In the spring corn growing season, meteorological disasters are frequent, especially severe storms and prolonged rainfall, which often lead to lodging, stem breakage, and waterlogging—major threats to corn development. After such events, immediate remedial actions are essential to help crops recover and minimize yield losses.
First, timely earthing up is crucial. During the jointing and maturing stages, heavy storms can cause corn stalks to bend or fall over. If not addressed promptly, the plants may intertwine, significantly reducing photosynthesis and causing substantial yield loss. Once the rain stops, it's important to straighten the plants and mound soil around the base of the stems, compacting it with your feet. This helps the corn grow new roots within 2–3 days, quickly restoring growth with minimal impact on production. In the early jointing stage, if a storm threatens but the lodging angle is less than 45 degrees, the plants can naturally recover after 5–7 days without intervention.
Second, for severe lodging, bundling multiple plants together can be effective. Tall corn varieties are particularly vulnerable during the grain-filling period, as heavy rain can cause them to fall completely, leading to broken stems and major yield loss. In such cases, mounding soil isn't effective, so farmers should bundle 3–4 nearby plants together. This allows them to support each other, preventing further damage and helping the ears mature more evenly, thus reducing overall yield loss.
Third, drainage is critical. Spring maize is often grown in regions with heavy rainfall, and excessive precipitation can lead to water accumulation in fields. High soil moisture can suffocate roots, impairing their function and ultimately reducing yield. After the rain, it’s important to clear ditches, furrows, and drainage channels to lower the water table and reduce soil saturation. Low-lying areas and paddy fields are especially prone to waterlogging, making drainage even more vital. Studies show that even a few days of waterlogging during the tasseling stage can significantly reduce yields—up to 20% after three days, and 40% after four to five days. Therefore, prompt drainage is key to protecting crop health.
Fourth, strengthening field management is essential after a storm. Damaged corn needs careful attention to restore its growth and improve photosynthetic efficiency. Timely cultivation, loosening the soil, and removing compaction can enhance root activity and promote recovery. Depending on the severity of the damage, applying additional nitrogen fertilizer can also help speed up plant growth and recovery. These steps are vital in ensuring that the crop regains its productivity as quickly as possible.
Imported Premium Antistatic Agent
Antistatic agents are additives added to plastics or coated on the surface of molded products to reduce the accumulation of static electricity. Usually according to the use of different methods, antistatic agents can be divided into two types of internal and external coating, plastic is mainly used in the internal antistatic agent. According to the performance of antistatic agents can also be divided into temporary and permanent two categories.
