Early growth, early spring, early spring, early spring cucumber growth because the weather is hot and cold, the night temperature is not easy to control, prone to weak seedlings and long seedlings. Weak seedlings and prosperous seedlings are two seedlings of opposite growth status. Weak seedlings are mainly caused by weak light and low temperatures, while long seedlings are caused by high humidity and high temperatures, especially due to high night temperatures. In this regard, if you want to nurture strong and strong, you must control the environmental conditions in the shed. In general, the daytime temperature should be controlled at 25 °C ~ 30 °C, more than 30 °C to increase ventilation. The nighttime temperature should be controlled at 14°C~15°C. If the temperature is too high, it can be solved by early exposing the late lid grass cover and not covering the film; if the nighttime temperature is still high, the grass can be put in the room at night. The top vent is properly opened so that the grass can be pressed against the vent to facilitate nighttime dehumidification.
During the middle growth stage, the management of fertilizer and water management of spring waxy cucumbers will have a large demand for fertilizers and water after entering the nectar period. Therefore, the management of fertilizer and water should be promptly strengthened to prevent premature degeneration of defertilizer. Generally after the removal of the first gourd, we must combine watering and timely fertilization once. Pay attention to the amount of fertilizer should not be too large. At the end of the result, the amount of fertilizer and water should be appropriately increased. At that time, the temperature is already high, and the amount of water evaporation is also large. Generally, it is necessary to apply water and fertilizer once every 5 to 7 days.
In the late stages of growth, the prevention of premature aging is first and foremost, it is necessary to avoid later defermentation. According to the ratio of cucumber to nitrogen, phosphorus and potassium absorption of 5:2:6, topdressing once every 7 to 10 days, combined with a certain amount of rooting agent, promote fruit anti-premature aging effect. Second, we must prevent leaf diseases.
