What are the matters needing attention in cucumber fertilization?

Cucumber is a popular vegetable, it tastes sweet, tastes very crisp, and the price is not expensive. As a vegetable, it is relatively simple to grow cucumbers, but if you want to achieve high yield, you must master the key step of fertilization. What are the matters needing attention in cucumber fertilization? Let's take a look at it together.

1. The amount of nitrogen fertilizer should not be too large.

The main fertilizer for the growth of cucumber is nitrogen fertilizer, which can increase the yield of cucumber if we can grasp the use of nitrogen fertilizer and control the amount of nitrogen fertilizer. The more nitrogen fertilizer is applied to cucumber, the better. If it is in the seedling stage, using too much nitrogen fertilizer will make the cucumber seedlings grow excessively, resulting in larger leaves, lighter leaves and smaller stems. And the whole cucumber seedling is easy to be infected with diseases and is not resistant to freezing injury. If too much nitrogen fertilizer is used in the fruiting period of cucumber, the whole cucumber will grow too much, the fruit setting rate will decrease, abnormal pulp will appear, and the cucumber will taste bitter.

2. Imbalance in fertilization of cucumber.

In the process of cucumber growth, if the amount of fertilizer is relatively large, it will lead to higher salinity in the soil, so that cucumber absorption of water and fertilizer will be hindered, cucumber growth will be greatly affected, and the phenomenon of abnormal results will occur. Therefore, when topdressing, we must pay attention to the proportion of fertilization, especially the proportion of phosphorus and potassium fertilizer should be determined according to the growing period.

3. Topdressing should be in place.

When planting cucumbers, the base fertilizer must be given enough, but with the growth of cucumbers, the base fertilizer can no longer meet its needs, so it must be properly topdressing. In order to achieve long-term and stable growth of cucumber and absorb nutrients, late topdressing can reduce premature senescence due to lack of fertilizer, reduce harvest time, increase cucumber yield, and reduce the probability of deformed cucumber. According to the relevant experience, if the growth nutrient demand of cucumber can meet its growth, it must be fertilized seven or eight times. In addition, organic fertilizer also needs to be used together.

4. matters needing attention in the use of cucumber foliar fertilizer.

Cucumber growth in addition to base fertilizer and topdressing, proper spraying a little foliar fertilizer is helpful to its growth, generally according to the performance of cucumber lack of fertilizer to see what kind of foliar fertilizer to supplement, mainly pay attention to the following aspects.

First, spraying cucumber foliar fertilizer must not contain a lot of hormones, otherwise it will lead to the weakening of cucumber seedlings in the early stage, the decrease of cucumber yield in the later stage, the decrease of marketability and so on.

Second, cucumbers should not be mixed with fungicides when spraying foliar fertilizer.

Third, cucumber foliar fertilizer is used in the full fruit period of cucumber, when cucumber needs more fertilizer, but the root absorptive capacity of cucumber at this stage is relatively weak, so spraying foliar fertilizer can supplement the nutrients needed by cucumber plants.
