Abstract:

The purpose of this study is to evaluate the comprehensive benefits of simplified cultivated varieties and their supporting technologies of ‘Gonggu’ series millet, explore the efficient production technology of millet, and promote the high-quality development of millet industry. Based on the survey data of 102 farmers in Northeast China for three years, this study used the osculating value model to evaluate the comprehensive benefits of ‘Gonggu’ series simplified cultivars and supporting production technologies. The results showed that the osculating values of ‘Gonggu’ series varieties in 2021, 2022 and 2023 were 0.0167, 0.1146 and 0.1674, respectively, which were lower than those of common foxtail millet varieties and maize, indicating that the comprehensive benefits of this series of varieties were the highest. On the whole, the osculating value of ‘Gonggu’ series in 2022 was the lowest, which was 0.1350, indicating that the comprehensive benefit of ‘Gonggu’ series in 2022 was the best, while the osculating value of corn in 2021 was the highest, which was 0.6175, indicating that the comprehensive benefit of corn in 2021 was the lowest. The comprehensive benefit of the simplified cultivated variety ‘Gonggu’ series is the best; common millet varieties are in the middle level; corn plays an important role in ensuring grain yield, but the comprehensive benefit is relatively low. Therefore, we should increase the promotion of ‘Gonggu’ series varieties, improve the benefits of common millet varieties, and adjust the industrial structure and technological innovation of maize, so as to improve the comprehensive benefits of various varieties and promote the efficient, environmental protection and sustainable development of agriculture. The method innovation of this study lies in the application of osculating value model, which provides a scientific and objective evaluation tool for the comprehensive benefit evaluation of simplified cultivated varieties of millet, and the conclusion of the results provides a clear optimization direction and strategic suggestions for millet planting.
