Preparation method for ecological fertilizer for improving farmland to cultivate selenium-rich vegetables and increase quality of fruits and vegetables

Abstract

The invention discloses a preparation method for an ecological fertilizer for improving farmland to cultivate selenium-rich vegetables and increase quality of fruits and vegetables. The preparation method comprises the following steps: mixing organic substances containing carbon, nitrogen, potassium and phosphorus elements to obtain a mixed material, and adding an enzyme protein to the mixed material, wherein the enzyme protein mainly contains beneficial microorganisms such as bacillus, bifidobacteria, lactic acid bacteria and yeast; putting the mixed material into a fermentation pond containing oxygen, carrying out composting fermentation treatment, carrying out low temperature drying of the mixed material after completion of the fermentation, transferring the material after completion ofthe material into a fermentation bin, adding an additive for improving growth of beneficial bacteria, stirring evenly, and carrying out secondary fermentation; and adding the mixed material after thesecondary fermentation into a granulator, and granulating to obtain the ecological fertilizer. The preparation method for the ecological fertilizer for improving farmland to cultivate selenium-rich vegetables and increase quality of fruits and vegetables can improve the soil micro-ecological environment, provide beneficial conditions for the growth of crops and improve the quality and taste of vegetables.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable planting, and in particular relates to a method for preparing an ecological fertilizer for improving the quality of fruits and vegetables by cultivating selenium-rich vegetables in farmland. Background technique [0002] The fertilizers used for vegetable fertilizers in my country are mainly nitrogen, phosphorus, and potassium. However, with the development of society and economy, the consumption of vegetables is increasing day by day, and vegetables have gradually become one of the indispensable foods in people's daily diet. The industry can provide people with fresh vegetables every day throughout the year, and has developed rapidly. With the development of society and the improvement of people's living standards, people's desire for a pollution-free ecological environment and the demand for green food are getting higher and higher. It has promoted the transformation of traditional agr...

Problems solved by technology

[0003] The existing ecological fertilizers used for organic fruits and vegetables mostly use a combination of organic raw materials and inorganic raw materials to reduce the use of pesticides and chemical fertilizers. However, the current use of ecological fertilizers has no obvious effect and cannot effectively Increase the selenium content in fruits and vegetables, and cannot improve the soil micro-ecological environment for the growth of fruits and vegetables, so that the soil can not be purified better, resulting in a decline in the production quality of fruits and vegetables, and the deterioration of the taste
