What are the latest technical methods and tutorials for controlling excessive vegetative growth in cucumbers?

Cucumber is a very popular gourd vegetable in our daily lives, and it has a very large market demand in China. When growing cucumbers, management work is very important. If management is improper, cucumbers are highly prone to excessive vegetative growth and leggy growth, leading to reduced yield and lower quality. So when growing cucumbers, what techniques are there for controlling excessive vegetative growth? Below, the editor will briefly introduce them to everyone. Let's take a look together!

1. Reasonable watering

Watering is very important for the growth of cucumbers. When watering, attention should be paid to controlling both ends and promoting growth in the middle. Before cucumbers enter the fruiting stage, watering should follow the principle of cultivating and preserving soil moisture and raising soil temperature. Keep the soil in a state of alternating dry and wet. After entering the fruiting stage, water about once a week. Before picking cucumbers each time, be sure to water once to prevent excessive rampant growth. Then after the top cucumbers are harvested, also control the amount of watering well to promote the emergence of new roots.

2. Scientific fertilization

While ensuring sufficient nitrogen in the soil, appropriately increase the proportion of phosphorus and potassium fertilizers, and apply topdressing fertilizer in the form of liquid fertilizer. Usually, before the root cucumber has swollen, apply an appropriate amount of urea as topdressing, generally about 18 kg per mu. Combine it with an appropriate amount of potassium sulfate, diammonium phosphate, etc. Then in the later period, apply topdressing once every two harvests. In the middle and late periods, apply about two rounds of decomposed farmyard manure along with water. Do not apply excessive nitrogen fertilizer, otherwise cucumbers are highly prone to excessive vegetative growth.

3. Temperature control

During the growing period of cucumbers, temperature control requires special attention. The suitable temperature for cucumber development is generally around 28 degrees. It must not exceed 30 degrees at most. If it exceeds 30 degrees, cucumber plants are also highly prone to rampant growth. Therefore, during cucumber growth, the daytime temperature should be maintained at around 25-30 degrees, and the day-night temperature difference should be controlled at around 10 degrees. Prevent excessively strong respiration in cucumbers from affecting the accumulation of dry matter in the plants.

4. Humidity control

Humidity is also very important for the growth of cucumbers. We should adjust air humidity according to the growth habits of cucumbers. During the growth and development period of cucumbers, humidity should be maintained at around 70%. The humidity in the greenhouse must not exceed 85% at most. If it exceeds this, ventilation should be done in time to reduce the humidity in the greenhouse. When the daily sunset temperature is around 12 degrees, ventilate for about one hour. This can reduce the temperature and humidity in the greenhouse at night, prevent them from being too high and causing excessive vegetative growth in cucumbers, and can also effectively prevent pests and diseases and improve the flowering and fruiting rate of cucumbers.

The above is a brief introduction to what cucumber excessive vegetative growth control techniques there are. In addition to the above, we should also do various tasks well, such as vine tying and fruit protection, to ensure healthy growth of cucumbers. That is all for today's introduction.
