How to Grow Corn? A Detailed Explanation of the Key Points of Corn Cultivation Techniques
Corn is a common grain crop in our country, basically grown in every region, and in the Northeast region, large-scale corn planting even comes with subsidies. So what are the key points of corn cultivation techniques?
1. Seed selection and seed treatment
When selecting seeds, try to choose suitable seeds according to the local climate. Generally, drought-resistant compound seed coating agents are used to coat corn seeds, enhancing root vitality and their own stress resistance, and improving the seeds' water absorption and retention capacity. After selecting the seeds, soak the corn seeds in warm water at 20-25°C for two days and nights, then remove them, dry them, and sow, to improve drought resistance. The chemical seed soaking method also has a good effect on drought resistance and seedling preservation in corn.
2. Land preparation
Use methods such as wheat straw mulching to reduce water evaporation, retain atmospheric precipitation, and improve soil moisture.
3. Sowing
Adapt to local conditions and sow at the right time. Generally when sowing, the density should be appropriate, and sowing two or three seeds per hole is sufficient.
4. Post-sowing management techniques
(1) Formula fertilization: Increase the application of organic fertilizer and apply it together with chemical fertilizer, thereby achieving the regulation of water through fertilizer, coordinating water and fertilizer, and improving water use efficiency.
(2) Timely intercropping: Taking advantage of the relatively drought-tolerant characteristics of corn at the seedling stage, implement intercropping in wheat fields, so that the water demand pattern of corn basically matches natural precipitation, which can basically meet the water needs of corn growth and development.Applying organic fertilizer in furrows to preserve moisture. Intercropping corn in wheat fields and covering the corn rows with wheat straw play an important role in saving water and preserving moisture and improving soil fertility.
(3) Strengthen field management: frequently loosen the soil, remove weeds, improve soil aeration, increase soil microbial activity, reduce ground water evaporation, reduce surface runoff, so as to promote root growth and improve the drought resistance of corn.
