Seedless watermelon under the application of membrane drip irrigation technology, the effect of increasing production is very obvious, if there is no membrane drip irrigation technology will affect its yield and quality. The application of seedless watermelon drip irrigation technology not only improves the utilization rate of fertilizer and water, reduces the humidity of leaf surface, reduces the occurrence of pests and diseases, but also saves a lot of water resources and reduces the amount of chemical fertilizers. The control of the leaf surface humidity is also one of the important measures for the cultivation of the watermelon. The determination of the leaf surface humidity can be performed using a leaf surface humidity sensor.
Humidity in the field should be reduced as much as possible throughout the growing season to control the occurrence of blight, anthrax, blight, blight and leaf blight. The drip follows the principle of “wet without squeaking, dryness, and droughtâ€. According to the scientific management of the water requirement of the seedless watermelon during each growth period, the relative humidity of the soil is maintained at 50% to 60%. 80% of roots of seedless watermelon distributed 2030 from the surface. In the soil layer, the topsoil is very easy to dry, so the drip pipe should be a small number of times. With water topdressing, many times topdressing urea and nitrogen, phosphorus, and potassium compound fertilizers after growing and growing cucumbers to increase the yield and commodity rate of seedless watermelons.
The humidity sensor on the leaf surface of the watermelon measures and controls the humidity of the leaf surface of the watermelon. It is found that the covering film further improves the drip irrigation water saving effect, achieves a stable temperature and moisturizing effect, avoids excessive air humidity, reduces anthrax, blight, blight, leaf blight, and the like. happened.
