The causes and Control methods of the latest Cucumber Hollow

Cucumber in our impression is round and plump, juicy, smooth taste, but if the planting environment is not suitable, it will appear some physiological diseases. Many farmers are very worried about the hollow problem of cucumber, which seriously affects the quality and yield of cucumber. So how to prevent cucumber hollowness? Let's take a look.

1. Malnutrition

The fertility of the soil is poor, and if it is not fertilized in time, it will lead to insufficient nutrients of the plant, weak growth, poor root growth, few leaves, limited photosynthesis, and less synthetic nutrients, which can not meet the needs of fruit growth, which will lead to hollow symptoms of cucumber.

Prevention and control methods: in order to grow cucumber well, we must pay attention to fertilization, apply sufficient base fertilizer before planting, apply reasonable topdressing during the growing period, ensure good root growth, strengthen the absorption of fertilizer and water, and improve the yield and quality.

2. Lack of certain elements

In addition to malnutrition, in an adequate nutrition environment, but a lack of boron or potassium can also cause hollowness. The main reason is that in order to increase yield, many farmers apply nitrogen fertilizer blindly or do not apply organic fertilizer or farm manure, the partial application of nitrogen fertilizer will affect the absorption of other elements by the root system, and the absence of organic fertilizer will lead to the lack of trace elements in the soil. resulting in hollow.

Prevention and control methods: fertilization must be scientific and reasonable, the base fertilizer should be farm manure or organic fertilizer as far as possible, and the application amount of nitrogen fertilizer must be controlled, especially in the flowering and fruit stage, when the plant needs less nitrogen fertilizer, it is necessary to increase the application of phosphorus and potassium fertilizer or micro-fertilizer.

3. The cause of high temperature

In high temperature weather, especially when the temperature is too high at night, cucumbers are easy to grow, resulting in uneven growth nutrients and hollow phenomenon, which is a common phenomenon in many greenhouse cultivation.

Prevention and control methods: in high temperature, we should pay attention to the way of strengthening ventilation or spraying water mist to reduce the temperature, and control the temperature in the limit of suitable growth of cucumber, neither high nor low.

4. Moisture causes

When futures rise and fall greatly, because the ground temperature is too low or too high, it will lead to root damage, resulting in cucumber planting water shortage, the proportion of nutrients imbalance. One of the reasons is that long-term exposure to the sun leads to a lack of water in the plant, which can also lead to hollow cucumbers.

Prevention and control methods: pay attention to the change of temperature, reasonable watering, maintain a certain humidity of the soil, but also pay attention to drainage in the rainy season.

The above is the introduction of cucumber hollow reasons and control methods, hope to help you, want to know more related knowledge, please pay attention to us.
