To address these issues, this paper proposed four strategies to promote the deep integration and sustainable development of the low-altitude economy and rural tourism in Henan Province.

Accurately identifying the stage boundaries and characteristic attributes of agricultural mechanization development is a logical prerequisite for following objective laws and promoting the high-quality development of the industry. This paper took the phased laws of social and economic form evolution as the theoretical foundation of Marxist historical materialism, combined the discussion on the particularity of phased contradictions in On Contradiction, and based on the division standards of agricultural mechanization development stages established in NY/T 1408.1—2007 Evaluation of Agricultural Mechanization Level-Part 1: Crop Cultivation it conducted a systematic stage division and characteristic decomposition of China's 77-year development process of agricultural mechanization from 1949 to 2025, from the two dimensions of production mode transformation and employment structure transformation. The research findings indicated that China's agricultural mechanization had successively gone through the primary stage (from 1949 to 2006), characterized by a focus on the modularization, and the intermediate stage (from 2007 to 2025), characterized by a focus on the full-processization. Currently, it was in a critical transitional period as it was moving towards the advanced stage. The primary stage presented the basic attributes of traditional production methods dominating, partial penetration of mechanization, and a relatively low development rate. The employment structure experienced a historical turning point from "increasing machines and increasing people" to "increasing machines and reducing people". The intermediate stage, driven by institutional supply and policy dividends, achieved a historic leap in the full-process mechanization of major crop production. Mechanized production methods established a dominant position, and the total power of agricultural machinery, the comprehensive production capacity of grain, and agricultural labor productivity all achieved a quantitative leap. The social employment structure completed a fundamental reconfiguration from "one, three, two" to "three, two, one". The advanced stage would be characterized by comprehensive, intelligent, and green as its core indicators, pointing to the coverage of agricultural mechanization in all fields and all links and the empowerment of new quality productive forces in industrial upgrading. This paper verified the scientificity and applicability of the division criteria for the stages of agricultural mechanization, clarifies the historical position that China's agricultural mechanization was about to enter the advanced stage, and could provide theoretical support and decision-making basis for the high-quality development of agricultural machinery equipment in the "15th Five-Year Plan" period and the selection of the path for building an agricultural power.

The typical maize-growing area in Tancheng was selected as the experimental area, and traditional round rollers, multi-angled rollers, and rigid-flexible coupled rollers were selected for field comparative experiments. The results showed that the rigid-flexible coupled roller performed better in reducing the grain breakage rate, drop rate, and improving the fruit ear integrity rate, and had certain advantages in energy consumption control and operation efficiency. The results of orthogonal experiments and variance analysis indicated that the roller speed and roller gap had significant effects on the loss reduction effect, with the optimal combination being a roller speed of 950 r/min and a roller gap of 30 mm. The mechanism analysis showed that the flexible buffer layer could effectively disperse the impact force, improve the force state of the fruit ear, and thereby reduce the risk of grain damage. This study provided theoretical basis and practical reference for the structural optimization and parameter matching of the ear-threshing device of maize harvesters.

To enhance the energy-saving level of tobacco drying, an in-depth comparative study was conducted on the application effects of open-type, closed-type, and semi-open-type air-source heat pumped in tobacco drying. Through theoretical calculations and field tests, it was found that the semi-open-type unit, relying on the synergy of heat recovery from waste heat and dynamic moisture removal, had the lowest power consumption for drying dry tobacco leaves, demonstrating significant energy-saving advantages. The research results could provide a basis for the selection and promotion of tobacco drying heat pump equipment.

This paper took Baisha Town of Jiangjin District in Chongqing City as an example, systematically reviewed and standardized the key technologies of the soybean-maize strip intercropping method. It focused on aspects such as variety selection, seed treatment, sowing time, strip configuration, land preparation and sowing, field management, and green control of diseases, pests, and weeds. This provided a reference for the promotion and application of this technology in Jiangjin District and surrounding areas, and aimed to achieve the production goal of stable maize yield and increased soybean production.

Took the Nanyang section of the South-to-North Water Diversion Project as an example, by analyzing the regional and engineering characteristics, types of ecological risks, and governance practices, the key links of collaborative governance were analyzed. A mechanism construction idea was proposed based on the premise of responsibility division, support of information sharing, handling of monitoring and early warning and emergency linkage as the main focus, guarantee of coordinated law enforcement and daily supervision as the support, and support of funds, personnel, and assessment and evaluation as the basis. Further optimization paths were proposed in aspects such as source reduction and ecological restoration of small watersheds, ecological compensation and behavioral incentives, resilience management during sensitive periods, social co-governance and improvement of grassroots capabilities, and full life-cycle management of projects, to promote the collaborative governance of major engineering water source areas under the constraint of high-standard water supply.

Currently, the digital transformation of the entire agricultural industry chain faces common obstacles such as the structural imbalance and functional mismatch of digital infrastructure, the obstruction of the circulation of data elements and the dilemma of value release, the systematic lack of comprehensive digital talents, and the imperfect institutional guarantee and market incentive systems. To this end, it is necessary to form a sustainable development ecosystem by improving multi-party collaborative promotion mechanisms such as infrastructure co-construction and sharing mechanisms, data element circulation and governance mechanisms, talent training and collaborative innovation mechanisms, policy and institutional guarantees, and market incentive mechanisms, so as to break through the bottleneck of digital transformation of the entire agricultural industry chain, truly release the enabling effect of digital technology on the entire agricultural chain, and inject strong impetus into agricultural and rural modernization.

An investigation was conducted on the wild resources in six provinces (autonomous regions and municipalities) from July to September in 2025. Combined with GPS positioning sampling, a total of 55 samples were identified, and an evaluation system consisting of 7 indicators including appearance and nutrition was constructed. The comprehensive score was determined using the analytic hierarchy process. The results showed that Sichuan was the core distribution area, with an altitude range of 800~1 500 meters being the most suitable growth zone; there was a significant regional difference in the total free amino acid content, a total of 4 excellent varieties were screened out, which were suitable for fresh consumption, nutritional health care and processing purposes. The research results could provide scientific basis for the protection and industrial development of Ficus tikoua germplasm resources.
