Autumn corn planting time in the south

In the south, autumn corn is generally planted from late June to mid-July, and no later than mid-July. Otherwise, the taste and yield of the corn will be affected due to changes in climatic conditions.

How to Plant Autumn Corn in the South

1. When selecting seeds, you should choose seeds with full grains and luster. Place the seeds in the sun to dry. You can also use relevant chemical agents to soak them for germination. The treated seeds are easier to germinate after sowing.

2. Plough and harrow in time, and carefully prepare the land to make the soil loose, fine and flat, so as to create a good environment for seed germination and emergence. It is also necessary to dig drainage ditches to prevent soil waterlogging and compaction that cause seed rot and seedling shortage. After the preliminary work is done, sow seeds in time. It is ideal to sow autumn corn in early to mid-July (that is, during the period from Lesser Heat to Greater Heat), and no later than the end of July.

3. After sowing, pay attention to water and fertilizer management. Water twice a day at 10 am and 1 pm. Be sure to water thoroughly. Corn growth has high nutrient requirements. Nitrogen fertilizer should be used mainly, supplemented by phosphorus and potassium fertilizers, and topdressing should be carried out according to the condition of the corn plants.

Key Points for Planting Autumn Corn in the South

When planting autumn corn, you must pay attention to the planting density. Generally, about 4,000 corn plants should be maintained per acre during the planting process. The root system of autumn corn is not well developed in the seedling stage, and the planting period is in the rainy season. Water is easily accumulated in the field, affecting the growth of seedlings. Attention should be paid to timely drainage after rain.
