When is the end of the wheat jointing season?

Is the jointing period of wheat calculated by time or from a few leaves? When will it end? During the seedling stage of wheat, the internodes of the seedlings are not drawn long, and multiple leaf segments grow together to form a shortened stem segment. When sowing is deep, the hypocotyls or the hypocotyls will grow long enough to form the underground elongated section, but when the tillers show their ground, they no longer draw. Generally until the spring, the fresh start of the wheat base begins to grow and enter the jointing period. In Yizheng and other places, more spring wheat varieties are planted, and the main stems generally have five long-barreled sections, the lower ones are shorter and the upper ones are longer. There is a certain degree of synteny between the length of the wheat internodes and the length of the leaves, and there are five wheats in the main stem, which are usually grown during the first three leaves. When the wheat began to be jointed, the morphological performance was obvious. The production can be judged whether the wheat seedlings enter the jointing stage by peeling and checking whether the length of the main stem base of the wheat seedlings is lengthened. The internodes of wheat grow long and continue until the ears are completely extracted. Yizheng and other places plant more spring wheat varieties. When the main stem begins to be jointed, the main stem growth point begins to enter the stage of ear differentiation, and when the main stem has two long stems, it can be peeled off to find large rice grains. Young ears. Generally, when the wheat flag leaves are pumped, as the young panicles increase, the appearance of the booting position can be obviously bulging. At this time, the wheat enters the booting stage. Production usually starts from jointing to booting. This period of time is known as the jointing period of wheat. This period is the period of vegetative growth and reproductive growth of wheat. After entering the booting stage, wheat is dominated by reproductive growth.
