Abstract

The invention discloses a seedling raising substrate for selenium-rich rice. The seedling raising substrate comprises a polyethylene seedling raising tray, wherein the interior of the polyethylene seedling raising tray is provided with a barrier plate; a solid seedling raising substrate is laid above the barrier plate; a selenium-rich rice seedling nutrient solution is placed below the barrier plate; the solid seedling raising substrate comprises the following raw materials in parts by mass: 65 to 70 parts of biochar, 18 to 22 parts of ferrous sulfate, 5 to 8 parts of potassium nitrate, 9 to 12 parts of urea and 4 to 7 parts of metronidazole; and the selenium-rich rice seedling nutrient solution comprises the following raw materials in parts by mass: 30 to 35 parts of sodium selenite, 8 to 12 parts of biological corrosive acid, 3 to 6 parts of a microbial antibacterial agent and 70 to 75 parts of water. Thus, the seedling raising substrate provided by the invention adopts the upper-layer solid seedling raising substrate matching with the low-layer selenium-rich nutrient solution, so the content of selenium in cultivated rice seedlings is high, and the rice seedlings are strong and have good quality.

Description

technical field [0001] The invention relates to the field of agricultural organic fertilizers, in particular to a selenium-enriched rice seedling raising substrate. Background technique [0002] Selenium-enriched rice, in addition to retaining all the nutrients of ordinary rice, also has many special health functions such as anti-cancer, anti-cancer, heart protection and anti-aging, anti-oxidation and elimination of free radicals, and improvement of human immunity. Because of the special health care function of selenium-enriched rice and selenium is an essential mineral trace element for the human body, and people's improvement of the quality of life, it has developed rapidly in recent years. The existing seedling-raising substrates do not contain selenium, which cannot meet the seedling-raising requirements of selenium-enriched rice. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a selenium-enriched rice seed...
