The invention discloses a
nutrient solution for secondary
grafting of poria cocos as well as a preparation method and application of the
nutrient solution, and relates to the technical field of poria cocos planting. The method comprises the following steps: mixing plain boiled water, white
sugar, edible white vinegar,
fresh milk,
moroxydine,
dinotefuran, table salt and
monopotassium phosphate, uniformly shaking to prepare a
nutrient solution for secondary
grafting of poria cocos, and filling the
nutrient solution into a closed container for later use. The method comprises the following steps: soaking small blocks of fresh poria cocos
sclerotium to be subjected to secondary
grafting in a
nutrient solution by hands, attaching the small blocks of the fresh poria cocos
sclerotium to the scraped basswood grafting position, and covering with surface soil. The yield of the poria cocos is obviously increased through secondary grafting. In the process, proper carbon and
nitrogen elements are provided through white
sugar and
fresh milk; the salt and the
monopotassium phosphate provide
sodium,
phosphorus and
potassium elements; the white vinegar, the viroxydine and the
dinotefuran have the effects of disinfection,
disease prevention and
insect prevention respectively; under the synergistic effect of the raw materials, reasonable supplementation of exogenous nutrients of pine trees is guaranteed, and with the assistance of soil
moisture and
nutrition, the purposes of harvesting 20-30 days in advance and achieving high-quality, high-yield and efficient cultivation production are achieved.
