Embodiment 1

[0031] The soilless and light simplified cultivation method of Chinese yam zero surplus seeds comprises the following steps:

[0032] The experiment site of this embodiment is in the vegetable base of the Economic Crops Research Institute of the Hubei Academy of Agricultural Sciences.

[0033] (1) Seed selection

[0034] Select Lichuan yam zero-yuzi with large individuals, full grain shape, undamaged skin, sparse pores, shiny surface, and no pests and diseases as the sowing material.

[0035] (2) Production of cultivation tanks

[0036] Dig trenches on the surface of the ground, lay cement boards around and at the bottom of the trenches, leave gaps between the cement boards, and make rectangular cultivation tanks. The specifications of the cultivation tanks are 25m long, 0.50m wide, and 0.45m high;

[0037] The cultivation tank is filled with a cultivation substrate; the substrate is a seedling cultivation substrate purchased from Wuhan Riqing Biotechnology Co., Ltd.

Embodiment 2

[0052] The soilless and light simplified cultivation method of Chinese yam zero surplus seeds comprises the following steps:

[0053] The experimental location of this example is the yam planting base of Huichuan Modern Agriculture Co., Ltd. in Lichuan City.

[0054] (1) Seed selection

[0055] Select Lichuan yam zero-yuzi with large individuals, full grain shape, undamaged skin, sparse pores, shiny surface, and no pests and diseases as the sowing material.

[0056] (2) Production of cultivation tanks

[0057] Dig trenches on the surface of the ground, lay cement boards around and at the bottom of the trenches, leave gaps between the cement boards, and make rectangular cultivation grooves. The specifications of the cultivation grooves are 25m long, 50cm wide, and 45cm high. Filling up the cultivation substrate; the substrate is 6 parts of corn stalks: 4 parts of slag (parts by weight).

[0058] Watering adopts the method of drip irrigation under the film. After the cultivat...

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...
