Problems solved by technology

At present, in order to produce selenium-enriched strawberries, the method of foliar spraying inorganic selenium is adopted, and its disadvantages are very obvious. First, foliar spraying requires a relatively high content of selenium fertilizer, and high-concentration selenium fertilizer increases the cost of fertilizer use; secondly, because the leaves S...

Embodiment Construction

[0033] The technical scheme of the present invention will be further described below by specific examples:

[0034] Field test location: Qinyi Village, Heqing Town, Pudong New Area, Shanghai, with medium fertility.

[0035] Strawberry varieties for testing: Red Cheek.

[0036] The selenium-enriched seedling raising substrate of the present embodiment is made up of the raw material of following parts by weight:

[0037] 40 parts of industrially decomposed selenium-containing flax cake, 30 parts of decomposed cow dung, 20 parts of rice husk, and 10 parts of river sand were prepared according to the conventional production method of seedling raising substrate.

[0038] The stolon ramet method with simple method and large reproduction coefficient is adopted. The row spacing of the mother plant is 60×120 cm, the number of plants per mu is about 800-100, and the thickness of the seedling substrate is 15 cm.

[0039] In the present embodiment, the selenium-enriched organic and inor...

Abstract

The invention discloses a method for culturing organic selenium-enriched strawberries. The method is characterized in that: flax cakes containing selenium are served as a selenium source for preparing a selenium-enriched growing medium and special selenium-enriched organic and inorganic fertilizers, wherein the selenium-enriched growing medium is used at the strawberry breeding stage, and the special selenium-enriched organic and inorganic fertilizers are used as base fertilizers before the strawberry transplantation, and used as topdressings after the flowering and fruit-bearing stage. According to the invention, the common method that the selenium-containing solution or the selenium-containing foliage fertilizer is mainly sprayed at the flowering and fruit-bearing stage in the current selenium-enriched strawberry production is changed, the unsafe factors existing in the production of the selenium-enriched strawberries are avoided, and the method is economical, effective and pollution-free, and has positive significances in improving the selenium level of crowds and preventing and curing diseases.

Description

[0001] technical field [0002] The invention relates to the technical field of strawberry cultivation, in particular to a method for cultivating organic selenium-enriched strawberries. Background technique [0003] Selenium is an essential trace element for the human body. It is a multifunctional nutrient element for life. It has anti-oxidation, regulates the body's metabolism, improves the body's immunity and disease resistance, improves the reproductive function, resists tumors, and prevents endemic diseases (such as Keshan disease , Kashin-Beck disease), delaying aging, antagonizing toxic elements and other functions. Studies in recent years have shown that selenium is closely related to the structure and function of the cardiovascular system and the occurrence of diseases. Selenium enzyme-glutathione peroxidase has the functions of reducing peroxide, resisting lipid peroxidation and protecting cell membrane. The heart is very sensitive to selenium deficiency. Selenium...
