5.1. Conclusions
- (1)
- The carbon footprint of maize cultivation in the orthogonal experimental group using cleaner production technologies was generally higher than that of the traditional control group, which showed that the application of cleaner production technologies in the black soil regions is crucial for increasing production and reducing carbon emissions and that fertilizers, diesel fuel, and direct emissions of N2O from farmland are the three main sources of carbon emissions from maize cultivation in China’s black soil regions; future focus should be placed on these three aspects to further improve maize cultivation’s carbon footprint in black soil regions.
- (2)
- The production efficiency of each experimental group of cleaner production technology for maize cultivation in China’s black soil regions showed an overall upward trend and was higher than that of the control group, but none of them reached DEA effectiveness. The uncoordinated development of technical efficiency and the rate of technical progress are the most important reasons for low production efficiency.
- (3)
- According to the efficiency evaluation matrix of orthogonal experimental groups for cleaner production of maize cultivation in black soil regions, the integrated technical efficiency and total factor production efficiency of test group F1I2S2 in semi-arid black soil regions and test group T2F1S2 in semi-humid black soil regions were relatively optimal.
5.2. Recommendations
- (1)
- Close attention should be paid to the combined impact of carbon emissions and carbon sequestration on the carbon footprint of the black soil region, and through the application of a reasonable combination of cleaner production technology modes, the excessive carbon emissions caused by the redundancy of agricultural material inputs during the reproductive period should be reduced. At the same time, a sound system of emergency management should be established for stable production and security of supply to enhance the degree of carbon sequestration.
- (2)
- Focusing on the innovation of cleaner production technologies, strengthening technology diffusion, and bringing into play the synergistic effect of technological progress and enhancements in technological efficiency is crucial in accelerating the construction of low-carbon, high-yield, and sustainable maize cultivation.
- (3)
- In semi-arid black soil regions, efforts should be made to demonstrate and promote the integrated model (F1I2S2) of “Soil testing and formulation + Full mobile sprinkler irrigation + Straw tilling and field return” technology, which, together with effective yield-enhancement measures such as precision sowing, chemical control and anti-fall, and biological control of pests and diseases, can effectively enhance the low-carbon productivity of maize by 20.3%. In semi-humid black soil regions, efforts should be made to demonstrate and promote the “No tillage in spring + Soil testing and formulation + Straw tilling and field return” technology integrated model (T2F1S2) supplemented by the construction of high-quality maize genetic genome groups; enhance unified prevention and control and improve the coverage of green control and prevention; and reduce the number of chemical pesticides used alongside other measures, which may effectively enhance the low-carbon productivity of maize by 15.4%.
