Description
Technical field
The present invention relates to a kind of its preparation and application of the mill water culture nutrient solution suitable for soybean nodulation, belong to water planting nutrition
Liquid technical field.
Background technology
Soybean is not only protein and oil source important in human food's structure, and is that typical biological nitrogen fixation is made
Object.The study found that the symbiotic nitrogen fixation that legume-rhizobium are formed accounts for about 60% or more of biological nitrogen fixation total amount, it is nitrogen-fixing efficiency
The most system of highest, amount of nitrogen fixation（Herridge, et al., 2008）.It is raw that soybean biological nitrogen fixation is applied to agricultural
Production can improve crop nitrogen nutrition, reduce nitrogenous fertilizer input, promote root growth and improve crop yield（Ferreira et
al., 2009）.In the soybean main production country such as the U.S., Brazil, Rhizobium Inoculation has become one of major measure of soybean yield-increasing.And
Legume inoculation technology is applied to agricultural production by China, also achieves good benefit（Tang Fuyue etc. 2011; Mendes et
