Example Embodiment

[0015] 1. Raw material selection

[0016] Perlite is mainly composed of silica with crystal water. In the process of mineralization, other minerals are immersed in the ore, which contains mineral components of calcium, iron, magnesium, sulfur, phosphorus, potassium and sodium in addition to silicon.

[0017] In the raw material selection process, first analyze the mineral content of the perlite ore, and select the ore with high soluble mineral content as the raw material, which is calculated by mass percentage. Among them, by mass percentage, silica 70-78%, oxidation Radium 2-3%, iron oxide 0.5-1%, ferrous oxide 0.5-1%, calcium oxide 0.5-2%, potassium oxide 0.5-1.5%, phosphorus pentoxide 3-5% of perlite ore as perlite Ore raw materials.

[0018] 2. Crushed raw materials

[0019] The selected perlite ore raw materials are crushed to produce ore perlite powder with a particle diameter of 0.1-0.2mm.

[0020] 3. Raw material Penghua

[0021] The prepared ore perlite powder is added to an e...

Abstract

The invention discloses an expanded perlite plant cultivation media, which is produced through the steps of selection of raw materials 1, crushing of raw materials 2, expansion of raw materials 3, preparation of nutrient solution 4, soaking treatment of the nutrient solution 5, drying 6 and formation of finished products 7. In the invention, the expanded perlite plant cultivation media is used as a seedling-raising cultivation medium and has the characteristics of favorable air permeability, favorable fertility and mound, paddy cultivation of seedling is carried out by using the expanded perlite plant growing media so as to rapidly sprout seeds and spread roots with densely green plants and numerous roots, shorten the periods of growing the seelding and have more dry substances, therefore, the expanded perlite plant growing media can be used as the paddy grow cultivation media and also can be applied to seedling-raising and cultivation of other plants.

Description

technical field [0001] The invention proposes an expanded perlite plant cultivation substrate used for seedling cultivation in the agricultural field. Background technique [0002] Before the present invention was proposed, expanded perlite was used instead of soil as the substrate for plant cultivation. Because perlite is a mineral and has a porous structure, it has good air permeability and is conducive to the development and growth of plant roots, so that the cultivated plant roots are developed, with strong water and fertilizer absorption capabilities, and at the same time promote the growth and development of plants. , increase the accumulation of dry matter, and increase the output rate. [0003] However, the nutritional content of the currently used expanded perlite cannot be controlled, and its particles are usually the size of particles used in thermal insulation materials. The particle diameter is between 2-5mm, and those smaller than 2mm are not used. Therefore,...
