Analysis of growth,yield,and economic benefits of different purple alfalfa varieties
In order to screen suitable growth alfalfa varieties in Chongqing area and effectively improve the yield and economic benefits of alfalfa cultivation.Five types of purple alfalfa seeds(Zhongmu No.1,Zhongmu No.3,Gannong No.9,Aurora Australis,and Yumu No.1)were selected for the experiment and planted under the same conditions.They were cut during the initial flowering period.Select 5 replicate plots(1 m×1 m)for each type of purple alfalfa.Measure the growth and yield separately,and calculate the economic benefits.The results showed that:(1)Compared with Zhongmu No.1,the plant height of Zhongmu No.3 and Yumu No.1 purple alfalfa varieties was significantly increased(P＜0.05),with average values of 95.41cm and 94.72 cm,respectively.(2)Compared with Zhongmu No.1,the fresh weight,dry weight,fresh grass yield,and dry grass yield of Zhongmu No.3 and Yumu No.1 purple alfalfa varieties were significantly increased(P＜0.05).(3)The economic benefits of alfalfa varieties including Zhongmu No.1,Zhongmu No.3,Gannong No.9,Aurora Australia,and Yumu No.1 are 33120,37260,35280,35460 and 36540 yuan/hm2,respectively.Compared with Zhongmu No.1,the economic benefits of Zhongmu No.3 and Yumu No.1 purple alfalfa varieties significantly increased by 4140 and 3420 yuan/hm2(P＜0.05).Conclusion:Under the conditions of this experiment,Zhongmu No.3 and Yumu No.1 have the best growth,yield,and economic benefits,making them more suitable for promotion and planting in Chongqing region.
