Chromium and glutathione-rich cucumber cultivation method

Abstract

The invention relates to a chromium and glutathione-rich cucumber cultivation method comprising steps of (1) applying chromium and glutathione-rich cucumber specific organic composite fertilizer during cucumber seedling nursing stage, (2) fixed-planting seedlings having three to four main leaves and acquired in the step (1), (3) adjusting plants, (4) dressing fertilizers and (5) harvesting. In the step (1), the seedling nursing density is 150 to 200 plants per square meter and 8 to 10kg fertilizer is applied for per mu; in the step (2), after fertilizer application, the soil is turned over and flattened; plant distance is 50 to 60cm during fixed plantation and the plants are cultivated in double lines; in the step (4), chromium and glutathione-rich cucumber specific organic composite fertilizer is dressed when the seedlings bear fruits and the dressing amount is 100 to 150kg per mu. Enough glutathione compound precursor and chromium source can be provided during cucumber seedling nursing phase; cucumbers can absorb the glutathione compound precursor and chromium source from the soil during the whole growth period and converts the glutathione compound precursor and chromium source into glutathione and organic chromium; and the cucumber has high content of glutathione and organic chromium.

Description

technical field [0001] The invention relates to a cultivation method for chromium-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] With the continuous improvement of people's living standards, the intake...

Problems solved by technology

[0004] At present, the method of foliar spraying inorganic chromium is adopted to produce chromium-rich cucumbers, which has obvious disadvantages. Firstly, foliar spraying requires relatively high chromium fertilizer content, which increases the cost of fertilizer. Secondly, foliar fertilization is easily affected by the environment, and chromium fertilizer is easy to When it falls into the field, it will be lost with water and soil. In addition, foliar fertilization will easily lead to excess electrodeless chromium 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
