Corn planting technology and management fertilization

When planting corn, we should choose varieties with strong lodging resistance and high yield, then sow corn seeds in loose and fertile soil and water them again to make corn germinate quickly. When the corn grows to 3-4 leaves, phosphorus and potassium fertilizer should be applied topdressing to provide the nutrients needed by the plants.

Corn 1 How to Plant and Variety Selection

When planting corn, we should choose mid-late maturing varieties with high yield, large panicle type and strong disease resistance, and the varieties should have the advantages of strong lodging resistance and compactness. It is best to choose Nongda 108, Huanong 10 1, Zhongdan 909 and Baoyu 1, which is beneficial to increase corn yield.

2. Planting method

When planting corn, it is necessary to apply nitrogen, phosphorus and potassium compound fertilizer in the soil, then sow corn seeds in the soil, and then water it once to make the corn absorb enough nutrition and water, and cover the soil surface with plastic film to raise the soil temperature and increase the germination rate of the corn.

3. Fertilization management

Corn is a fertilizer-loving plant, and it needs sufficient nutrients during its growth. When planting corn, it is necessary to apply phosphate fertilizer and potash fertilizer as topdressing when the plant grows to 3-4 leaves, so as to accelerate the growth of corn, and apply decomposed organic fertilizer to it at the fruiting stage to maintain the normal growth of corn.

4. Maintenance management

When maintaining corn, it is necessary to observe the growth state of the plant regularly. If there are pests on corn leaves, pull out the seriously infected seedlings to avoid large-scale infection, and spray 1-2 times every other week to eliminate the pests on corn leaves and make them grow healthily.
