Analysis on the Growth Performance and Nutritional Ingredient of Minbeiguanlu Azolla Filiculoides Lam.

In order to select the new varieties of Azolla imbircata Roxb. Nakai with high yield, good quality and good resistance, the growth performance and nutritional ingredient of a kind of Azolla filiculoides Lam. with better characters by preliminary observation (tentatively named:Minbeiguanlu) were analyzed, which was collected from Guanlu Village of Pucheng County in Jianyang District of Nanping City from 2017 to 2019, by taking Longyin Azolla filiculoides Lam. and Minyu No.1 as the control group. The results showed that the yield of Minbeiguanlu Azolla filiculoides Lam. was higher than that of the two control varieties, which had the advantages of cold resistance and high nutrient content, etc. The water content and crude protein content of Minbeiguanlu Azolla filiculoides Lam. were 94.58% and 22.50%, respectively. The dry weight of annual yield from 2017 to 2018 was 9 325 kg·hm^-2, which was 8.61% higher than that of Minyu No.1 (with significant difference), and 17.46% higher than that of Longyin Azolla filiculoides Lam. (with highly significant difference). Meanwhile, the dry weight of annual yield from 2018 to 2019 was 9 838 kg·hm^-2, which was 4.04% higher than that of Minyu No.1 (with not significant difference), and 10.90% higher than that of Longyin Azolla filiculoides Lam. (with highly significant difference). The comprehensive evaluation showed that Minbeiguanlu Azolla filiculoides Lam. was a new variety with better performance in the comprehensive characters such as the yield, nutrient and cold resistance, etc.
