Problems solved by technology

However, different plants have different tolerances to the trace element selenium. Excessive injection of selenium into plants or improper injection methods will cause selenium to accumulate in plants, inhibit plant growth, cause toxicity, and waste precious selenium resources. increase production costs

Embodiment 1

[0019] Embodiment one: spraying

[0020] When applying the nutrient solution of the present invention, the nutrient solution is diluted 40 times at the flowering stage; the nutrient solution is diluted 30 times at the young fruit stage; the nutrient solution is diluted 20 times at the green fruit stage; 20 times, the interval of each spraying is 1 month, and the amount of spraying is based on the wetness of the leaves of pear flowers and pear trees.

[0021] The selenium-enriched pear produced by the method of the invention is tested by the Fruit and Seedling Quality Supervision, Inspection and Testing Center (Zhengzhou) of the Ministry of Agriculture, and the selenium content reaches 50-60ug / kg, and the selenium content of the control is 1.5ug / kg.

[0022] The physical and chemical indexes of the selenium-enriched pear produced by the method of the present invention are tested by the Fruit and Seedling Quality Supervision, Inspection and Testing Center (Zhengzhou) of the Mini...

Embodiment 2

[0023] Embodiment two: instillation

[0024] Drill a slanted hole on the main trunk of the pear tree. The slanted hole is slanted downward, forming an included angle of 45° with the horizontal direction, and the depth is 5mm. Inject the selenium nutrient solution into the inclined hole 3 times a year. The nutrient solution is packed in a hanging water bottle and hung on the branches. In the green fruit stage, the interval between each infusion is 30 days, the volume of each infusion is 250ml, and the infusion speed is controlled so that the nutrient solution in the inclined hole does not overflow.

[0025] The selenium content of the selenium-enriched pear produced by the method of the invention can reach 35-50 ug / kg, and the selenium content of the control is 1.5 ug / kg.

Abstract

A method for producing Se-enriched pear is characterized by that Se-contained nutritive liquid is sprayed onto pear flowers and leaves or injected in the trunk of pear tree at different growth phases. Its advantages are high Se content in pear (30-60 micrograms / kg), low cost and high utilization rate of Se.

Description

Technical field [0001] The invention relates to a production method of fruits rich in trace elements, in particular to a production method of selenium-rich pears. Background technique [0002] Modern science has proved that selenium is an essential trace element for humans and animals to maintain normal physiological functions. Humans and animals usually consume various crops to obtain the required trace elements. A lack of selenium in humans and animals can cause many diseases. In selenium-deficient areas, due to the extremely low selenium content of crops, it will lead to insufficient intake of trace elements for humans or animals; in severe selenium-deficient areas, it will also cause human Keshan disease, Kaschin-Beck disease and white muscle disease of poultry and livestock, etc. Endemic. According to reports, it is internationally recognized that more than 2 / 3 of my country's areas are selenium-deficient areas, and nearly 1 / 3 of them are severely selenium-deficient ar...
