Soilless lightening and simplifying cultivating method for yam bulbil

Abstract

The invention provides a soilless lightening and simplifying cultivating method for yam bulbil. The method comprises the steps of material selecting, cultivating groove preparing, seeding, field managing, nutrient and water managing and harvesting. The yam bulbil is planted in a cultivating groove containing with soilless culture substrates, water and nutrient managing is carried out according to different development stages of the yam bulbil, the yam bulbil can rapidly grow, the problems that the yam plating difficulty, the harvesting difficulty and the labor and investment are large are solved, and the restricts of the soil property, the soil microbe damage and the crop rotation are overcome. By utilizing the method, the fresh weight of produced underground tubers ranges from 150 g to 205 g. The produced yams are good in quality, and can be used as potato seeds to be planted in the next year. Fifteen thousand to twenty thousand plants of the yam bulbil are planted in an area of 667 m <2> appropriately, and 30-40 workers needed in the traditional method of harvesting and digging potato seeds are reduced to 4-5 workers.

Description

technical field [0001] The invention relates to the technical field of crop planting technology, in particular to a soilless, light and simplified cultivation method of Chinese yam zero surplus seeds. Background technique [0002] Chinese yam is a plant of the genus Dioscorea in the Dioscorea family, and the tubers and dried tubers of Dioscorea opposite Thunb. are both edible and used as medicine. At present, most yams use vegetative organs for asexual reproduction, mainly including zero-surplus seed breeding, seed breeding and section breeding. Farmers are accustomed to using yam seeds for breeding, but if the seeds are used continuously, they are prone to problems such as degradation of species, serious pests and diseases, rough surface of yams, and poor quality. At this time, zero surplus seeds can be used to renew and rejuvenate the yam. The yam harvested in one year is used as seed potato by zero surplus seed planting, and the yam seed is planted in the second year, w...
