Embodiment 1

[0040] (1) Vegetable straw and anaerobic fermentation agent (8 parts of Bacillus subtilis, 8 parts of straw decomposing bacteria, and 5 parts of cellulase) were mixed according to the mass ratio of 100:1, and then sealed and fermented. The fermentation temperature was 40°C and the fermentation time was 7 One day, an anaerobic fermentation product was obtained.

[0041] (2) After the primary anaerobic fermentation product is stirred and mixed, it is mixed with the EM microbial agent at a mass ratio of 100:3, and then the water content is adjusted to 60%, and the secondary aerobic fermentation is carried out at 200rpm and 40°C for 10 days to obtain Secondary aerobic fermentation product.

[0042] (3) After adjusting the water content of the secondary aerobic fermentation product to 80%, the microwave power is 300W, the ultrasonic frequency is 40K Hz, and the microwave ultrasonic is heated to 35°C for 2 hours, then left to settle, and the supernatant is obtained by solid-liquid sep...

Embodiment 2

[0044] (1) Vegetable straw and anaerobic fermentation agent (5 parts of Bacillus subtilis, 10 parts of straw decomposing bacteria, and 3 parts of cellulase) were mixed according to the mass ratio of 100:3 and then sealed and fermented at a fermentation temperature of 45°C and a fermentation time of 5 One day, an anaerobic fermentation product was obtained.

[0045] (2) After the primary anaerobic fermentation product is stirred and mixed, it is mixed with the EM bacterial agent at a mass ratio of 100:1, and then the water content is adjusted to 60%, and the secondary aerobic fermentation is carried out at 200rpm and 30°C for 7 days to obtain Secondary aerobic fermentation product.

[0046] (3) After adjusting the water content of the secondary aerobic fermentation product to 90%, the microwave power is 500W, the ultrasonic frequency is 20K Hz, and the microwave ultrasonic treatment is heated to 50°C for 1 hour, and then the supernatant is obtained by solid-liquid separation. ...

Embodiment 3

[0048] (1) Vegetable straw and anaerobic fermentation agent (10 parts of Bacillus subtilis, 5 parts of straw decomposing bacteria, and 5 parts of cellulase) were mixed according to the mass ratio of 100:3 and then sealed and fermented at a fermentation temperature of 45°C and a fermentation time of 5 One day, an anaerobic fermentation product was obtained.

[0049] (2) After the primary anaerobic fermentation product is stirred and mixed, it is mixed with the EM bacterial agent at a mass ratio of 100:1, and then the water content is adjusted to 60%, and the secondary aerobic fermentation is carried out at 300rpm and 45°C for 7 days to obtain Secondary aerobic fermentation product.

[0050] (3) After adjusting the water content of the secondary aerobic fermentation product to 90%, the microwave power is 300W, the ultrasonic frequency is 40K Hz, and the microwave ultrasonic treatment is heated to 30°C for 2 hours, and then the supernatant is obtained by solid-liquid separation. ...

Abstract

The invention relates to the technical field of Chinese flowering cabbage planting, in particular to a preparation method of a nutrient solution for improving the quality of Chinese flowering cabbages as well as a product and application thereof. The method comprises the following steps: performing primary anaerobic fermentation on vegetable straws to obtain a primary fermentation product; performing secondary aerobic fermentation on the primary fermentation product to obtain a secondary fermentation product; and carrying out microwave ultrasonic treatment on the secondary fermentation product, standing and precipitating, and carrying out solid-liquid separation to obtain a supernatant which is the nutrient solution for improving the quality of the Chinese flowering cabbage. According to the method, the vegetable straw is used as the raw material, and the nutrient solution for improving the quality of the Chinese flowering cabbage is prepared through secondary aerobic fermentation after sealed fermentation, so that recycling of the vegetable straw is achieved, and the requirement for improving the quality of the Chinese flowering cabbage is met.

Description

technical field [0001] The invention relates to the technical field of Chinese cabbage planting, in particular to a method for preparing a nutrient solution for improving the quality of Chinese cabbage and its product and application. Background technique [0002] With the rapid development of the vegetable industry, a large amount of non-edible or non-commercial vegetable stalks will be produced during the harvesting process of vegetable products. If these vegetable stalks are not properly disposed of, it is not only a waste of resources, but also pollutes the planting environment and spreads diseases and insect pests. , is not conducive to the future production of vegetables. Therefore, it is necessary to properly handle these vegetable stalks with appropriate processing technology to achieve harmless and resourceful utilization, which has very important practical significance for improving life and planting environment. [0003] Caixin, also known as cabbage sprouts, bel...
