Description

Special organic fertilizer for dendrobium nobile as well as preparation method and application thereof Technical Field The invention relates to the technical field of fertilizers, in particular to a special organic fertilizer for dendrobium nobile, and a preparation method and application thereof. Background The dendrobium is a perennial epiphyte of dendrobium of Orchidaceae, and has the advantages of loose and breathable property, high organic matter content, water and fertilizer conservation. The conventional organic fertilizer has the following defects: (1) The pH is higher, the air permeability is poor, and the root rot and the high disease occurrence of the dendrobium are easy to cause; (2) The nutrient release is too fast, the roots are easy to burn, the growth vigor is weak and the effective components are low when the release is too slow; (3) The lack of the medium trace elements of the adaptive dendrobium has limited improvement of yield and quality; (4) The fermentation is incomplete, contains ova and pathogenic bacteria, and influences the organic planting standard.
