After the greenhouse cucumber is planted, the planting water is planted. When the seedlings are slowed down, the seedling water is poured again. After that, the watering is suspended, the cultivating is strengthened, and the new roots are promoted. When the melon is sitting, the melon is thick and long, and the sun is selected in the morning to promote the fruit growth. In cucumber planting, in addition to the diagnosis based on the young fruit phase, it is also necessary to determine whether to water or not according to the cucumber variety, plant growth status, soil fertility, humidity and weather conditions. The only standard for fruit water. After sitting in the root melon, the cucumber enters the result period with the temperature getting higher, the stems and leaves and the fruit are advancing, the leaf transpiration is increased, the water absorption is increasing, and the irrigation amount is gradually increasing. When watering cucumbers, you should choose sunny watering in the morning, and you can release the wind in time. If it is watered on cloudy days, the humidity in the shed is large, and the relative humidity of the air is more than 90%. It is easy to form a water film on the surface of the leaves, or the condensation time of the leaves is long. It affects the gas exchange of the leaves, and at the same time limits the transpiration of water, thereby affecting the absorption and photosynthesis of water and fertilizer by roots, and is easy to induce diseases such as downy mildew. Cucumber roots are light and fat, and they are not resistant to fertilizer. From the beginning of the root melon, they need to be topdressed 8 to 10 times. In the initial stage of cucumber and melon, topdressing is applied, 7-9 kg of urea per acre, 8-12 kg of potassium sulfate, or 12-15 kg of three-element compound fertilizer. From late February to early March, as the outside temperature rises, the management of fertilizer and water should be strengthened. Generally, water is poured once every 7 days, and the fertilizer is chased after 15 days. After watering, pay attention to ventilation and moisture. During the cucumber melon period, the demand for fertilizer and water increased. Each acre can be combined with watering to apply 15-20 kg of three-element compound fertilizer, or 10 kg of potassium fertilizer and 20 kg of nitrogen fertilizer. After the cucumber fruit season, the amount of topdressing should be gradually reduced, and the last time there is no need to chase potash. At the peak of the melon, the foliar top dressing can be carried out with a mixture of 0.3% urea and 0.3% potassium dihydrogen phosphate.
