Anti-shelves cucumber "mad long" four methods

If the greenhouse cucumbers are not well managed, they often grow up but do not produce melons, which is called "crazy". The prevention method is: The suitable temperature for controlling the growth and development of cucumber is 25-30°C. If the temperature is higher than 30°C, the growth of plants will be accelerated and it will be easy to grow wild. Therefore, greenhouse temperature should be controlled between 25 ~ 30 °C, should not exceed 30 °C; night temperature is maintained at about 18 °C as well, in order to reduce respiration and increase dry matter accumulation. Control Humidity The proper air humidity for cucumber growth and development is about 85%. When the air humidity in the shed exceeds 85%, the air should be immediately ventilated and dehumidified; in the evening when the temperature is 10 to 15°C, the greenhouse should be ventilated for 1 to 2 hours to reduce the humidity at night, prevent “crazy”, control diseases, and promote flowering. melon. After the hormone protects the melon cucumber, the vegetative growth of the plant is inhibited. Therefore, we must try to make the first batch of flowers more fruit, if the first batch of flowers sitting less, easily lead to "crazy." According to the experiment, using 100% liquid of guagoling hormone to spray flowers and spray flowers can make cucumbers sit on melons, keep melons, and promote the rapid expansion of melons. In this way, the morning market can be raised and the early yield can be increased, and it can effectively prevent Plants "crazy." Reasonable fertilization in the case of ensuring the supply of nitrogen in the soil, the appropriate application of phosphorus, potassium, to prevent the single application of large amounts of nitrogen fertilizer.
