What are the latest causes of cucumber vine death?
When we plant cucumbers, we often run into many things that are unfavorable to cucumber growth. The most common of these is vine death: cucumber seedlings die after breaking through the soil for various reasons. This causes cucumber yields to drop sharply, and farmers' planting profits are seriously affected as a result. So what exactly causes cucumber vine death? Today the editor will briefly introduce it to you. Let's take a look below!
1. Too much fertilizer
When planting cucumbers, many friends apply large amounts of fertilizer blindly in order to increase cucumber yields. They also do not control the application of chemical fertilizer, resulting in too much fertilizer in the soil and excessive concentration, which is very unfavorable to the growth of cucumber seedlings. The excessive heat produced burns the seedlings, and in hot weather water evaporates relatively quickly, thus causing cucumber vine death. Therefore, when fertilizing, we should pay attention to controlling the amount of fertilizer applied, not apply too much, reasonably match the ratio of chemical fertilizer to farmyard manure, avoid fertilizer damage burning the seedlings, and reduce vine death.
2. Too much watering
Cucumbers have a relatively high demand for water during growth, especially during the swelling stage. If water is insufficient, it will have a relatively large impact on cucumber yields. Therefore, many friends apply large amounts of water when watering, but this is actually wrong. We should also pay attention to controlling the amount of watering, and not water too much, especially during the seedling stage. If too much water is applied, or if water is not drained in time during rainy days, the seedlings will suffer flooding damage, causing the root system to be soaked and suffocated, thus resulting in Siyang County Xin. Therefore, when watering, we should water reasonably according to the growth stage of the cucumbers to ensure normal cucumber growth.
3. Causes of pesticide damage
Cucumbers have relatively strong production capacity and relatively good economic benefits. However, cucumbers have relatively poor resistance to pests and diseases, so vegetable farmers habitually use pesticides for control. If pesticides are used improperly or too much is used, causing excessive concentration, then it is very easy to cause pesticide damage to cucumbers, thus causing vine death. So when preventing and controlling pests and diseases, we should pay attention to rotating multiple pesticides. At the same time, pay attention to various use restrictions, reasonably prepare pesticides, and avoid excessive pesticide concentration. In summer, do not spray pesticides during the high-temperature period at noon, and protect the cucumber plants well.
4. Causes of disease
As just mentioned, cucumbers have relatively many diseases. Therefore, disease is also one of the main causes of cucumber vine death. Among the common diseases, Fusarium wilt, downy mildew and damping-off all cause cucumber death. Therefore, when planting cucumbers, we should pay attention to doing a good job of disease prevention. Strengthen field management, do a good job of disinfection regularly, control the amount of water and fertilizer, and maintain a suitable environment to promote cucumber growth. After discovering disease, promptly identify exactly what disease it is, and then take corresponding measures for prevention and control to avoid spreading the disease.
