How to fertilize cucumbers? A detailed explanation of the key points of scientific fertilization techniques
Cucumber is one of the common vegetables in our daily lives. It is rich in a variety of vitamins and also has the effect of clearing heat and detoxifying, and its weight-loss and beauty benefits are deeply loved by women. When growing cucumbers, reasonable fertilization is the key to obtaining a high yield, so how should cucumbers be fertilized? Let's learn about it together with the editor.
1. Apply sufficient base fertilizer
Cucumbers have an extremely high yield, so they have a large demand for fertility, which makes applying sufficient base fertilizer the key to growing cucumbers. Calculating on the basis of a yield of 5000 kg per mu, they need to absorb 11.14 kg of pure nitrogen, 7.66 kg of pure phosphorus, and 15.57 kg of pure potassium. The base fertilizer is mainly organic fertilizer, paired with an appropriate amount of chemical fertilizer. The fertilization method is to apply it all at once together with land preparation. Generally, 4000-5000 kg of decomposed organic fertilizer is applied per mu, paired with 30 kg each of urea and diammonium phosphate, as well as 20 kg of potassium chloride. If planting in spring and autumn, the fertilization amount can be correspondingly reduced by about 10%-20%.
2. Fertilizing seedlings
The seedling stage is a key period for cultivating strong seedlings and is also the foundation for ensuring a high-yielding plant, so during the seedling stage, timely topdressing is needed to promote robust seedling growth. Because the base fertilizer is sufficient during the seedling stage, there is no need to apply heavy fertilizer. Generally, to promote seedling growth, a method combining organic fertilizer and chemical fertilizer is used. Apply 100—150 kg of decomposed organic fertilizer or decomposed chicken manure per mu, paired with an appropriate amount of urea and superphosphate, but to avoid fertilizer burn to the seedlings, in most cases the fertilizer is dissolved in water and poured on, which can both speed up the fertilizer absorption rate and improve the fertilizer utilization rate.
3. Timely topdressing
After planting, the plant enters its peak growth period. At this time, the plant's vegetative growth and fruit development proceed together, creating an extremely large demand for fertility. Cucumber is a shallow-rooted crop with a relatively weak preference for fertility, so at this time it must be fertilized several times to ensure that plant growth and fruit development have enough nutrients. According to research, if the cucumber yield per mu reaches more than 5000 kg, from planting until the end of harvesting, topdressing is needed 80-10 times, and each fertilization can apply 10—15 kg of diammonium phosphate per mu, or 250—300 kg of human feces and urine diluted with water and poured on.
4. Fertilizing outside the roots
Fertilizing outside the roots generally refers to foliar spraying, mainly to prevent deficiency symptoms caused by the plant lacking a certain trace element, and it can also prevent premature aging of the plant. Foliar spraying is generally used during the peak fruiting period, when the temperature is relatively low, root activity is relatively weak, and absorption capacity is relatively poor, so to satisfy normal fruiting, the needed nutrients can be supplemented.
