Soilless culture refers to a culture method in which water, grass carbon or forest leaf mold, vermiculite and other media are used as substrates for fixing plants, and the plant roots can directly contact with nutrient solution. The components of the nutrient solution in the soilless culture are easy to control and can be adjusted at any time. In places with proper illumination and temperature and no soil, such as deserts, beaches and barren islands, the method can be carried out as long as a certain amount of fresh water is supplied. Soilless culture is divided into hydroponic culture, fog (air) culture and matrix culture according to the difference of culture media. Hydroponics is a cultivation method in which the root system of a plant is directly contacted with a nutrient solution without using a substrate. The earliest hydroponics was to immerse the plant roots in nutrient solution for growth, which resulted in oxygen deficiency and death of the roots in severe cases. The water culture method of a nutrient solution membrane method is usually adopted, even if a layer of very thin nutrient solution layer continuously and circularly flows through the root system of the crop, the water and nutrient of the crop are continuously supplied, and the fresh oxygen of the root system is continuously supplied. The advantages of soilless culture are: 1. water saving, fertilizer saving and high yield: various nutrient elements required by crops in soilless culture are artificially prepared into nutrient solution for application, the water loss is less, the nutrient components are kept balanced, the absorption efficiency is high, and the nutrients are scientifically supplied according to the types of the crops and different growth stages of the same crop. Therefore, the crops grow vigorously and have strong growth potential, and the yield increasing potential can be fully exerted. 2. Clean and sanitary without pollution: organic fertilizers are applied in soil cultivation, the fertilizers are decomposed and fermented to generate odor to pollute the environment, eggs of a plurality of pests can be bred to harm crops, and inorganic fertilizers are applied in soilless cultivation, so that the problems are solved, and the pollution of harmful substances such as heavy metals in polluted soil can be avoided. 3. Labor saving, labor saving and easy management: the soilless culture does not need operations such as intertillage, land plowing, weeding and the like, and is labor-saving and labor-saving. The watering and top dressing are simultaneously realized, the liquid supply system supplies the liquid regularly and quantitatively, the management is convenient, the waste is not caused, and the labor intensity is greatly reduced. 4. Avoiding continuous cropping obstacles: in the field planting management of vegetables, the reasonable rotation of land and the avoidance of continuous cropping are one of the important measures for preventing serious occurrence and spread of diseases. The problem can be fundamentally solved by adopting the soilless culture method particularly for water culture. 5. The method is not limited by regions and fully utilizes the space: the soilless culture method can ensure that the crops are completely separated from the soil environment and are not limited by soil quality and water conservancy conditions, and a plurality of deserts, wastelands or regions which are difficult to cultivate on the earth can be utilized by adopting the soilless culture method. The restriction of land is eliminated, the soilless culture can be free from the limitation of space, and the culture area is invisibly enlarged by utilizing the plane roofs of urban abandoned plants and buildings to plant vegetables and flowers. 6. Is beneficial to realizing agricultural modernization: the soilless culture enables the agricultural production to get rid of the restriction of natural environment, and the production can be carried out according to the will of people, so the soilless culture method is a production mode of controlled agriculture. The cultivation is carried out according to quantitative indexes to a greater extent, and the mechanized and automatic cultivation is favorably realized, so that the industrial production mode is gradually developed.

Hydroponics (hydroponics): hydroponics is a cultivation method in which the root system is fixed without the aid of a substrate and is directly contacted with a nutrient solution. Mainly comprises deep flow hydroponic culture (DFT), nutrient film culture (NFT) and floating capillary tube culture (FCH). 1) Deep liquid flow cultivation technology: the nutrient solution layer is deep, the root system extends in the deep solution layer, and the liquid amount occupied by each plant is large, so that the concentration, the dissolved oxygen, the pH value, the temperature and the water storage amount of the nutrient solution are not easy to change rapidly, and a stable growth environment is provided for the root system. 2) Nutrient solution membrane technology: is a water culture method for planting plants in a shallow flowing nutrient solution. This technique is because of the liquid layer is shallow, and crop root system is partly soaked in the nutrient solution that the shallow layer flows, and another part then exposes in planting the moisture in the groove, can solve root system aerobic problem betterly, nevertheless because the liquid measure is few, easily receives ambient temperature to influence, requires meticulous management. 3) The floating plate capillary tube cultivation technology comprises the following steps: the root dividing technology of floating plate wet felts arranged in the cultivation bed is adopted to create an oxygen enrichment environment for cultivating wet air roots and solve the water-gas contradiction; a long horizontal cultivation bed is adopted to store a large amount of nutrient solution, the defects of NFT are effectively overcome, the rhizosphere environment condition of crops is stable, the liquid temperature change is small, and the influence on the supply of the nutrient solution due to temporary power failure is avoided.

And (3) substrate culture, wherein the substrate culture is characterized in that the root system of the cultivated crop is fixed by a substrate. The root system of the crop is fixed in an organic or inorganic matrix, wherein the organic matrix comprises peat, rice hulls, barks and the like, and the inorganic matrix comprises vermiculite, perlite, rock wool, ceramsite, gravel, sponge soil and the like which can be used as a supporting medium, and the crop nutrient solution is supplied by a drip irrigation or trickle irrigation method. In most cases, the substrate cultivation has the advantages of coordinated water, fertilizer and gas, sufficient supply, low equipment investment, convenience for local material taking, and excellent and stable production performance; the disadvantages are large volume of the matrix, time and labor consumption and great difficulty in filling, disinfection and residual root treatment during recycling.

The utility model discloses soilless culture co-culture system adopts the irrigation system that aquaculture water is direct to be connected with water planting, matrix culture, and the waste liquid that the breed district discharged directly circulates to basin, matrix groove or cultivation container in order to drip irrigation's mode, filters the back via absorption of plant to the interior material of cultivation water and cultivation matrix, returns aquaculture water to water collection again, and this kind of mode design is more simple, with irrigation pipe lug connection plant groove or container formation circulation can. Optionally, the culture medium must be selected from gravel or ceramsite with the particle size of more than 5mm (the diameter of more than 5mm), the filter effect of the medium is good, the water circulation cannot be influenced due to filtration overload, common soilless culture perlite, vermiculite or waste mushroom residue medium cannot be used, and the ecological balance of the system is easily damaged due to poor drainage.

Optionally, the core of soilless culture is to use nutrient solution to replace soil to provide mineral nutrient elements required by plant growth, so in the soilless culture technology, whether a nutrient solution with a proper concentration and a coordinated proportion can be provided for plants is the key of successful culture. The nutrient solution is one of the sources of plant root system nutrition in soilless culture, and all mineral nutrient elements necessary for crop growth, namely major elements such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulfur (S) and trace elements such as iron (Fe), manganese (Mn), boron (B), zinc (Zn), copper (Cu) and molybdenum (Mo) are contained in the nutrient solution. Different crops and varieties, different growth stages of the same crop, have great difference on the actual needs of various nutrient elements. Therefore, when the nutrient solution is selected, the required amount of various essential elements of different varieties and various growth stages is firstly known, and the composition and the proportion of the nutrient solution are determined based on the required amount. On one hand, the fertilizer absorption and fertilizer absorption characteristics of crops are considered according to the actual requirements of the crops on various nutrient elements. Alternatively, the nutrient solution may be one commonly used in the art, such as: 1. hoagland's hydroponic nutrient solution: hoagland's hydroponic nutrient solution was published in 1933 by Hoagland and his research partners after a large number of comparative tests, which is the most primitive but still in use classic formula. 2. Stainer (Steiner) nutrient solution: the Steiner nutrient solution finally determines the proportion and the concentration of various nutrient elements in the formula through the chemical equilibrium among the nutrient elements, is used more internationally and is suitable for the soilless culture of common crops. 3. General nutrient solution for Japanese garden test: the general nutrient solution for the Japanese garden test is developed and proposed by the Japanese Xingjin gardening test field, is suitable for various vegetable crops, and is called as a general formula. 4. Kawasaki nutrient solution: the formula of the Kazaki-Miyazaki nutrient solution is a nutrient solution formula which is prepared after the nutrient element absorption concentrations of various vegetable crops are measured in 1966-1976 and is suitable for various crops. On the basis of the classical formulas, a plurality of nutrient solution formulas more suitable for different plant growth can be optimized by utilizing the existing advanced and scientific technical means. It is desirable to select as much as possible a nutrient solution of the prior art that has less effect on the growth of aquatic animals.

The fertilizer can reduce water loss and evaporation, reduce drought pressure, preserve fertilizer, reduce chemical fertilizer, reduce saline-alkali damage, and improve fertility under the condition of reducing the dosage of the chemical fertilizer or gradually replacing the chemical fertilizer, so that the yield of grain crops, economic crops, vegetables and fruits is greatly increased. The quality of agricultural products is improved, the fruits are bright in color and luster, neat and mature, the sugar content and the vitamin content of the melon agricultural products are improved, the taste is good, the expansion of export is facilitated, and the selling price is improved. The agronomic characters of the crops are improved, the stems of the crops are thick and strong, the leaves are dark green, the flowering is advanced, the fruit yield is high, the commodity of the fruits is good, and the time to appear on the market is increased. The disease resistance and the stress resistance of crops are enhanced, the diseases and soil-borne diseases of the crops caused by continuous cropping are reduced, and the morbidity is reduced; the pesticide composition has good effects of preventing and treating mosaic disease, black shank, anthracnose and the like, and simultaneously enhances the comprehensive defense capability of crops to adverse environments. The reduction of the fertilizer application amount correspondingly reduces the content of nitrate in agricultural products. Tests prove that the ecological organic fertilizer can reduce the nitrate content of vegetables by 48.3-87.7 percent on average, improve the nitrogen, phosphorus and potassium content by 5-20 percent, increase the vitamin C, reduce the total acid content, increase the reducing sugar and improve the sugar-acid ratio, and particularly can obviously improve the taste of uncooked food parts for tomatoes, lettuce, cucumbers and the like.

Preparing a microbial organic fertilizer: in the prior art, an organic fertilizer fermentation strain is a composite strain developed by a high-tech biotechnology, can quickly decompose organic matters, has the advantages of small addition amount, strong protein degradation, short fermentation time, thorough decomposition, low cost, unlimited fermentation temperature and the like, and can effectively kill harmful bacteria, insects, ova and grass seeds in the fermentation product and degrade antibiotic residues. Rapid propagation, strong vitality, safety, no toxicity and the like.

The fermentation method comprises the following steps:

the method comprises the following steps: 1 bottle of the strain of the Ganshenle strain, 1 kilogram of brown sugar and 15 kilogram of water, and sealing and placing for 3-7 days for activation;

step two: diluting with water 50 times after activation, and spraying and uniformly mixing with a fertilizer to be fermented;

step three: adding the nong Sheng le bacterial liquid, and stacking the fertilizer to ferment for 5-10 days;

note that: if the conditions are satisfied, the fermentation process is preferably performed by turning over and pushing the mixture for 1 to 2 times.

When the method is implemented, the discharged residual bait and excrement are replaced by the fishpond for fermentation, and the specific method comprises the following steps:

the most important link of the water quality regulation of the soilless culture co-culture system is how to decompose organic matters by using microorganisms remotely. If a septic tank (or a fertilizer collecting fermentation box 6) is arranged, the excrement can be collected and decomposed by throwing microorganisms. In the aquaculture pond (aquatic animal feeding pond 3), the position where the most concentrated organic matters are placed is a material platform or a pond bottom (or the pond bottom), the organic matters deposited at the bottom are washed and brought into a septic tank (or a fertilizer collecting and fermenting box 6) as far as possible through flowing water, and enzymes mainly containing saccharomycetes are supplemented to the septic tank (or the fertilizer collecting and fermenting box 6), so that the organic matters enriched at the bottom of a water body can be decomposed in a facultative anaerobic environment, and a circulating water system of a soilless culture co-culture system is adjusted. When the concentration of a large amount of organic matters suspended in the water body reaches a certain degree, appropriate spore raw powder needs to be supplemented to decompose the microbial organic fertilizer, then the microbial organic fertilizer is separated from water, and the fertilizer is diluted in the blending box 7 respectively, is proportioned and then is conveyed to the plant hydroponics component 1, and flows downstream in sequence, so that the growth of plants in the plant hydroponics component 1 and the plant substrate cultivation component 2 is promoted.

Some thalli are relatively high-quality protein sources such as yeast, lactic acid bacteria and the like. The fermentation technology is adopted, the mixed and deposited pollutants are fermented in a septic tank (or a fertilizer collecting and fermenting box 6), then a carbon source is continuously supplemented, and the supplement of the ferment and the algae activating element are combined, so that when the water color is too thick, the spore raw powder is properly used, and the fermented microbial organic fertilizer is formed.

The water concentration indicates that the organic matters are more, and when the weather is relatively good (cloudy, cloudy and sunny), spore raw powder and enzyme are splashed. When the temperature rises and the aquatic animals grow vigorously for several months, splashing spore raw powder and enzyme once in 1-2 days as long as the weather turns good (cloudy, cloudy and sunny); when the weather is poor (rainy days and cloudy days), more fermentation liquor needs to be poured. When the weather is rainy or the natural bait is not supplied enough, oil cake (rapeseed meal), wheat middling and the like are added into the fermentation liquor for fermentation.
