Abstract Objective: The modernization of irrigation areas is an important guarantee of national food security. Make clear the health status of irrigation projects, put forward the renovation plan for modern irrigation areas, guide the construction of modern irrigation areas, and promote agricultural modernization. Method: Taking Lailong Irrigation District in Jiangsu Province as an example, the health evaluation index system of key projects in the irrigation district was constructed, and the weight of each evaluation index was calculated by AHP and a fuzzy comprehensive evaluation model (AHP-FCE) to evaluate the health status of key projects. Results: The proportions of “good”, “medium” and “poor” in the comprehensive evaluation of the health status of the pump station project and the sluice project in Lailong Irrigation District were 16.72%, 53.33%, 30%, 13.51%, 48.65%, and 37.84%, respectively. In the evaluation of the criterion level, the proportion of “poor” information level evaluation level reached 63.33% and 64.86%. This paper analyzes the key problems and weak links of the modernization of the irrigation project in the Lailong irrigation area and puts forward the requirements for the modernization of the Lailong irrigation area according to the basic characteristics of the modern irrigation area. Conclusion: Water-saving reconstruction projects in irrigated areas basically meet the requirements of irrigation and drainage, but information technology has not been applied in the reconstruction of irrigated areas, and the construction of modern irrigated areas should pay more attention to information construction. This paper provides a theoretical basis and technical support for the modernization of irrigation areas in Jiangsu Province.

Abstract The movement track of agricultural machinery includes not only the field operation track but also the road driving track. Effectively distinguish the operation tracks of field operation and road driving during the driving of agricultural machinery, accurately divide effective operation plots, and accurately evaluate the operation efficiency of agricultural machinery so as to realize remote intelligent management of agricultural machinery. Typical characteristic data was extracted by analyzing attributes of agricultural machinery trajectory points, and a training model established by the method of BP_AdaBoost was used to recognize track points of agricultural machinery. After remarking error-prone track points at the junction of road and field, it was trained again. The correct rate of track recognition was 96.89%. It not only avoided the dependence of traditional clustering algorithms on thresholds and parameters but also effectively solved the problem of mistaking road driving trajectory into field operation trajectory.

Abstract Society still faces serious environmental and socioeconomic problems, which have only been partially offset by the rapid development of knowledge, information technology, and technology; however, sustainable development remains a goal. This article aims to establish a debate on the contribution of agriculture to sustainable development and to analyze the role of the university in this process. Different alternatives to agricultural production that can contribute to sustainability are critically reviewed. These include good agricultural practices that seek to preserve the environment, including agroecology and organic agriculture, precision agriculture, and some applications of biotechnology. There is currently a need to establish evaluation methods that allow objective identification of progress or setbacks in the quest for sustainability. In the implementation of the concept of sustainable agriculture, universities have an essential role to play as the main source of scientific truth and center of knowledge, without detracting from the legitimacy and value of other epistemic systems such as peasant, traditional, or local knowledge.

Abstract A prolonged release system (SLIP) of urea powder encapsulated in a wheat gluten matrix was investigated as a sustainable substitute for use in agriculture with the goal of lowering nitrogen losses in the soil. Thermogravimetry (TGA), Fourier Transform Infrared Spectroscopy (FT-IR), and Scanning Electron Microscopy (SEM) were the methods used to characterize SLIP. The urea release kinetics in water were then assessed. Very porous structures were produced, the thermal stability of SLIP was noted, and interactions between urea and gluten proteins through hydrogen bonds were verified. According to the kinetics, urea was released at a high rate (38%) in the first ten minutes and reached the diffusion equilibrium (86.35%) after 36 hours. There is a chance that urea SLIP will be employed as a sustainable substitute in agriculture.

Abstract To explore the light intensity suitable for the growth of purple leaf lettuce seedlings in plant factories and greenhouses, the effects of light intensity of 6000, 12,000, 18,000, 24,000, and 30,000 lx on growth morphology, nutritional quality, photosynthetic pigment, and photosynthetic characteristics of purple leaf lettuce seedlings were studied with ‘Beizisheng 3’ as the experimental material under the condition of white light quality unchanged. The results showed that under a light intensity of 30,000 lx, purple leaf lettuce seedlings grew well, and the biomass, chlorophyll a content, chlorophyll b content, carotenoid content, total chlorophyll, soluble protein content, soluble sugar content, vitamin C content, anthocyanin content, net photosynthetic rate, transpiration rate, and stomatal conductance were the largest, while the nitrate content and intercellular CO 2 concentration were the lowest. However, chlorophyll b content, carotenoid content, soluble protein content, and transpiration rate had no significant difference compared with those under 24000 lx light intensity, and the plant height was the highest under 24,000 lx light intensity. Under the condition of white light quality, the most suitable light intensity for the growth of purple leaf lettuce seedlings is 30,000 lx.

Abstract Avocado is a traditional fruit in the diet of Ecuadorians and requires proper crop handling to guarantee high production. Implementations of new technological alternatives, such as spectroscopy indexes that correlate with each other, will optimize avocado crop management. This research validated the use of red band and near infrared-based plant indices with leaf nitrogen content. The plant indices used were normalized differential vegetation index (NDVI) and transformed vegetation index (TVI). These indexes were developed from two orthomosaics, obtaining images that capture red and near-infrared bands. Regression and correlation analysis were performed between the vegetable indices and the foliar nitrogen content analysis, generating R 2 values of 0.93 for NDVI, and 0.95 for TVI. The values of the plant indexes can be used to estimate plant vigor based on the nitrogen content of the foliar area.
