After the low temperature, the weak seedlings and the stiff seedlings were transformed into strong seedlings. The normal growth was rapidly restored and the jointing and heading were advanced earlier. This was the most mentioned management goal in the main winter wheat production areas in northern China after winter and spring continued low temperatures. Now wheat growth has entered the heading period, which is the key period for determining the level of yield. With the increase of temperature, pests and diseases will also enter the multiple period. Therefore, in the early stage of wheat recovery and management, the management of wheat should be strengthened. In the later stage of wheat management, the main promotion is to raise roots and protect leaves, regulate plant hormone levels, increase root absorption nutrients, promote young ear differentiation, promote heading, increase grain filling strength, prevent premature aging, and increase grain weight.
After the jointing of wheat, the ability of cold resistance significantly decreased, and the influence of frost damage on night frost should be strengthened to prevent the plants from being damaged again. The spraying of Shuofeng 481 and high-energy red potassium on the plants that are still very weak in the seedlings can rapidly restore the normal growth of the plants, and timely supplement the nutrient requirements for roots to absorb nutrients from the leaves in a timely manner, stout stems, promote young spike differentiation, and effectively resist late frost. Again affected.
The control of pests in the late stage of wheat growth, especially at the ear stage, is critical. Last winter's weak seedlings overwintering, coupled with continued low temperatures this spring, plant resistance to disease decreased significantly, once the temperature rises rapidly, rust, powdery mildew, panicle blast, spider mites, etc. will occur in a large area, pest damage directly caused by a thousand grains The decline will seriously affect wheat production. In the panicle stage, we can use imidacloprid + "Pingxing" + Shuofeng 481 to prevent and treat diseases such as wheat ear, rust, etc. Spraying together with high-energy red potassium can rapidly supplement potassium-based nutrient requirements and make the field grow evenly. The heading is orderly, the seed fertility rate in low temperature and rainy climate is improved, the premature aging is prevented, the ability of plants to resist dry hot wind is improved, the resistance of plants is enhanced, and the effect of chemical control is enhanced.
