Abstract

The invention discloses a method for cultivating Chinese yams without setting up Chinese yam holders, and belongs to the technical field of Chinese yam cultivation. The Chinese yams are planted in a single-ridge way, two ridges share one holder, a row of spring corn is spaced-sowed between every two ridges timely, two to three plants are arranged in one cave, the uncoiled-vine stage of the Chinese yams is identical to the seedling stage of the spring corn, the grown spring corn is used as the holders, when the harvest is carried out in autumn, the straw of the corn and the straw of the Chinese yams are smashed and returned to the field, and thus mechanized cultivating of the Chinese yams in the whole process is realized without the need of removing the Chinese yam holders and the stems and vines.
