Embodiment 1

[0017] Embodiment 1: the preparation of the medium provided by the present invention

[0018] The medium provided by the present invention consists of the following components in parts by volume:

[0019] Heliotrope, 38-42%; clinoptilolite, 16-21%; diatomaceous earth, 5-7%;

[0020] Akadama soil, 11-16%; Kanuma soil, 6-9%; Kiryu sand, 5-10%;

[0021] refer to figure 1 Its preparation process is as follows:

[0022] 1. According to the above ratio, take the raw material A hinata, the raw material B clinoptilolite, and the raw material C Kiryu sand;

[0023] 2. High-temperature and high-pressure treatment of raw materials A, B, and C: through a high-temperature and high-pressure reaction kettle, a double-cycle electric heating furnace is used to heat the kettle. Make the oil temperature in the kettle reach 550±10°C, pressurize to 200±10MPa and keep constant temperature and pressure for 2 to 3 hours, close the reaction kettle and let it cool down slowly until the temperatur...

Embodiment 2

[0029] Take 42L of heliotrope with a particle size of 3-5mm after the high-temperature and high-pressure treatment in step 2 of Example 1, 19L of clinoptilolite, and 10L of Kiryu sand, and mix the three samples evenly for later use. After sieving, the particle size is 2-6.5mm 16L of red jade soil, 5L of diatomaceous earth, and 8L of Kanuma soil, mixed with the aforementioned mixture of hinataite, clinoptilolite, and Kiryu sand, then removed impurities, polished, washed with water, and dried with hot air, and added 0.07g / m of lime nitrogen 2 And long-acting controlled-release fertilizer 3g / L to prepare a mixed medium, which is widely used in plant cultivation medium, characterized by cleanliness, no pests and weed seeds, green and environmental protection, and good fertilizer retention effect.

Embodiment 3

[0031] Take 42L of heliotrope with a particle size of 3-5mm after the high temperature and high pressure treatment in step 2 of Example 1, 21L of clinoptilolite, and 8L of Kiryu sand, and mix the three samples evenly for later use. After sieving, the particle size is 2-6.5mm 16L of red jade soil, 5L of diatomaceous earth, and 8L of Kanuma soil, mixed with the aforementioned mixture of hinataite, clinoptilolite, and Kiryu sand, then removed impurities, polished, washed with water, and dried with hot air, and added 0.07g / m of lime nitrogen 2 And long-acting controlled-release fertilizer 3g / L to make a mixed medium, which is widely used as a garden bottom stone. It is characterized by strong water holding capacity, good air permeability, and no waterlogging.

Abstract

The invention provides a cultivation medium, which comprises the following components in percentage by volume: 38 to 42 percent of Mako Hyuga stone, 16 to 21 percent of clinoptilolite, 5 to 7 percent of infusorial earth, 11 to 16 percent of red jade earth, 6 to 9 percent of allophone, 5 to 10 percent of Kiryu sand. In the invention, the Mako Hyuga stone, after high-temperature treatment, has the basic excellent properties of media, such as permeability, water discharge, insusceptibility to decomposition and breakage and high stability; and due to a chemical inertness, the Mako Hyuga stone can prevent the increase of surface adsorbates of the clinoptilolite exposed in the air for an overlong time and can prolong the service life of the clinoptilolite by 3 to 5 years effectively.

Description

technical field [0001] The invention relates to a cultivation medium. Background technique [0002] Plant growth media are broadly divided into three categories according to their sources: natural soils, modified soils with conditioners added, and soilless culture substrates. Soilless culture substrates generally refer to the preparation of natural minerals, industrial and agricultural organic and inorganic wastes or mixed / composites. Compared with the first two types of soil cultivation, the soilless cultivation substrate not only has the fertility characteristics of water, fertilizer, air, heat, etc. similar to natural soil for plant growth, but also can adjust the physical and chemical properties according to the needs of different plant production. Water, save fertilizer, avoid soil pollution and other advantages. [0003] At present, soilless cultivation substrates can be divided into two categories: organic media and inorganic media according to their composition. Co...
