Brand-new greenhouse soilless culture-fog culture technology

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).

Method for enhancing training effectiveness

The present invention provides methods for exercise training to improve exercise performance in an individual using low-resistance positive airway pressure and specialized gas mixtures during or immediately after exercise. The methods include wearing an interface, i.e. mask, connected by a tubing circuit to a positive airway pressure (PAP) assist ventilator device. The PAP device is connected to flexible tubing connected through a pressure regulator to a liquid gas source which supplies the gas mixture. Optionally, a gas impermeable bag or vessel is connected to both the PAP device and the liquid gas source to receive, store and condition gas(ses) that is delivered to the PAP device from the liquid gas source. The methods also include simulating high altitude exercise training by using the PAP device with a hypoxic level of oxygen in the gas mixture. The methods of the present invention reallocate oxygen between muscle groups, improve oxygen delivery to muscles, improve oxygen utilization by muscles reduce fatigue, lessen episodes of dyspnea, improve conditioning levels and overall improve training to extreme levels of performance.
