Nutritionally-balanced selenium-rich nutrient solution for cultivating chillies

Abstract

The invention provides a nutritionally-balanced selenium-rich nutrient solution for cultivating chillies. The nutrient solution is prepared from the following raw materials in parts by weight: 0.002 to 0.008 part of urea, 0.05 to 0.1 part of calcium nitrate, 0.1 to 1 part of potassium nitrate, 0.1 to 1 part of magnesium sulfate, 0.001 to 0.005 part of zinc sulfate, 0.005 to 0.01 part of sodium molybdate, 1 to 3 parts of ammonium phosphate, 0.005 to 0.05 part of ferric chloride, 0.001 to 0.005 part of ammonium dihydrogen phosphate, 0.1 to 1 part of potassium iodide, 1 to 5 parts of glucose, 0.1 to 0.5 part of sodium tetraborate, 0.1 to 0.5 part of calcium superphosphate, 0.001 to 0.01 part of copper sulfate, 0.5 to 1 part of organic acid, 0.1 to 1 part of vitamin B, 0.05 to 0.1 part of vitamin C, 0.5 to 5 parts of sodium selenite and 5000 to 7000 parts of water. By reasonably matching the raw materials in a nutrition balancing manner, the growth of the chillies is promoted effectively. Tests prove that the stem height, the survival rate, the yield and the selenium content of the chillies cultivated in the nutrient solution are improved.

Description

technical field [0001] The invention provides a plant nutrient solution, in particular to a nutritionally balanced selenium-enriched nutrient solution for pepper cultivation. Background technique [0002] Nutrients play an important role in the normal growth and development of plants. When preparing the nutrient solution, the formula and dosage should be determined according to different plants and different growth periods. A nutritionally balanced nutrient solution is conducive to plant absorption and utilization. [0003] Selenium is an essential trace element for the human body, which has biological properties such as anti-cancer, anti-aging, and improving human immunity. The Chinese Nutrition Society recommends a per capita daily selenium intake of 50-250 mg, but currently the daily selenium intake of adults in my country is only 26-32 mg, which is seriously insufficient. [0004] Pepper is one of the vegetables commonly used by people. By increasing the selenium conte...
