Embodiment 1

[0027] The invention relates to an organic substrate for soilless cultivation for tomato seedling cultivation. The substrate is obtained by mixing the fermented corn cob fragments, corn stalk fragments and mushroom dregs in a volume ratio of 1.5:4:1.5.

[0028] Specifically adopt the following method to prepare:

[0029] 1) Crush the corn stalks and corncobs into fragments with a particle size of 1 cm to 3 cm for later use;

[0030] 2) Adjust the C / N of the fermentation substrate to make the nutritional balance after the material is finished

[0031] The carbon-to-nitrogen ratio of the matrix raw materials is measured in a routine laboratory, specifically: C / N=76:1 for corn stalks, C / N=82:1 for corn cobs;

[0032] According to the actual C / N of each substrate measured before substrate fermentation, the amount of urea required to adjust the C / N to 20:1 is calculated as 6.13g of urea per kilogram of corn stalk, 6.79g of urea per kilogram of corncob, and a small amount of urea. ...

Embodiment 2

[0040] The invention relates to an organic substrate for soilless cultivation for tomato seedling cultivation. The substrate is obtained by mixing the fermented corn cob fragments, corn stalk fragments and mushroom dregs in a volume ratio of 2:5:3.

[0041] Specifically adopt the following method to prepare:

[0042] 1) Crush the corn stalks and corncobs into fragments with a particle size of 1 cm to 3 cm for later use;

[0043] 2) Adjust the C / N of the fermentation substrate to make the nutritional balance after the material is finished

[0044] The carbon-to-nitrogen ratio of the matrix raw materials is determined in a routine laboratory, specifically: C / N=80:1 for corn stalks, C / N=85:1 for corncobs, and C / N=108:1 for mushroom dregs;

[0045] According to the actual C / N of each substrate measured before substrate fermentation, the amount of urea needed to adjust the C / N to 25:1 is calculated as 4.8 g of urea per kilogram of corn stalk, 5.23 g of urea per kilogram of corncob...

Embodiment 3

[0053] The invention discloses an organic substrate for soilless cultivation for tomato seedling cultivation. The substrate is obtained by mixing the fermented corn cob fragments, corn stalk fragments and mushroom dregs in a volume ratio of 2.5:6:4.5.

[0054] Specifically adopt the following method to prepare:

[0055] 1) Crush the corn stalks and corncobs into fragments with a particle size of 1 cm to 3 cm for later use;

[0056] 2) Adjust the C / N of the fermentation substrate to make the nutritional balance after the material is finished

[0057] The carbon-to-nitrogen ratio of the matrix raw materials is determined in a routine laboratory, specifically: C / N=78:1 for corn stalks, C / N=82:1 for corncobs, and C / N=118:1 for mushroom dregs;

[0058] According to the actual C / N of each substrate measured before substrate fermentation, the amount of urea needed to adjust the C / N to 25:1 was 4.8 g of urea per kilogram of corn stalk, 5.23 g of urea per kilogram of corn cob, and 5.2...

Abstract

The invention discloses a soilless culture organic matrix and preparation method thereof; wherein the soilless culture organic matrix is formed by evenly mixing corn cob fragments, corn stalk fragments and mushroom residue after respective piling fermentation according to volume ratio of (1.5-2.5): (4-6): (1.5-4.5). The main raw materials of the soilless culture organic matrix provided by the invention adopts waste corn stalk, corn cob and mushroom residue in local agricultural production instead of matrix raw material grass carbon commonly used in the current seedling raising, thus not only greatly saving seedling raising cost but also reducing over-exploitation of non-renewable resources grass carbon, thereby maintaining ecological sustainable development; not only environmental pollution caused by burning is avoided, but also sustainable utilization of resources is realized.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and relates to a soilless cultivation organic substrate and a preparation method thereof, in particular to a soilless cultivation organic substrate for tomato seedling cultivation and a preparation method thereof. Background technique [0002] Soilless cultivation originated in the 17th century is a new type of cultivation. Soilless cultivation can better increase the yield of crops, and can better control the growth and nutrient supply of plants. According to the provisions of the Society for Soilless Cultivation, those who do not use natural soil, use substrates or not, use nutrient solution to irrigate plant roots or have other methods are soilless cultivation. [0003] Plug seedling cultivation is a modern method of raising seedlings by using plug trays as seedling containers, using light substrates such as peat, vermiculite, and perlite as seedling substrates, one hole and one ...
