E: the first ten days of a month; M: the middle ten days of a month; L: the last ten days of a month (Adopted from Han et al., 2022) 7 Concluding Remarks Properly adjusting sowing time, choosing the right varieties, and using sowing methods are effective ways to increase corn yields and benefits. Many studies have found that these practices can help farmers reduce the risk of yield reductions caused by climate change. For example, in Northeast China, if the sowing period can be adjusted and the right varieties can be rotated, corn yields can be increased by up to 42.7%. The increase in yields in the entire corn-growing area may also be between 11.1% and 53.9%. If sowing optimization is combined with nitrogen fertilizer management, ridge planting, mulching and other technologies, yields can be further improved, incomes can be higher, and the impact on the environment is reduced. Now, many new seeders are equipped with intelligent functions, such as automatic adjustment of sowing depth and monitoring of soil moisture. These devices can help corn seedlings emerge more evenly, improve drought resistance, and save water and fertilizer. By analyzing real-time data and using model predictions, farmers can flexibly adjust sowing time and input according to the situation of each plot of land, thereby achieving higher yields and more reasonable resource utilization. Considering that the rural labor force is decreasing, such technologies are becoming more and more important. They can not only improve work efficiency, but also reduce labor costs. Looking ahead, continuing to promote intelligent seeding systems, using data for precise management, and combining local seeding methods and varieties with strong stress resistance will be an important means to cope
