Description

Biological film organic hydroponic planting system and operation method thereof
Technical Field
The invention relates to a biological film organic hydroponic planting system and an operation method thereof, belonging to the field of green agriculture.
Background
In the face of resource shortage and serious pollution, renewable resources are increasingly utilized in response all over the world. Many fertilizer feedstocks are ores and the vast majority of mining in recent years has caused these resources to begin to deplete. Meanwhile, energy is consumed in the process of manufacturing the chemical fertilizer, and the water source is polluted by carelessly using the chemical fertilizer and the pesticide, so that the ecology is influenced. Organic planting is an agricultural production system which does not use chemically synthesized fertilizers, pesticides and growth regulators in production, does not adopt genetic engineering and ion radiation technology, follows natural laws, recycles organic matters and agricultural wastes, and adopts farming, physical and biological methods to fertilize soil and prevent and control plant diseases and insect pests so as to obtain safe organisms and products thereof. In addition, when the organic fertilizer is decomposed by bacteria, besides basic nutrient elements, the organic fertilizer also generates abundant natural growth hormone and organic products, and the scientific research at present has little knowledge on the effects of the products on crop growth, disease resistance and the like, and the effects cannot be compared favorably with chemical fertilizers.
. However, the traditional organic planting has the problems of low yield, serious pest and disease damage, large manpower consumption and the like.
Chemical fertilizer hydroponics is commonly called water culture. Is one of the soilless culture modes. The method for planting plants is that the nutrient solution is dissolved in water, and then the nutrient solution is conveyed to the planted plants by a water pump. The nutrient solution flows in the cultivation tank by a water pump in a self-circulation way. The surface of each cultivation groove is covered with a cover plate with holes, the plants and the small cups are placed in the holes, and the roots of the plants are soaked in the nutrients to grow. The hydroponic culture has the advantages of rapid growth, large and stable yield, and can be applied to automatic equipment to save manpower: this is the greatest advantage of hydroponics, but needs to provide good growing environment, for example, proper temperature and sunshine are needed, and the high temperature of the greenhouse in summer will affect the growth of crops; hydroponic cultivation reduces the source of plant pathogens. However, after the nutrient solution or the substrate for hydroponics is used for several times, the excellent products are not easy to grow due to the release of a large amount of secretion at the root of crops and the accumulation of salt, so that the nutrient solution or the substrate needs to be discarded. Improper disposal may also cause environmental pollution, especially if large amounts of used nutrient solution are disposed of. In addition, without an ecosystem, chemical hydroponics requires an absolutely clean cultivation environment, since pathogens once invaded will multiply in large numbers in an environment without other bacterial constraints, and as water streams infect the entire cultivation system, most commonly root rot, more than 90% of the harvest loss can result. The organic hydroponics system and the organic cultivation are combined, namely the organic hydroponics, so that the output bottleneck of the organic cultivation can be solved, the labor input is reduced, the chemical fertilizer used in the hydroponics can be avoided, and the diseases can be overcome by using microorganisms. At present, the most successful and widely known organic hydroponic method is fish-vegetable symbiosis, and although the fish-vegetable symbiosis is a good organic hydroponic system, a plurality of problems often occur in the actual operation. The factors cause the problems of unstable symbiotic yield of fish and vegetables, difficult control of system balance, low economic benefit and the like.
The growth requirements of fish and vegetables are different, fish and vegetable symbiosis is that an aquatic environment is balanced between fish and vegetables, for example, the suitable pH of the fish is between 6.5 and 8, the vegetables are between 5.5 and 7, and if the balance is achieved, the pH is kept between 6.5 and 7 for a long time, but the balance is difficult to achieve in practice because a plurality of organic matters and oxidation action, nitrification action and the like of the organic matters in water affect the pH value of the water, and the floating range of the pH of 0.5 is difficult to control.
The fish and vegetable symbiotic nutrient source comes from fish manure, the fish nutrient requirement is different from that of vegetables, and the fish food is often overhigh in protein (causing overhigh nitrogen fertilizer), and slightly less in potassium, magnesium, calcium and the like, so that the nutrient absorption of vegetables is unbalanced. The current solution in the industry is to feed fish in large quantities to maintain a basic amount of low fertilizer elements or to add compounds to compensate for the vegetable requirements. Both of these methods have disadvantages, the former causing cost increase and the latter not meeting organic production standards.
The fish-vegetable symbiotic system generally uses a water tank to connect an air pump to realize intensive fish culture, and connects fish water with a vegetable bed to circulate the fish water. The intensive culture of the freshwater fish consumes more energy, needs facilities to be built, has higher cost and low economic benefit; in addition, due to the high fish culture density, the fish is easy to get ill, and once the fish die, the system can be stopped, and the vegetables are also affected.
