The Effects of Nutrient Fluid at Different Iron Levels on the Quality of Culturing Tartary Buckwheat Bud

[Objective] The purpose of the research was to provide basis for more scientific and rational application of iron fertilizer in production.[Method] With the nutrient fluid without adding iron as the check,the effects of iron-added nutrient fluid on the quality of culturing tartary buckwheat bud were discussed.[Result] Compared with the CK,the iron-added nutrient fluid made the iron accumulation in Tartary buckwheat bud increase 1.94 times,the contents of the total sugar,chlorophyll,vitamin C,and soluble protein were increased by 19.79%,74.40%,78.19% and 42.91% resp.,and the contents of reducing sugar,fat and crude fiber were decreased 11.38%,6.56% and 20.83% resp.The contents of total combined amino acids and total free amino acids were increased by 5.80% and 14.09% resp.and at the same time the ratio of amino acids in tartary buckwheat bud became reasonable.[Result] Culturing Tartary buckwheat bud with iron-added nutrient fluid could improve the nutritive quality and value of Tartary buckwheat bud.
