Preparation method of dendrobium officinale culture medium

Abstract

The invention relates to the technical field of preparation of plant culture media, and in particular relates to a preparation method of a dendrobium officinale culture medium. The culture medium consists of peanut shells, saw dust, river sand, peanut bran and microbial strains. The method comprises the following steps of: first, fermenting the peanut shells, the saw dust and the peanut bran by the microbial strains to obtain biofertilizer; and then, mixing and uniformly stirring the biofertilizer and the river sand to form the culture medium for production. The sand river applied in the method is better in water retention, and thus water management of the medium is over less than half of conventional water management in production. The peanut shells are large in size, and thus the medium is loose and good in ventilation. The peanut shells are hard and not easy to rot, and nutrients are converted slowly, so that a long-acting and balanced nutrient supply system is formed. Meanwhile, the medium is loosened in texture to promote growth of multiple root systems of dendrobium officinale, so that the growing speed and the yield of dendrobium officinale are improved. The method is beneficial to large-scale and intensive artificial cultivation of dendrobium officinale in plants.
