The invention relates to a carbon-based fertilizer potentiating agent and application of the carbon-based fertilizer potentiating agent. The carbon-based fertilizer potentiating agent is characterized by comprising the raw materials in proportion by weight: 50-70 carbon powder, 5-15 humic acid, 2-5 inhibitors mixing urease inhibitor with nitrification inhibitor, 10-20 microelement fertilizer, and 5-10 acid bentonite or clay; biomass granule carbon is selected as a matrix carrier, the production process is simple, raw materials are easily obtained, and the cost is low. The biomass carbon has strong adsorbability, water retention property and light absorption warming property, and can be used as good ammonia stabilizer and soil conditioner except for the carrier. After being applied into soil, the potentiating agent can lead the fertilizer to slowly release, and can relieve the influence of drought and lacked water and low temperature on crop growth. The potentiating agent not only can improve the fertilizer utilization rate, but also is environment-friendly and safe, can effectively improve the utilization rate of nitrogenous fertilizer and phosphate fertilizer, reduce fertilizer loss, and simultaneously can lighten the water body pollution and greenhouse effect by nitrogenous fertilizer, reduce the content of nitrate nitrogen in agricultural products, and ensure the safety production of food.

An apparatus for growing vine crops in a greenhouse comprises a first media carrier, a first nutrient supply means, a first support means, a regulating mechanism, a main cable, a plurality of load differential mechanisms, a second media carrier, a second nutrient supply means, and a second support means. The second media carrier is above and in substantial parallel with the first media carrier. The distance between the first media carrier and second media carrier is adjusted by the regulating mechanism. A method for growing vine crops in a greenhouse comprises two growing modes: a single crop growing mode, and a vertical dual crop growing mode. The sequence of this process begins with a first single crop growing mode, followed by a vertical dual crop growing mode, and then followed by a second single crop growing mode. A single crop growing mode: first crops grow in the first media carrier fed by the first nutrient supply means, trained by the first support means. A vertical dual crop growing mode: the first crops grow in the first media carrier fed by the first nutrient supply means trained by the first support means; and second crops grow in the second media carrier above the first media carrier fed by the second nutrient supply means and trained by the second support means.
