What are the techniques of cucumber growth control?

Cucumber is a very popular melon vegetable in our life, and it has a great market demand in our country. When planting cucumbers, management is very important. If it is not managed properly, cucumbers are easy to grow and grow, resulting in a decline in yield and quality. So what are the techniques for controlling the growth of cucumbers? The following editor will give you a brief introduction, let's have a look!

1. Rational watering

Watering is very important for the growth of cucumbers. When rewatering, we should pay attention to controlling the two ends and promoting the growth in the middle. Before the cucumber enters the melon-bearing period, watering should be based on the principle of ploughing to preserve soil moisture and increase soil temperature. The soil remains dry and wet, and is watered about once a week after entering the melon-bearing period. Before picking melons, we should pay attention to watering once to prevent the phenomenon of crazy growth, and then after the top melon harvest, we should also control the amount of water to promote the emergence of new roots.

2. Scientific fertilization

While ensuring sufficient nitrogen in the soil, the proportion of phosphorus and potassium fertilizer should be increased appropriately, and topdressing fertilizer should be carried out in the form of liquid fertilizer. Usually in the cucumber root melon before the expansion of the appropriate amount of urea, generally topdressing 18kg per mu or so. With appropriate amount of potassium sulfate, diammonium phosphate and so on. Then the mature farm manure should be applied twice with the water in the middle and later stage. Do not apply nitrogen fertilizer, otherwise it is very easy to cause cucumber to flourish.

3. Temperature control

During the growing period of cucumber, temperature control needs to be paid attention to, and the temperature suitable for cucumber development is generally about 28 degrees. The highest can not exceed 30 degrees, more than 30 degrees, cucumber plants are also very easy to grow crazy. Therefore, during the growth of cucumber, the daytime temperature should be kept at about 25-30 degrees, and the temperature difference between day and night should be controlled at about 10 degrees. To prevent excessive respiration of cucumber, affecting the dry matter accumulation of the plant.

4. Humidity control

Humidity is also very important to the growth of cucumbers. We should adjust the air humidity according to the growth habits of cucumbers. During the growth and development of cucumber, the humidity should be kept at about 70%. The maximum humidity in the shed should not exceed 85%. If it exceeds, ventilation should be done in time to reduce the humidity in the shed. Ventilate for about an hour when the sunset temperature is about 12 degrees every day. It can reduce the temperature and humidity in the greenhouse at night, prevent cucumber from blooming and growing too high, effectively prevent the occurrence of diseases and insect pests, and improve the flowering and fruiting rate of cucumber.

The above is the brief introduction of cucumber blooming control technology. In addition to the above, we also need to do a good job in binding vines, protecting melons and other work to ensure the healthy growth of cucumbers. That's all for today's introduction.
