Detailed Explanation of Seven Key Measures for a Bumper Corn Harvest

1. Correct selection of improved varieties: choose hybrid varieties with high yield potential, sow at the proper time, and plant according to local conditions.

2. Improve sowing quality: use modern single-seed precision planters, appropriately increase the seeding rate, and ensure uniform, complete, and vigorous seedlings.

3. Improve light conditions within the plant population

First, carry out rational close planting according to variety characteristics, soil fertility, and cultivation level; second, adopt strip intercropping and relay cropping to improve light conditions in the middle and upper parts of the plant population.

4. Strengthen fertilizer and water management: adhere to the fertilization principle of "apply sufficient basal fertilizer, lightly apply seedling fertilizer, skillfully apply stalk fertilizer, heavily apply ear fertilizer, and apply grain fertilizer as appropriate," and apply nitrogen, phosphorus, and potassium as well as organic and inorganic fertilizers together to meet the comprehensive nutrient needs of corn at all growth stages.

5. Timely irrigation and drainage: the large trumpet stage and silking stage of corn are critical periods for water demand. Once drought occurs, water should be applied promptly to maintain field water-holding capacity at 70-80%, promoting the differentiation of female and male ears and the formation and development of tassel pollen. At the same time, the flowering and fruiting period of spring corn coincides with the rainy season, and extreme abnormal weather such as heavy rain is very likely to occur. In case of waterlogging, accumulated water should also be drained promptly to promote normal corn growth.

6. Advocate artificial supplementary pollination and detasseling every other row: artificial supplementary pollination is an effective measure to meet the pollen needed by female ears and reduce bare tips and missing grains. Detasseling can reduce nutrient consumption, promote coordination between female and male ears, lessen borer damage, and increase yield, but detasseling should not be done during continuous overcast rain or high temperatures.

7. Pay attention to pest and disease control: in the middle and late stages of corn growth, promptly carry out integrated control of major and minor leaf blights, sheath blight, corn borers, aphids, and other pests and diseases to ensure that corn ears can grow and develop normally.

In corn production, achieving the above seven points can effectively prevent empty stalks, bare tips, and missing grains in corn, thereby achieving the goal of a bumper harvest.
