How to Grow Crown Daisy for High Yield? Detailed Explanation of Key Cultivation Techniques
Crown daisy, also called chrysanthemum greens, looks a bit like a chrysanthemum. In ancient times it was a dish served at the imperial court, so it is also called emperor's vegetable. It is a crop that combines food, ornamental and medicinal uses, and has the effect of nourishing the spleen and stomach and relieving phlegm. Below, QinNong Net brings you the high-yield cultivation techniques for crown daisy. Let's take a look.
1. Variety Selection
Crown daisy is mainly divided into small-leaf crown daisy and large-leaf crown daisy. Among them, small-leaf crown daisy is more cold-tolerant, has a stronger aroma and grows faster; it generally only takes one and a half months to 2 months to harvest, but its yield is lower. Large-leaf crown daisy has broad leaves and a higher yield, with tender and short stems and good variety quality, but its drawbacks are slow growth and late maturity. The main type chosen for planting is large-leaf crown daisy, which has a high yield and a good market price.
2. Environmental Factors
Crown daisy originated in our country. It has strong adaptability and a certain degree of cold tolerance, prefers a cool, humid environment, and its suitable growth temperature is 17-20 degrees. It is not tolerant of high temperatures; when the temperature is above 29 degrees, growth is poor. It is not strict about light, and can grow normally even in a low-light environment; it is also not strict about soil, and grows best in loose, fertile sandy loam; it is not strict about water either, and during growth it only needs the soil to remain moist, but too much water will affect its growth and development. In short, crown daisy can be planted in all major regions of our country.
3. Cultivation Techniques
Crown daisy can be planted three times a year: sowing in spring from February to April, in autumn from August to September, and in winter from October to November. Before planting, first prepare the land and make beds. Choose a plot with deep soil, loose and fertile soil, and convenient drainage. After applying enough base fertilizer, mix the soil and fertilizer evenly. Then make beds, generally about 1.6 m wide, which can be changed according to actual conditions. Break the soil up finely 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 put them in a greenhouse environment to promote germination. Once they sprout, they can be sown. Sowing can use three methods: direct sowing, broadcasting, and drilling. About one week after sowing, seedlings emerge. When the seedlings grow 2-3 true leaves, they can be thinned. Thinning is generally done at a plant and row spacing of 5-6 cm, and care must be taken 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 the growth condition of the plants.
4. Pest and Disease Control Methods
The main diseases of crown daisy are anthracnose and downy mildew. When they occur, spray with a 1000-fold dilution of Previcur for control; the main pest is aphids, and when they occur, spray with a 1500-fold dilution of imidacloprid for control.
