When is the jointing stage of wheat? How to promote wheat growth at jointing stage?

The jointing stage of wheat is generally around March 20 every year, that is, when the basal internodes of wheat are about 2cm above the ground, they enter the jointing stage. From jointing stage to heading stage, the growth rate of wheat is relatively fast. In order to improve the ear yield and seed setting rate, according to the growth of wheat, wheat can be "hung with paper money" and "covered with wheat in summer" for exactly one month. Another month, this wheat month is a node. It is one month from turning green to hanging paper money, another month from hanging paper money to shaving, and another month from yi tooth to cutting wheat.

The amount of watering should be determined according to the soil moisture in the field. Just keep the soil moist, which can promote the elongation and thickening of wheat plants, and it is not necessary to water if there is no drought. If the humidity in the field is too high, the harm of pests and diseases will increase, which is not conducive to the growth of wheat. The greening period of southern wheat is about half a month earlier than that of northern wheat, and the greening fertilizer is applied from the end of February to the beginning of March, and northern wheat may be applied from the end of March to the beginning of April. With regard to the "get up" wheat, spring began, and the southern wheat began to resume production, and the weather gradually warmed up.

Wheat generally starts jointing around Tomb-Sweeping Day, and gradually jointing a little as the weather gets warmer. At this time, weeding, fertilization and irrigation should be started. By mid-June, there was a bumper harvest. We are bordered by Tengger Desert in the east and Qilian Mountain in the west. The sunshine is strong, the temperature difference between day and night is large, and the time gap between plain planting and mountain planting is also large. The growth cycle and length of wheat directly determine the quality. Short-term quality of wheat in mountainous areas does not tumble. Winter wheat is rarely planted, and it is sown around the autumnal equinox.

The jointing stage of wheat turning green is one of the key nodes in wheat management, which determines the number of ears per mu of wheat and is also the key period to prevent lodging, sheath blight, rust and powdery mildew. According to the difference of temperature and sowing date in previous years, wheat started jointing from the end of February to the beginning of March, and entered booting stage around mid-April. So at this time, you can go to the fields in time to see the wheat.
