How to Fertilize Crown Daisy? Detailed Guide to the Correct Fertilization Method
Crown daisy, also known as emperor vegetable, garland chrysanthemum, and so on, has high edible and medicinal value, and can also be grown as an ornamental plant. So, what fertilization methods are there for crown daisy? Let's learn about them together!
1. Fertilizer requirements
The growth of crown daisy requires a large amount of nutrients, among which nitrogen, phosphorus, and potassium are needed in the highest proportions. The main edible part of crown daisy is the tender stem, and it has a relatively high demand for nitrogen during the growing process. Therefore, when fertilizing, we should mainly use nitrogen fertilizer, combined with an appropriate amount of phosphorus and potassium fertilizer. During the seedling stage, crown daisy does not need much nutrition, but when it grows to about 9 true leaves, the fertilizer demand gradually increases. Therefore, we should adjust water and fertilizer management according to the growth conditions of crown daisy to ensure sufficient nutrition for its growth. When the plant grows to about 19 cm, it can be harvested.
2. Apply sufficient base fertilizer
The growth period of crown daisy is relatively short, and its root capacity is strong, but the roots are not distributed deeply. It has strong fertilizer tolerance, so sufficient base fertilizer should be applied before planting. Control the amount of base fertilizer according to the planting area. The base fertilizer should mainly be fully decomposed farmyard manure, then add an appropriate amount of compound fertilizer, sprinkle it evenly on the soil surface, and then carry out land preparation. If using an arched shed for planting, then basal fertilizer should be applied in the autumn of the previous year to ensure that the soil can fully absorb the fertilizer nutrients and improve soil fertility.
3. Timely topdressing
The growth cycle of crown daisy is about 40 days, so topdressing work is very important. Although the growth cycle is short, topdressing should be done about three times throughout the entire growth period of crown daisy. The first time is when the crown daisy seedlings grow to about 9 cm, mainly using ammonium sulfate and other fertilizers to improve seedling growth and enhance resistance. Then, when the seedlings grow 3-5 true leaves, topdress again, mainly with quick-acting nitrogen fertilizer. Finally, when the seedlings grow to about 11 cm, carry out topdressing together with watering, mainly using compound fertilizer. Because crown daisy can be harvested multiple times, we should topdress once after each harvest. The topdressing frequency should be maintained at about 1 week to avoid reducing the quality of crown daisy.
4. Precautions
Crown daisy is a kind of leafy vegetable. Because of its short growth period, many vegetable growers neglect the rational application of fertilizer when fertilizing. When fertilizing, we should not apply only one kind of fertilizer, especially nitrogen fertilizer. If nitrogen fertilizer is excessive, it will not only reduce the quality of crown daisy, but also increase its nitrate content, harming human health. Therefore, when fertilizing, we must pay attention to a reasonable nutrient ratio, pay attention to the application of phosphorus and potassium fertilizer, ensure the normal growth of crown daisy, and avoid the phenomenon of nutritional deficiency.
The above are the fertilization methods for crown daisy. I hope they can help you!
