What are the latest methods for controlling excessive growth of cucumber seedlings?
Cucumber is a very common gourd vegetable in our country, and its planting area in our country is also very large. When planting cucumbers, management work is very important, especially during the seedling stage. If management is improper, cucumber seedlings are very prone to excessive growth, leading to reduced yield. So how should cucumbers be controlled during the seedling stage? Below, the editor has brought you the methods for controlling excessive growth of cucumbers during the seedling stage. Let's take a look together!
1. Growth regulators
During the cucumber seedling stage, in order to avoid excessive growth of the seedlings, we can appropriately use growth regulators, which can effectively prevent cucumbers from growing wildly. However, they must not be used excessively. If growth regulators are used excessively, then cucumber growth will slow down, or even stop growing. Moreover, when the cucumber vines grow to half the trellis, growth regulators must not continue to be used. If they continue to be used, then it will have a great impact on cucumber flower bud differentiation and fruit setting, and planting benefits will also decline as a result.

After stopping the use of growth regulators, we should prevent excessive growth of cucumbers during the seedling stage by controlling the day-night temperature difference. First, we should widen the day-night temperature difference. When the seedlings show excessive growth, the temperature inside the greenhouse should be adjusted in time. Under normal circumstances, during the day, the temperature in the greenhouse should be controlled at around 26-28 degrees, and the day-night temperature difference should be maintained at around 15 degrees. At night, the lowest temperature must not be lower than 10 degrees, otherwise cucumbers are prone to cold damage, affecting normal flowering and fruit setting. A suitable day-night temperature difference can not only prevent excessive growth of cucumbers, but also increase cucumber yield.
3. Water and fertilizer management
Water and fertilizer are also very important for cucumber growth. Cucumbers have strong growth ability and relatively high yield, so when planting, the demand for water and fertilizer is also relatively large. However, the amount used must also be controlled well, especially nitrogen fertilizer. If too much nitrogen fertilizer is applied, then cucumbers are very prone to excessive growth. Therefore, when applying base fertilizer before planting, an appropriate amount of nitrogen fertilizer should be added to the base fertilizer, and then nitrogen fertilizer should no longer be applied during the growth process. Attention should also be paid to controlling the amount of watering. Watering should not be excessive; keeping the soil moist is sufficient. When watering is excessive, drainage should be carried out in time to prevent excessive growth of seedlings.
4. Bending the vines
When planting cucumbers, we should often observe the growth of cucumber seedlings. Especially during seedling growth, no matter when the cucumber plants show spindly growth, we can appropriately bend down the heads of overgrown cucumber vines. Turn the growing point of the vine head downward to avoid excessive apical dominance. This promotes the transport of nutrients within the cucumber plant to the lower and middle parts of the plant, inhibits top growth, can effectively alleviate excessive growth, and thereby achieves the purpose of controlling excessive growth and increasing yield.
The above is a brief introduction to the methods for controlling excessive growth of cucumbers during the seedling stage. Controlling excessive growth of cucumbers is very important and is directly related to cucumber yield and quality, so everyone must pay close attention. That is all for today's introduction.
