Embodiment 1

[0029] Embodiment 1 A kind of seed collection method of vegetable burdock pure three-year-old

[0030] 1. Cultivation of the mother plant

[0031] Include the following steps:

[0032] 1. Regional plot selection

[0033] For the production of the female parent of burdock, it is best to choose in the cold and cool areas in the north where the temperature difference between day and night is large, especially Jilin Province in the northeast and Zhangye in Gansu in the northwest. These areas have a large temperature difference between day and night and a long annual growth period, which is suitable for the accumulation and storage of nutrients in the female parent of the burdock. The selected plot requires flat terrain, sandy loam soil with a soil layer thickness of not less than 100cm, good irrigation and drainage, loose and fertile soil, and a sand content of not less than 30%; the pH value is required to be alkaline, and the pH value is preferably 7.0-7.5 .

Embodiment 2

[0120] The single factor optimal experiment of embodiment 2 sowing period

[0121] Adopt the pure three-year seed collection method described in embodiment 1, only change the sowing period, carry out experiment.

[0122] Test time: September 2011-July 2012

[0123] Test site: Demonstration Park of Institute of Biology, Weifang Academy of Agricultural Sciences

[0124] Experimental Variety: Liuchuan Ideal

Embodiment 3

[0141] Example 3 Maternal colonization period single factor analysis experiment

[0142] Adopt the pure three-year seed collection method of burdock described in embodiment 1, only change in the female parent colonization step,

[0143] The time of mother plant colonization period, carry out single factor analysis experiment,

[0144] Test time: July 2012---September 2013

[0145] Test location: Huajialing Village, Guanzhuang Town, Anqiu City

[0146] Experimental Variety: Liuchuan Ideal

[0147] The following are the test results of the applicant on the colonization period and the incidence of plant virus diseases and the impact on the seed yield of a single plant of Liuchuan ideal burdock pure three-year-old son, see Table 4.

Abstract

The invention provides a seed collection method for vegetable burdock pure three-year seeds. The seed collection method comprises culturing stock plants, harvesting and storing female parents, and planting the female parents. The stock plant cultivation comprises selection of sowing time, the sowing time being 25th September to 5th October. Using the method can obviously reduce bolting rate of autumn sown burdock in second-year production field, the bolting rate of the second year being 0.32%. Burdock seeds produced by the method can substantially improve yield and commodity of burdock roots. Yield of the burdock roots is 47515.50 kg / hm<2>, and commodity output of the burdock roots is 43238.65 kg / hm<2>. Using the method, a single plant can produce about 1000 g of burdock seeds. Using the method can solve a problem of burdock seed localization, and breaks situation that high-quality domestic burdock seeds just depend on import.

Description

technical field [0001] The invention relates to a seed collection method of vegetable burdock pure three-year-old seeds, belonging to the technical field of burdock planting. Background technique [0002] Burdock is a kind of medicinal and edible plant. It is a biennial herb of Compositae. The main edible part is the hypertrophic fleshy root, and the petiole and young leaves can also be processed and applied. Burdock is native to China and was introduced to Japan from my country around 940 AD. After long-term selection and breeding, many cultivars have been bred and become one of the main root vegetables in Japan. Burdock root is rich in protein, amino acids, vitamins and inulin unique to Compositae plants. Its comprehensive nutritional value is much higher than that of carrots and yams. It is rich in inulin, cellulose, protein, calcium, phosphorus, iron and other nutrients needed by the human body. A variety of nutrients, burdock is also rich in dietary fiber, the conten...
