1. **Ditch System Maintenance**: After transplanting, it's crucial to clear the ditch system immediately to ensure proper drainage during rain and irrigation during dry periods. This helps maintain the smooth operation of the three channels—drainage, irrigation, and water flow—ensuring optimal growing conditions for the crops.
2. **Shed Cultivation Management**: Monitor and adjust the temperature inside the greenhouse regularly. On rainy days, keep the shed closed to protect the seedlings. During sunny days, ventilate for about an hour at noon. In the afternoon, from 12 PM to 3 PM, you can partially open the windward side to avoid overheating. Once the plants reach 60 cm in height, usually around late April, remove the small ring sheds to promote better growth.
3. **Joint Fertilization**: Apply fertilizer after the corn has formed its first joint, typically when it has 6 to 7 leaves. Based on soil fertility and plant development, apply 7–8 kg of urea per acre to support rapid growth and strengthen the stalks.
4. **Drought Resistance Measures**: After the jointing stage, corn enters a critical growth period, especially before and during tasseling. If drought occurs, implement timely irrigation by furrowing at night when temperatures are cooler, and drain excess water before sunrise to prevent waterlogging.
5. **Panicle Fertilization**: During the booting stage, when the plant is transitioning from vegetative to reproductive growth, apply 15–20 kg of urea per 666.7 m² when the plant has 12–13 leaves (commonly known as the "big bell mouth" stage). This ensures adequate nutrients, reduces spikelet loss, and prevents barren ears.
6. **Tassel Removal (Castration)**: Removing tassels helps reduce nutrient competition and improves air circulation and light penetration. The extent of removal depends on weather and plant condition. On sunny days with uniform growth, remove tassels when they first appear. Otherwise, limit or skip the process.
7. **Removing Extra Ears**: Waxy corn often produces multiple ears, but only the top one should be kept. After the lower ear starts silk production, remove the extra ones to allow the plant to focus energy on one strong ear. Be careful not to damage the leaf sheaths during this process.
8. **Timely Harvesting**: Harvesting at the right time ensures high-quality fresh ears. The best time is usually 22–24 days after pollination, when the kernels are still milky and flavorful. Different varieties may have different timelines based on accumulated heat and maturity. In hot or dry conditions, harvest earlier to avoid quality loss.
