Spring is the period of strong winter wheat growth. The following five management points must be known!
The weather is getting warmer and warmer, the temperature is getting higher and higher, winter wheat has returned to green, and after winter hibernation in winter wheat, spring management is very important. This has a great impact on the yield and quality of wheat. How do you manage winter wheat in the spring? Let's take a look at it.
First, timely topdressing
Wheat will be topdressed and chased by the growth of wheat before wintering, but after a whole winter's dormancy, winter wheat needs a lot of water and nutrients to get better greening, so it should be based on wheat after wheat is greened. The growth of the topdressing, topdressing fertilizer can not be used to promote the growth of wheat, but according to the growth of wheat, urea and diammonium phosphate to control the growth of wheat, so that wheat is timely tillering to reduce the impact of cold spring on wheat. In addition to topdressing in the spring when the wheat is green, it is also necessary to apply urea at the jointing stage of wheat to promote wheat panicles and flowering.
Second, timely watering
In addition to timely topdressing when the wheat is greened, it is also necessary to choose not to water according to the wheat sensation. For wheat fields with poor grievances, water is replenished in time to replenish the water of wheat after thawing, and watering can also increase soil temperature and prevent freezing damage. For wheat fields with good grievances, they can be repressed in time after thawing to bridge the cracks frozen in winter days, reduce soil water evaporation and promote wheat development.
Third, prevent freezing damage
In spring, it is easy to fall cold. In recent days, the temperature has dropped drastically. It is easy to frostbite wheat when the temperature drops suddenly. Therefore, pay more attention to weather changes in the spring, and timely watering before the strong temperature drop to increase the ground temperature and reduce the occurrence of frost damage. After wheat frostbite, it can be explained that wheat with a small amount of nitrogen fertilizer and irrigation to promote frostbite returns to normal growth.
Fourth, prevention and control of pests and diseases
Spring blossoms are not only the rapid growth of crops, but also the season when pests and diseases begin to breed. Therefore, in high-incidence areas where pests and diseases occur, insecticides and fungicides can be sprayed in the spring to reduce the occurrence of pests and diseases.
5. Scientific and effective weeding
In the spring, when the wheat is topdressed and fertilized, the weeds will have sufficient water and nutrients to grow rapidly. The weed growth will not only compete with the wheat for nutrients, but also reduce the yield of wheat. The pests and diseases on the weeds will spread. On wheat, so after the temperature in the spring reaches 6 degrees, the herbicide can be sprayed according to the type of weed in the wheat field. It should be noted that the concentration of the herbicide and the spraying time should be scientifically used to avoid phytotoxicity.
Spring can be said to be the rapid period of wheat growth. At this time, wheat management must be done to ensure the yield and quality of wheat later!
