Timing of Wheat Irrigation Matters: Keep the Latest Precautions in Mind

Everyone knows that wheat needs watering during the growing process. Wheat irrigation generally has 4 periods, but these four periods do not all require watering, and sometimes watering too much can affect wheat growth. Let's learn about wheat watering timing and precautions together with the editor below.

1. Head-covering water

It is generally done 7-10 days after sowing. In some areas, wheat planting is relatively dry, resulting in uneven emergence or weak seedlings. Watering once at this time is beneficial to wheat growth, and has a certain effect on both the emergence rate and uniform, strong seedlings.

2. Overwintering water

The main purpose of overwintering water is to prevent freezing damage to wheat in winter. In some areas, the temperature drops sharply in November, and under such a sudden drop in climate, especially when the temperature is below zero, wheat is very prone to freezing damage, causing yellow seedlings in mild cases and directly freezing the seedlings to death in severe cases. At this time, it is necessary to irrigate the freezing water in advance according to the weather forecast, which can reduce the temperature difference between the soil and the outside, so that wheat will not stop growing due to a sudden drop in temperature.

3. Green-up water

Green-up water is generally applied in early to mid-March in spring, which is also the green-up period of wheat. At this time, the temperature begins to rise, and wheat enters a stage of rapid growth. After a winter of growth, sufficient water is needed to maintain normal growth in the later stage.

4. Grain-filling water

If wheat lacks sufficient water during the grain-filling period, it will affect its normal grain filling, leading to plump grains being insufficient and more shriveled grains, seriously affecting yield and quality. Therefore, watering during the grain-filling period is extremely important.

5. Precautions

When the field is not dry, it is not suitable to water. The above watering periods are all based on drought. If local rainfall is sufficient, there is no need to water, so as to avoid wasting costs. In addition, wet fields will also increase the harm of pests and diseases. Water overwintering water during the day, when the temperature is above zero, so that freezing will not occur. At night, when the temperature is below zero, watering may freeze, and then melt during the day. Watering overwintering water under such conditions is better. Green-up water is generally applied in mid-March, but if the field is not too dry, it can be postponed. The same is true for the grain-filling period. When it is not particularly dry, it is not suitable to water. Improper watering may cause lodging, so watering during the grain-filling period must be done carefully.
