Saffron, also known as saffron, is a precious Chinese medicinal material, which has the effects of activating blood and removing blood stasis, cooling blood and detoxifying, relieving depression and calming the nerves. Due to its unique medicinal properties and precious value, saffron is highly sought after in the market. However, in order to grow high-quality saffron, it is necessary to master certain cultivation methods. Below, we will introduce the cultivation method of saffron in detail.
First, the selection of land preparation.
Choose a flat, well-drained, fertile sandy soil for planting. Before planting, carry out deep tillage, apply sufficient base fertilizer, and keep the soil loose. At the same time, it is necessary to ensure that the water source is sufficient and convenient for irrigation.
Second, the selection of seedlings.
Choose healthy, pest-free seeds for seedling. Before planting in the spring, soak the seeds in warm water to promote germination. Then, the seeds are sown on a seedbed and covered with a thin layer of soil to keep the soil moist. When the seedlings have grown 2-3 true leaves, they can be transplanted.
3. Transplanting and planting.
Transplant the seedlings into the prepared planting plot, keeping the plant spacing and depth appropriate. After transplanting, it should be watered thoroughly in time to promote the survival of seedlings.
4. Field management.
1.Watering: Saffron likes moisture, but avoid standing water. During the growing period, keep the soil moist and avoid drought. In the rainy season, attention should be paid to drainage and waterlogging to prevent the occurrence of root rot caused by stagnant water.
2.Fertilization: Reasonable fertilization according to the growth needs of saffron. During the growth period, nitrogen and potassium fertilizers can be topapplied several times to promote strong plant growth. Phosphorus and boron fertilizers should be applied before flowering to promote flower bud differentiation.
3.Weeding: Regular weeding reduces the competition between weeds and saffron for nutrients and water. During the growing period, keep the field free of weeds.
4.Pest control: Common diseases of saffron include root rot, leaf spot, etc. In the early stage of the disease, it is necessary to spray the agent in time for prevention and control. At the same time, it is necessary to pay attention to the prevention and control of aphids, red spiders and other pests.
5. Harvesting and processing.
When the flowers of saffron bloom, they should be harvested in time. Care should be taken to protect the filaments from damage during harvesting. After harvesting, it should be processed and dried in time to prevent mildew and deterioration. Dried saffron should be stored in a cool and ventilated place.
In short, in order to grow high-quality saffron, you need to master scientific breeding methods. From land selection and land preparation to field management to harvesting and processing, every link must be strictly controlled. Only in this way can we grow high-quality saffron and provide people with better resources of Chinese medicinal materials.
