Which month is suitable for planting corn?

Corn is not only a key source of food and feed in China, but also is hailed as a product for health and longevity due to its rich nutrients such as protein, vitamins and cellulose. It has extremely high agricultural planting value. So which month is suitable for planting corn?

Which month is suitable for planting corn?

The best time to plant corn varies depending on regional climate conditions. The following are corn planting time references for some regions:

Northern region: Generally sowing is done from mid-to-late April to early to mid-May.

Southern region: Spring corn is generally planted from late March to early April.

Huanghuai and Haihe regions: Spring corn is usually planted in late April to early May, while summer corn is planted after winter wheat is harvested, around June.

Northeast region: Spring corn sowing time is generally after Grain Rain (April 20) and before May 10.

Hebei region: Spring corn is sown in late April to early May, and summer corn is sown in early to mid-June.

Anhui area: Spring corn is generally planted in mid-to-late April, and summer corn is planted in early to mid-June.

Generally speaking, you can start sowing when the local temperature stabilizes at 10-15 degrees Celsius. When sowing, the sowing density should be determined according to the characteristics of the variety and the conditions of the land. In addition, the suitable time for sowing is when the temperature of the top 5 to 10 cm of soil is stable at above 12°C. Before sowing, ensure that the soil moisture is appropriate, and the optimal soil moisture content is 60-70% of the field capacity.

Corn growth cycle

Seedling stage: From sowing to jointing, this stage is mainly about the growth of corn roots, stems and leaves, and is the nutritional growth stage. Corn in the seedling stage requires relatively little water and nutrients, but has certain requirements for soil temperature and humidity. Corn is more drought-resistant in the seedling stage.

Ear stage: From jointing to tasseling, the vegetative growth and reproductive growth of corn proceed simultaneously during this stage, which is the most vigorous period of corn growth and development. At this stage, corn needs more nutrients and water, especially phosphorus and potassium.

Flowering and grain-forming stage: From tasseling to maturity, the main growth activity of corn at this stage is the filling and maturation of grains. During this stage, corn's demand for water gradually decreases, but its demand for nutrients remains high, especially nitrogen fertilizer.

The growth cycle of corn is about 100-150 days, depending on the variety and climatic conditions of the planting area. The growth cycle of early-maturing varieties is shorter, about 80-100 days; the growth cycle of mid-maturing varieties is about 100-120 days; and the growth cycle of late-maturing varieties is about 120-150 days. In actual planting, the specific sowing and harvesting times should be determined according to local climatic conditions and variety characteristics.

The above is an introduction to the corn sowing time. When planting corn, you must choose suitable varieties based on the environmental and climatic conditions of the planting area.
