When is the best time to water wheat for the second time? Is it more conducive to high wheat yield? In fact, this issue has been discussed with you before, but judging from the situation this year, due to the lack of water in some areas, the first increase in yield has not yet been watered. The second water of wheat should ensure that there are local conditions, so that the problem of watering the second water can be considered, otherwise it will be in vain to talk on paper. Since we have talked about this topic, today I will talk to you about the best time for the second water of wheat and whether the third water needs to be watered, and explain it in detail.
First of all, the second water of wheat should be based on the actual situation, for example, after watering a water, it can ensure that the moisture in the field is good, which is not necessary to water the second water, but the second water will aggravate the humidity in the field, which will not only increase the infection of powdery mildew and other diseases, but also may aggravate the risk of lodging in the later stage, which is thankless. In addition, the plots with more saline-alkali land may grow worse and worse, and some areas can be watered twice, while in some areas it is watered three times until the wheat is ripe, or even four times or five times.
To put it simply, the second water of wheat is determined by the time of returning to green water or pulling water. For strong seedlings, especially the vigorous wheat field, due to last winter and this spring's rain and snow, the field moisture is good, plus the first water is relatively late (that is to say, watering back to green water is equivalent to pulling water), so that although the wheat jointing period water is sufficiently supplied, but after jointing also pay attention to whether the field water is sufficient.
As the old saying goes, "one water is late, two water rushes, three water sees", the jointing period is the peak period of water demand, followed by the flag picking period, the flag picking period is also one of the key periods in the wheat growth period, the same can not be short of water, if the water supply is insufficient, it will also have a great impact on wheat yield.
In addition, the flowering period of wheat is also the time when a lot of water is needed, which means that the water supply should be sufficient after the wheat is jointed. Because the wheat is followed by the flag-picking boot flowering, these periods have certain requirements for water, so the second water of wheat is recommended to be watered best in this time period, to be precise, it is the best stage from the flag-picking period to the flowering, and it is also the most conducive to the growth of wheat.
Of course, this is only for the wheat area that can be ripened after two waters. For some areas that need to be watered three times, or even more times, it is better to water before the wheat is raised, because the root system of wheat begins to gradually senesce after flowering, especially after flooding, premature aging may occur, which is why some plots are watered after flowering, and the wheat is "ripe", in fact, it is not mature in the real sense, but premature aging.
As for whether or not to pour the third water, it should also be determined according to local conditions. If the field moisture in the wheat filling period is particularly poor, and the rainfall is relatively small in the area, there is no obvious rainfall in the short term, the third water should be watered, so whether the three water needs to be watered should be flexibly selected in combination with the actual local situation.
In closing, I would like to say that there are no hard and fast requirements for wheat watering. Take the second water as an example, if the first water is watered earlier, and now the wheat seedlings in the field are relatively thin and the moisture is poor, watering should be carried out in time when the water source is sufficient. If the second water is relatively late, the field moisture is good, and the field is not dry during the grain filling period, then there is no need to water the third water. Again, if you can ensure that the moisture in the field is good and that the growth of each period is met, you can do it without watering once.
