查询词典 sugarcane

As the track space increasing, the holding power which flexible holding parts act on sugarcane is dropping off. As the canvas layers and length of flexible holding part increasing, the track space is also increased when flexible holding parts act on sugarcane same holding power. As the length of flexible holding part increasing, the rate of slope of holding power following the track space to change would be decreased, so holding power would vary slowly. The holding power has a better linear relationship with the track space. Holding sugarcane stalk on knot or not on knot, sugarcane stalk having leaves or without leaves, the holding power would have not significant difference. Considering the structure of device and stress of sugarcane, 4-layers canvas conveyer belt was used as flexible holding part, while its length is 120mm, 160mm, or 200mm, the corresponding maximum track space is 135mm, 183mm, or 235mm. Experimental investigation of sugarcane windrowing was done on the arc-track-type flexible holding and conveying test mechanism.

随着轨道间距的增大，柔性夹持元件施加给甘蔗的夹持力逐渐减少；施加给甘蔗相同的夹持力，随着柔性夹持元件帆布帘层数和长度的增加，对应的轨道间距增加；随着柔性夹持元件长度的增大，柔性夹持元件施加给甘蔗的夹持力随轨道间距变化的斜率减小，夹持力大小的变化越缓慢；柔性夹持元件提供的夹持力与轨道间距均呈线性关系；柔性夹持元件夹在甘蔗节上还是不夹在节上，甘蔗有叶还是无叶，其施加给甘蔗的夹持力无显著差异；从夹持输送装置结构以及甘蔗的受力情况来考虑，选择4层帆布帘输送带作为柔性夹持元件更能平稳、柔和地夹持输送甘蔗，4层帆布帘120mm、160mm、200mm长的柔性夹持元件夹持甘蔗所需最大轨道间距为135mm 、183mm、235mm。

Positive significant correlation between three infection indexes and SDD, and negative insignificant correlation between infection indexes and LIP were found. Fifteen sugarcane varieties could be divided into 6 groups on the basis of the distance more than 1.0. It resulted most ot tested sugarcane varieties had similar smut resistance. It suggested that smut race 1 and race 2 were included in inocula and the condition for Ustilago scitaminea infection was suitable in the crop season by setting up the standard varieties of NCo310, F134, NCo376 and Ya71-374 for smut identification. In addition, the results of sugarcane varieties resistant to smut race 1 and race2 were known by only a simple field trial.

结果显示：9个引进甘蔗品种中，ROC26属于感病品种，其余属于抗病或高抗品种；3个病情指数和持续发病期的两两相关均为显著正相关，潜伏侵染期与这些参数的相关为负相关，但未达到显著水平；在类间距离大于1.0的条件下，可将15个品种聚为6类，进一步明确了各品种抗黑穗病性的相似程度；抗性鉴定标准对照种NCo310、F134、NCo376和Ya71-374的应用，明确了接种源为小种1和小种2，通过一次接种试验，明确了供试品种对2个小种的抗性水平，标准对照种的抗性表现，还说明了本生长季发病条件基本是适宜的。

Sugarcane mosic virus disease and sugarcane ratoon stuning disease harmful greatly on the yield and quality of sugarcane cultivation are widespread in the world.There is no any specific drug can control these diseases at present.Production and application of disease-free seed canes is an effective solution to control these diseases.

甘蔗花叶病(sugarcane mosic virus disease，SCMV)和宿根矮化病(ratoon stuning disease，RSD)是世界范围内广泛发生的两种病害，对甘蔗产量和品质造成重大影响，当前尚无特效药，生产上采用脱毒的健康种苗是控制这些病害的有效措施。

Sugarcane stem borer and Ceratovacuna lanigera Zehnther are the main pests of sugarcane, which not only make sugarcane yields loss but also make sucrose content decline.

蔗螟和绵蚜是甘蔗的重要害虫，它们不但造成甘蔗产量损失、蔗糖含量的下降，还传播多种甘蔗病毒，传病造成的损失比直接为害造成的损失更为严重。

At the latter stage of sugarcane growth, total N, OM, Cl(superscript -) sugarcane fields are lower than in 75 ton treatment in sugarcane fields. Soil fertility, OM and HA content, and catalase and polyphenol oxidase activity are higher in the four vinasse treatments than in CK1 and CK2 treatments. Sugarcane plantation absorbs vinasse nutrient and purifies soil environment when treated with vinasse.

说明与施用化肥或不施肥处理相比，蔗地施用废液有提高土壤肥力和有机质、腐殖质含量的作用，但也使施用初期过氧化氢酶和多酚氧化酶活性异常升高，施废液的土壤种植甘蔗对废液养分吸收和环境净化有一定作用。

In order to investigate whether fragments of Sugarcane bacilliform virus were integrated into Saccharum inter-specific hybrids genome, a DNA fragment homologous to SCBV was amplified from a hybrid sugarcane plant Saccharum inter-specific hybrids var.

为研究甘蔗杆状病毒Sugarcane bacilliform virus的基因组片段是否整合进杂种甘蔗Saccharum inter-specific hybrids基因组，以采自广西甘蔗研究所的1株杂种甘蔗植株叶片总DNA为模板，根据已报道的甘蔗杆状病毒基因组序列设计多条特异引物。

The effects of enhanced UV-B radiation on plant height and stem diameter of 10 wild sugarcane (Saccharum spontaneum L.) clones for 3 consecutive years under field condition was investigated.

wild Sugarcane； stem diameter ；研究了大田栽培和自然光条件下，连续3年模拟紫外辐射(UV-B，280~315nm)增加对10个割手密无性系伸长期株高和茎径的影响。

Previous studies focused on cutting and lifting sugarcane stalks, the sugarcane stalks holding and conveying research was almost blank. Researching and designing new holding and conveying mechanism, providing the basis for the design of sugarcane harvester, reducing the plugging and breaking of sugarcane stalk, increasing windrowing quality, reducing power consumption, have important theoretical and practical significance.

以前的研究主要集中在甘蔗切割和扶起方面，对于甘蔗夹持输送机理的研究几乎是空白，研究设计新型的夹持输送机构，研究其工作机理，为甘蔗收割机的设计提供依据，减少甘蔗的堵塞和折断，提高铺放质量，降低功耗，具有重要的理论意义和实用意义。

As the forward velocity increasing, the windrowing angle would be decreased, but the effect of forward velocity on windrowing distance was not obvious. The windrowing angle and distance of multiple sugarcane stalks would be smaller than those of single sugarcane stalk, but the maximum range of windrowing angle and distance of multiple sugarcane stalks would be greater than those of single sugarcane stalk. In order to sugarcane stalks outward windrowing, holding height must be within ±100mm of height of sugarcane mass center. As holding height increasing, the windrowing distance would be decreased, but the effect of holding height on windrowing angle was not obvious.

随着夹持输送装置输送速度的增大，甘蔗铺放角和甘蔗铺放距离也随着增大，随着机车前进速度的增大，甘蔗铺放角是减小的，而前进速度对甘蔗的铺放距离影响不大；多根甘蔗的铺放角和铺放距离要比单根甘蔗小，铺放角和铺放距离最大极差要比单根甘蔗大；入口夹持点高度应在甘蔗质心高度±100mm范围内为宜，以保证甘蔗能向机车外侧铺放，随夹持高度的增加，甘蔗质心位于夹持点下方的距离增大，甘蔗铺放距离减小，而夹持高度对甘蔗铺放角影响不大。
