What causes cucumber seedling death
When we grow cucumbers, we often run into many things that are bad for cucumber growth. The most common of these is seedling death: cucumber seedlings die after breaking through the soil for various reasons. This causes cucumber yields to drop sharply, and farmers' growing profits are severely affected as a result. So what is going on with cucumber seedling death? Today the editor will give you a brief introduction, so let's take a look below!
1. Too much fertilizer
Many friends, when growing cucumbers, apply large amounts of fertilizer blindly in order to increase cucumber yields. And they do not control the amount of chemical fertilizer applied, so the soil ends up with too much fertilizer and excessive concentration, which is very bad for the growth of cucumber seedlings. The heat produced is too great and burns the seedlings, and in hot weather water evaporates fairly quickly, thus causing cucumber seedling death. Therefore, when fertilizing we should pay attention to controlling the amount of fertilizer, not apply too much, and reasonably match the ratio of chemical fertilizer to farmyard manure, to avoid fertilizer burn of seedlings and reduce seedling death.
2. Too much watering
Cucumbers need a lot of water during growth, especially during the swelling stage; if there is not enough water, then cucumber yields will be greatly affected. So many friends apply a lot of water when watering, but this is actually wrong too. We should also pay attention to controlling the amount of watering, not watering too much, especially during the seedling stage. If too much water is applied, or if there is a lot of rain and drainage is not done in time, then the seedlings will suffer from waterlogging, causing the roots to be soaked and damaged, 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. Pesticide damage
Cucumbers have fairly strong production capacity and good economic returns. However, cucumbers have fairly poor resistance to pests and diseases, so vegetable growers habitually use pesticides for control. But if pesticides are used improperly or too much is used, causing the concentration to be too high, then it is very easy to cause pesticide damage to cucumbers, thus causing seedling death. So when preventing and controlling pests and diseases, we should pay attention to rotating the use of multiple pesticides. At the same time, pay attention to the various usage restrictions, mix pesticides reasonably, and avoid pesticide concentrations that are too high. In summer, do not spray during the high-temperature period at noon, and protect the cucumber plants well.
4. Disease
As just mentioned, cucumbers have quite a lot of diseases. So disease is also a main cause of cucumber seedling death; among the common diseases are fusarium wilt, downy mildew and damping-off, all of which can cause cucumber death. Therefore, when growing cucumbers, we should pay attention to doing a good job of disease prevention. Strengthen field management, do regular disinfection work, control the amount of water and fertilizer well, and maintain a suitable environment to promote cucumber growth. After discovering disease, promptly find out exactly what disease it is, then take corresponding measures for prevention and control, to avoid the condition spreading.
