Method for improving continuous cropping soil of panax notoginseng

Abstract

The invention discloses a method for improving the continuous cropping soil of panax notoginseng, which comprises the following steps: (1) installing a drip irrigation device; (2) fumigating and disinfecting soil with dazomet; (3) disinfecting soil with chlorine dioxide; and (4) adding a compound microbial fertilizer. As a fumigant for the continuous cropping soil of panax notoginseng, dazomet cankill fungi, bacteria, insects and other organisms in the soil and is low-toxicity and safe. Chlorine dioxide can kill bacterial propagules, bacterial spores, fungi, mycobacteria and viruses, and bacteria will not develop resistance to chlorine dioxide. The compound microbial fertilizer can improve the yield of panax notoginseng, improve the quality of panax notoginseng, reduce the use of chemicalfertilizer, lower the cost, improve the soil and protect the ecological environment. By using the method, the seedling emergence rate of panax notoginseng seeds in the continuous cropping soil can bemore than 95%, the seedling survival rate can be more than 90%, and the disease incidence can be reduced.

Description

technical field [0001] The invention relates to the field of agricultural plant protection, in particular to a soil disinfection method for continuous cropping of notoginseng. Background technique [0002] Panax notoginseng, the name of traditional Chinese medicine. It is the dry root and rhizome of Panax notoginseng of Araliaceae. Excavate before the flowers bloom in autumn, wash, separate the main root, branch root and rhizome, and dry. Rich in notoginseng saponins, notoginseng polysaccharides, notoginseng, and flavonoids, it has the functions of stopping bleeding, promoting blood circulation and removing blood stasis, reducing swelling and relieving pain, nourishing and strengthening, anti-fatigue, hypoxia resistance, anti-aging, lowering blood fat, blood sugar, Improve the immune function of the body and so on. It has extremely high economic value and is widely planted in Yunnan, Guangxi and other regions of my country. However, pathogenic bacteria and soil-borne dis...

Problems solved by technology

[0003] At present, the methods to deal with the obstacle of continuous cropping of Panax notoginseng in the industry are mainly to deal with the soil that has been planted with Panax notoginseng in multiple ways, including chemical pesticide soil disinfection method, high temperature water steam soil disinfection method, flame calcination soil disinfection method, microbial agent addition method, chlorination method, etc. Bitter soil fumigation method, however, the above methods except chloropicrin can achieve large-scale scale, the rest of the methods are in the experimental stage and the method is single and unsystematic. The heavy metals are not up to standard, etc. According to the method, the operation steps are cumbersome and costly. Based on the current income of Panax notoginseng, it is difficult to plant on a large scale on Panax notoginseng

Although the chloropicrin soil fumigation method can realize large-scale cultivation of Panax notoginseng, its high toxicity is extremely harmful to humans and animals, and it is a highly toxic chemical hazard. poisoning hospitalization
