After the spring, with the temperature rise, wheat growth has entered an important turning point. It is a crucial period for winning more spikes, growing ears, increasing grain weight, setting up high-yielding seedlings and capturing high yield. Wheat spring management, must be combined with the years before the Miaoqing looks. According to the characteristics of spring wheat growth and soil, climate and other conditions, so that due to vaccine system, classification management, to promote the balanced growth of wheat, wheat won the full harvest. First, weak seedlings management Weak seedlings to analyze the formation of the reasons, according to different circumstances, to take appropriate management measures. 1. The lack of soil fertility formed weak seedlings of such wheat seedlings less tiller years ago, underdeveloped roots, narrow leaves, small groups, the number of seedlings
