Wheat turning green water is generally watered before and after annual stubble, and the specific time is determined according to soil fertility and other conditions. For the wheat fields with sufficient moisture and fertile soil before winter, it is not necessary to turn over the green water, just keep warm and cultivate the soil properly to promote the development of wheat. The irrigation quantity of green water must follow the corresponding principles to ensure the scientific irrigation method. When the water content of the wheat field is suitable after watering, weeds should be removed in time to ensure the water content.

1. When will the green wheat be watered?

1. Generally, the rejuvenation water of wheat should be watered before and after the annual assault, and the specific time should be based on watering before wintering and soil fertility. For the wheat fields with sufficient watering and fertile soil before winter, only proper heat preservation and soil cultivation can promote the development of wheat. However, in the case of drought, poor soil and late sowing of wheat, it is suggested to irrigate rejuvenation water in time, especially in the northern region.

2. The amount of green water must follow the corresponding principles to ensure scientific watering methods. In many areas, due to the large temperature difference between day and night in early spring, it is often cold and hot. At this time, it is generally advisable to water with small water, so as to avoid flooding and prevent freezing damage to wheat when the air temperature and ground temperature are too low. For wheat fields with small population, slow growth and weak growth in spring, 20 kilograms of urea can be applied while watering each mu. When the water content of the wheat field is suitable after watering, weeds should be removed in time to ensure the water content.

Second, matters needing attention in watering wheat with green water

1. For tall trees, the root system is deep, and only watering once in spring is enough to supply the water needed for trees to turn green normally. However, for some low shrubs, perennial flowers, lawns and newly planted trees, the root system has not been completely re-formed, or the root system is too shallow, windy and rainy in spring, and the soil moisture loses quickly, so one watering is not enough to make these plants turn green normally. Therefore, the watering times of turning green water cannot be set at one time for all plants. It is necessary to decide whether to water once or several times according to the actual situation of plants, soil and weather.

2. In North China (except the north), the average daily temperature can reach 3℃ to 6℃, and the soil has been thawed. At this time, it is more appropriate to water the green water, neither too early nor too late. Irrigation is too early, the soil has not thawed, and it is easy to accumulate water and freeze, causing plant freezing damage. Irrigation too late can not supplement soil moisture in time to play a cold-proof role, nor can it supply the water needed for plant greening in time, which is not conducive to normal plant greening.
