The yield of banana lotus root tubers is 4000-5000kg per mu, and the stems and leaves are about 2000kg. Its energy and digestible protein are shown in Table 157-2.

According to the results of pig feeding and digestion tests conducted by Guizhou Agricultural College and Guizhou Animal Husbandry and Veterinary Research Institute, banana lotus root tubers can replace concentrates as fattening feed for pigs. 100kg of dried banana lotus flakes is equivalent to 74kg of corn. The total digestible energy used for fattening is equivalent to the nutritional value of 69kg of corn. There is no significant difference in the oil yield of flower oil, suet and fat oil between fattening pigs and corn fattening pigs. After banana lotus root stems and leaves are silage fermented, it has a sour aroma and pigs are willing to eat it. However, it has a lot of crude fiber, gum on the leaves, and low digestibility.

Banaco lotus root tubers are rich in starch. 12-13kg of starch can be extracted from every 100kg of fresh tubers. The starch can be made into vermicelli, vermicelli, and can also be processed into various pastries. Each 100kg of fresh tubers can be dried into 25-30kg pieces, and each 100kg of dried pieces can be used to brew 54kg of 45% white wine. Both the wine residue and powdered residue can be used as feed. According to the analysis of the Sichuan Provincial Animal Husbandry Institute, the powdered residue contains 94.8% moisture and crude protein. 0.95%, crude fat 0.88%, crude fiber 0.61%, nitrogen-free extract 2.75%, crude ash 0.32%. The powder residue can be used as feed and can be dried for long-term storage.

The stems and leaves of banana lotus root are rich in long fibers, which can be used to make ropes, weave straw bags, and can be used as raw materials for artificial fibers and papermaking. According to Zhejiang Province data, the stems and leaves contain 14.18% moisture and cellulose. 49.27%, sodium hydroxide extract 32.02%, lignin 7.71%, ash 4.87%, and according to Yunnan Province data, it contains 73% A fiber. The flowers can be used as vegetables and taste like daylilies. The chemical composition of banana lotus root is shown in Table 157-3.

The banana lotus root plant is tall and requires a large amount of fertilizer. It is necessary to apply heavy base fertilizer and top-dressing fertilizer once in the seedling stage and flowering stage to achieve high yield.

Banana lotus root requires deep soil to facilitate tuber enlargement. When combined with fertilization, it is necessary to till and cultivate the soil to prevent lodging.

If the stems and leaves are needed for feed, 1/4-1/3 can be cut each time during the growth process. Before frost, the stems and leaves can be cut 10cm above the ground and used as green fodder or silage. The underground tubers can be covered with grass and can be used as needed or kept for seeding. Tubers can also be stored indoors to avoid freezing damage.
