Rice culture solution and rice culture method

The invention belongs to the technical field of plant cultivation biology, and particularly relates to a rice culture solution and a rice culture method. A certain amount of melatonin is added into the rice culture solution, so that the technical problem of high difficulty in further improving the unit yield of rice is solved. Melatonin is added into the rice culture solution, so that the growth and development process of rice can be promoted to be obviously changed, including promoting the increase of rice biomass and promoting the elongation of the first tillering bud and the second tillering bud. Melatonin can also relieve the inhibition effect of amino acid with higher concentration on rice growth and tillering bud elongation. The melatonin and the hydroponic solution containing the melatonin can be applied to agricultural practical activities of rice cultivation, so that the unit yield of rice is effectively increased. 本发明属于植物培育生物技术领域，具体涉及一种水稻培养液以及水稻培养方法。水稻培养液中加入一定量的褪黑素，解决了进一步提高水稻单产难度大的技术问题。通过在水稻培养液中加入褪黑
