How to fertilize eggplant? A full analysis of the latest precautions
Eggplant is a vegetable that many people enjoy eating very much. In China, both household planting and large-scale planting areas are very large. When growing eggplant, watering and fertilizing work is very important. If the eggplant does not absorb enough water and nutrients, then the yield and quality of the eggplant will be greatly affected. However, when fertilizing, there are many points we need to pay attention to, so let's take a look below with the editor at the precautions for fertilizing eggplant!
1. Pay attention to the amount of nitrogen fertilizer applied
Although eggplant has a relatively large demand for nitrogen fertilizer during its growth process, when applying nitrogen fertilizer we should pay attention to the principle of applying small amounts many times. Each time urea and other nitrogen fertilizers are applied, the amount must not exceed 30kg. Because after urea enters the soil, it is very easily transformed. After the eggplant plant absorbs sufficient nitrogen, the other excess nitrogen will be fixed by the soil. Especially in sandy soil and other soils with good permeability, the proportion of nitrogen fertilizer loss will be even greater.
Moreover, if too much nitrogen fertilizer is applied, it will have a great impact on the growth of eggplant. Nitrogen fertilizer will produce a large amount of ammonia gas, causing the leaves, fruits and other organs of eggplant plants cultivated in protected areas to suffer gas damage. In addition, if there are too many nutrients, then the eggplant plant is prone to cell division and other situations, leading to excessive vegetative growth, resulting in deformed fruit, small fruit, rotten fruit, etc. So when fertilizing, we should pay attention to controlling the amount of nitrogen fertilizer applied, and must never apply too much.
2. Fertilizer must not be applied by flushing with water
Many people, when fertilizing, are used to combining it with watering work and applying fertilizer by flushing. Although this method is relatively common, it is not suitable for use in summer and other high-temperature seasons. Because in a high-temperature environment, if chemical fertilizer is applied by flushing, then the chemical fertilizer will produce a large amount of ammonia gas, which will not only reduce fertilizer efficiency, but also easily cause eggplant ammonia poisoning. Therefore, when fertilizing, we should adopt fertilization methods such as furrow application and hole application, then water an appropriate amount after application, and after topdressing, cover with soil about 5cm to avoid excessive volatilization of chemical fertilizer.
3. Pay attention to the nutrient ratio of fertilizer
Although eggplant has the greatest demand for nitrogen fertilizer during its growth process, we cannot ignore the application of phosphorus and potassium fertilizer, and when fertilizing we cannot apply only nitrogen fertilizer or apply it one-sidedly. After eggplant enters the full fruit stage, apply about two rounds of three-element compound fertilizer as topdressing. Keep the amount at 40kg/mu. This provides sufficient nutrition for eggplant growth. However, in the later stage of eggplant growth, the amount of phosphorus fertilizer applied as topdressing should also be controlled well. Prevent too much phosphorus fertilizer, which causes excessive development of fruit seeds, resulting in hardening of the seed coat, etc., and reducing the edible value of eggplant.
The above is a brief introduction to the precautions for fertilizing eggplant. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
