Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with specific embodiments.

[0016] A method for retaining seeds of Kohlrabi includes the following steps:

[0017] (1). Sowing: At the end of August, ground preparation will be carried out and seedlings will be thinned after emergence to ensure uniform growth of seedlings, and ternary compound fertilizer will be applied during the seedling period to promote the growth of seedlings.

[0018] (2) Transplanting: Transplant the seedlings when they are 27-30 days old. The seedlings have "cracked" and the roots swelled during transplanting. According to the growth of the roots, judge whether the kohlrabi is variant: the roots are larger and smaller, with only bilateral fibrous roots. Symmetrical seedlings are unvaried rutabaga; while the seedlings with roots full of fibrous roots (that is, there are many fine fibrous roots distributed on the roots) are the varieties produced by hybridization between this...

Abstract

A mosaic kohlrabi seed-keeping method comprises the steps of (1) sowing: soil working and sowing at the end of August; (2) transplanting: transplanting when the seedling age is 27-30 days, and removing the mutation when planting; (3) management: applying composite fertilizer when the yellow leaves fall off from the live seedling to be transplanted and new leaves grow, and spraying the seedling after transplanting by mixing 20 g imidacloprid with 15kg water; (4) re-planting: at the first ten days of December when dark frost comes, pulling out the mosaic kohlrabi and sunning it for one day; cutting off the leaves when planting on the second day, and transplanting it to the field edge or corner where white radish grows nearby; (5) harvesting: at the early June next year, pulling out the mosaic kohlrabi plant and putting it somewhere shelters from the rain; and threshing after ripening, shell removing, drying and collecting. According to the invention, the mosaic kohlrabi is pulled out for sunning for one day, then planted again, therefore the plant can grow from nutrition growth to reproduction growth; the mosaic kohlrabi is planted being mixed with white radish, therefore the anthesis can be postponed more than half a month, and the mosaic kohlrabi is prevented from mixed pollination with other cruciferous crops and avoiding biological hybrid.

Description

Technical field [0001] The invention relates to a seed retention method of kohlrabi. Background technique [0002] Kohlrabi is a local variety in Kandun Street, Cixi City, Zhejiang Province. It has been planted for hundreds of years. The leaves are cut and deep, the leaves are thin, the roots are medium, round and smooth, the meat is delicate, and the flavor is good. It is suitable for fresh food to make roasted Kohlrabi. , Loved by consumers. Mosaic rutabaga is a cruciferous crop. When flowering, it is easily pollinated by insects with other cruciferous crops, which leads to biological mixing and variation in traits. The seed retention method of Kohlrabi in the existing traditional technology cannot effectively overcome the above-mentioned variation, and it is difficult to maintain the original characteristics of the farm variety. Summary of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing methods for retaining seeds of kohlrabi, the ...
