A fertilizer composition according to an embodiment may reduce methane gas emission. The fertilizer composition includes ethephon as an effective component, and has an excellent effect of reducing the emission amount of methane gas from soils in which crops are cultivated. As the fertilizer application can be reduced to one application, labor can be saved and also environmental contamination can be prevented.

The invention is a method for enhanced growth of mycelium in culture including the key steps of seed blend choice from among corn, rice, quinoa, chia, canihua, cumin and flax seed, germinating the seed blend prior to inoculating the mycelium starter, and conducting the mushroom cultivation with water and particular transmissions of sound and particularly colored light. Mushrooms grown by such a method not only mature in 13-15 days rather than 21 days, but have an enhanced nutritional and medicinal profile along with absence of unwanted organism contaminants whose unwanted overgrowth occurs during days 16-21 (or days 16-28) of typical mushroom culture.

A noninvasive method of source-sink regulation in rice belongs to the technical field of rice production. In this method, the source-sink relationship is regulated by a rice sterile line and its identical type of maintaining line being subjected to mixed-planting and insulated pollination, or sowing and transplanting at different times and insulated pollination, so as to construct rice plant samples with gradient difference of source-sink levels. The present invention is a kind of native, natural noninvasive method of source-sink regulation, which could broaden the traditional thinking of source-sink theoretical research, especially overcome the deficiency in conventional methods such as leaf-cutting, spikelet-thinning that lead to physical injury or physiological interference. The method provides a brand new approach and solution for thoroughly investigating source-sink relationship in rice, wheat, maize and other crops, and will play an important role in enriching crop source-sink theory and also promoting the development of the related disciplines.

A novel plant growth-promoting agent and a plant growth-promoting method using the same are provided. The plant growth-promoting agent contains a lactic acid bacterium having a plant growth-promoting action. Also, in the plant growth-promoting method, a seed, a plant body and/or a soil is treated with a lactic acid bacterium having a plant growth-promoting action. Lactobacillus plantarum strain FERM BP-21501 is suitable as the lactic acid bacterium having a plant growth-promoting action.
