Planting method for improving yield and effective component content of medicinal plants

Abstract

The invention discloses a planting method for increasing the yield and the effective component content of medicinal plants, and belongs to the technical field of medicinal plant planting, the planting method for increasing the yield and the effective component content of the medicinal plants includes the steps of soil preparation, shed building, sowing, cultivation and harvesting; in the soil preparation step, biochar and soil are uniformly mixed and hatched; in the step of shed building, a medicinal plant planting greenhouse is built, and the concentration of carbon dioxide in the greenhouse is set to be 700-1000 ppm; according to the planting method for increasing the yield and the content of the effective components of the medicinal plants, the charcoal and the carbon dioxide are used in a combined mode, the synergistic effect of the charcoal and the carbon dioxide can be effectively achieved, and the purpose of increasing the yield and the content of the effective components is economically, environmentally friendly and efficiently achieved.

Description

technical field [0001] The invention belongs to the technical field of medicinal plant planting, and in particular relates to a planting method for improving the yield and active ingredient content of medicinal plants. Background technique [0002] Chinese herbal medicine is mainly composed of the roots, stems, leaves and fruits of medicinal plants, and has the advantages of high specificity and safety in medical treatment. In my country, the use of medicinal plants in medicine has a history of more than 2,000 years and is an important part of Chinese medicine. Among medicinal plants, Radix Radix is ​​taken as an example to illustrate: Radix Radix is ​​a common perennial herbal medicinal plant belonging to the family Caryophyllaceae. The main effects include replenishing Qi and strengthening the spleen, promoting body fluid and moisturizing the lung. It is mostly used to treat spleen deficiency and fatigue, loss of appetite, weakness after illness, lack of Qi and Yin, spont...

However, the impact of such environmentally friendly soil additives on the yield and quality of Pseudostellaria remains unknown

[0005] But the prior art still has the following defects: (1) using chemical fertilizers in large quantities is not conducive to the sustainable development of the ecological environment: there are studies to show that Pseudostellaria heterophylla is more sensitive to fertilizers, and too much fertilization will cause the leaves to be too green, the resistance is poor, and there is a possibility of reducing production. trend (Wu Yuxiang et al., 2017); secondly, when the amount of fertilizer applied exceeds the capacity of vegetation absorption and soil nutrient retention, the fertilizer dissolved in the soil water environment will flow into the surrounding water source, causing environmental problems such as eutrophication of the water body; in addition, the single fertilizer Adding a large amount of potassium chloride can easily lead to acidification or alkalinization of the soil, etc., and the microbial balance will also be destroyed, which is not conducive to the development of sustainable medicinal plant cultivation. growth; phosphate fertilizers contain heavy metal elements (cadmium, arsenic, lead, etc.), and long-term application increases the risk of soil pollution; long-term application of nitrogen fertilizers not only makes the soil carbon-nitrogen ratio imbalance, soil microbial balance imbalance, but also nitrate in nitrogen fertilizers can also interact with The reaction of amine compounds in the soil produces strong carcinogens (nitrosamines), which cause soil pollution and affect plant quality; (2) the use of plant growth regulators will cause potential safety problems: First, although the application site of growth regulators is The aboveground parts of plants will inevitably enter the soil. Because many plant growth regulators have stable physical and chemical properties and slow degradation, they will cause a certain degree of soil pollution; secondly, in the cultivation of medicinal plants in China, the abuse of regulators is a problem. It is extremely prominent, so many literatures do not advocate the blind use of plant growth regulators (Gu Xiaohong et al., 2017); (3) The use of environmentally friendly additives for active ingredients of medicinal plants is relatively limited: compared with chemical fertilizers and plant growth regulators, Considering that waste recycling environment-friendly soil additives have more advantages and application prospects, however, the current research on the active ingredients of such soil additives on medicinal plants is relatively scarce and limited; in addition, considering the formation of Pseudostellaria polysaccharides Taking photosynthesis products as raw materials, only using soil additives has a relatively limited promotion effect on photosynthesis efficiency and carbohydrate formation
