Embodiment 1

[0030] An organic substrate for soilless cultivation for capsicum seedlings, the substrate is to mix the fermented corn cob fragments, corn stalk fragments and rice husks in a volume ratio of 3:3:2, and then press the mixture The total volume after homogenization is added to 10kg / m 3 puffed chicken manure.

[0031] Specifically adopt the following method to prepare:

[0032] 1) Crush the corn stalks and corncobs into fragments with a particle size of 0.5cm to 1.5cm for later use;

[0033] 2) Adjust the C / N of the fermentation substrate to make the nutritional balance after the material is finished

[0034] The carbon-to-nitrogen ratio of the matrix raw materials is determined in a routine laboratory, specifically: C / N=76:1 for corn stalks, C / N=82:1 for corncobs, and C / N=112:1 for rice husks;

[0035] Calculate and adjust the C / N to 20:1 according to the actual C / N of each substrate measured before substrate fermentation. The required urea amounts are 6.13 g of urea per kg o...

Embodiment 2

[0044] An organic substrate for soilless cultivation for capsicum seedlings, the substrate is to mix the fermented corn cob fragments, corn stalk fragments and rice husks in a volume ratio of 3.5:4:3, and then press the mixture The total volume after homogenization is added to 12kg / m 3 puffed chicken manure.

[0045] Specifically adopt the following method to prepare:

[0046] 1) Crush the corn stalks and corncobs into fragments with a particle size of 0.5cm to 1.5cm for later use;

[0047] 2) Adjust the C / N of the fermentation substrate to make the nutritional balance after the material is finished

[0048] The carbon-to-nitrogen ratio of the matrix raw materials is measured in a routine laboratory, specifically: C / N=80:1 for corn stalks, C / N=85:1 for corncobs, and C / N=108:1 for rice husks;

[0049] 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...

Embodiment 3

[0058] An organic substrate for soilless culture for capsicum seedlings, the substrate is to mix the fermented corn cob fragments, corn stalk fragments and rice husks in a volume ratio of 4:5:4, and then press the mixture The total volume after homogenization is added to 15kg / m 3 puffed chicken manure.

[0059] Specifically adopt the following method to prepare:

[0060] 1) Crush the corn stalks and corncobs into fragments with a particle size of 0.5cm to 1.5cm for later use;

[0061] 2) Adjust the C / N of the fermentation substrate to make the nutritional balance after the material is finished

[0062] 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 rice husks;

[0063] Calculate and adjust the C / N to 30:1 according to the actual C / N of each substrate measured before substrate fermentation. The required urea amounts are 3.48 g of urea per kg of co...

Abstract

The invention discloses a soilless cultivation organic substrate and a preparation method thereof. The preparation method comprises the following steps: respectively mixing the broken blocks of maize cobs, the broken blocks of maize stalks and rice hulls evenly after being stacked and fermented in the volume ratio of 3-4:3-5:2-4 and then adding 10-15kg / m3 of puffed chicken dung according to the total volume after being mixed evenly. The soilless cultivation organic substrate provided by the invention adopts the main raw materials of the maize stalks, the maize cobs and the rice hulls which are discarded in the local agricultural production so as to replace the substrate raw material of grass carbon which is commonly used in seedling raising at present, which not only can save the seedling raising cost greatly but also reduces the overexploitation of the unrenewable resource of the grass carbon and maintains the sustainable development of ecology; on the other hand, by utilizing the agricultural wastes reasonably, the income of local farmers is increased, and the wastage of resources is reduced.

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 capsicum 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 on...
