Method for cultivating radix notoginseng without pesticide residues

Abstract

The invention provides a method for cultivating radix notoginseng without pesticide residues so as to solve the defects in the prior art. The method comprises the following steps: S1, selecting a land; S2, building a cultivation greenhouse; S3, transplanting seeds and seedlings; and S4, performing seed and seedling management, wherein the cultivation greenhouse in the step S2 is a planting greenhouse with a shading net and a rain-sheltering film; the seed and seedling management in the step S4 comprises plant disease and insect pest prevention and control, and fertilization management; the plant disease and insect pest prevention and control comprises: preventing and controlling the epidemic diseases of the radix notoginseng by a method for paving the rain-sheltering film to isolate the radix notoginseng in the planting greenhouse from contacting rainwater, and preventing and controlling the insect pests by sunning the land for at least one month before building the cultivation greenhouse and by cooperatively using an insect-attracting board and / or poison bait; the fertilization management comprises fertilizer preparation and fertilization; and the fertilizer preparation comprises preparation by using homemade fertilizer and / or preparation by using commercial fertilizer. By the cultivation method provided by the invention, high-quality radix notoginseng products with zero pesticide residue quantity can be obtained, the plant disease morbidity of the radix notoginseng is reduced to be below 10%, and the insect pest morbidity is reduced to be 20% to 30%.

Description

Problems solved by technology

[0003] Panax notoginseng is warm and humid in nature, and it is easy to induce a variety of diseases and insect pests. Its cultivation and management require a high level of technology. The procedural use of Panax notoginseng makes the quality and safety of Panax notoginseng particularly prominent. At present, the prevention and control of diseases mainly relies on chemical pesticides. The components of the pesticides used for prevention and control cover almost all the current types of chemical pesticide components. Become the key factor restricting the development of Panax notoginseng industry in the future
