In order to understand the effects of sugarcane-peanut intercropping on the peanut and sugarcane， field experiments of sugarcane monoculture，peanut monoculture and sugarcane-peanut intercropping were carried out. The results showed that， when compared with sugarcane monoculture，the sugarcane plant height increased by 5.22%，the single effective stem weight increased by 10.53%， the stem length increased by 15.39%， the effective stem number increased by 0.05%，the sucrose content increased by 6.18%，and the yield increased by 9 997 kg/hm2 in the sugarcane-peanut intercropping field. When compared with monoculture peanut，intercropping peanut grew well and the yield was relatively stable. Soil pH decreased and soil conductivity increased in the intercropping field. In conclusion，peanut-sugarcane intercropping can improve the agronomic and economic properties of sugarcane，and significantly improve soil pH and electrical conductivity. Therefore，sugarcane-peanut intercropping is an efficient cultivation mode.

The presence of organic dyes in water causes significant ecological and public health problems，thus remediation of water contaminated with organic dyes is of great importance. In this paper，aminated magnetically reduced graphene oxide （NH2-MrGO） was synthesised by co-precipitation method and used for the adsorption of methyl orange （MO） in water. The synthesized composites were characterized by advanced techniques，including scanning electron microscopy （SEM），Zeta potential， fourier transform infrared spectroscopy （FT-IR），and hysteresis return line analysis. Subsequently，the temperature and pH on the adsorption properties were investigated. The findings of the study indicated that the maximum adsorption of MO by NH2-MrGO was 15.7 mg/g，with a removal rate of 78.5%. Meanwhile，the adsorption process was found to be consistent with the Freundlich model. This study can provide theoretical support and data reference for the treatment and elimination of organic dye pollutants in water.

To determine the best extraction process of liquiritin from licorice，single factor experiment and orthogonal experiment were designed，and the antioxidant activity of liquiritin was preliminarily studied. Ultrasound-assisted extraction was used as the extraction method，and the yield of liquiritin was used as the evaluation index. The effects of extraction temperature，extraction time，solid-liquid ratio， ultrasonic power，and ethanol concentration on the extraction yield were investigated. On the basis of single factor experiment，the extraction process of liquiritin was optimized by orthogonal design. The antioxidant capacity of liquiritin was determined by DPPH free radical scavenging assay and hydroxyl free radical scavenging assay. The results showed that the optimal extraction condition was obtained at 50% ethanol concentration，solid-liquid ratio 1：10（g/ mL），45 ℃，35 min，and ultrasonic power 350 W. Under these conditions，the extraction yield was 3.46 %. The antioxidant activity study showed that the scavenging rate of liquiritin on DPPH radical and hydroxyl radical was 70.99 % and 20.07 %， respectively. The ultrasound-assisted extraction method can be used for the extraction of liquiritin，and the licorice extract had good antioxidant activity.

Aiming at the problems of high misidentification rate and low efficiency of manual identification in the actual environment of mushroom production and sales，21 types of common edible mushroom images of nationals using different devices and ways were collected and a dataset was established．A mushroom detection and classification model MR-YOLO was proposed on the improvement of YOLOv5s，which improves the performance of the algorithm model under the circumstance of maintaining the depth and width of the network unchanged．The network structure of the native YOLOv5s algorithm was modified，and the convolutional block attention module（CBAM） attention mechanism was introduced to ensure that the model can improve the recognition precision and accuracy while saving parameters and computation．In addition，spatial pyramid pooling cross stage paritial connection （SPPCSPC） was used in the model pooling layer to enable the model to obtain different sensory fields during the feature extraction operation，which can effectively solve the negative impacts brought by the significant differences in the size of the image targets．The C2f module was used in the model convolution layer to ensure that the model can obtain a richer information flow while being lightweight． Experimental results show that MR-YOLO improves the recognition accuracy by 4. 1% compared with the official native YOLOv5s．And the edge loss，classification loss，and confidence loss are reduced by 8.0%，16.4%，and 9.7%，respectively．It proves that the MR-yolo model has stronger performance compared with YOLOv5s.

Green development is an inevitable requirement for implementing the new development concept and constructing a new development pattern．However agricultural non-point source pollution seriously hinders the comprehensive green transformation of agriculture．To promote the sustainable development of agricultural economy in Anqing City，data on four indicators of per capita agricultural output value and agricultural non-point source pollution in Anqing City from 2001 to 2022 were selected． Based on the Environmental Kuznets Curve （EKC）theory，an optimal model was established by fitting linear，quadratic，and cubic function models to analyze the relationship between agricultural economic growth and agricultural non-point source pollution in Anqing City．The empirical results show that there are significant inverted “U”-shaped，“N”-shaped，and inverted “N” - shaped curve relationships between fertilizer application，agricultural diesel application，pesticide application，agricultural film application，and per capita agricultural output value，respectively． The inflection points have all arrived in the research time series．Based on this，suggestions are proposed to improve the institutional system，increase investment subsidies，establish green concepts，scientifically and accurately govern， and develop ecological agriculture，in order to promote high-quality economic development and high-level ecological protection in Anqing City．

Based on the investigation of 160 different under-forestry economic management entities in Guangdong Province，the economic production efficiency of different production types and different management agents were measured by using the CCR method of DEA model，and the Tobit model was constructed to analyze the influencing factors of the under-forestry economic production efficiency．The results are as follows：（1） From the perspective of the three production types，the technical efficiency and scale efficiency of aquaculture are the highest，followed by planting and breeding，while that of planting are the lowest．（2） From the perspective of the three management entities，the corporate- led farmers show the highest technical efficiency and scale efficiency，and the highest comprehensive efficiency，while the lowest technical efficiency is the single-management farmers，and the cooperatives led farmers have the lowest scale efficiency．（3） Among the factors affecting the economic productivity of the under-forest economy，economic profit，irrigation conditions，education level of the household head， social position of the household head， technical training and joining economic organizations all have positive impacts on the improvement of the economic productivity of the under-forest economy，while age has a negative impact．Therefore，the government needs to provide policy support in technical training， financial subsidies，the cultivation of new business entities，social service institutions，and attracting outstanding farmers to return to their hometowns to engage in green and efficient understory economic production or entrepreneurship.

The significance of pesticides to global food security cannot be overstated，as they serve as an indispensable means of production in agricultural practices. The key to enhancing the utilization rate of pesticides lies in optimizing the affinity between pesticides and leaf surfaces，as well as improving their deposition and adhesion capabilities on the leaf surface. Based on this，the factors influencing the wettability of pesticide droplets on plant leaves were analyzed in this paper，and the impact of pesticide droplet characteristics （including surface tension and contact angle） on their uniform adhesion or localized infiltration on leaves and deposition rate were reviewed. Furthermore，the effects of leaf surface morphology，including microstructure，waxy layer，leaf shape，and surface free energy on its wettability were further discussed. Lastly，a comprehensive investigation was conducted on the application of nanopesticides on the plant leaf surface.
