Method for planting gastrodia elata by utilizing old mycelia colonized woodlogs

Abstract

The invention discloses a method for planting gastrodia elata by utilizing old mycelia colonized woodlogs. The method comprises the following steps: 1) selecting the old mycelia colonized woodlogs: selecting the old mycelia colonized woodlogs having a thicker wood layer, no mildew and no black spots, wherein the gastrodia elata is cultivated in the old mycelia colonized woodlogs before; 2) diggingpits: digging a long pit with a depth of 40-45 cm and a width of 40-50 cm before the gastrodia elata is planted; 3) putting the old mycelia colonized woodlogs: putting the prepared old mycelia colonized woodlogs in the bottom layers of the pits, sprinkling saw dust with a thickness of 1 cm and a small amount of armillaria mellea strains on the old mycelia colonized woodlogs, sprinkling water forwetting, and covering the pits with new soil for 5-10 cm; and 4) performing planting: putting new mycelia colonized woodlogs and gastrodia elata seeds on the new soil layer of the old mycelia colonized woodlogs, and performing covering by using surface layer soil with a thickness of 10 cm. According to the method for planting the gastrodia elata by utilizing the old mycelia colonized woodlogs disclosed by the invention, the old mycelia colonized woodlogs are selected and processed and placed in the bottom layers for accompanying planting with the gastrodia elata, the characteristic that armillaria mellea rhizomorph grows upwards is utilized to separate bacteria on the old mycelia colonized woodlogs from the new mycelia colonized woodlogs and the gastrodia elata seeds, and therefore the method achieves the effects of utilizing the old mycelia colonized woodlogs and increasing a yield and increasing efficiency.

Description

technical field [0001] The invention relates to the fields of agriculture and Chinese herbal medicine planting, in particular to a method for planting Gastrodia elata with old materials. Background technique [0002] Gastrodia elata, also known as Chijian, is a perennial herb of the genus Gastrodia genus in the family Orchidaceae, with thick rhizomes, no green leaves, obovate oval capsules, often propagated by tubers or seeds, and its rhizomes are used as medicine to treat dizziness and numbness of limbs , convulsions in children and other diseases, it is a valuable traditional Chinese medicine. Due to the high medicinal value of gastrodia elata, the market demand is huge, especially the gastrodia elata produced in Guizhou has a high content of active ingredients, and the supply has been in short supply. [0003] Gastrodia elata has no roots and leaves, and cannot carry out photosynthesis. It can only rely on Armillaria armillaria to supply nutrients for growth and reproduc...

Problems solved by technology

During the planting process of gastrodia elata, the old fungi will be infected with microorganisms such as bacteria and viruses. Reusing gastrodia elata cultivation may lead to a decrease in production. It is a pity to throw them away, which has always troubled the vast number of gastrodia elata growers.
