Abstract

The invention discloses a spinach culture medium as well as a preparation method and an application thereof. The spinach culture medium comprises vinegar residues and seaweed slags. The spinach culture medium disclosed by the invention has the advantages that by using industrial and agricultural wastes, a soilless culture medium is produced through high-temperature fermentation, thereby turning waste into wealth and turning the harm into benefits. The spinach culture medium has the characteristics of sufficient nutrition, good water absorption and ventilation property, moisture and fertilizer conservation and moderate volume-weight, and pH and EC (Electrical Conductivity) values suitable for growth of spinach, and can be used for effectively improving the dry and fresh weight of the overground part of spinach, remarkably reducing the contents of nitrate and nitrite in blades, improving the contents of soluble proteins and organic acids and improving the quality of spinach.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a spinach cultivation substrate and its preparation method and application. The cultivation substrate is used to reduce the accumulation of nitrate in spinach. Background technique [0002] With the progress of the society and the development of the economy, the quality requirements for vegetable products are getting higher and higher. The traditional cultivation methods use a lot of chemical drugs such as fertilizers and pesticides, and the cultivation system is unreasonable, which leads to the deterioration of soil properties and the cultivation quality. Decline, especially the excessive accumulation of nitrate and nitrite in vegetable products. This kind of vegetables can cause methemoglobinemia, which can combine with secondary amines in the human body to form nitrosamines, which are easy to cause cancer, and are now receiving more and more attention. Wi...
