Embodiment 1

[0028] This embodiment relates to a preparation method of fermented Jerusalem artichoke stalks, comprising the following steps:

[0029] 1) Crush the air-dried Jerusalem artichoke stalks to 3-6 cm with a feeder for livestock, and stack them layer by layer according to the thickness of 15 cm. For each layer of straw, evenly pour the conditioning solution mixed with the starter to adjust the Jerusalem artichoke stalks. The water content of the straw heap is 50%, the C / N is 25:1, the total height to the said Jerusalem artichoke straw heap is 1.0m, and the surface is covered with a plastic film to obtain a heap of Jerusalem artichoke straw to be fermented;

[0030]2) Stack and ferment for 45 days. During the fermentation period, the water content is kept at 50% by replenishing water, and the pile is turned 2 to 3 times depending on the temperature and humidity.

[0031] The starter is an organic waste fermentation koji, and its addition amount is 0.4% of the total mass of the drie...

Embodiment 2

[0035] This embodiment relates to a preparation method of fermented Jerusalem artichoke stalks, comprising the following steps:

[0036] 1) Pulverize the Jerusalem artichoke straw to 3-6 cm with a feeder for livestock, and stack it layer by layer according to the thickness of 20 cm. For each layer of straw, evenly pour the conditioning solution mixed with the starter to adjust the density of the Jerusalem artichoke straw pile. The water content is 60%, the C / N is 35:1, the total height to the pile of Jerusalem artichoke straw is 1.2m, and the surface is covered with a plastic film to obtain a pile of Jerusalem artichoke straw to be fermented;

[0037] 2) Stack and ferment for 50 days. During the fermentation period, the moisture content is kept at 60% by replenishing water, and the pile is turned 2 to 3 times depending on the temperature and humidity.

[0038] The starter is an organic waste fermentation koji, and its addition amount is 0.5% of the total mass of the dried arti...

Embodiment 3

[0042] This embodiment relates to a preparation method of fermented Jerusalem artichoke stalks, comprising the following steps:

[0043] 1) Pulverize the Jerusalem artichoke straw to 3-6 cm with a feeder for livestock, and stack it layer by layer according to the thickness of 20 cm. For each layer of straw, evenly pour the conditioning solution mixed with the starter to adjust the density of the Jerusalem artichoke straw pile. The water content is 55%, the C / N is 30:1, the total height to the pile of Jerusalem artichoke straw is 1.0-1.2m, and the surface is covered with a plastic film to obtain a pile of Jerusalem artichoke straw to be fermented;

[0044] 2) Stack and ferment for 50 days. During the fermentation period, the moisture content is kept at 55% by replenishing water, and the pile is turned 2 to 3 times depending on the temperature and humidity.

[0045] The starter is an organic waste fermentation koji, and its addition amount is 0.5% of the total mass of the dried ...

Abstract

The invention relates to a fermented jerusalem artichoke straw for soilless culture, and the fermentative jerusalem artichoke straw is prepared through the following method, wherein the method comprises the steps: 1), carrying out the natural withering of the jerusalem artichoke straw, smashing the jerusalem artichoke straw till the length is from 3 cm to 6 cm, stacking the smashed jerusalem artichoke straws, uniformly adding adjustment liquid with a leavening agent to the jerusalem artichoke straw stack, adjusting the content of water in the jerusalem artichoke straw stack to 50%-60%, and obtaining an to-be-fermented, wherein C / N is 25-35:1; 2), carrying out the fermentation of the to-be-fermented jerusalem artichoke straw stack for 45-50 days under the room temperature, and obtaining the fermented jerusalem artichoke straw. According to the invention, the fermented jerusalem artichoke straw cooperates with turf and vermiculite, thereby obtaining a soilless culture medium with the void ratio being more beneficial for the growth of vegetables, bringing a good root environment for the growth of roots. Moreover, compared with a composite medium which just contains turf and vermiculite, the medium can improve the health of vegetable seedlings, improves the anti-disease capability of the vegetable seedlings, and improving the yield.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation substrates, in particular to a composite cultivation substrate added with fermented artichoke stalks. Background technique [0002] my country is a major producer of facility agriculture. From the perspective of area and output, China's facility agriculture ranks among the top in the world (Zhang Zhen et al., 2015; Zhao Cuiying et al., 2015). However, during the development of facility agriculture in my country, management methods such as flooding and fertilization have emerged, which have led to shortcomings in facility agriculture soil cultivation such as continuous cropping obstacles, soil secondary salinization, unbalanced nutrient supply and demand, and difficult control of diseases and insect pests (Tian Jilin ; hairiness). Soilless cultivation is an advanced technology widely used in protected agriculture in the world. It has many advantages such as avoiding soil-borne diseases...
