Corn is one of the most important food crops in the world, which is widely distributed in the United States, China, Brazil and other countries. Corn likes warm environment, and its growth temperature needs to be controlled at around 25℃. It is necessary to provide enough water to keep the soil moist during the growing period. Provide enough light every day to promote the photosynthesis of plants.
Compared with traditional food crops such as rice and wheat, corn has strong drought tolerance, cold tolerance, barren tolerance and excellent environmental adaptability. Corn seedlings are sown in the three-leaf stage, and seedlings can be fixed according to plant spacing when the leaves are five. It is necessary to pull out sick seedlings, weak seedlings and exotic plants and leave strong seedlings; In case of lack of seedlings and broken ridges, two seedlings should be left beside. Timely intertillage after seedling establishment, clear ridges and stubble, and promote solid root system.
Corn planting environment
Corn is suitable for growing in a warm environment, and the optimum germination temperature of its seeds is about 28-35 degrees, and the optimum temperature of flowering period is about 25-26 degrees. When cultivating corn, it is necessary to accelerate the germination of its seeds. The corn seeds can be placed in an environment of about 30 degrees to improve their germination rate.
Corn is a short-day plant. When planting corn, if the illumination time is too short, it will slow down the growth rate of plants and thus reduce the yield of corn. Corn should be planted in sunny soil and exposed to 8- 10 hours of natural light every day to promote the healthy growth of corn.
Corn plants are tall. They need more water. The most suitable precipitation is between 465,438+00 mm and 640 mm. When planting corn, if the water is insufficient, it is necessary to water the plants to prevent the corn from drying up. In the rainstorm season, the accumulated water in the soil should be drained for the corn.
