Problems solved by technology

[0004] Using yam nose (yam reed head) and yam Duanzi (tuber section) as seedling cultivation materials is the main yam seed retention method followed in various parts of my country. The seedling reproduction coefficient is between 1:1-1:5. Consume 15-25% of the economic output as seeds; because there are many soil-borne pathogens in underground rhizomes, and the accumulation of pathogens year by year causes serious degradation of species, the more generations of this traditional method of saving seeds The poorer the quality of the propagated seedlings, the lower the commodity quality and economic output of yam; at the same time, the mixing of commodity production bases and provenance production bases further aggravates the process of yam species degradation

Embodiment 1

[0027] Embodiment 1: a kind of method utilizing Chinese yam zero-surplus seed to breed Chinese yam seedling, comprises the following steps:

[0028] a, the preparation of zero-surplus seed sowing materials: (1) selection of female parent plants, one year before the implementation of sowing seedlings, in the original seed nursery of Chinese yam, select no pests and diseases, grow vigorously and exhibit good plants to list, and pull out the plants in the field Weak plants, damaged plants, and mutated plants, and the residues in the field should be cleaned up; (2) The remaining seeds are harvested. In the middle and late October, after the branches and leaves above the ground turn yellow and withered, the remaining seeds are harvested, and the impurities are removed and the grain shape is retained. Plump, non-deformed, undamaged skin, sparse pores, shiny surface, and free from pests and diseases; (3) yam yam grading, using yam yam yam grading sieves with different apertures to cla...

Embodiment 2

[0036] Embodiment 2: a kind of method utilizing Chinese yam zero surplus child to breed Chinese yam seedling, comprises the following steps:

[0037] a, preparation of sowing materials for zero surplus seeds: (1) selection of female parent plants: in 2016, in the original seed garden of Chinese yam in Tuanbao Township, Lichuan City, 889 plants with no damage from diseases and insect pests, vigorous growth and good performance were selected to be listed, pulled out Weak plants, damaged plants, and mutated plants were removed from the field, and the residues in the field were cleaned up; (2) Harvesting of zero surplus seeds: on October 22, after the branches and leaves above the ground turned yellow and withered, harvest the zero surplus seeds, remove impurities and remove bad Retain full grain shape, non-deformation, undamaged skin, sparse pores, shiny surface, and no pests and diseases; (3) Grading of yam yam: use yam yam grading sieves with different apertures to classify the ...

Embodiment 3

[0047] Embodiment 3: a kind of method utilizing Chinese yam zero surplus child to breed Chinese yam seedling, comprises the following steps:

[0048] a. Preparation of zero-surplus seed sowing materials: (1) Selection of female parent plants. In 2016, in the original yam nursery of Qianping Village, Xintang Township, Enshi City, selected plants with no pests and diseases, vigorous growth and good performance were listed 786 plants, pull out the weak, damaged, and mutant plants in the field, and clean up the residues in the field; (2) Harvest the zero surplus seeds. On October 16, after the aboveground branches and leaves turn yellow and wither, harvest the zero surplus seeds and remove them. Remove impurities and retain the yam yam yam with full grain shape, non-deformation, undamaged skin, sparse pores, glossy surface, and no pests and diseases; (3) yam yam grading, use yam yam yam grading sieves with different apertures to classify the harvested and preserved yam The zero su...

Abstract

The invention relates to a method for reproducing common yam seedlings by common yam bulbils. The method includes the steps: a, common yam bulbil planting material preparation; b, seedling bed preparation; c, seeding; d, field management; e, common yam seedling harvesting. The method for multiplying the common yam seedlings by the common yam bulbils has the advantages that the characteristics of common yam varieties are restored, the function of variety rejuvenation is achieved, common yam seedling reproduction coefficient and supply capacity are improved, by integrated application of appliances such as a common yam bulbil grading sieve, a common yam bulbil seedling culture mat, a common yam vine support net and a common yam seedling separation inclined sieve, common yam seedling production cost, labor force and labor intensity are reduced, labor efficiency is improved, a common yam seedling production supply mode is improved, technical support is provided for normalization and standardization of the common yam seedlings, a specialized, intensive and scaled common yam bulbil and seedling production base can be built, and example verification test results show that the method is feasible.

Description

technical field [0001] The invention relates to a method for propagating yam seedlings by using yam zero surplus seeds Background technique [0002] Chinese yam (Dioseorea opposite Thunb) belongs to the family Stemonaceae, a plant of the genus Dioseorea. Yam is mainly used for medicine and then for food. It is also eaten mostly for medicinal purposes. When people eat yam, they think it can cure diseases, nourish, and of course satisfy hunger. Yam has developed to this day and has become an important international medicine and food crop. Yam mainly contains mucus juice, mannan, mannan polysaccharide, choline, glycoprotein, polyphenol oxidase, vitamin C, phytic acid, 16 kinds of amino acids, allantoin and 3,4-dihydroxyphenylethylamine , dopamine (domamine), etc., are important nourishing foods, which have pharmacological effects such as nourishing the spleen and stomach, promoting body fluid and benefiting the lungs, nourishing the kidney and astringent essence, etc. Trea...
