Soilless culture matrix

Abstract

The invention provides a soilless culture matrix using coconut dusts as the main components; the soilless culture matrix can better simulate soil environment, can reduce fertilizer application amount, and can control insect diseases, thus further improving crop yield; the matrix comprises the following content: the soilless culture matrix comprises coconut dusts, and the coconut dusts are applied after being washed and desalted, wherein the EC value is smaller than 0.5mS / cm. The matrix uses coconut dusts as the main components of the matrix, thus artificially building the excellent rhizosphere environment replacing a soil environment and suitable for crop growth, and fully satisfying crop needs on mineral nutrition, moisture and gas environment conditions; the coconut dusts are washed and desalted so as to have the EC value smaller than 0.5S / cm, and applied, thus fully utilizing coconut dusts self special substance components, effectively promoting crop self nutrient composition accumulation, and further obtaining high-quality cultivation usage effect when compared with existing technology.

Description

technical field

[0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a soilless cultivation substrate. Background technique

[0002] Soilless cultivation uses peat or forest leaf humus, vermiculite and other light materials as the seedling substrate to fix the plants, allowing the plant roots to directly contact the nutrient solution, and adopts the modern seedling technology of mechanized precision seeding for one-time seedling formation. The selected seedling tray is divided into compartments, sow one seed in one compartment, and one plant in one room for seedlings. The root system of the seedlings and the substrate are intertwined with each other. nursery. Substrate cultivation is a method with the largest promotion area in soilless cultivation. It fixes the root system of the crop in an organic or inorganic substrate, and supplies the crop nutrient solution through drip irrigation or trickle irrigation. The cultivat...

Examples

Embodiment 1

[0015] Without loss of generality, the present invention provides a soilless cultivation substrate, the composition of the soilless cultivation substrate includes coconut peat; the coconut peat needs to be washed with water until the EC value is less than 0.5mS / cm before use. The invention adopts coconut peat as the main component of crop soilless culture substrate, artificially creates a good rhizosphere environment that can replace the soil environment and is suitable for crop growth, and fully meets the needs of crops for mineral nutrition, water, gas and other environmental conditions. Furthermore, because coconut peat is made of pure natural coconut fiber, the pH value is between 5.5-6.5, and microorganisms are not easy to breed, and it does not contain nematode bacteria, and it also has the natural advantage of inhibiting the reproduction of bacteria, which is conducive to promoting the healthy growth of crops Provide strong technical support. In addition, due to the uni...

Embodiment 2

[0017] This embodiment is on the basis of embodiment 1, and the content of coconut peat in the described soilless culture substrate is not less than 50%. In the present invention, the content of coir peat in the soilless culture substrate is further limited to not less than 50%, and on the basis of ensuring the basic nutrients required for crop growth, by mixing other ingredients into the substrate, it can further obtain suitable for cultivating different types of Technical effects of crops.

[0018] Preferably, in a preferred technical solution of this embodiment, the soilless culture medium further includes: soil.

Embodiment 3

[0020] The present invention is on the basis of embodiment 2, and described coconut peat is the coconut peat after sterilizing treatment with bactericide. The present invention effectively removes residual bacteria and insect eggs located in the coconut peat through the above technical means, and then provides strong technical support for promoting the growth of grapes.

[0021] Preferably, in a preferred technical solution of this embodiment, the soilless culture substrate further includes: at least one of grass-root soil and oily soil. It should be noted that the oily residue mentioned in the present invention refers to the remaining residue produced during the refining of edible vegetable oil.

[0022] Preferably, in a preferred technical solution of this embodiment, the soilless cultivation substrate is coconut peat. Experiments have shown that simply using coconut peat as the cultivation substrate of crop soilless cultivation can obtain the technical effect of cultivatin...
