Embodiment 1

[0037] This embodiment relates to a fertilization method integrating water and fertilizer in facility cultivation, specifically fertilizing water-soluble fertilizer through a drip irrigation pipe network, wherein the preparation method of the water-soluble fertilizer includes the following steps:

[0038] S1. Dried the straw, bagasse and poultry manure and crushed to a particle size of no more than 2mm, added water to adjust the solid content to 15-16%, adjusted the pH value to 7-8, adjusted the C / N to 25:1, and added to ferment Conditioning agent, after stirring evenly and standing still, the fermentation raw material is obtained;

[0039] S2. Adding the first composite strain to the fermentation raw material and performing the first aerobic fermentation under the condition of supplying air, the fermentation temperature is 60-70° C., and the fermentation time is 10-15 days to obtain the first fermentation liquid;

[0040] Wherein, the first composite strain is a combination of ...

Embodiment 2

[0048] A fertilization method integrating water and fertilizer under facility cultivation, specifically fertilizing water-soluble fertilizer through a drip irrigation pipe network, wherein the preparation method of the water-soluble fertilizer comprises the following steps:

[0049] S1. Dried the straw, bagasse and poultry manure and crushed to a particle size of no more than 2mm, added water to adjust the solid content to 15-16%, adjusted the pH value to 7-8, adjusted the C / N to 25:1, and added to ferment Conditioning agent, after stirring evenly and standing still, the fermentation raw material is obtained;

[0050] S2. Adding the first composite strain to the fermentation raw material and performing the first aerobic fermentation under the condition of supplying air, the fermentation temperature is 60-70° C., and the fermentation time is 10-15 days to obtain the first fermentation liquid;

[0051] Wherein, the first composite strain is a combination of yeast, actinomycetes,...

Embodiment 3

[0057] With embodiment 1, the preparation method of described straw biochar is:

[0058] Peel corn, sorghum, rapeseed or cotton stalks and cut them into small pieces, wash the obtained stalks several times with deionized water and ethanol and dry them, then put them into a high-temperature atmosphere tube furnace after ball milling, and heat up in a protective atmosphere To 1000-1200 ℃, keep warm and carbonize for 60-100min, after cooling to room temperature to obtain carbonized product, immerse the carbonized product in 1-2mol / L hydrochloric acid solution to remove impurities, then wash with deionized water until neutral, and dry to prepare Obtain the straw biochar.

[0059] The solid content of the fermentation broth described in this example was measured to be 4.1%.

Abstract

The invention provides a facility cultivation water and fertilizer integration system and a fertilization method, belonging to the technical field of crop fertilizers, fertilizing water-soluble fertilizers through drip irrigation pipe networks, wherein the preparation method of the water-soluble fertilizers uses agricultural and forestry organic wastes as raw materials, through Adjust moisture, pH, C / N and add it as a fermentation regulator to obtain fermentation raw materials, then inoculate the first composite strain and the second composite strain in turn and carry out aerobic fermentation respectively to obtain fermentation broth, and expose the fermentation broth to After aeration, the third composite bacterial strain is added and cultivated for 3-5 days to obtain a water-soluble fertilizer; the water-soluble fertilizer has high organic substrate utilization rate and solid content of fermentation liquid, and is suitable for application through drip irrigation pipe network.

Description

technical field [0001] The invention relates to the technical field of crop fertilizers, in particular to an integrated water and fertilizer system for facility cultivation and a fertilization method. Background technique [0002] Water and fertilizer integration technology is a new agricultural technology that uses irrigation system to integrate irrigation and fertilization. technology. The irrigation water dissolved with fertilizer passes through the sprinkler (nozzle, micro-nozzle and dripper, etc.), and the fertilizer solution passes through the pipe and the dripper to form drip irrigation, which can evenly, regularly and quantitatively infiltrate the growth area of ​​the crop root system. It can also precisely regulate soil moisture and nutrients according to soil properties, crop growth, and water and fertilizer requirements, and has the advantages of saving water, energy, labor, increasing production and income, and facilitating large-scale management and standardize...
