Corn acre yield is usually 800-1200 pounds.

Normally, corn can produce about 1,200 pounds per acre, or about 1,500 pounds if it's in a region with longer and warmer sunshine hours. Specific mu yield and varieties, planting season, soil fertility, management style and other factors related to the development of the root growth of corn, the higher requirements of the soil, suitable for planting in the soil deep, fertile drainage of the plot.

Transplant seedlings between seedlings after they grow out, and provide sufficient water and fertilizer during the period of nodulation, the big trumpet period, and the peak of grouting. Corn different growth period for different temperature requirements, corn sowing to seedling growth temperature can not be lower than 6 ℃ -7 ℃, suitable for the growth of the temperature is 10 ℃ -12 ℃, the fastest germination is in the temperature of 28 ℃ -35 ℃.

Methods to increase corn yield:

1, Shi Aspirin

The chemical name of aspirin is ether salicylic acid, which can be decomposed into salicylic acid and acetic acid in water, and enter the plant body can reduce water transpiration, thus resisting drought. Corn before sowing with 0.05% to 0.1% aspirin water solution soaked seeds, can improve seedling emergence rate of 15% to 18%, yield increase of 6% to 8%.

2, apply rice vinegar. The main component of pure rice vinegar is acetic acid, which is indispensable for crop absorption and metabolic action. Before sowing corn with 0.05% of pure rice vinegar liquid soak seeds for 24 hours, fish out, smother seeds 3~4 hours after sowing can increase yield 1 6%; draw male before spraying 300 times of pure rice vinegar liquid can increase yield 15%.
