Is it early to water the wheat in rainy season?

The frequency of wheat irrigation depends on the local soil natural environment and drought degree. Generally speaking, it is best to water wheat three times to get it. My hometown is in Shandong province. In recent years, there has been little rain and a little drought in my hometown. In some cases, there was a heavy rain, which was lost all spring. The more crops need water, the more there is no rain, and there is no way but to water them by manpower. The first watering was more than a month later, when the ambient temperature gradually increased.

Wheat is gradually turning green, and there must be a certain amount of water and fertilizer to ensure its growth and development, so as to grow solid and vigorous. If it snows a lot in winter and there is precipitation in spring, and the wheat seedlings are in good condition, you can water them later. If spring falls from the sky and there is enough rainfall, it is really eye-catching in the sky. For ordinary people, it is cost-effective and green water can stop. But the rainfall in spring is generally not easy to be large, because "spring rain is as expensive as oil". The second watering is at the heading and booting stage of wheat. At that time, wheat grew faster and needed a lot of water to ensure it.

However, it is not advisable to have too much water at the early heading stage, otherwise it will easily lead to vigorous growth and germination of wheat. ? In April, wheat entered the heading and jointing stage, which is a key period for wheat growth and development. For the overall rise of wheat, water injection and fertilization should be immediately carried out at the heading and jointing stage of wheat to promote the heading and jointing stage of wheat and achieve stable and high yield. According to the rising trend and seedling situation of wheat, heading and watering should be carried out in the middle and late April. Everyone's local wheat is usually obtained around June 10.

Grouting and watering are generally carried out in the middle and late May. After the wheat entered the filling stage, the outside temperature was high, the water surface evaporated greatly, and the wheat consumed a lot of water. If there is a premise, watering the wheat once at this time is beneficial to wheat filling and improving wheat density. However, attention should be paid to grouting water to minimize flooding, which is very easy to cause wheat seedlings to lodging. It is best to use sprinkler irrigation equipment. In addition, the continuous high temperature period should be avoided at that time to prevent wheat wilting.
