The invention relates to the technical field of rice planting methods, in particular to a
nutrient solution for cultivating fragrant rice glutinous rice
black rice and application and a cultivation method of the
nutrient solution. Aiming at black grasses, a common rice
nutrient solution added with exogenous
amino acid and exogenous
organic acid can be used, and a common rice
nutrient solution subjected to compound treatment by adding
phenylalanine with the final concentration of 0.4 mM and
salicylic acid with the final concentration of 5 mu M can be added. The
nutrient solution for culturing the fragrant rice glutinous rice
black rice can be applied to the aspect of improving the rice quality, especially the fragrant rice glutinous rice
black rice. According to the
nutrient solution for culturing the fragrant glutinous rice'black rice ', the
plant height, the
biomass (
fresh weight), the
nitrogen content, the
chlorophyll content and the
single plant dry weight of the'black rice' can be effectively improved. The problem of poor growth and development of the black grasses in a common nutrient solution can be solved, the adaptability of the black grasses is enhanced to a certain extent, the yield is slightly increased, and the process of building green
agriculture is promoted.
