Planting method capable of reducing root rot of Panax notoginseng under conditions of microspray irrigation and fertilization

Abstract

The invention relates to a planting method capable of reducing the root rot of Panax notoginseng under the conditions of microspray irrigation and fertilization, and belongs to the technical field ofcultivation of Panax notoginseng. The planting method capable of reducing the root rot of Panax notoginseng under the conditions of microspray irrigation and fertilization includes the following steps: site selection and land preparation, ridge forming, water and fertilizer integrated device installation, seedling selecting and transplanting, field, water and fertilizer management and digging andharvest. The planting method is scientific and reasonable, and fertilization is performed in stages by adopting a water and fertilizer integration technology according to demands and the law of fertilizer demands in different growth stages of Panax notoginseng, so that fertilizer and water and labor are saved; rain shading treatment is conducted on Panax notoginseng in the rainy season so that thehumidity of air and soil and the incidence of the root rot of Panax notoginseng are reduced; effects of heat preservation and cold and moist resistance to temperature drop can be achieved by a movable rainshed in winter, and the disease resistance of Panax notoginseng can be improved thorough salt treatment on Panax notoginseng; and through the method, growth and development of Panax notoginsengcan be promoted effectively, the incidence of the root rot of Panax notoginseng is reduced, and the purposes of quality improvement and yield increase are achieved.

Description

technical field [0001] The invention relates to a planting method for reducing root rot of Panax notoginseng under the condition of micro-spray irrigation and fertilization, and belongs to the technical field of Panax notoginseng planting. Background technique [0002] Panax notoginseng (Panax notoginseng) is a perennial herb of Araliaceae genus Ginseng, which is a traditional precious Chinese medicinal material in my country. It has the effects of promoting blood circulation, removing blood stasis, nourishing blood, protecting myocardium, anti-arrhythmia, lowering blood fat, lowering blood pressure, protecting brain tissue, improving cerebral blood circulation, protecting liver, and enhancing immunity. At present, there are the following problems in the cultivation of Panax notoginseng: (1) The amount of fertilization, shading, and irrigation is vague, and there is no clear range of quantities.

AI Technical Summary

Problems solved by technology

At present, there are the following problems in the cultivation of Panax notoginseng: (1) The amount of fertilization, shading, and irrigation is vague, and there is no clear range of quantities. The planters mostly rely on experience for irrigation, fertilization, and shading, so there is a blindness of more fertilization and more irrigation The field management mode causes a lot of waste of water resources and abuse of fertilizers; the abuse of fertilizers can easily cause soil compaction, hinder the absorption of nutrients by crops, and damage the soil environment; (2) Panax notoginseng root rot, dead leaf disease and a series of serious diseases The cultivation of Panax notoginseng is troubled, so farmers use a lot of pesticides, resulting in excessive pesticide residues in Panax notoginseng

Long-term use of pesticides will easily cause bacteria or parasites to develop resistance, and the effect of pest control will not be achieved; (3) Seedlings have not been specially domesticated, resulting in low survival rate of transplanting, low disease resistance, and affecting The yield and quality of Panax notoginseng; (4) Intensive rainfall in the rainy season, resulting in high air and soil humidity, the growth of fungi and bacteria in the soil, resulting in a high incidence of root rot of Panax notoginseng; (5) In recent years, Yunnan has encountered cold waves many times in winter During the cold wave, the temperature dropped sharply, Panax notoginseng could not adapt to the low temperature environment, and a large area died, which brought heavy economic losses to the Panax notoginseng growers
