Causes and Control methods of Cucumber Hollow

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

1. Malnutrition

The fertility of the soil is poor, and it is not timely topdressing, it will cause insufficient nutrients in the plant, weak growth, poor root growth, less leaves, limited photosynthesis, less synthetic nutrients, which cannot meet the needs of fruit growth, which will lead to hollow symptoms of cucumber.

Control methods: in cucumber planting to want it to grow well, we must pay attention to fertilization, before planting to apply enough base fertilizer, in the growth period to be reasonable topdressing, to ensure good root growth, for fertilizer and water absorption capacity to strengthen, conducive to yield and quality improvement.

Lack of certain elements

In addition to malnutrition, hollowing can occur in nutrient-rich environments, but if boron or potassium is lacking. The main reason is that many farmers in order to improve yield, blind fertilization, partial application of nitrogen fertilizer or no application of organic fertilizer and farm manure, partial application of nitrogen fertilizer will affect the absorption of other elements by roots, no application of organic fertilizer will lead to the lack of trace elements in soil, resulting in hollow.

Control methods: Fertilization must be scientific and reasonable, base fertilizer as far as possible to farm manure or organic fertilizer, must control the amount of nitrogen fertilizer, especially in the flowering and fruiting period, the plant for nitrogen demand is less, then to increase the application of phosphorus and potassium fertilizer or micro-fertilizer.

3, high temperature reasons

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

Prevention and control methods: pay attention to the high temperature, can improve the ventilation or spray water mist way to cool down, the temperature control in the cucumber suitable growth limit, not high nor low.

4. Water causes

When the futures rise and fall sharply, due to the low or high ground temperature, it will lead to root damage, which will cause cucumber planting water shortage, nutrient imbalance. Good, one reason is that prolonged exposure to sunlight causes plants to lack water, which also causes cucumbers to be hollow.

Control methods: pay attention to temperature changes, reasonable watering, maintain a certain humidity of the soil, but also pay attention to drainage in the rainy season.

The above is the cucumber hollow reasons and prevention methods introduced, I hope to help you, want to know more about the relevant knowledge, please pay attention to us.
