One is anti-falling   When corn seedlings are too dense, and irrigation and fertilization are not properly managed during the stem elongation phase, it can lead to lodging, which negatively affects yield. To prevent this, it’s important to deepen the soil cultivation layer, apply sufficient base fertilizer, and perform proper field cultivation to ensure strong and stable growth. During fertilization, a balanced mix of nitrogen, phosphorus, and potassium should be used, while maintaining an appropriate plant density to allow enough sunlight for the leaves. This helps develop thick and sturdy stalks, increasing resistance to lodging.

      Second, the air defense stalk   Insufficient mineral supply or poor nutrition during the ear differentiation stage can lead to empty stalks. This often happens when the planting density is too high, causing weak photosynthesis and deficiencies in nitrogen, phosphorus, and potassium. To address this, it's crucial to maintain proper spacing between plants so that they have adequate ventilation and light. Timely nutrient and water supply supports ear development, and a balanced application of the three essential nutrients is necessary. In low-fertility soils, more organic fertilizers should be added, while in high-fertility soils, extra fertilizers at the seedling stage help build strong roots and stalks. If plants are too dense or weak, they should be removed promptly.

       The third is anti-bald   A lack of phosphate fertilizer in the soil can cause issues during the booting stage, such as impaired sugar metabolism and protein synthesis, leading to shrunk ears and delayed silk elongation, which affects natural pollination. This results in baldness or even empty ears. If potassium is lacking, it hinders the transport of carbohydrates to the grains, reducing starch accumulation. Additionally, early insect damage, wind, or rain during flowering can block pollen fertilization, causing similar problems. To prevent these issues, it’s important to manage pests, apply more phosphorus and potassium fertilizers, and ensure timely watering during the tasseling stage. Artificial pollination during flowering can also improve results.

      Fourth is anti-premature aging   Corn plants are tall and consume a lot of nutrients and water during growth. Excessive moisture can reduce oxygen in the soil, weakening root activity and making it harder for plants to absorb water. On sunny days, transpiration increases, leading to metabolic imbalances, curled leaves, and stunted growth. If there is a lack of nutrients at this stage, plants may become short and even die. To prevent premature aging, proper drainage is essential in rainy areas. If leaves start to yellow or show signs of aging, applying refined fertilizers or spraying phosphate solutions during early flowering can help prolong leaf life and increase ear production. Applying ash or potassium sulfate at the seedling stage can also help prevent early aging. (Gansu Science and Technology News Cheng Yanli)
