Planting a piece of wheat, how to judge whether the wheat needs watering?

Let me talk about our situation here! We belong to semi-arid area here. When wheat was sown, the soil was already dry and the soil moisture was insufficient. Wheat germinated several days after sowing, but according to the weather forecast these days, it turned sunny to cloudy and farmers began to water it.

Don't water the wheat seedlings after they come out, depending on the soil moisture and the weather forecast for the next few days. Sprinkle water before sowing, and the soil moisture will be ok after the wheat seedlings come out. Wait a few days and pay attention to the weather forecast. It's not too late to water them.

If the soil moisture is not good before sowing, the weather is dry after sowing, and the wheat has sprouted and taken root, it is necessary to water it as soon as possible and prepare for irrigation. After wheat germination, the water is seriously insufficient, the wheat seedlings will turn yellow, and the nutrient absorption will be affected, resulting in less flour and insufficient wheat seedlings in the field, which will have a great impact on next year's yield.

After the wheat seedlings come out, the water is insufficient, and the wheat seedlings are about 7 cm long. Irrigation with a small amount of water can ensure the whole seedling. After watering the land, plough it with hoes to prevent soil hardening and soil moisture. When wheat is sown, the soil is soft and large, and it is easy to run. In winter, the drought is serious. If the whole seedling is watered once, the soil will be broken and everywhere, and the compression will avoid the East China Sea. After the wheat seedlings come out, water them once in drought, and you can get water to pull them out. The nutrition is fully absorbed, deeply rooted and abundant, which lays a good foundation for wheat seedling development, drought resistance and cold tolerance in Miao Zhuang and wheat turning green next year.

The drought is more obvious this autumn. For example, the continuous rainy weather in autumn last year seems to be gone forever this year, and it seldom rains after wheat is sown in the middle of 5438+ 10. Even from now on, some friends expect that wheat production will drop. However, the scientific development of agriculture believes that it may not be enough to judge whether to reduce production next year by referring to dry weather at this time.

Although the weather is dry now, wheat production in major wheat producing areas such as Henan, Shandong, Hebei and Shanxi has sprouted. It can't be said that wheat is growing well, but the density is not too bad now. Do you want to water it now?

Judging from the current weather, it doesn't seem to rain recently, but there will be frost weather in the north soon, so we should consider paying taxes as soon as possible. But now the wheat is sprouting. In other words, the soil moisture is enough to ensure that wheat is unearthed. With the gradual growth of wheat roots, science promotes agriculture. I believe that the development of wheat will be more solid in the future, and it seems that it is not too dry now. In fact, there is almost no need to consider taxes.

The weather is getting colder and colder, and the yield-increasing effect of wheat leaves is also weak. At the same time, at present, the growth of wheat is slow, and there is little demand for water and fertilizer. Therefore, the viewpoint of scientific development of agriculture is to consider watering again in the near future unless the soil is particularly dry. Otherwise, it really doesn't need much. If it is really necessary to water, science promotes agriculture and thinks that irrigation or watering can be considered, and remember not to flood. Otherwise, the ground is too wet and it is easy to cause the East China Sea in winter. In addition, if there is enough water in the early stage, it can ensure better development at seedling stage, improve the disease resistance and cold resistance of wheat plants, and achieve the goal of strengthening seedlings at seedling stage.

Of course, it won't be necessary if it rains recently. Mild drought can promote the growth and development of wheat roots, and wheat itself has strong tillering ability. In the spring of next year, when there is enough water, tillers will increase, and vigorous roots will not cause yield loss.

Wheat grows slowly before the Spring Festival, but field management at this stage is also very important. Seedling management is the basis of harvest, but due to the special weather this year, soil drought will weaken the growth momentum of seedling, and excessive humidity in the field will lead to the East China Sea. The humidity in the field still needs attention. How to master this measure, we should observe more in the field and grasp the growth of wheat in the field in time.
