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).
