What are the latest fertilization precautions for cucumbers?

Cucumber is a kind of gourd vegetable with very high nutritional value and numerous effects and benefits. It is a very popular vegetable in our country, and its planting area in our country is now very large. When growing cucumbers, fertilization work is essential. And when fertilizing, there are many points that require our attention. So what exactly should be noted when fertilizing cucumbers? Let's take a look together below!

1. Nitrogen fertilizer application must not be excessive

Nitrogen fertilizer is an indispensable fertilizer in cucumber growth, and rational application of nitrogen fertilizer is the key to ensuring cucumber yield. However, we must pay attention to controlling the amount of nitrogen fertilizer applied; applying too much will instead produce the opposite effect. During the cucumber seedling stage, if too much nitrogen fertilizer is applied, it easily causes excessive vegetative growth of the seedlings. The leaf area of overgrown seedlings increases, and the leaves are thin and relatively pale in color. This leads to decreased stress resistance and makes them susceptible to cold damage. If too much nitrogen fertilizer is applied during the fruiting stage, it will affect the fruit-setting rate of cucumbers, cause fruit abortion, and easily produce deformed cucumbers, bitter cucumbers, and so on.

2. Pay attention to balanced fertilization

When fertilizing, we must pay attention to controlling the amount of fertilizer applied. If too much fertilizer is applied, it will increase the salt content in the soil and affect the cucumber plants' absorption of water and nutrients. This will not only hinder the growth of cucumber plants, but also easily produce various deformed cucumbers. Therefore, when fertilizing, we must pay attention to controlling the nutrient ratio in the fertilizer. Nitrogen and potassium fertilizers should be the main ones, with phosphorus fertilizer as a supplement. Among them, the proportion of nitrogen fertilizer is the highest, potassium fertilizer is next, and phosphorus fertilizer is last. Therefore, we must attach importance to the application of potassium fertilizer.

3. Pay attention to rational topdressing

Many farmers, when growing cucumbers, think that as long as sufficient base fertilizer is applied, then less fertilizer can be applied in the later stages of cucumber growth. In fact, this is a wrong idea, because as cucumbers are harvested, nutrients are continuously lost with the cucumbers. Therefore, a stable and long-term nutrient supply is needed. If topdressing work is not taken seriously in the later stages of cucumber growth, the plants will show premature senescence due to lack of fertilizer. This leads to a shortened effective harvest period and insufficient yield. Therefore, in order to ensure sufficient nutrition for cucumbers in the later stage, after cucumber planting, topdressing should be done about 5 times, combined with organic fertilizer application.

4. Pay attention to foliar fertilizer application

The application of foliar fertilizer is also very important for cucumber growth. When applying foliar fertilizer, we should follow the principle of applying whatever is lacking. We should timely supplement the nutrients the plants lack. However, there are also many precautions. When applying foliar fertilizer containing large amounts of hormones, we must be cautious, because large amounts of hormones may cause premature senescence of the plants and reduce yield and quality. Also, care should be taken to avoid mixing it with fungicides, so as to avoid affecting fertilizer efficiency. Finally, it should generally be applied during the peak fruiting stage of cucumbers, because in the later stage, cucumber growth is greater and the demand for fertilizer is also greater. Reasonable spraying of foliar fertilizer can timely supplement the nutrition of cucumbers.

The above is a brief introduction to what should be noted when fertilizing cucumbers. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
