What are the precautions for planting Gentiana scabra? A full breakdown of the key points
Gentiana scabra is a herbaceous plant whose rhizome is used as medicine, and it has extremely high medicinal value. It has strong adaptability and can be planted in most areas of our country. What issues need attention when artificially cultivating Gentiana scabra? Come and take a look at the detailed introduction with the editor.
1. Selection of soil
Gentiana scabra likes a moist and cool environment, so when choosing a site, you must choose an environment with sufficient water sources to facilitate its growth. In addition, the terrain of the planting site should be relatively flat, preferably with sufficient sunlight, and at the same time pay attention to the soil fertility conditions. Choose soil rich in organic matter, and avoid clayey soil when selecting soil. In addition, before planting, the soil needs to be deeply plowed, and base fertilizer should be applied in combination with plowing.
2. Loosening soil and weeding
During the growth of Gentiana scabra, the presence of weeds will affect its growth to a certain extent, so weeding must be carried out regularly to prevent weeds from running rampant. When weeding, do it appropriately; when the soil lacks organic matter and moisture, it will become compacted, and this situation will cause difficulty in root respiration, which is unfavorable to its growth and, in severe cases, can cause the roots to suffocate and die. Therefore, the soil should be loosened appropriately, but when loosening the soil, be careful not to damage the root system of Gentiana scabra. When loosening the soil, it should not be too deep. When loosening the soil, transplanting and planting can be carried out, and after transplanting, at least 2 more soil loosenings are still needed.
3. Fertilizer and water management
When planting Gentiana scabra, water must be supplemented appropriately to avoid the effects of dryness on its growth. When the soil is severely dry, Gentiana scabra will wilt due to lack of water, and in severe cases the plant will die. Topdressing is also necessary. If you want the crop to grow, fertilization is indispensable. When topdressing, first carry out foliar spraying, spray twice, and combine it with the application of phosphate fertilizer and farmyard manure. When Gentiana scabra is budding, except for the plants kept for seed, the rest should have their flower buds removed. This can not only improve yield and quality and thereby reduce nutrient consumption, but also concentrate nutrients to supply rhizome growth.
4. Pest and disease control
The prevention and control of pests and diseases is necessary. Under normal circumstances, Gentiana scabra is very prone to leaf spot disease. This disease mainly harms the leaves of Gentiana scabra, causing a certain degree of damage to it, and can even cause death. Therefore, in order to prevent this disease, the soil must be disinfected before planting, and the seedlings must also be disinfected. Control the planting density. For diseased plantings, they can be destroyed to eliminate the pathogen, and the diseased holes should be disinfected to prevent the pathogen from infecting other plantings through the soil. When the condition is severe, chemical drugs should be sprayed for treatment to avoid large-scale spread.
