How to prevent diseases and apply fertilizer for Atractylodes macrocephala? Please provide an introduction to the methods.The common diseases of Atractylodes macrocephala are root rot and southern blight, and the control methods are as follows:
Carefully select seedlings: They should be free of pests and diseases, with plump apical buds, slender upper parts, round and large lower ends, fine and tender skin, and dense soft fine roots.
Seed soaking disinfection and soil sterilization:The planting material and soil are the main sources of the pathogens of root rot and southern blight in Atractylodes macrocephala. Therefore, the work of disinfecting the planting material and sterilizing the soil must be done well. For seed soaking sterilization, 4000-fold dilution of Lvxiang No. 1 (hymexazol; Lvjia 198 is the same pesticide), 500-fold dilution of carbendazim, and thiophanate-methyl and other solutions can be used; for soil sterilization, 3000-fold dilution of Lvxiang No. 1, 1500-fold dilution of Lvxiang No. 2, or 2 kg of dexon mixed with 50 kg of fine soil can be used for bed surface disinfection treatment.
Fertilization methods for Atractylodes macrocephala:Atractylodes macrocephala has a long growth period and requires large amounts of nitrogen, phosphorus, and potassium fertilizers, and is especially very sensitive to potassium fertilizer, requiring 20 kg of potassium chloride per mu. The fertilization principle is "apply sufficient basal fertilizer, apply seedling fertilizer early, apply heavy fertilizer at the bud-picking stage, and skillfully apply foliar topdressing." The basal fertilizer should be mainly organic fertilizer, with a certain amount of phosphorus and potassium fertilizer; the bud-picking fertilizer should be mainly nitrogen fertilizer. Zinc is a trace element necessary for the growth and development of Atractylodes macrocephala. Applying zinc can not only significantly increase the yield of Atractylodes macrocephala but also improve its quality. For basal application, apply 1-2 kg of zinc sulfate per mu, broadcast together with land preparation; for foliar spraying, use a 0.5-1% zinc sulfate solution and spray it on the leaves 2-4 times after the seedlings of Atractylodes macrocephala have emerged uniformly.
