Alfalfa Inoculation Rhizobium Note Elements
Although inoculation with rhizobia can increase the yield and quality of alfalfa, the use of microbial agents directly affects the effect of inoculation, which in turn affects the growth and yield of alfalfa. Therefore, when using rhizobia inoculants, the following factors must be considered: 1. Soil conditions. In an area, if it has never been planted or if it has not been cultivated for more than 5 years (the so-called new area), it is difficult for the soil to have rhizobia that matches the leguminous plant. The roots of leguminous plants also do not form nitrogen fixed nodules. Therefore, the cultivation of alfalfa in the new area must be inoculated with matching rhizobia agent, will show the advantages of symbiotic nitrogen fixation. In addition, the inoculation of rhizobia in sandy or poorly nutrient soil can also effectively improve the growth of alfalfa and increase soil fertility. On the contrary, in the soil where alfalfa was grown continuously, inoculation of rhizobia could increase production, but the increase was not significant. 2, Rhizobium and alfalfa matching. In general, only the inoculation of rhizobia with good compatibility with this type of alfalfa can increase the yield. If the matching is poor, there is no effect of increasing the yield of inoculant rhizobia. In general, if the inoculated alfalfa is from the United States or Canada, the effect of increasing the yield of inoculated rhizobial bacteria is very obvious. If it is from other countries, a strict field trial is needed to determine. 3, fertilization level. The level of nitrogen application directly affected the amount of nodulation of alfalfa, and the high nitrogen application inhibited the formation of rhizobia, while the low nitrogen application had a slight promotion effect. Phosphorus fertilizer can improve the growth of roots, and thus promote the formation of tumors. Only comprehensive consideration of the above factors and inoculation of rhizobia according to the ecological conditions of the planting regions can improve the yield and quality of alfalfa, so that the majority of producers can obtain good economic benefits.
