When is the best time to water corn?
Corn is an important grain crop in our country. Many farmers rely on it to make money to support their families. If corn is to have high yield, it is necessary to do a good job of watering. When is the best time for watering corn?
1. Watering when sowing
After sowing corn, if the soil moisture content is relatively high when sowing, you can not water it. If the soil is dry, it should be watered. Generally, the soil water content is 65-75% of the field water holding capacity, which can promote the germination of corn seedlings, improve the germination rate and prevent the occurrence of broken ridges.
2. Watering at jointing stage
After the maize seedlings enter the jointing stage, the plants begin to grow rapidly. At this time, the water demand increases. Generally, the soil water content is 60-65% of the field water holding capacity. If the soil water content is relatively low, watering must be done. Watering at jointing stage is particularly important, because it will not only affect the growth of maize plants, but also affect the heading and flower bud differentiation of maize.
3. Watering during heading period
When corn plants enter heading stage, not only the temperature will be very high, but also the leaf area will be the largest. Therefore, corn needs the most water during the whole growth period of corn at heading stage. Generally, soil water is 70-80% of field water holding capacity. Therefore, when soil water content decreases, it is necessary to water in time. Watering at heading stage could not only increase photosynthetic products of leaves, but also increase pollination rate of maize, laying a foundation for early filling of maize at later stage.
4. Watering during filling period
After corn enters filling stage, it still needs more water. Generally, soil water is 70-75% of field water holding capacity. Sufficient water can make corn grain filling better, thus improving yield. Therefore, water corn early if the soil is short of water after it enters the filling stage.
