A kind of method for disinfection of Panax notoginseng planting soil

Abstract

The invention discloses a panax notoginseng planting soil disinfecting method. Steam pipelines are reasonably arranged through input of high-temperature steam in a steam boiler, panax notoginseng planting soil is disinfected under a high temperature through a movable steam metal pipe frame to kill a large number of harmful bacteria in the soil, harmful substances generated in the panax notoginseng planting process are subjected to degradation, panax notoginseng successive cropping obstacles are broken through, panax notoginseng diseases can be obviously reduced, less or no pesticide is needed, so that panax notoginseng quality is guaranteed. Under the condition of reasonably adding organic fertilizer, panax notoginseng planting can be carried out on the same cultivated land continuously a plurality of times, other new panax notoginseng planting land is not needed, panax notoginseng land supplement and demand contradictions can be avoided, panax notoginseng fundamental and standard planting is facilitated, and a panax notoginseng GAP planting foundation is formed. The method is easy to implement and practical, factory-like panax notoginseng planting is facilitated, panax notoginseng quality is guaranteed, the ecological environment is protected, and obvious economical, social and ecological benefits are achieved.

Description

technical field [0001] The invention relates to a method for disinfecting planting soil, in particular to a method for disinfecting notoginseng planting soil. Background technique [0002] Panax notoginseng is a traditional Chinese medicinal material with a history of more than 700 years of medicinal use in my country. It is the most distinctive large variety of Chinese medicinal materials in Southwest China and has significant curative effects in the treatment of cardiovascular and cerebrovascular diseases. The obstacle of continuous cropping in the process of Panax notoginseng planting is very prominent. Because Panax notoginseng is single-planted on a large scale year after year, and Panax notoginseng is a perennial herbaceous plant that likes a warm and humid environment, the loss caused by various diseases in the cultivation of Panax notoginseng can reach 30%-40% all the year round, and it can reach more than 80% in severe cases. Among them, the perennial incidence rat...

Problems solved by technology

[0003] The existence of obstacles to continuous cropping of Panax notoginseng makes traditional Panax notoginseng planting need to constantly find new planting land, making it difficult to establish a fixed planting base, and due to the increasingly prominent contradiction between supply and demand of Panax notoginseng planting land, the land suitable for Panax notoginseng planting in the origin of Panax notoginseng Less and less, resulting in the gradual spread of Panax notoginseng cultivation from suitable areas to sub-suitable areas, affecting the medicinal effect of Panax notoginseng and the protection of origin, and affecting the construction of the Sanqi GAP base; traditional Panax notoginseng planting diseases are serious, and disease control A large amount of pesticides are required in the process. According to statistics, there are more than 130 types of pesticides used in the cultivation of Panax notoginseng all year round. In summer and autumn when diseases occur more often, pesticides are sprayed every 3 to 5 days, and more than 10 pesticides are mixed each time. kind

Excessive application of pesticides has resulted in excessive pesticide residues in products, seriously affecting the quality of Panax notoginseng, causing the overall export of Panax notoginseng to drop from nearly 100 million yuan to less than 40 million yuan at present, and it is showing a continuous downward trend
