Polygonatum polygonatum polygonatum (Polygonatum polygonatum vulgaris), Polygonatum polygonatum (Polygonatum multiflora), Polygonatum polygonatum (Polygonatum polygonatum polygonatum (Polygonatum poly Its rhizome is horizontal, cylindrical, and the nodules are swollen, which is a traditional Chinese medicinal material, which has the effects of nourishing qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys. In recent years, with people's pursuit of healthy life and the re-understanding of traditional Chinese medicine, the market demand for Polygonatum polygonatum has gradually increased, and the number of wild Polygonatum polygonatum in the mountains has been relatively reduced for many years. So, when is the best time to grow Polygonatum polygonatum?
The planting time of Polygonatum polygonatum varies depending on the region, climate, soil, and other factors. In general, Polygonatum prefers warm and humid climates, and is suitable for growing in deep, loose, fertile, and well-drained soils. Therefore, when choosing the planting time, it is necessary to take into account the local climatic conditions and soil conditions.
In the southern region, due to the warm and humid climate and the four distinct seasons, the planting time of Polygonatum polygonatum is relatively flexible. Generally speaking, spring and autumn are the best times to grow Polygonatum polygonatum in the southern region. In spring, the temperature gradually rises and the soil gradually warms up, which is conducive to the growth and germination of Polygonatum polygonatum. In autumn, the temperature gradually decreases and the air humidity gradually increases, which is conducive to the expansion of rhizomes and nutrient accumulation of Polygonatum polygonatum polygonatum Planting Polygonatum polygonatum in these two seasons can achieve higher yields and quality.
In the northern region, due to the cold and dry climate, the cultivation time of Polygonatum polygonatum is relatively strict. Generally speaking, the best time to grow Polygonatum polygonatum in the northern region is in the spring. At this time, the temperature gradually rises and the soil gradually thaws, which is conducive to the growth and germination of Polygonatum polygonatum. At the same time, when planting Polygonatum polygonatum in the northern region, it is necessary to pay attention to heat preservation and moisturizing to ensure the normal growth of Polygonatum polygonatum polygonatum
In addition to seasonal factors, the following points need to be paid attention to when planting Polygonatum polygonatum:
1. Site selection. Polygonatum prefers to grow in deep, loose, fertile, well-drained soils. Therefore, when choosing a planting site, you need to choose a place with high and dry terrain, good drainage, loose and fertile soil, and avoid planting in low-lying and wet places.
2. Fertilization. Polygonatum prefers plenty of fertilizer, so it needs to be adequately fertilized before planting. Generally speaking, 2000-3000 kg of well-rotted organic fertilizer needs to be applied to each mu, and 50-100 kg of compound fertilizer needs to be added at the same time to ensure the nutrients required for the growth of Polygonatum polygonatum.
3. Watering. Polygonatum prefers a moist environment, so it needs to keep the soil moist during the growing period. In the dry season, it needs to be watered in time to ensure the normal growth of Polygonatum polygonatum. At the same time, it is also necessary to pay attention to drainage when watering to avoid soil water accumulation leading to root rot of Polygonatum polygonatum polygonatum root.
Fourth, pest control. Polygonatum polygonatum is susceptible to pests and diseases during its growth, so regular pest control is required. A combination of biological control and chemical control can be selected to ensure the healthy growth of Polygonatum polygonatum polygonatum
In conclusion, the best time to grow Polygonatum polygonatum varies depending on the region, climate, soil, and other factors. When choosing the planting time, it is necessary to comprehensively consider the local climatic conditions and soil conditions, and choose the appropriate season for planting. At the same time, in the planting process, it is also necessary to pay attention to the problems of site selection, fertilization, watering and pest control to ensure the healthy growth and high yield and high quality of Polygonatum polygonatum polygonatum.
