The difference between soilless culture and conventional culture is that the plants are cultured by directly using nutrient solution without soil. In order to fix plants and increase air content, most of them use gravel, sand, peat, vermiculite, perlite, rock wool, sawdust, etc. as fixing medium. Its advantages are high effect on controlling the temp, moisture, light, nutrients and air needed by fruit and vegetable during growth. The soilless culture of the fruits and the vegetables does not use soil, so that the planting range can be enlarged, the growth of the fruits and the vegetables is accelerated, the quality of the fruits and the vegetables is improved, the fertilizer and water are saved, the manual operation is saved, and the labor and the cost are saved.

The invention has local successful experience: soilless culture of leaf vegetables, annual culture of lettuce, one year cultivation of 8-9 crops, one mu per mu yield of 1 ten thousand kilograms per year, growth period from high to low with temperature, generally about 20-40 days. The tomato can be planted in spring and summer for one year, and the yield per mu can reach 1 ten thousand kilograms per year. The cucumber can be cultivated all the year round, and the economic benefit is good.

Example (b): management of nutrient solution: the research invents a nutrient solution management method suitable for the cultivation system, adopts a method of directly adding nutrient solution and fertilizer into a substrate in groups respectively, and changes the concept and management method of the traditional nutrient solution. The traditional nutrient solution is prepared by dissolving large, medium and trace element fertilizers together, especially in south areas, wherein the acidity of natural water and shallow groundwater can be both the natural water and the shallow groundwater; chemical precipitation is easy to generate in the preparation process, the pH value of the nutrient solution is generally required to be adjusted by acid, and farmers are difficult to master; the method for complexing heavy metal ions is also used for solving the chemical precipitation, and the cost is high; the problem of nutrient solution becomes a main bottleneck for the popularization of the soilless culture technology; and the investment of the nutrient solution preparation pool is also high.

The invention adopts a method that nutrient solution fertilizers are respectively and directly added into a matrix in groups, fertilizers capable of forming chemical precipitates are separated, a group of fertilizers are firstly added into a fertilizer tank, the fertilizers are dissolved and dripped into the matrix in the drip irrigation process, and after the fertilizers are fully dissolved; stopping drip irrigation, and adding another group of fertilizers until the drip irrigation is finished.

The management method of the nutrient solution comprises the following steps: at the initial stage of field planting, drip irrigation is not needed to supply nutrient solution, the root system of the vegetable is very small, most of nutrient solution of drippers cannot be absorbed by the root system, waste is caused, a certain amount of nitrogen, phosphorus and potassium fertilizer with the concentration of about 1 g/L can be dissolved by a bucket, the nitrogen, phosphorus and potassium fertilizer is manually poured around seedlings once a day for about 10 days continuously, and after the root system is basically connected, the nutrient solution is normally supplied by drip irrigation; in the initial stage of nutrient solution supply by drip irrigation, because seedlings are small, water consumption and fertilizer consumption are low, 0.5 cubic meter of water fertilizer or leaf fertilizer is drip-irrigated every day, and one group of fertilizer is added in the morning and afternoon; in autumn and winter, the irrigation quantity is controlled to be about 1 cubic meter every day generally according to the seedling condition and the weather, the drip irrigation is carried out in the morning on sunny days, and the irrigation is not carried out on cloudy days; the irrigation amount can be determined by observing the nutrient solution accumulation in the cultivation tank. The temperature in spring is high, the illumination is sufficient, the cherry tomato growth amount is large, and the water fertilizer or leaf fertilizer amount is 1.5-2 cubic meters every day.

The fermentation liquor is 1 hundred million per kilogram to 100 hundred million per kilogram, and even can be seen to be rich in 50 hundred million, 100 hundred million and 300 hundred million active probiotics, lactobacillus, saccharomycetes, clostridium butyricum, bifidobacterium and gram-positive coccus per kilogram.

The liquid inlet pipe for soilless culture comprises a main liquid inlet pipe and a branch liquid inlet pipe, wherein the input end of the main liquid inlet pipe extends into the nutrient solution storage tank; the cultivation tank is characterized in that a plurality of isolated planting bins are formed in the inner cavity of the cultivation tank through isolation plates in a separated mode, a liquid inlet cavity is formed in the middle of the cultivation tank, and the isolated planting bins and the liquid inlet cavity are arranged in an isolated mode through a penetration net respectively; nutrient solution at the bottom of the culture solution flowing cavity enters the isolated planting bin through the infiltration net.

The liquid outlet end of the nutrient solution flowing cavity of each cultivation and planting groove is communicated with a nutrient solution storage tank through a liquid outlet pipe, and the liquid inlet end of the nutrient solution flowing cavity is communicated with the nutrient solution storage tank; thus, the nutrient solution in the nutrient solution storage tank is conveyed to the culture solution flowing cavity in each culture bin by the high-pressure pump and then returns to the nutrient solution storage tank through the liquid outlet pipe; thereby realizing the circulation flow of the nutrient solution in the nutrient solution flow cavity.

The liquid part of the nutrient solution is normally irrigated with 500 times of water of 100 times of the original solution (fermented original solution), 10-30 times of water for preventing and controlling leaf surface diseases and pests, and the solid part is used as base fertilizer.

The problem that the soilless culture of vegetables needs attention in planting is that trace elements mainly including chelated metal elements or metal oxides containing calcium, magnesium, boron, iron, zinc, sulfur and molybdenum are added into water fertilizer or leaf fertilizer;
