In dryland seed melons, due to the influence of rainfall, the output is extremely unstable. Therefore, where irrigation is required, artificial irrigation should be carried out as far as possible.
The melons in the middle and lower reaches of the Yangtze River have entered the dry season at the later stage of their development. They often need to be replenished with water and have more rows of furrow irrigation.
The melon farmers all over the country have accumulated rich experience in irrigation, which is generally not watering at the seedling stage, extending the vine without pouring or pouring as appropriate. The fruit is rapidly inflated and watered frequently. The amount of water should be large, and it should be stopped 5-7 days before harvesting. Watering. In addition to water and water, it is more important to look at the growth of the plants. The leaf color of the melon is light green and the top of the melon vine grows upwards, indicating that the water in the plants is too high to be watered; leaf color Dark green, thick vine leaves, indicating that the plant body water is appropriate; leaf noodles slightly curled at noon, the leaves can not return to normal, indicating that the plants are seriously deficient in water, must be timely irrigation.
Watering melons should be dominated by ditching, and flood irrigation should not be used. The ditch is watered with water, and the depth of water infiltration is 1-2 times deeper than that of barrage. Watering should be done in the morning and evening.
Once it enters the rainy season, it has more precipitation, more soil moisture and less soil porosity. When the permeability is poor, the root respiration of melons is often hindered and the absorption capacity is weakened, which seriously affects fertility. Continuous accumulation of water for more than 12 hours, the melon root is prone to lignification, such as the cortex completely rot for 5 days. Therefore, care must be taken to remove the drain and not to accumulate water near the melon root.
