Problems solved by technology

[0002] With the development of modern agricultural science and technology, countries adopt "soilless cultivation technology" to produce pollution-free vegetables or flowers, which are mainly divided into two categories: "substrate cultivation technology" and "substrate-free cultivation technology", but no matter which There are advantages and disadvantages in all technologies. Substrate culture has the problem of scientific drip irrigation of nutrient solution, and hydroponics has the problem of how to increase dissolved oxygen in water to p

Embodiment 1

[0022] Embodiment 1: the use of the spray cultivation technique of the present invention in the trough cultivation system

[0023] In the constructed greenhouse, connect the data line 3 and the sensor 2 to the operation center 1, then connect the data line 3 to the nutrient solution supply system device 4, and finally connect the liquid supply pipe 5 and Return pipe 6 and cultivation system trough type (trough type: it is to build a 1.5m wide, 20-30cm high, long (according to the length of the greenhouse) brick cement trough on the flat ground of the greenhouse, and the bottom of the trough is built with a slight slope and no leakage On the cement bottom of the tank, a nutrient solution return hole is left at the slightly lower end of the tank for the return and collection of the nutrient solution. Spray pipes are laid on the bottom of the tank and an atomizing nozzle that sprays upwards is installed to ensure that the entire inner space of the tank can be used for cultivation....

Embodiment 2

[0024] Embodiment 2: the use of spray cultivation technique of the present invention in tower cultivation system

[0025] In the constructed greenhouse, connect the data line 3 and the sensor 2 to the operation center 1, then connect the data line 3 to the nutrient solution supply system device 4, and finally connect the liquid supply pipe 5 and The return pipe 6 and the cultivation system tower type (tower type: choose plastic foam board as the material, punch holes on the board according to the planting density, and buckle the inverted V-shaped buckle of the planting board on the built support, which is made of profile Lay a thin film along the bottom surface of the frame or bricks to collect the returning nutrient solution. Suspend the mist pipe in the center of the tower to achieve uniform atomization without leaving any dead ends, and plant the crops wrapped with sponges in the planting hole) 11 connections.

Embodiment 3

[0026] Embodiment 3: the use of spray cultivation technology of the present invention in pipeline cultivation system

[0027] In the constructed greenhouse, connect the data line 3 and the sensor 2 to the operation center 1, then connect the data line 3 to the nutrient solution supply system device 4, and finally connect the liquid supply pipe 5 and Return pipe 6 is connected with cultivation system pipeline type (pipeline type: use plastic pipe as root region space, micro-nozzle pipe is installed in the pipeline, and the crop that is bound with sponge is planted in the planting hole on the pipe mouth of perforation) 12 again.

Abstract

The invention provides brand-new greenhouse soilless culture-fog culture technology, which is mainly soilless culture technology for utilizing an atomizing device to atomize a nutrient fluid into fog drops and directly spraying the fog drops on root systems of crops to provide the moisture and the nutrient needed by the growth of the crops. The crops are suspended in an airtight culture device (tank, box, barrel, pipeline, bed or triangular tower), the root systems are bared inside the culture device, and the nutrient fluid is atomized by the atomizing device and then is directly sprayed on the surfaces of the root systems. The invention provides a proposal which most effectively solves the water-gas contradiction of the root systems in all soilless culture technology at present (the technology can ensure that pores of the root systems, stems and leaves of the crops are easy to absorb the moisture and the nutrient needed by the growth, avoid the respiratory difficulty of the root systems in soil culture and water culture, furthest satisfy the water, fertilizer, air, temperature, and light needed by the growth of the crops, can make the crops quickly grow, and improve the yield by several times to tens of times; the technology also has no problems of the change of the pH value and the deterioration of the nutrient fluid during the production; the technology is easy for automation control and stereoscopic culture, and improves the utilization rate of greenhouse space; and the fog culture isolates the soil, minimizes the probability of plant diseases and insect pests, is easier to achieve pesticide-free culture, and realizes real nuisanceless crop production).

Description

technical field [0001] The invention relates to a new greenhouse soilless cultivation-spray cultivation technology, which belongs to the field of plant soilless cultivation. technical background [0002] With the development of modern agricultural science and technology, countries adopt "soilless cultivation technology" to produce pollution-free vegetables or flowers, which are mainly divided into two categories: "substrate cultivation technology" and "substrate-free cultivation technology", but no matter which Both technologies have advantages and disadvantages. Substrate culture has the problem of scientific drip irrigation of nutrient solution, and hydroponics has the problem of how to increase dissolved oxygen in water to prevent root rot. Among them, the "substrate-free cultivation" represented by Japan's "hydroponics" is relatively advanced, and has been popularized and applied in a large area in various countries, but there are still the following insurmountable short...
