Method for domestication and biocontrol cultivation of wild asarum sieboldii

Abstract

The invention discloses a method for domestication and biocontrol cultivation of wild asarum sieboldii, and belongs to the technical field of traditional Chinese medicine cultivation. The technical scheme is that: from a high mountain area of altitude of 1.8 km, transplanting wild asarum sieboldii downhill for altitude of 0.1 km every year, transplanting continuously for 5 years, introducing the wild asarum sieboldii to a gentle slope area under a mountain in altitude of 1.3 km, in a domestication process, through adding a mixed biocontrol bacterium agent, improving biological environment of planting soil of the asarum sieboldii, combining with field management and pest control, obtaining an asarum sieboldii domesticated cultivated species which adapts to growing environment of altitude 1.3 km. The domesticated cultivated species has characteristics of high medicinal value of a wild species, and adapts to habitat of relatively low altitude of 1.3 km on the south slope of Qinling Mountains. The domesticated cultivated species can be popularized and planted in large-scale. The method can reduce morbidity of the wild asarum sieboldii, and effectively improve yield of the asarum sieboldii while ensuring the medicinal value.

Description

Technical field [0001] The invention belongs to the technical field of traditional Chinese medicine cultivation, and specifically relates to a domestication and biocontrol cultivation method of wild Asarum. Background technique [0002] Asarum is a perennial herbaceous plant of the Aristolochiaceae family. It has a shallow root system and is a negative plant. The medicinal value of wild Asarum is obviously better than that of cultivated species. However, due to the sharp decline of wild resources, high management costs, difficulty in large-scale production, and insufficient total yield, wild Asarum cannot be used as the medicinal asarum. Main source. However, the existing cultivated species partially lost the excellent characteristics of the wild Asarum, and its medicinal value, disease resistance and stress resistance were lower than that of the wild species. And in the wild state, due to the presence of a variety of soil-borne pathogenic microorganisms (especially the pathoge...

Problems solved by technology

The mountainous soil in this area is rich in humus, but at the same time as nourishing the plants, due to the complex composition of the microbial community, pathogenic bacteria are easy to multiply and infect the plants of Huaxixin, causing diseases such as leaf blight, rust, blight, and sclerotinia, which in turn lead to Decline of Yield and Quality of Huaxixin

Excessive use of pesticides will have a serious negative impact on the soil structure and beneficial bacteria in the planting area.

[0004] Although the seed preservation, planting site treatment, planting key points, and pest control techniques involved in the planting process are relatively mature, however, many details need to be corrected when it comes to the unique habitat of the wild species Asarum sinensis and the foothills of the southern slope of the Qinling Mountains.

Taking the treatment of planting land as an example, pure soil preparation and chemical means cannot continuously improve the soil, and the latter may even cause damage to the structure of the soil itself
