The latest Fertilizer requirement of Cucumber
Cucumber planting is very common in our country, and now there are many people growing cucumbers in our country. Although the planting method of cucumber is simple, the management of planting is also very important. When planting cucumbers, fertilization is an indispensable work. When we apply fertilizer, we should fully understand the fertilizer law of cucumbers. Then the following editor will introduce the fertilizer law of cucumbers, let's have a look!
1. Law of fertilizer requirement
Generally, when cucumbers are planted in the open field, it takes about 3-5 months from sowing to harvest. If it is cultivated in the greenhouse over the winter, the growth period of cucumber can be as long as 9 months. The growth period and fertilizer requirement of cucumber will be affected by many environmental factors. According to the professional data survey, each 1000kg of cucumber needs about pure nitrogen 2kg, phosphorus pentoxide about 1 kg, potassium oxide about 4kg. The proportion is generally about 1.5 per cent. In the whole growth period of cucumber, the demand for potash fertilizer is the largest, followed by nitrogen and phosphorus.
2. One month after planting
The demand for nitrogen fertilizer of cucumber will increase sharply one month after planting. Then it began to decrease after two months, and after one month of planting, the order of the demand for nitrogen in cucumber organs was leaf and fruit stem. After 50 days, the absorption of leaves and fruits was similar. After 2-3 months, the absorption of the fruit will gradually exceed. In the whole growth period of cucumber, phosphorus is also an indispensable substance, especially after one month of planting, the effect of phosphate fertilizer is the most obvious. And potassium is also indispensable, whether nutritional or reproductive growth, lack of potassium will lead to a decline in cucumber yield.
3. Harvest time
Cucumber in the harvest period, it is also necessary to do a good job of fertilization. At this time, the demand for potassium is the greatest, followed by nitrogen. Then it is necessary to supplement an appropriate amount of calcium, magnesium, phosphorus and other substances, at the beginning of harvest, the fertilizer absorption of cucumber will be reduced, while during the harvest period, the absorption will be significantly increased. Finally, when it comes to the later stage, it will gradually decrease. Because most of the nutrients in the cucumber plant will be lost with the melon after harvest, the higher the yield, the greater the demand for nutrition. Therefore, the topdressing work in the cucumber fruit period is very important, we must pay more attention to it.
The above is a brief introduction to the law of cucumber fertilizer requirement. When we plant cucumber fertilizer, we must pay attention to do a good job of fertilization according to the law of cucumber fertilizer demand, so as to improve adequate growth nutrition, increase yield and ensure planting efficiency of cucumber. That's all for today's introduction. This article is for reference only. I hope it can be helpful to all of you.
