Dafu Science and Technology Commission of Anhua County, Hunan Province, cultivation of lotus root to use its top bud instead of species, not only can save a lot of lotus root, and the yield than the lotus root population increased. Generally use all the lotus body for species, each kind of lotus root need 300 kilograms, the cost is higher. Reproductive technology with the top buds are as follows: 1. Nursery.
