Compared with greenhouses and exposed cucumbers, greenhouse cucumbers have a prolonged growth period. Therefore, instead of adopting the traditional bamboo “stands†cultivation, the management of stems and vines is based on rope “hanging vinesâ€. In this way, the height of cucumber plants can be reduced by “falling vines†to improve ventilation and light transmission, promote the growth of cucumber stalks, and continuously produce melons to increase yields. At the same time, it is also convenient for later management. When you come to cucumbers, you must master the following tips:
1. Grasp the fall time. It is best to grow on the top of the cucumber close to the roof, the bottom without leaves, vines scattered above the ground when more than 30 cm.
2. Control watering before falling. Do not water the cucumber one week before falling, control the soil moisture, its purpose is to reduce the plant stem water content, enhance stem vines toughness, to prevent falling vines due to high water content of the stem and crisp and easy to fold.
3. Remove the old leaves of the base. All the old leaves and diseased leaves at the base of the stalks shall be taken off before falling, and shall be taken out of the greenhouse for destruction to prevent contact between the base leaves of the vines and soil pathogens, and the incidence of infection will endanger the entire greenhouse cucumber. After removing the old leaves of the base, the whole functional leaves should be maintained at more than 20 pieces.
4. Be light when falling. In order to prevent injury, it is best to choose sunny afternoon fall. The specific operation of the action should be light, the base stem vines along the direction of natural bending coiled around the fall, avoid pulling hard to pull hard to prevent the vine stem injury or even broken. Melon vines fall on the mulch, so that it is easy to manage when walking between the rows, and second, it can prevent the cucumber stalks from rooting in the soil and make the grafting roots lose meaning. Each time about 80 centimeters of vines are covered, the distance between the base blade and the ridge surface after the falling vine is required to be more than 15 cm.
5. Strengthen management after falling. After falling, it is necessary to properly raise the temperature in the greenhouse, promote the healing of cucumber stem wounds as soon as possible; Second, according to the occurrence of cucumber disease sprayed pesticides, strengthen disease prevention and control to prevent bacteria from entering; third, timely watering and fertilization, auxiliary Spray fertilizer on leaves to increase the supply of fertilizers and water, prompting the plants to restore their vitality, long leaves, flowering and fruiting as soon as possible, and increase their yield. Fourth, the side shoots that germinate from the base of stems should be removed to concentrate the nutrients for the growth of the main stem.
