Cultivation method of pollution-free red-skin red-heart radishes with high anthocyanin content

Abstract

The invention discloses a cultivation method of pollution-free red-skin red heart radishes with high anthocyanin content. The cultivation method comprises the following steps: (1) selecting a land, preparing the land, hitting holes, (2) seeding, watering, (3.1) thinning seedlings, finally singling the seedlings, (3.2) topdressing for multiple times, (4) spraying fertilizer on leaves for multiple times, (5.1) preventing and curing downy mildew and soft rot, (5.2) preventing and curing stripedflea-beetles, aphids and cabbage caterpillars, and (6) harvesting the radishes. When the cultivation method is adopted to cultivate the pollution-free red-skin red heart radishes with the high anthocyanin content, loose and ventilating soil environment required by root growth can be effectively ensured, growth of roots is prompted, the roots are enabled to be stronger, plant growth is prompted, meanwhile perfect stem and leaves are effectively prompted through the fertilizer spraying on the leaves, photosynthesis efficiency is improved, synthesis of protein, sugars, vitamins and anthocyanin is prompted, stress resistance, plant disease resistant capacity and inspect pest resistant capacity of the crop are strengthened, the anthocyanin content of fleshy roots of the red-skin red heart radishes is improved, yield of the red-skin red heart radishes is improved by 25% to 28%, and the anthocyanin content is improved by 8% to 10%.

Description

technical field [0001] The invention relates to a method for cultivating radishes, in particular to a method for cultivating red-skinned red-hearted radishes with high anthocyanin content, and belongs to the technical field of plant cultivation. Background technique [0002] Red-skinned red-heart radish has a wide range of sources, low price and stable anthocyanins, which is very competitive in the market. The price of anthocyanins from different sources in the international market in 2012 was US$500-1400 / kg. Anthocyanins are mainly produced in South America, Europe, America, Asia and other places. South America mainly produces anthocyanins from purple corn; Europe uses grapes, elderberries, blueberries, gooseberries, wild cherries and other fruits as raw materials. Relatively expensive; my country mainly uses raw materials such as radishes and grapes, and radish anthocyanins have received great attention due to their excellent stability. But so far, the yield per mu of re...

But so far, the yield per mu of red-skinned red radish is about 1800-2000kg / 667㎡, which is generally not high, and the anthocyanin content is about 160mg / 100g fresh weight; at the same time, the pollution-free red-skinned red radish products account for The proportion of red-skinned red-heart radish is very small, and the prior art lacks an advanced, practical and standardized red-skinned red-heart radish cultivation method
