What to pay attention to when applying fertilizer to cucumber

Cucumber belongs to a kind of melon vegetable, which has very high nutritional value and many functions. It is a very popular vegetable in our country, and now the planting area in our country is also very large. Fertilization is essential when planting cucumbers. When applying fertilizer, there are many things that need our attention. So what should we pay attention to in cucumber fertilization? Let's take a look at it with the editor.

1. Nitrogen fertilizer should not be applied too much.

Nitrogen fertilizer is an indispensable fertilizer in cucumber growth, and reasonable application of nitrogen fertilizer is the key to ensure cucumber yield. However, we must pay attention to control the amount of nitrogen fertilizer, if used too much, it will be counterproductive. In the cucumber seedling stage, if too much nitrogen fertilizer is applied, it is easy to cause the seedlings to grow excessively. The leaf area of overgrown seedlings increased, and the leaves were thin and light in color. It leads to the decline of stress resistance and is vulnerable to frost injury. If too much nitrogen fertilizer is applied in the melon-bearing period, it will affect the melon-setting rate of cucumber, appear the phenomenon of melon, and easily produce deformed melon, bitter melon and so on.

2. Pay attention to balanced fertilization

When applying fertilizer, we must pay attention to controlling the amount of fertilizer applied. If too much fertilizer is applied, it will increase the salt in the soil and affect the water and nutrient absorption of cucumber plants. It will not only hinder the growth of cucumber plants, but also easily produce all kinds of malformed melons. Therefore, when we apply fertilizer, we must pay attention to control the proportion of nutrients in the fertilizer. Give priority to nitrogen and potassium fertilizer, supplemented by phosphate fertilizer. Among them, the proportion of nitrogen fertilizer is the highest, followed by potash fertilizer, and finally phosphate fertilizer. Therefore, we must pay attention to the application of potash fertilizer.

3. Pay attention to reasonable topdressing

When planting cucumbers, many farmers feel that as long as they apply sufficient base fertilizer, they can apply less fertilizer in the later stage of cucumber growth. In fact, this is a wrong idea, because with the harvest of cucumbers, nutrients will continue to be lost with cucumbers. Therefore, it is necessary to have a stable and long-term nutrient supply, if the cucumber does not pay attention to topdressing in the late growth stage, then the plant will appear premature senescence due to the lack of fertilizer. As a result, the effective harvest time is shortened and the yield is insufficient. Therefore, in order to ensure adequate nutrition in the later stage of cucumber, after cucumber planting, topdressing should be applied for about 5 times and combined with organic fertilizer.

4. Pay attention to the application of foliar fertilizer

The application of foliar fertilizer is also very important for the growth of cucumber. When we apply foliar fertilizer, we should follow the principle of what is lacking. The lack of nutrition of the plant should be replenished in time. However, there are also many precautions, we must be cautious when applying foliar fertilizer containing a large amount of hormones, because a large amount of hormones may cause premature senescence and reduce yield and quality. And pay attention to avoid mixing with fungicides to avoid affecting fertilizer efficiency. Finally, it is generally applied in the peak period of cucumber, because in the later stage, the growth of cucumber is larger, and there is a great demand for fertilizer. Reasonable spraying of foliar fertilizer can supplement the nutrition of cucumber in time.

The above is a brief introduction of what cucumber fertilizers should pay attention to. That's all for today's introduction. This article is for reference only. I hope it can help you all.
