Nutritional characteristics of alfalfa powder(3)

4. Prediction of nutrients and the best harvest time

The nutrient composition of Mangiferin is directly affected by the ratio of stem to leaf and growth period. Therefore, according to the actual measured value of alfalfa leaf and alfalfa stem at different growth stages and the dry matter ratio of stem and leaf, Bitter Melon Extract is a good method to simulate and calculate the nutrient content of the whole plant in the aboveground part of alfalfa, which is a good method to avoid the sample error caused by the loss of leaves during sampling. The contents of nutrients in the stems and leaves of alfalfa were different in different growth stages. The peak value of crude protein content in leaves was at the initial Mangifera Indica Extract and full flowering stage, while the crude fiber content in leaves was contrary to this rule; the crude protein content of stem and leaf was the highest at full bud stage, and decreased with the growth period, and the peak value of crude fiber content in stem was in full flowering stage. The quality of alfalfa meal was the best at the initial flowering stage, followed by the full flowering stage, the second at the full bud stage, and the worst at the pod setting stage. Flax lignans can be seen that the best cutting time of Alfalfa should be combined with the ratio of stem to leaf and its nutrient content, and it is ideal to select the first flowering stage and the full flowering stage. Under the condition of less sample quantity and extensive sampling method, the simulation prediction is more practical than the actual sampling.
