High-yield cultivation techniques for garland chrysanthemum: grow the emperor's vegetable this way for higher yields
Garland chrysanthemum, also known as emperor's vegetable, Artemisia vegetable, pengflower vegetable, and so on, has high edible and medicinal value, and can also be cultivated as an ornamental plant. So, what high-yield cultivation techniques are there for garland chrysanthemum? Let's find out together!
1. Variety selection
Garland chrysanthemum is mainly divided into small-leaf garland chrysanthemum and large-leaf garland chrysanthemum. Among them, small-leaf garland chrysanthemum is more cold-tolerant, has a stronger aroma, and grows faster. Generally, it can be harvested in just one and a half months to 2 months, but its yield is lower. Large-leaf garland chrysanthemum has broad leaves and higher yield, with tender and short stems, and good variety quality, but its disadvantages are slow growth and late maturity. The main type chosen for planting is large-leaf garland chrysanthemum, which has high yield and good market price. However, variety selection should be based on the actual conditions of the planting area. If it is a northern region, small-leaf garland chrysanthemum is generally planted; if it is a southern region, large-leaf garland chrysanthemum is generally planted.
2. Environmental factors
Garland chrysanthemum originated in our country. It has strong adaptability and a certain degree of cold tolerance. It likes cool, humid environments. The suitable growth temperature is 17-20 degrees. It is not tolerant of high temperatures. When the temperature is higher than 29 degrees, growth is poor. Garland chrysanthemum is not strict about light and can grow normally in low-light environments. It is also not strict about soil requirements, and grows best in loose, fertile sandy loam. It is not strict about water requirements either; during growth, it is only necessary to keep the soil moist, but too much water will affect its growth and development. In short, garland chrysanthemum can be planted in all major regions of our country.
3. Cultivation techniques
Garland chrysanthemum can be planted three times a year: sowing in spring from February to April, sowing in autumn from August to September, and sowing in winter from October to November. Before planting, first prepare the land and make beds. Choose a plot with deep soil, loose fertility, and convenient drainage. After applying sufficient base fertilizer, mix the soil and fertilizer evenly, then make beds. Generally, the bed width is about 1.6 m, and it can be changed according to actual conditions. Break the soil into fine particles and rake it level before sowing. Before sowing, first soak the seeds to promote germination. Place the seeds in a greenhouse and soak them for 24 hours, then place them in a greenhouse environment to promote germination. After sprouting, they can be sown. Sowing can use three methods: direct sowing, broadcast sowing, and drill sowing. About one week after sowing, seedlings will emerge. When the seedlings grow 2-3 true leaves, thinning can begin. For thinning, the plant and row spacing is generally 5-6 cm. Be careful not to make it too sparse or too dense. During planting, pay attention to fertilizer and water management, and water and fertilize according to the weather and plant growth conditions.
4. Pest and disease control methods
Due to temperature and moisture, garland chrysanthemum generally develops downy mildew, so it should be controlled immediately by spraying with Previcur or a 1000-fold Previcur solution, otherwise the yield will be greatly reduced. The main insect pest of garland chrysanthemum is aphids. When they occur, spray a 1500-fold imidacloprid solution for control. When garland chrysanthemum grows to 15-20 cm, harvesting can begin. Generally, harvest once every twenty days or so to avoid affecting quality.
The above are the high-yield cultivation techniques for garland chrysanthemum. I hope they can help you!
