Due to the complexity and diversity of agricultural environments, deep learning models based on three-dimensional data suffer from low accuracy and slow efficiency in practical applications, this paper proposes a three-dimensional image recognition method for soybean canopy based on an improved multi-view network. A lightweight network Res2net was used to reconstruct the feature extraction skeleton network in the MVCNN model, and the group convolution module of the network was optimized by embedding the ECA attention mechanism to propose a new three-dimensional image recognition model based on multi-view network (ECA-MVRes2net). In the study, drought soybeans were used as an example to obtain projected images of soybean canopy in six viewpoints using three-dimensional rotation and image feature theory, and the proposed ECA-MVRes2net was applied to carry out three-dimensional image recognition experiments of drought soybeans, and its recognition accuracy, F1 value and Kappa coefficient reached 96.665 %, 96.7 % and 0.924, respectively, compared with MVCNN, MVResnet, Pointnet++ and PointConv models with 3 evaluation metrics average improved by 17.289 %, 17.43 % and 0.356, respectively. The result realized a lightweight fast and accurate network model suitable for three-dimensional image recognition, which provides a theoretical foundation and technical support for the rapid recognition and accurate management of crops based on three-dimensional image processing.</p></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142128666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The photocatalytic evaluation studies were carried out under a very low UVC light intensity (9 W) against acetaminophen (ACE) in the aqueous solution.

The improved efficiency under UVC irradiation was associated with the excellent separation capability of photoexcited charge carriers, ease of electron migration, and electrons’ mediators by the MCC in the composite photocatalyst, as demonstrated by the band gap and photoluminescence analyses.

Decomposition occurred via steam explosion characterized by two key parameters: (1) severity factor (logR0), which combines reaction time and temperature, ranging from 3.25 to 3.75, and (2) pressure, set at 16 and 30 bar. Ultra-high-performance liquid chromatography and gas chromatography were used to analyze sugars, as well as phenolics, furan derivatives, and acids. The highest simple sugar yield (59.2 g/kg biomass) was detected in reed liquid fraction, significantly exceeding corn stalks and wheat straw (21.3 g/kg biomass each). Subsequent acid hydrolysis enhanced the simple sugar content of reed liquid fraction up to 150.4 g/kg biomass, up to 64.5 g/kg biomass for corn stalks and up to 88.3 g/kg biomass wheat straw. These findings show the promising potential of bio-based insulation by-products generated by steam explosion.

The resulted creamed latex, where most rubber particles are covered with creaming agent molecules, was hypothesized to enable coagulation using dilute acid rather than the concentrated acid typically employed in the latex industry. This approach may also resolve the problem of uncoagulated long-storage skim latex, which results from anion formation. Creaming agents were firstly prepared at optimal concentrations of 2.0 wt% (HEC) and 3.0 wt% (TKP), and their molecular characteristics were analyzed using infrared spectroscopy. Various loadings of creaming agents (1.0–14 wt%) were then thoroughly mixed with skim latexes and conditioned at room temperature for 1–4 days to achieve complete separation. The resulting creamed latex was coagulated using 10 wt% concentrated sulfuric acid after the serum layer was separated out. Different properties of the dry skim rubber were characterized through various tests, including Mooney viscosity, plasticity retention index (PRI), dirt content, ash content, nitrogen content, and curing and mechanical properties. It was observed that the optimal concentrations of the creaming agents for preparing creamed concentrate skim lattices were determined to be 7.0 wt% with TKP and 12.0 % with HEC. In addition, only about half or one-third of the dilute acid quantity was required to coagulate the skim creamed HEC and TKP latexes compared with untreated skim latex. Furthermore, skim rubber derived from HEC and TKP creaming agents exhibited typical characteristics within the range of qualities of industrial skim rubbers available in the local rubber market, including Mooney viscosity (in the range 61–82), original plasticity (Po), PRI, curing, and mechanical properties (tensile strength, elongation at break and hardness).</p></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":null,"pages":null},"PeriodicalIF":5.6,"publicationDate":"2024-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142130790","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A three-year experiment was conducted with reduced N (299 kg hm⁻², N3), four proportions of P fertilizer (25:75 % at squaring and bloom-bolling stages (P1), 50 %:50 % (P2), 75 %:25 % (P3), 100 %:0 % (P4)), and a traditional N application (402.5 kg hm⁻², N2) with P2 as control. Under the N3 treatment, the seed yield of P2 was 6.7–24.5 % higher than other P, and the yield of N3P2 was 1.6–2.6 % lower than N2P2. During the whole growth period, P2 demonstrated 12.4–46.9 % higher leaf and reproductive organs dry matter (LDM and RoDM) compared to other P, and primarily due to more mid-upper DM. Throughout the growth period, N3P2 maintained dominant LDM and exhibited RoDM 2.5 % higher at late-full bolling stage (LFB) compared to N2P2. Trends in leaf N content and reproductive organ N content were similar to DM, with N3P2 consistently maintaining higher levels. Regarding N metabolism activities, N3P2 displayed 8.5–16.1 % higher activity of nitrate reductase, 9.5–21.9 % higher activity of glutamine synthetase, and 7.5 %-15.6 % higher activity of glutamate synthase compared to other P across all growth stages, with no significant differences observed with N2P2.
