The weather is getting hotter and hotter, and many crops need water management at this time. For melon and fruit crops, water sometimes determines the sweetness level, so what are the water requirements of the watermelon planting stage? Watering must seize several critical water demand critical periods to ensure healthy growth of watermelon. The amount of water required in the seedling stage is relatively small, and measures for water control and squatting are generally adopted to promote root entrenchment and robustness. During the spreading period, the principle of promoting the combination of control should be mastered to keep the soil dry and wet. The watermelon is more sensitive to water after entering the flowering and melon stage. If the water supply is insufficient, the female ovary is small and stunted; if too much water is supplied, it is easy to cause the stems to grow vigorously, which is not good for sitting melons. Moisture is appropriate. 1. Water well for planting Before planting seedlings, dig a pool or put a few large buckets in the shed, put water in advance, raise the water temperature to a temperature close to the temperature of the shed, and then add the expanded EM bacteria or Bacillus subtilis to the water. Fill the planting hole with water added with fungicide. Water about 300 ml per hole. Put the seedlings into the seedlings before the water seeps completely. Then cover the soil with the height of the soil equal to Miaotuo. Avoid deep soil. 2. Lightly pouring slow seedling water When to slow the seedling water is not calculated in days, but depends on the physiological indications of the seedlings: when new leaves begin to germinate (new leaves yellow), and dew appears on the edge of the seedlings, it means that the seedlings have slowed down. It is necessary to start to slow the seedling water (even if the soil is not particularly dry), the amount of water should be determined according to the soil properties of the shed, the health of the seedlings, and the local temperature conditions. It must be flexible. In general, the amount of water for slow seedlings should not be too large. 3. Skillfully pouring melon water Different varieties have different times for pouring melon water. It cannot be generalized, but depends on the type of melon. Generally speaking, small watermelons should be watered when the eggs are large, medium-sized watermelons are watered when the ducks are large, and large watermelons are watered when the eggs are large. Watering can not be too early or too late, according to the above principles, watering melon expansion speed is slow. It is not easy to crack melon when watering when the expansion speed is slow, and it is easy to cause cracking when watering when the expansion speed is fast (watering too late). 4. Pour melon water according to local conditions Generally water the watermelon when it grows to the top of the bowl. If the watering of the melon is timely and the amount of water is sufficient, you can not water it. You should judge whether the water shortage is based on the growth of the watermelon plant. Observe the leaves or growth points (faucet) when the sunlight is strongest and the temperature is the highest at noon which performed. If the faucet grows upward, it means that the soil water content is too large and no watering is needed; if the faucet keeps growing parallel to the ground, it means that the water supply can meet the normal growth and no watering is needed; if the faucet bends downward and has a slight wilting The phenomenon indicates that the soil is already short of water and can not meet the normal growth of seedlings, so it must be watered. The above is the main point of watering the watermelon. Everyone should never pour big water when it should not be watered, but do not leave it alone when it should be watered.
