Last Updated: 2024/11/05, Corn is a common food crop in China, which is basically planted in every region, and in the northeast, there are subsidies for planting corn on a large scale, so what are the key points of corn cultivation techniques? 1. Seed selection and seed treatment should be based on the local atmosphere as far as possible.

Corn is a common food crop in China, which is basically planted in every region, and in the northeast, there are subsidies for planting corn on a large scale, so what are the key points of corn cultivation techniques?

1. Seed selection and seed treatment

When selecting seeds, try to select suitable seeds according to the local climate, generally use drought-resistant compound seed coating agent to coat maize seeds to enhance root vitality and self-stress resistance, and improve seed water absorption and water retention. After selecting the seeds, soak the corn seeds in 20-25 ℃ warm water for two days and nights, then dry and sow them to improve the ability of drought resistance. The method of soaking seeds with chemicals also has a good effect on drought resistance and seedling protection of maize.

2. Land preparation

Straw mulching and other methods are used to reduce water evaporation, preserve air precipitation and improve soil moisture.

3. Sowing seeds

Sow seeds at the right time according to local conditions. Generally, when sowing, the density should be appropriate, and each cave can sow two or three seeds.

4. Management technology after sowing.

The main results are as follows: (1) Formula fertilization: increase the application of organic fertilizer and combine with chemical fertilizer to transfer water with fertilizer, coordinate water and fertilizer and improve water use efficiency.

(2) suitable interplanting: making use of the characteristics of drought tolerance in maize seedling stage, interplanting in wheat field can basically meet the water demand of maize growth and development. Applying organic fertilizer in furrow, applying organic fertilizer to preserve soil moisture, interplanting corn in wheat field and covering wheat straw between rows play an important role in saving water, preserving soil moisture and improving soil fertility.

(3) strengthen field management: loosen soil frequently, weed, improve soil permeability, increase soil microbial activity, reduce surface water evaporation and surface runoff, so as to promote root growth and improve drought resistance of maize.
