Planting substrate for dendrobium officinale and preparation method for planting substrate

Abstract

The invention discloses a planting substrate for dendrobium officinale. The planting substrate comprises a substrate A, a substrate B and a substrate C which are arranged in a manner of being superposed sequentially from bottom to top, wherein the substrate A is prepared from 10-20 parts (by weight) of dried rice straws or dried sugarcane leaves; the substrate B is prepared from 5-20 parts (by weight) of medium sand, 10-30 parts (by weight) of edible fungus leftovers, and the like; and the substrate C is prepared from 15-45 parts (by weight) of biocarbon, 15-45 parts (by weight) of semi-corroded miscellaneous tree branches, 15-45 parts (by weight) of tung fruit peels, 15-45 parts (by weight) of corncobs, 15-45 parts (by weight) of pine barks, and the like. A preparation method for the planting substrate comprises the steps of preparing the biocarbon, preparing the substrate A, the substrate B and the substrate C and then carrying out superposition. The preparation method for the planting substrate is simple and easy to understand; and the planting substrate prepared by the preparation method has the advantages that the condition that the substrate is rotted, is air-proof and does not hold moisture in long-term use is overcome, the cost is low, the nutrition is complete, the growth of the dendrobium officinale is better facilitated, dendrobium officinale stems are promoted to grow more sturdy, and dendrobium officinale root systems are promoted to be more developed.

Problems solved by technology

Water moss can be used after simple washing and sterilization, but its price is relatively high, which leads to an increase in the cost of planting and production, which is unacceptable to most growers. Compared with sphagnum moss, wood chips have obvious advantages in price, but Sawdust needs to be fermented before use, and it is easy to rot during the planting process and needs to be replaced, requiring a lot of manpower and material resources
