What are the latest fertilization methods for garland chrysanthemum?
Garland chrysanthemum is a very popular wild vegetable in our country, but with people's extensive picking, the wild quantity has also declined sharply. Now it is basically all artificially cultivated varieties, and artificial cultivation requires us to do a lot of management work, among which fertilization is a very important point. So what is the fertilizer requirement pattern of garland chrysanthemum? How should garland chrysanthemum be fertilized? What are the precautions? Let's take a look together with the editor below!
1. Fertilizer requirement pattern
The growth of garland chrysanthemum requires a large amount of nutrients, among which the demand ratio for nitrogen, phosphorus and potassium is the highest. The main edible part of garland chrysanthemum is the tender stem, and during the planting process the demand for nitrogen is relatively large, so when fertilizing we should mainly use nitrogen fertilizer, combined with an appropriate amount of phosphorus and potassium fertilizer. The seedling stage of garland chrysanthemum does not have a large demand for nutrients, but when it grows to about 9 true leaves, the fertilizer demand will gradually increase. Therefore we must adjust water and fertilizer management according to the growth condition of garland chrysanthemum, to ensure that garland chrysanthemum growth has sufficient nutrients. When the plant grows to about 19 cm, it can be harvested.
2. Apply sufficient base fertilizer
As just said, the growth period of garland chrysanthemum is relatively short, the root ability is relatively strong, but the distribution is not deep, and it has relatively strong fertilizer tolerance. Therefore before planting, sufficient base fertilizer should be applied, and the amount of base fertilizer should be controlled according to the planting area. The base fertilizer is mainly fully decomposed farmyard manure, and then an appropriate amount of compound fertilizer is added. Spread it evenly on the soil surface, and then carry out the land preparation work. If planting in an arched shed is used, then in the autumn of the previous year the base fertilizer should be applied, to ensure that the soil can fully absorb the fertilizer nutrients and improve soil fertility.
3. Timely topdressing
The growth cycle of garland chrysanthemum is about 40 days, so our topdressing work is very important. Although the growth cycle is short, about three topdressings should be applied during the entire growth period of garland chrysanthemum. The first time is when the garland chrysanthemum seedlings grow to about 9 cm, and the fertilizer is mainly ammonium sulfate, etc., to improve the growth vigor of the seedlings and enhance resistance. Then when the seedlings grow 3-5 true leaves, topdress again, with quick-acting nitrogen fertilizer as the main fertilizer. Finally, when the seedlings grow to about 11 cm, topdress together with watering, with compound fertilizer as the main fertilizer. Because garland chrysanthemum can be harvested multiple times, we must topdress once after each harvest, and the topdressing frequency should be maintained at about 1 week, to avoid reducing the quality of garland chrysanthemum.
4. Precautions
Garland chrysanthemum belongs to a kind of leafy vegetable. Due to the short growth period, many vegetable farmers will neglect the reasonable application of fertilizer when fertilizing. When fertilizing, we cannot apply only one kind of fertilizer, especially nitrogen fertilizer. If nitrogen fertilizer is excessive, it will not only reduce the quality of garland chrysanthemum, but also increase the nitrate content of garland chrysanthemum, harming human health. Therefore when fertilizing we must pay attention to a reasonable ratio of nutrients, pay attention to the application of phosphorus and potassium fertilizer, ensure the normal growth of garland chrysanthemum, and avoid the phenomenon of nutritional deficiency.
The above is a brief introduction to the fertilization methods of garland chrysanthemum. The growth ability of garland chrysanthemum is very strong, so during growth its demand for nutrients is very large. Therefore when planting we must meet the nutrient needs of garland chrysanthemum, strengthen fertilization work, ensure the growth of garland chrysanthemum, and when fertilizing we should also pay attention to watering, to prevent garland chrysanthemum from drying out and dying due to lack of water.
