mixing; extruding them into formation through a double screw-rod extruder and disinfecting the mixture by microwaves. The soilless culture substrate for original plants capable of prompting growth of plants and the preparation method thereof have the features: the soilless culture substrate is low in weight, good in air breathability and water absorption, high in water retention and capable of promoting the growth of plants.

Description

technical field [0001] This field belongs to the field of soilless cultivation of plants, and specifically relates to an original ecological plant cultivation substrate for promoting plant growth and a preparation method thereof. [0002] technical background [0003] Soilless cultivation mainly includes hydroponics, aeroponics and substrate cultivation, among which substrate cultivation is the most important form of soilless cultivation. Affected by factors such as application cost, practicability, and difficulty in operation and management, more than 90% of the commercial soilless home delivery in the world currently adopts the substrate cultivation method. The main function of soilless cultivation substrate is to support and fix plants, and provide a stable and coordinated water, air and fertilizer environment for plant roots. In addition to supporting and fixing plants, it more importantly acts as a "transfer station", allowing nutrients and water from the nutrient solut...
