Thermophilic methane fermentation products growth regulative activity and influence on productivity and food value of alfalfa

摘要

The TMFP's effects on vegetative mass yield and seed productivity of alfalfa on different backgrounds of nitrogen mineral nutrition were studied. TMFP foliar spray of alfalfa in the stages, sensitive to plant growth regulators action (shoot and bloom stages) increased cytokinins content, vegetative mass yield ans protein content, particularly on the 0.25 N nitrogen mineral backgrounds. Alfalfa's seed productivity was increased in first and first and second vegetation years as a result.
