Description

Use of Mao Cumu mould in relieving continuous cropping obstacle of Ginseng radix or Saviae Miltiorrhizae radix The invention relates to a divisional application of trichoderma in relieving continuous cropping obstacle of ginseng or red sage root, with application number 202510650239.1 and application date 2025, 5 and 20. Technical Field The invention relates to the technical field of crop cultivation, in particular to application of trichoderma viride in relieving continuous cropping obstacle of ginseng or red sage root. Background Continuous cropping obstacle refers to abnormal growth and development of crops caused by continuous cultivation of homologous crops or related crops on the same soil. Symptoms are generally growth dysplasia, yield and quality reduction, in extreme cases, partial death of seedlings, no or no vigorous seedling emergence, brown stain, branch reduction, low activity and narrow distribution range of most damaged plant roots, and reduced capability of absorbing water and nutrients. At present, with the increase of planting areas of ginseng and red sage root and the pursuit of genuine medicinal materials, the problem of continuous cropping obstacle is gradually highlighted. Continuous cropping can impair plant growth, lead to deterioration of physical and chemical properties of soil, unbalance of microbial communities, exacerbation of soil-borne diseases, and finally lead to reduction of crop yield and quality. In addition, in order to reduce disease incidence and increase ginseng and red sage yields, some farmers increase the use of fertilizers and pesticides, which leads to degradation of soil environment and excessive pesticide residues. Therefore, the continuous cropping problem becomes a serious problem to be solved in ginseng and red sage cultivation, and the sustainable development of the cultivation is severely restricted. In view of this, the present invention has been made. Disclosure of Invention The invention aims to provide an application of trichoderma in relieving continuous cropping obstacle of ginseng or red sage root, and aims to relieve chemical property deterioration and soil microorganism change of soil in continuous cropping obstacle of ginseng or red sage root, increase content of active ingredients of ginseng and red sage root and improve quality of continuous cropping ginseng or red sage root. In order to achieve the above object of the present invention, the following technical solutions are specifically adopted: According to one aspect of the invention, the invention provides an application of trichoderma in relieving continuous cropping obstacle of ginseng or red sage root. The trichoderma provided by the invention is applied to relieving continuous cropping obstacle of ginseng or red sage root. The invention is obtained through intensive research and creative labor, and trichoderma can effectively relieve the chemical property deterioration and the microbial change of soil after continuous cropping of ginseng or red sage root, further improve the chemical property of soil after continuous cropping of ginseng or red sage root, increase the relative abundance of beneficial bacteria in soil, inhibit the relative abundance of harmful bacteria, and increase the content of active ingredients of ginseng and red sage root, and improve the quality of continuous cropping of ginseng or red sage root. In a preferred embodiment of the invention, the continuous cropping obstacle of ginseng or red sage root means that the chemical property of soil is deteriorated and the microorganism of the soil is changed after ginseng or red sage root is continuously planted for 4-6 years. The deterioration of the chemical properties of the soil comprises the reduction of the content of available nutrients in the soil and the reduction of the content of organic matters in the soil. The soil microbial change comprises that the relative abundance of beneficial microorganism bacillus is reduced, and the relative abundance of harmful microorganism pathogen fusarium is increased. In a preferred embodiment of the invention, the trichoderma is applied in the form of an irrigation liquid; Preferably, the concentration of trichoderma in the irrigation liquid is 1 x 10 7cfu·mL-1~9×107cfu·mL-1, preferably 1 x 10 7cfu·mL-1. In a preferred embodiment of the present invention, the application method comprises transplanting seedlings of ginseng or red sage root into a continuous cropping obstacle land of ginseng or red sage root, and then irrigation planting by using the irrigation solution. The irrigation planting method comprises the steps of applying the water to the whole growth period of transplanted ginseng or red sage seedlings for 2 times, applying 500ml/m 2 each time, and keeping the water management consistent with the field management in the rest time. Note that the method of applying 2 times in the whole growth period is to apply the first irrigation at the time of transplanting and apply
