Study on the Changing of Quality Characteristics of Alfalfa under Different Treatment Conditions

doi:10.7668/hbnxb.201751716

Abstract

Abstract: In order to comparing the effects of different treatments on the quality of alfalfa, this experiment designed the comparison of alfalfa quality under different conditions, different periods, different stubble heights, different growth sites and whether it was raining. The results showed that the quality of the first and fourth cuttings was significantly better than the second and third; with the growth period extended, the quality of alfalfa gradually decreased, but comprehensive considering, quality was better under the present bud-early flowering, and the yield was higher. The quality of alfalfa leaves was significantly better than that of stems. The retention of alfalfa 8-10 cm not only ensured the yield, but also maintained good quality characteristics. Meanwhile，turning it on in time after raining was important to ensure its quality characteristics.Therefore, the comprehensive comparison of the height of stubble at harvest should not be too low, and the harvest period should not be too late. The cultivation of leafhopper is an effective way to improve the quality of alfalfa.

Key words: Quality, Stubble height, Growth period, Growth site, Raining
