A method for prepare a mixed substrate for soilless culture of vegetables

The invention discloses a preparation method of a mixed substrate used for soilless culture of vegetables, in particular comprising the following steps: determining the physical and chemical properties of a single substrate; Establishment of Regression Equation for Physical and Chemical Properties of Mixed Matrix; The proportion of mixed matrix was determined by regression equation. The adjustmentof EC value and pH value of mixed substrate; Substrate Subsequent Management. The method of the invention can determine mixed ingredients under different conditions according to different kinds of single substrate or different cultivated vegetable varieties, and the mixed substrate can effectively improve the yield and quality of soilless culture vegetables, so as to be popularized and applied inproduction. 本发明公开了种蔬菜无土栽培所用混配基质的配制方法，具体包括以下步骤：单基质理化性质的测定；混配基质理化性质回归方程的建立；通过回归方程确定混配基质的配比；混配基质EC值、pH值的调节；基质后续管理。本发明的方法可以依据单基质种类的不同或种植蔬菜品种的不同，确定不同情况下的混配成分，混配后的基质可以有效提高无土栽培蔬菜产量和质量，进而在生产中推广应用。
