Abstract

The invention discloses a nano-selenium containing soilless culture matrix and a preparation method thereof. The nano-selenium containing soilless culture matrix provided by the invention includes animal urine, crop straw, industrial and agricultural by-products, selenium dioxide, manufactured sand and other raw materials. Through mixing and fermentation of the animal urine, crop straw, industrial and agricultural by-products, and selenium dioxide, a nano-selenium containing decomposed organic matter can be obtained, and the decomposed organic matter and the manufactured sand are mixed to prepare the nano-selenium containing soilless culture matrix.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a soilless cultivation substrate containing nano-selenium and a preparation method thereof. Background technique [0002] my country is facing severe challenges from population growth and land reduction. The population accounts for 1 / 4 of the world's total population, but its arable land area is only 1 / 7 of the world's total arable land area. According to statistics in 2000, the national per capita arable land is only 0.01 hm2, soilless cultivation can provide several times or even more than ten times the quantity of products than ordinary soil cultivation, and can use sandy beaches, saline-alkali and other barren lands to produce agricultural products, laying a solid foundation for the food safety guarantee system. my country is a country with very poor water quality resources, and is listed as one of the 13 water-poor countries in the world. The per capi...
