Understanding the Latest Fertilizer Requirements of Cucumbers in One Article

Cucumber cultivation is very common in our country, and nowadays there are a great many people growing cucumbers in our country. Although the method of growing cucumbers is simple, the management work during cultivation is also very important. And when growing cucumbers, fertilizing is an indispensable task; when we fertilize, we must fully understand the fertilizer requirements of cucumbers. So below, the editor will introduce the fertilizer requirements of cucumbers to everyone. Let's take a look!

1. Fertilizer Requirement Rules

Generally, when cucumbers are grown in open fields, from sowing to harvest takes about 3-5 months. But if they are cultivated overwinter in a greenhouse, then the growth period of cucumbers can be as long as about 9 months. The length of the cucumber growth period and its fertilizer requirement rules are affected by many environmental factors. According to professional data surveys, every 1000kg of cucumbers requires about 2kg of pure nitrogen, about 1kg of phosphorus pentoxide, and about 4kg of potassium oxide. The ratio is generally about 1:0.5:1.5. Throughout the entire growth period of cucumbers, the demand for potassium fertilizer is the greatest, followed by nitrogen and phosphorus.

2. One Month After Planting

One month after cucumbers are planted, the demand for nitrogen fertilizer rises sharply. Then after two months it begins to decline. One month after planting, the order of cucumber organs in terms of nitrogen demand from high to low is leaves, fruit, stems. After 50 days, the absorption amounts of leaves and fruit are similar. After 2-3 months, the absorption amount of the fruit gradually exceeds that of the leaves. Throughout the entire growth period of cucumbers, phosphorus is also an indispensable substance, especially one month after planting, when the effect of phosphorus fertilizer is most obvious. And potassium is also indispensable; whether for vegetative or reproductive growth, a shortage of potassium will cause cucumber yields to decline.

3. Harvest Period

During the harvest period of cucumbers, the fertilizing work must also be done well. At this time, the requirement for potassium is the greatest, followed by nitrogen. Then an appropriate amount of calcium, magnesium, phosphorus and other substances must also be supplemented. Just at the start of harvesting, the fertilizer uptake of cucumbers will decrease somewhat, while during the harvest period the uptake will increase noticeably. Finally, in the later stage, it will gradually decrease again. Because after cucumbers are harvested, most of the nutrients in the plant are lost along with the fruit, so the higher the yield, the greater the demand for nutrients. Therefore, the topdressing work during the fruiting period of cucumbers is very important, and everyone must pay close attention to it.

The above is a brief introduction to the fertilizer requirements of cucumbers. When growing cucumbers and fertilizing, we must be sure to do the fertilizing work well according to the fertilizer requirement rules of cucumbers, so as to provide sufficient growth nutrients for cucumbers, increase yields, and ensure planting returns. That is all for today's introduction. This article is for reference only, and we hope it can be of some help to everyone.
