Embodiment 1

[0058] Planting spring and autumn greenhouse cucumbers

[0059] The soil was sterilized and disinfected one month before the cucumber was planted, followed by deep ploughing and rotary tillage, and 3 tons of organic fertilizer and 50 kg of compound fertilizer (N-P 2 O 5 -k 2O: 15-22-8). The soil moisture sensor 8 is pre-embedded in the soil. The pipe-laying and film-covering integrated machine is used for pipe-laying, the ridge-raising and fertilizing machine is used for ridge-raising and general application of base fertilizer. The ridge adopts an isosceles trapezoid section, the height of the ridge is 20cm, the width of the ridge surface is 70cm, the spacing between the center lines of the ridge is 160cm, the wide row spacing of cucumbers is 90cm, the narrow row spacing is 60cm, and the fixed plant spacing is 30cm, such as image 3 shown.

[0060] Using underground drip irrigation technology, the drip irrigation belt is cast type, the flow rate is 1.6L / h, the wall thickn...

Abstract

The invention belongs to the technical field of agricultural fruit and vegetable cultivation and in particular relates to a subsurface drip irrigation cultivation method for selenium-enriched melons and vegetables. According to the method, selenium application is performed in a manner of combining drip application and foliar application, and sustainable selenium application is realized according to an ideal water, fertilizer, gas selenium regulation body in soil of a crop root region by utilizing an oxygenated selenium-enriched drip irrigation precision control system. According to the system,automated oxygenated selenium-enriched drip irrigation of multiple melon varieties can be realized by a programmable logic controller, synergistic improvement of the crop yield, selenium content andfruit nutrition quality is realized, and the utilization efficiency of inorganic selenium fertilizers is improved. Moreover, the method disclosed by the invention has the advantages that the labor force is saved, and the production efficiency and production quality can be improved.

Description

technical field [0001] The invention belongs to the technical field of selenium-enriched cultivation of agricultural fruits and vegetables, in particular to an underground drip irrigation cultivation method of selenium-enriched melons and vegetables. Background technique [0002] Selenium is an essential component of glutathione peroxidase (GPX), which can regulate and protect body tissues and organs against oxidative stress, immune function, and growth and development. Kashin-Beck disease, cardiovascular disease, anti-aging, relieve heavy metal toxicity and other effects. In 1973, the World Health Organization declared selenium to be an essential trace element in animal life. In 1988, the Chinese Nutrition Society also listed selenium as one of the 15 essential nutrients for the human body, and stipulated that the RDA value (recommended daily intake of human body) of selenium was 50 μg. In my country, 72% of the counties are low selenium or selenium deficient areas. A nu...
