Thinning is an important agronomic process in pear production, thus the detection of pear inflorescence is an important technology for intelligentization of blossom thinning. In this paper, images of buds and flowers were collected under different natural conditions for model training, and the images were augmented by data augmentation methods. Model training was performed based on the YOLOv5s network with coordinate attention mechanism added to the backbone network and compared with the native YOLOv5s, YOLOv3, SSD 300, and Faster-RCNN algorithms. The mAP, F1 score and recall of the algorithm reached 93.32%, 91.10%, and 91.99%. The model size only took up 14.1 MB, and the average detection time was 27 ms, which are suitable for application in actual intelligent blossom thinning equipment.

Mechanical weeding in paddy fields is a green and environmentally friendly way to control weeds, which has the advantages of reducing the amount of pesticides and improving the physical structure of the soil. This paper briefly describes the composition and relevant parameters of the mechanical weeding environment in rice fields. Using Creo 5.0, HyperMesh 2017, and LS-PrePost and LS-DYNA software to jointly simulate the interaction process between inverted V-shaped inter-plant weeding component and the soil in the paddy field, the single-point ALE multi-material unit algorithm is used to couple the soil and water with multiple substances, and realize the material movement between the soil and the water layer. Using the penalty function method, a fluid-solid coupling finite element modelled on the interaction between inter-plant weeding components and soil-water was established. The dynamic behavior of the interactions shows that the coupling stress increases and then decreases periodically, and the teeth of the spring cross the soil with a "bending moon (fish scale)" scratch, which can effectively avoid rice seedlings and reduce the injury rate.

A sunken solar greenhouse is the original type of greenhouse in China, its soil wall thermal storage performance is better and low cost. Higher benefits of stereoscopic planting in sunken solar greenhouses, while repeated use of the substrate can produce pathogens, so high-temperature smothering is used for sterilization in the summer months of June to August. To investigate the mechanism of indoor temperature and humidity variation and fungicidal effect in a sunken solar greenhouse, a single cross-sectional test of temperature and humidity in sunken solar greenhouse during the smothering period was conducted using wireless sensors. The results showed that: The maximum value of indoor temperature at noon was 69.5°C the temperature value of all measurement points was greater than 50°C for 3h, when removing the measurement points at the upper surface of the ground, the relative humidity value of other measurement points was less than 60% for 5h. During the daytime period, when the indoor temperature is greater than 28°C in the interval 7:00-12:00, the initial relative humidity value of each measurement point is located at 70%-85%; when the weighted temperature of each measurement point starts to rise at a rate of 1.1°C/10min, the weighted humidity of each measurement point declining is 1.3%/10min; the determination of the rate of change of indoor temperature and humidity during the daytime and the starting value can provide a basis for indoor plants to take measures to sterilize at high temperature.

In order to analyze the flow field inside the crushing chamber of machine for lentinus edodes stipe crushing and improve performance of the machine based on the results of the flow field analysis, this paper applied the computational fluid dynamics software FLUENT to numerically simulate the flow field inside the crushing chamber of the machine for lentinus edodes stipe crushing. Thus, the flow field characteristics and flow state inside the crushing chamber were intuitively displayed, and the visualization of the flow field in the crushing chamber was realized. Then, the wind speed value obtained by simulation was compared with the value measured by experiment, and the average relative error between them was less than 10%. Finally, according to the simulation results of flow field, the flow field generated by one air inlet and two air inlets was analyzed, and then the blade structure, outlet area parameters, and rotation speed parameters were compared, simulated and optimized.

Because hydroponic plant nutrient is dissolved in the water, water quality management is essential for growing healthy plants. Taking care of the total dissolved solids (TDS) and the pH (water acidity) is essential. The purpose of this research is to create a IoT-based water quality monitoring device. The average TDS after 30 days of automation with an Arduino UNO was 1162.82 ppm, and the gadget kicked on the nutrient pump whenever the TDS fell below 1000 ppm or the EC fell below 2. The mechanism self-adjusts the pH when it falls below 5.5 or rises above 6.5, with a mean of 6.17.

The relevance of the study is due to the need to reduce the energy intensity of the process of cutting sunflower stalks by choosing a rational profile of knives. The research is based on a comparative analysis of experimental values of cutting forces for the proposed and manufactured design of the knife system and known knife systems. The studies have shown that the implementation of the retaining and main knives of the header in the form of a curved spiral of Archimedes allowed to reduce the cutting force. It was also found that the cutting force for the proposed design of the knife system, unlike other studied, practically does not change with the removal of the stem from the axis of rotation of the knives, which does not require an increase in energy costs for the cutting process.

As one of the ancient cultivated crops in China, millet has the characteristics of high nutritional value, drought resistance and barrenness. It also plays an important role in ensuring the supply of food in our country. At present, most of the millet breeding work uses manual extraction of phenotypic information, which is laborintensive and inefficient. Therefore, the development of an automated, efficient and accurate millet phenotype detection method has practical significance for the extraction of the millet genome. In this study, a combination of sparse reconstruction based on Structure from Motion (SfM) and Patch-based Multi-View Stereo (PMVS) was used to select three different varieties of millet. A total of 81 samples of 9 samples in each period were reconstructed to obtain a 3D model of millet. The combination of conditional filtering and statistical filtering is used to remove the noise points generated during the photographing process, and finally the obtained point cloud data is used to measure the agronomic traits of millet such as plant height and leaf area. The results show that the interval angle of 5° is the best reconstruction angle of millet. The coefficient of determination R2 of point cloud measurement results and manual measurement data regression analysis is higher than 0.94, indicating that the method used for 3D reconstruction has high applicability to different millet in different periods and high-throughput measurement of millet by the method in this paper is feasible. This study provides a theoretical basis for a millet phenotypic information measurement device

The main task was to receive a robust transfer function for the capacitive grain moisture measurement system. It was estimated how the new transfer function compensates for the type uncertainty and how close it is to the nominal values of moisture content. Dispersions of adequacy and repeatability of the new transfer function, which describe possible variation in the measured moisture values and the correspondence of the new transfer function with the nominal linear transfer function of a moisture meter respectively, were calculated for five chosen substances. It was proved that the new transfer function has lower sensitivity to grain type and better adequacy to the ideal transfer function than the closest analog.
