Problems solved by technology

[0004] At present, the production of selenium-enriched cucumbers adopts the method of foliar spraying inorganic selenium, which has obvious disadvantages. First, foliar spraying requires a relatively high content of selenium fertilizer, which increases the cost of fertilizer. Secondly, foliar fertilization is easily affected by the environment, and selenium fertilizer is easy If it falls into the field, it will be lost with water and soil. In addition, foliar fertilization will easily lead to excess selenium remaining on the tomato surface, which is toxic and has low safety.
[0005] In addition, the growth of cucumbers requires a loose, fertilizer-retaining, water-retaining and nutrient-complete substrate. Cucumbers require a large amount of fertilizer, and sufficient nutrition should be ensured in each period. Existing chemical fertilizers are used as cucumber planting fertilizers. When the amount is too much, it is easy to cause burning roots or buds; the taste of cucumbers cultivated with chemical fertilizers is poor, and the natural antioxidant components such as glutathione in cucumbers that are beneficial to human health are low, resulting in low nutritional value of cucumbers. It is easy to cause soil compaction and environmental pollution

Abstract

The invention relates to a method for culturing selenium-enrichment and glutathione-enrichment cucumbers. The method includes the steps that 1, when cucumber seedlings are cultured, organic compound fertilizers special for the selenium-enrichment and glutathione-enrichment cucumbers are adopted, the seedling culturing density is 150 to 200 per square meter, and the applied fertilizer quantity ranges from 8 kg per mu to 10 kg per mu; 2, the seedlings which are obtained in the first step of seedling culturing and each have three to four main leaves are planted, and before the seedlings are planted, organic compound fertilizers special for the selenium-enrichment and glutathione-enrichment cucumbers are applied to culturing land, and after the fertilizers are applied, the land is turned over and leveled, wherein the applying quantity ranges from 150 kg per mu to 200 kg per mu, when planting is carried out, the planting distance ranges from 50 cm to 60 cm, and double-line culturing is carried out; 3, plants are adjusted; 4, additional fertilizing is carried out, wherein when fruits begin to be borne, organic compound fertilizers special for the selenium-enrichment and glutathione-enrichment cucumbers are additionally applied, and the additionally-applying quantity ranges from 100 kg per mu to 150 kg per mu; 5, harvesting is carried out. According to the method, sufficient glutathione synthesis precursors and sufficient selenium sources are provided for the cucumbers from the seedling culturing stage, the cucumbers can absorb nutrition from the land in the whole growing period and convert the nutrition into glutathione and organic selenium through photosynthesis, and the content of the glutathione and the content of the organic selenium in the cucumbers are high.

Description

technical field [0001] The invention relates to a cultivation method for selenium-rich and glutathione-rich cucumbers, belonging to the technical field of cucumber cultivation. Background technique [0002] At present, chemical fertilizers are still commonly used in agricultural production in my country. Single application of chemical fertilizers cannot meet the needs of crop growth, which limits the development of agriculture. Long-term use of large amounts of chemical fertilizers will cause soil compaction, soil quality continues to deteriorate, soil fertility declines, and the quality of agricultural products declines. , in order to meet the fertilizer efficiency, the application of chemical fertilizers has increased, but the absorption and utilization of chemical fertilizers is limited, and a large amount of chemical fertilizer residues also cause serious pollution to soil and water sources. [0003] Selenium is an essential trace element for the human body. It is a multi...
