Abstract

The invention discloses a planting method of a selenium-enriched pear, which comprises the following steps of outwards digging 2 to 4 radial ditches at positions which are 0.3m to 0.5m away from a trunk, wherein the depths of the ditches are 45cm to 50cm; the widths of the ditches are 25cm to 35cm; the lengths of the ditches are 1m to 1.5m; during the middle ten days of April each year, sprinkling selenium-enriched fertilizer with thicknesses of 2cm to 5cm in the ditches, then filling the selenium-enriched fertilizer with selenium-enriched mixed matrixes with the thicknesses of 10cm to 15cm, covering and filling selenium-enriched mixed matrixes with soil and the height of the soil is lower the ground, finally carrying out irrigation, and carrying out mulching; in a summer-drought season, at positions which is 20cm to 25cm away from the trunk, placing 3 to 5 water bags filled with 30kg to 40kg of selenium-enriched water, and pricking holes at the bottoms of the bags. According to a planting technique of the selenium-enriched pear, which is provided by the invention, a scientific and reasonable method for applying selenium fertilizer is adopted; the utilization rate of the selenium fertilizer is high; the conversion ratio of a selenium element in a pear tree is high; the use level of the selenium fertilizer is effectively decreased; and the planting cost is decreased.

Description

technical field [0001] The invention belongs to the field of fruit tree planting, and in particular relates to a planting method of selenium-enriched pears. Background technique [0002] Selenium is one of the 14 essential trace elements currently known in humans and animals. All cells and tissues of humans and animals contain selenium. Selenium often cooperates with various trace elements, proteins and vitamins in the body to complete and exert its physiological and nutritional functions. In terms of human growth and reproduction, selenium has a similar effect to vitamin E, and can strengthen the role of vitamin E, prevent cell membrane degeneration, maintain tissue elasticity, delay the oxidation of unsaturated fatty acids, and prevent early aging. The antioxidant capacity of selenium is 500 times higher than that of vitamin E, and each selenium atom can roughly replace 700-1000 molecules of vitamin E. Selenium and vitamin E work together to protect cell membranes, but t...
