【目的】探明硅在甘蔗植株中的分布特征和筛选硅高效吸收积累的甘蔗基因型。【方法】本研究以23个基因型甘蔗为供试材料，测定成熟期甘蔗各器官中硅的分布与积累特征，并比较不同基因型甘蔗对硅的吸收积累差异。【结果】硅含量在甘蔗各器官间存在显著差异，分布趋势为：叶片>叶鞘>根系>蔗蔸>蔗皮和蔗髓。叶片和叶鞘的硅含量均在甘蔗不同部位间差异显著，以植株中部最高。甘蔗植株各器官的硅积累量分布趋势为：叶片>叶鞘>蔗蔸>蔗髓>蔗皮>根系，硅积累量主要集中于地上部，其中叶片和叶鞘的在植株中占比较大，二者之和达到59.88%～72.42%。硅含量和硅积累量均在不同基因型甘蔗间存在显著差异，在供试甘蔗基因型中‘德蔗07-36’、‘柳城05-136’和‘粤糖50号’表现出对硅更为高效的吸收和累积特征。甘蔗生物量与硅含量间相关性密切，其中地下部植株生物量分别与蔗叶、蔗茎硅含量间显著正相关(R~2=0.63,P<0.01;R~2=0.50,P<0.05)。【结论】硅在甘蔗植株上的分布主要集中于地上部，其中蔗叶(叶片+叶鞘)的硅含量和硅积累量最高。甘蔗植株对硅的吸收积累存在基因型差异，具有较为发达的地下部生物量有助于促进甘蔗对硅的吸收累积。

Abstract ：
Ab s tr a c t. The mechanization of the whole process of sugarcane harvesting is an integral part of reducing the cost of sugarcane production. In order to select sugarcane strains suitable for mechanized harvesting, in this experiment, a dynamic resist-ance strain gauge and other equipment determined the related mechanical property parameters such as density, elastic modu-lus, and Poisson's ratio of different sugarcane varieties. Ansys/ explicit dynamics were used to establish a finite element model of the disc cutting device and to simulate the forces exerted on the stalk during sugarcane harvesting and also the quality of the cut section. Then, after obtaining the regression equation analy-sis and the response surface through the cross-section mass, the field harvesting experiment verifies the simulation results. The results show that the density, elastic modulus, and Poisson's ratio significantly affect the cutting quality within the three types of mechanical parameters. Through response surface analysis, when the elastic modulus is 92 MPa, the density is 1145 kg m-3, the Poisson's ratio is 0.404, the best cutting quality was obtained, and the section flatness is 57.09%. According to the cross-sec-tional regression equation, the calculation results are as follows: Liucheng 05-136 > Yuetang 94-128 > Guitang 42, which is the same as the actual harvest quality results under the two planting modes. This indicated that the difference in the mechanical prop-erties of the sugarcane would significantly affect the quality of mechanical harvesting, which provides a reference direction for selecting sugarcane varieties suitable for mechanized harvesting.

Abstract ：
As an economical, efficient, and time-saving engineering technology, determining the dynamic mechanical properties of biocomposites have been widely used in non-destructive testing technology, such as the measurement of dynamic elastic modulus (E-d) and dynamic Poisson's ratio (& mu;). Here, the experiment measured the values of & mu;(LT).& mu;(LR).& mu;(RT) its dynamic elastic modulus at different positions of five common sugarcane varieties (Regan 1, Liucheng 05-136, Guitang 42, Funong 41, Yuetang 94-128). The results showed that the Poisson's ratio values of & mu;(LT) and & mu;(LR) were the same, but there were significant differences in & mu;(RT). The numerical results between different varieties showed significant differences in dynamic elastic modulus measurement. To further verify the reliability of the data, the experiment measured the static elastic moduli of five sugarcane materials by employing a universal testing machine. The values of the static elastic moduli and the dynamic elastic moduli were the same. The experiment observed significant mechanical differences among sugarcane varieties. In conclusion, our findings provide some basic support for the follow-up mechanical simulation analysis and lodging resistance research of sugarcane stalks.

Abstract ：
Different sugarcane cultivars are grown to produce renewable energy and sugar in China. However, we have a limited awareness of the interactive influence of varying sugarcane cultivars on rhizosphere bacterial structure and diversity. Assessing cultivar choice impact on soil bacterial communities is vital since bacterial taxa are frequently impacted by planting performance. Employing high-throughput Illumina sequencing, we examined bacterial communities' assemblage in the rhizosphere of six Chinese sugarcane cultivars (Regan14-62, Guitang 08-120, Haizhe 22, Guitang 08-1180, Taitang 22 and Liucheng 05-136). Our results indicated that different sugarcane cultivars have no significant influence on the Shannon index; however, their impact on richness was substantial. There was a difference in the bacterial community structure that is also associated with a change in the community composition, as determined by the DESeq2 results, suggesting that "Haizhe 22 (HZ22)" had a completely different beta diversity as compared to other five cultivars by enriching abundance of Firmicutes, Proteobacteria, Gemmatimonadetes, Saccharibacteria and Bacteroidetes and reducing the quantity of Actinobacteria, Chloroflexi, Acidobacteria, and Planctomycetes, respectively. The HZ22 rhizosphere significantly enriched six genera (e.g., Devosia, Mizugakiibacter, Mycobacterium, Nakamurella, Rhizomicrobium, and Virgibacillus) relative to other varieties, suggesting an important role in plant disease tolerance and growth development, including soil nutrient cycling and bioremediation. Analysis of similarity (ANOSIM) and correlation analysis revealed that cultivars, soil organic matter, pH and soil moisture were central factors influencing bacterial composition. These findings may help in selection of plant cultivars capable of supporting highly abundant specific beneficial microbial groups, improving plant disease resistance, growth stimulation, and soil bioremediation capabilities, further leading to improvements in breeding strategies.

Abstract ：
This research established a virtual prototype of the sugarcane cutting system. The influence of the harvester on the cutting time of sugarcane stalks under the conditions of different forward speeds and cutting disc speed was studied. Using a dual variance analysis of the experimental data, it was revealed that the rotating speed and forward speed of the cutter disc of the sugarcane cutter had a significant influence on the cutting time. The empirical regression equations between the cutter spin speed-n of the sugarcane cutting device, the forward speed-v of the harvester, and the cutting time-T are given, that is, T = 12.38 - 0.5875v - 0.0137n. Further analysis of repeated cutting and missing cutting during the cutting process was conducted. The result revealed that the optimized cutting disc speed range value was as follows: 423-579 rpm, and the optimal forward speed range value is as follows: 0.66-3.07 m/s.

Abstract ：
为明确机械收获对蔗地土壤物理性状和宿根蔗产量的影响,以消除蔗农对大型机械收获系统对甘蔗耕层土壤严重压实的顾虑。以广西红壤坡耕地为研究对象,设置机械收获和人工收获2种处理,研究机械收获对耕层土壤物理性状和宿根蔗产量的影响。结果表明:蔗垄0～40 cm土层,土壤容重、贯入阻力、抗剪强度、田间持水量和总孔隙度等土壤物理性状在机械收获和人工收获间均无显著差异。蔗沟0～20 cm土层,机械收获后,土壤紧实度、贯入阻力和抗剪强度显著提高,总孔隙度和通气孔隙度下降。同人工收获相比,机械收获过程中,机具行走对蔗沟土壤造成压实,但对蔗垄土壤影响不显著。蔗垄土壤紧实度在垂直梯度上存在2个明显交替变化的界面,0～20 cm土层以人工收获的土壤紧实度较高,20～40 cm土层以机械收获的土壤紧实度较高。第1年宿根季和第2年宿根季人工收获处理蔗茎产量均高于机械收获处理,但差异不显著。综上所述,在固定道技术下,甘蔗机械收获对蔗垄土壤物理性状和宿根蔗产量的影响不显著。本研究为规范甘蔗机械收获操作,减少大型机械对蔗地土壤压实提供了科学依据。

Abstract ：
BackgroundStraw retention is a substitute for chemical fertilizers, which effectively maintain organic matter and improve microbial communities on agricultural land. The purpose of this study was to provide sufficient information on soil fungal community networks and their functions in response to straw retention. Hence, we used quantitative real-time PCR (qRT-PCR), Illumina MiSeq (ITS rRNA) and FUNGuild to examine ITS rRNA gene populations, soil fungal succession and their functions under control (CK) and sugarcane straw retention (SR) treatments at different soil layers (0-10, 10-20, 20-30, and 30-40cm) in fallow fields.ResultThe result showed that SR significantly enhanced ITS rRNA gene copy number and Shannon index at 0-10cm soil depth. Fungi abundance, OTUs number and ACE index decreased with the increasing soil depth. The ANOSIM analysis revealed that the fungal community of SR significantly differed from that of CK. Similarly, significant difference was also observed between topsoil (0-20cm) and subsoil (20-40cm). Compared with CK, SR decreased the relative abundance of the pathogen, while increased the proportion of saprotroph. Regarding soil depth, pathogen relative abundance in topsoil was lower than that in subsoil. Besides, both sugarcane straw retention and soil depths (topsoil and subsoil) significantly altered the co-occurrence patterns and fungal keystone taxa closely related to straw decomposition. Furthermore, both SR and topsoil had higher average clustering coefficients (aveCC), negative edges and varied modularity.ConclusionsOverall, straw retention improved alpha -diversity, network structure and fungal community, while reduced soil pathogenic microbes across the entire soil profile. Thus, retaining straw to improve fungal composition, community stability and their functions, in addition to reducing soil-borne pathogens, can be an essential agronomic practice in developing a sustainable agricultural system.

Abstract ：
Straw retention, an alternative to artificial fertilization, commonly mitigates soil degradation and positively affects soil fertility. In this study, we investigated the succession of soil bacteria during two sugarcane straw retention treatments (control (CK) and sugarcane straw retention (SR)) and at four depths (0-10, 10-20, 20-30, and 30-40 cm) in fallow soil in a sugarcane cropping system. Using an Illumina MiSeq (16S rRNA) and soil enzyme activity, we explored the SR influence on soil bacterial communities and enzyme activities and its inclusive impact on soil fertility, with an emphasis on topsoil (0-10 cm) and subsoil (10-40 cm). Our results show that SR effectively improved soil fertility indicators (C, N, and P), including enzyme activities (C and N cycling), throughout the soil profile: these soil parameters greatly improved in the topsoil compared to the control. Sugarcane straw retention and soil depth (0-10 cm vs. 10-40 cm) were associated with little variation in bacterial species richness and alpha diversity throughout the soil profile. Subsoil and topsoil bacterial communities differed in composition. Compared to the CK treatment, SR enriched the topsoil with Proteobacteria, Verrucomicrobia, Actinobacteria, Chloroflexi, and Nitrospirae, while the subsoil was depleted in Nitrospirae and Acidobacteria. Similarly, SR enriched the subsoil with Proteobacteria, Verrucomicrobia, Actinobacteria, Chloroflexi, Gemmatimonadetes, and Bacteroidetes, while the topsoil was depleted in Acidobacteria, Gemmatimonadetes, and Planctomycetes compared to the CK. At the genus level, SR enriched the topsoil with Gp1, Gp2, Gp5, Gp7, Gemmatimonas, Kofleria, Sphingomonas, and Gaiella, which decompose lignocellulose and contribute to nutrient cycling. In summary, SR not only improved soil physicochemical properties and enzyme activities but also enriched bacterial taxa involved in lignocellulosic decomposition and nutrient cycling (C and N) throughout the soil profile. However, these effects were stronger in topsoil than in subsoil, suggesting that SR enhanced fertility more in topsoil than in subsoil in fallow land.
