Water and fertilizer management should be done well for overwintering cucumber
The fertilizer and water management of cucumbers in greenhouses in winter is very important. If the fertilizer and water management are not properly managed, it will cause bad phenomena such as rotten roots, retting roots, and yellowing leaves. For this reason, water and fertilizer management should be done well in production to promote increased production. 1. Fertilization. 1. After soil testing, according to the soil nutrient status and the law of fertilizer requirement for cucumber growth, formula fertilization is carried out to meet cucumber growth requirements. Judging from the current soil conditions in the greenhouse, the fertilization law suitable for cucumber growth is organic fertilizer plus compound fertilizer plus micro-fertilizer plus active beneficial bacteria fertilizer, and a combination of organic fertilizer and inorganic fertilizer. 2. The top dressing is mainly multi-element compound fertilizer and organic fertilizer, combined with biological bacterial fertilizer, and a combination of base fertilizer and flushing fertilizer. This can activate the soil layer, thereby increasing the area of ​​root extension and replenishing a large number of nutrients required by the plant. Do not increase the dosage blindly. If the base fertilizer is too much, it will cause burning of seedlings; if the amount of flushing fertilizer is too large, it is easy to cause root rotten and retting. With the aging of the shed, proper application of biological bacterial fertilizer is one of the feasible measures to improve the soil. Biological fertilizer contains a variety of beneficial bacteria, which can activate the soil, increase low temperature, and regulate soil nutrition. Therefore, proper application of biological fertilizer can promote root development and improve cucumber disease resistance. 2. Watering. 1. Watering time: In winter, shed cucumbers should be watered in the morning on a sunny day, because the water temperature is close to the ground temperature at this time, and the ground temperature is easy to rise, and there is sufficient time for dehumidification in the afternoon. Try to avoid watering in the evening and even cloudy days, so as not to increase the air humidity and cause the occurrence and spread of vegetable diseases. 2. Watering amount: When the cucumbers in the shed are seriously short of water in winter, do not water them too much at one time, which may cause the roots to suffocate and rot. Try to water small water as much as possible, and at the same time, pay attention to draining moisture as much as possible. If the humidity is too high, it is easy to cause downy mildew, bacterial spot and other diseases. 3. Water temperature: Watering in winter*** Choose groundwater, and the water temperature should not be lower than 8℃. The ground temperature should be restored as soon as possible on the day of watering. Cucumbers will be planted through the winter, and good fertilizer and water management will be very important to increase production.
