In the critical period from sowing to the early jointing stage of summer corn, it is essential to focus on effective management of fertilizers and irrigation. As the saying goes, "Three minutes, seven minutes—scientific application of fertilizer and water is key." Practical experience has shown that achieving scientific control over fertilization and irrigation requires implementing the "three attack" method: stem base fertilizer, tassel fertilizer, and grain-filling fertilizer.
The first phase involves applying stem base fertilizer. This occurs during the early growth stage, before the seedlings reach the small bell-mouth stage. At this point, vegetative growth dominates, and for early-maturing varieties, this typically starts at the 5th or 6th leaf stage, while mid-season varieties begin around the 7th leaf. This is an ideal time for fertilization, as the plant is preparing for rapid growth. The amount of fertilizer used at this stage accounts for roughly 30% of the total. Ensuring adequate nutrients and water at this stage helps promote strong, healthy seedling development and sets a solid foundation for future growth.
The second phase focuses on tassel fertilizer, which is applied just before the corn reaches the large bell-mouth stage. This is when the plant transitions from vegetative to reproductive growth. At this point, the 11th leaf is fully expanded, and the plant has reached about 60% of its full size. The tassel begins to develop florets, making it a crucial time for determining the number of ears and potential yield. This stage requires about 60% of the total fertilizer, mainly nitrogen, with some potassium added for balance. If insufficient, the plant may become tall and weak, with small ears and poor yields.
The final phase is the grain-filling fertilizer, applied during the tasseling and pollination period. At this stage, the plant’s stems stop growing, and it enters the reproductive phase. For late-maturing or delayed varieties, this is especially important. A supplementary application of fertilizer at this point ensures the plant has enough nutrients to support grain development. This stage accounts for approximately 20% of the total fertilizer. Proper watering during this time helps maintain leaf function, supporting nutrient transport and storage in the grains, ultimately leading to better grain filling and higher yields.
