How do you prevent premature aging in cucumbers? The latest control methods are here

When we grow cucumbers, although the yield of cucumbers is relatively high, we often encounter some problems that affect the growth of cucumbers, especially in the middle and late stages. Premature aging often occurs, and premature aging of cucumbers seriously affects the yield of cucumbers, and the quality is also reduced as a result. This in turn affects the planting benefits of growers. So when we grow cucumbers, how should we prevent premature aging in cucumbers? Let's take a look below!

1. Nourish and protect the roots

One of the reasons for premature aging in cucumbers is root aging. Therefore, to prevent premature aging in cucumbers, we must do a good job of nourishing and protecting the roots. The maximum low temperature inside the greenhouse must not exceed 25 degrees, to promote root growth. Pay attention to the timing when watering. It is best to water before 10 o'clock, and do not water in the afternoon, to avoid high soil temperature and low water temperature making it impossible for the roots to adapt, which instead causes damage. If the soil becomes compacted, remove the plastic film in time and carry out shallow intertillage hoeing to improve soil permeability and promote normal cucumber growth.

2. Fertilizer and water management

In the late stage of cucumber growth, we should do a good job of water and fertilizer management according to the growth of the plants. When topdressing, combine it with watering once, and apply a high-nitrogen-potassium compound fertilizer by flushing, but be careful to control the amount to prevent excessive fertilizer from causing root burn in the cucumber plants. Usually topdress once every 2-3 weeks to provide sufficient nutrients for the growth of the plants and fruits. For cucumber roots that have already begun to age in the late growth stage, appropriately apply a foliar fertilizer once, such as potassium dihydrogen phosphate, humic acid foliar fertilizer, etc., about once a week, to supplement the nutrients the plants lack due to insufficient root capacity and slow down the aging process of the plants.

3. Prevent high-temperature heat damage

After the temperature in the cucumber greenhouse exceeds 30 degrees, do a good job of ventilating and cooling. Especially in the afternoon, when the temperature is higher, increase the ventilation openings. Then, according to weather changes, soil moisture content, and other actual conditions, do a good job of watering to cool down, mainly with frequent light irrigation, to avoid heat damage that blocks the growth of cucumber stems and leaves, leading to premature aging. If ventilation, irrigation, and other cooling methods are not very ideal, then promptly cover with a shade net, which can effectively lower the temperature. But note that the shade net can only be covered under high temperature and strong light. When natural light weakens or when natural light is insufficient on cloudy and rainy days, be sure to pull the shade net open in time.

4. Strengthen management

During the cucumber growth period, control the height of the plants well. If the cucumber stems and vines approach the top of the greenhouse, lower the vines in time. When lowering the vines, also pay attention to the height. If it is too low, it is very unfavorable to the growth of cucumbers. After lowering the vines, the plant height should be kept at about 1.5 m, and the plants should retain at least 20 functional leaves. The leaves should remain evenly distributed on the plants to improve photosynthetic efficiency. Then promptly remove diseased and insect-damaged leaves and fruits, such as withered leaves, yellow leaves, diseased and pest-damaged fruits, deformed fruits, etc. This avoids consuming too many nutrients, concentrates the nutrients in healthy fruits, and can also improve permeability and promote plant growth.

The above is a brief introduction to how to prevent premature aging in cucumbers. In addition to the above, we must also do a good job in the prevention and control of diseases and pests to ensure healthy cucumber growth. That is all for today's introduction.
