The latest watering time of wheat and matters needing attention

It is well known that watering is needed in the process of wheat planting. Wheat watering generally has four periods, but not all of these four periods have to be watered. Sometimes too much watering will affect the growth of wheat. Let's learn about the watering time and precautions of wheat with the editor.

1. Head covered water

Generally, it is carried out 7-10 days after sowing. In some areas, the planting of wheat is relatively dry, resulting in uneven emergence of wheat or weak seedlings. Watering water at this time is conducive to the growth of wheat, whether it is for the emergence rate or seedling Qi, seedling is strong, have a period of effect.

2. Overwintering water

The purpose of overwintering water is to prevent the freezing injury of wheat in winter. In some areas, the temperature will drop sharply in November, and in such a sudden drop in climate, especially when the temperature is below zero, wheat is extremely prone to frost injury, which will lead to yellow seedlings in light and directly freeze to death in heavy seedlings. At this time, it is necessary to irrigate the frozen water in advance according to the weather forecast, which can reduce the temperature difference between the soil and the outside world, so that the wheat will not stop growing because of the sudden drop in temperature.

3. Return to green water

The return to green water is usually carried out in the middle of spring March, when the temperature begins to pick up and the wheat enters the stage of rapid growth. After a winter growth, sufficient water is needed to maintain the normal growth in the later stage.

4. Grouting water

If there is not enough water in the filling period of wheat, it will affect its normal filling, resulting in less full grains and more blighted grains, seriously affecting the yield and quality, so watering during the filling period is very important.

5. Points for attention

It is not suitable to water when the field is not dry, the above watering period is based on drought, if the local precipitation is sufficient, it is not necessary to water, so as to avoid waste cost, in addition, wet field will also increase the harm of diseases and insect pests. Overwintering water is watered during the day, the temperature is above zero, so that it will not freeze, but when the temperature is below zero at night, it may freeze and melt during the day, so it is better to pour winter water. The return to green water is usually irrigated in the middle of March, but if the field is not too dry, it can be postponed, and so is the filling period. It is not suitable to be watered when it is not particularly dry, and improper watering may cause lodging, so watering should be careful during the filling period.
