1, land cultivation
The main nutrients for planting Chinese herbal medicines come from soil, so the selection and cultivation of planting sites are the basic conditions for successful planting. We should not only consider the ecological environment it needs, but also consider the national standards of Chinese herbal medicines. Choose convenient soil that is flat, fertile, sunny and meets the national planting standards in all aspects. Secondly, we should apply more basic fertilizers, mainly compost, manure and organic fertilizer. Take the land preparation as the boundary, and make the flat boundary and high boundary according to different terrain.
2. Cultivation techniques
Schizonepeta tenuifolia is usually sown in March and April in spring and 9 1 in autumn. The most commonly used propagation method is seed propagation. We need to choose mature, full, dark brown or brown seeds that are free from pests and diseases, and sow them by sowing or drilling. Generally, the row spacing should be kept at about 20cm, sowing evenly, and then covering the seeds with soil. Pay attention to the feet, water properly and keep the soil moist, which can promote seedling emergence.
3. Field management
It usually takes about ten days and a half months to sprout. Our field management of Schizonepeta tenuifolia is generally divided into three stages, namely, seedling management, growth management and late growth management. At the seedling stage of Schizonepeta tenuifolia, that is, about four or five centimeters, a intertillage weeding should be carried out. When the seedlings grow to about eight to ten centimeters, it is necessary to start thinning. The distance between each plant is about15cm, and at the same time, it is necessary to water and fertilize reasonably. Fertilization is mainly based on nitrogen fertilizer. During the growing period, intertillage weeding should be carried out every twenty days or so. When Schizonepeta tenuifolia grows to about 25 cm, a little potassium fertilizer is needed. When it is 30 cm high, it is mainly mixed with cake fertilizer, which is used in conjunction with phosphate fertilizer and potash fertilizer. In the late growth stage, we only need to let them grow naturally and keep the growth of Schizonepeta tenuifolia, so as to improve the quality and yield of Schizonepeta tenuifolia.
4, pest control
The main diseases of Schizonepeta tenuifolia are root rot, stem blight and black spot. We need to strengthen field management, timely drainage, and increase plant resistance through fertilization. Secondly, we can use Dixon, Bordeaux mixture, carbendazim and so on. For control. The most common pests are ground tigers, mole rats, moths and so on. Bacillus thuringiensis emulsion can be used in the early stage of pests, and pyrethroid pesticides should be used for spraying and killing when pests are serious.
Schizonepeta tenuifolia has strong adaptability to the environment, and has low requirements for planting environment. However, when planting Schizonepeta tenuifolia, it is still necessary to master its planting methods, so as to plant Schizonepeta tenuifolia with high yield and high quality. Then let's share the school search here today. Please pay attention to the next issue for more details of Schizonepeta tenuifolia.
