First, when using green chopped corn machinery, it's best to choose mature varieties with green stalks. These stalks are crisp and easy to cut into small pieces. For dry corn stalks, it’s recommended to chop them twice or leave the whole plant in the field. Manual chopping and returning the stalks to the field is also an option. The ideal length for the chopped stalks is around 5 cm, which helps in better decomposition and soil integration.
Second, it's important to remove the corn husks and cob before processing. It’s advisable to take the husks out of the field because they are soft and fibrous, making them difficult for shredders to handle. They can easily wrap around the blades, reducing efficiency and causing unnecessary wear on the equipment.
Third, after returning the corn stalks to the field, make sure to water the area adequately before planting wheat. Timely sowing of wheat helps establish strong seedlings. To avoid weak growth due to either overwatering or under-watering, it's essential to maintain proper moisture levels in the soil.
Fourth, ploughing and crushing the corn stalks in the field should be done evenly. Large tractors are suitable for deep ploughing, while smaller tractors can be used for surface leveling. Ensure that no straw remains on the top 10 cm of soil to guarantee good seed-to-soil contact and improve the quality of the next crop’s planting.
In addition, proper management of crop residues not only improves soil fertility but also supports sustainable farming practices. By following these steps, farmers can maximize the benefits of corn residue return while preparing the land for the next planting season effectively.
