[会议论文 ] Rainfall Prediction for Enhancing Crop-Yield based on Machine Learning Techniques 进入全文
IEEE
The agriculture industry is the backbone of the economy in nations like India. Many agricultural crops in India have been impacted by climate change. As a country's population grows, its reliance on agriculture grows, and the country's economic process suffers as a result. In this situation, crop yields have a significant impact on the country's economic progress. There were insufficient food grains to feed the populace. Despite the existence of numerous methodologies or procedures for estimating agricultural production, their accuracy is not up to par. According to the literature review, there are no acceptable remedies or technologies to address the aforementioned condition. This method represented a push toward over-mechanization of agriculture. Agriculturists were encouraged and supported to engage in technology-based farming. This initiative attempts to assist farmers in forecasting future harvests and properly managing their costs by taking into account variables such as temperature, rainfall, and land acreage. To forecast the crop output of a certain agriculture region depending on the quantity of rainfall, the proposed method employs machine learning techniques and multilayer Perceptron. Farmers will be able to anticipate crop yields prior to planting and make the appropriate investment decisions as a result of this research. To estimate agricultural yields early in the harvest, this approach also focuses on appropriate marketing and storage stages. The findings of the suggested system are made available to the farmer group. The suggested technique is beneficial for precisely anticipating agricultural yield output.
[学术文献 ] 紫色土埂坎典型草本根系摩阻特性对土壤含水率的响应 进入全文
草业学报
为进一步探索紫色土埂坎草本根-土界面摩阻特性与土壤含水率的关系，以紫色土埂坎常见稗草、马唐和牛筋草3种草本根系为研究对象，设置不同土壤含水率（5%、10%、15%、20%和25%），通过直剪和拉拔摩阻试验测定草本根-土复合体的摩阻特性指标（黏聚力、摩擦系数、最大抗拔力和抗拔强度），分析了土壤含水率对不同草本根-土界面摩阻特性的影响。结果表明：1)当含水率为15%和20%时，根-土界面黏聚力达到较小值，而摩擦系数、最大抗拔力和抗拔强度达到较大值。2)3种草本根-土界面拉拔摩阻特性差异显著（P＆lt;0.01），牛筋草根-土界面平均最大抗拔力和抗拔强度分别是马唐的1.18和1.30倍，是稗草的1.14和1.10倍。3)草本根-土界面间抗剪强度和垂直荷载的关系服从莫尔-库伦准则。当含水率为20%和25%时，根-土界面间抗拔力达到较大值。4)在相同垂直荷载和土壤含水率条件下，牛筋草根-土界面抗剪强度显著高于马唐和稗草（P＆lt;0.05）。由此可知，牛筋草根系能增强紫色土埂坎稳定性，其根系对埂坎的加固作用约在土壤含水率为15%时效果最佳。研究结果可为三峡库区紫色土埂坎固埂护坡草本植物的筛选提供参考。
[前沿资讯 ] 新疆麦盖提县：打造“节水丰产”新样板 进入全文
农民日报
今年以来，新疆麦盖提县积极落实“藏粮于技，藏粮于地”战略，立足高标准农田，小面积试验种植小麦浅埋滴灌宽幅匀播技术，充分发掘农田节水潜力，增强农民节水意识，助力农业节水转型升级。当前，小麦生长已进入后期管理阶段，田间去杂工作是保障种源纯度的一项关键措施。在麦盖提县希依提墩乡东风村滴灌小麦试验田里，村民巩建林正在和技术人员一起给小麦除杂。放眼望去，田地里的小麦茎秆粗壮、麦穗硕大、籽粒渐丰，微风过处麦浪滚滚，滴灌小麦的种植方式让巩建林赞不绝口。“今年我家的192亩小麦都运用的是小麦浅埋滴灌宽幅匀播技术，预计今年每亩小麦产量能达到520公斤，对比往年每亩产量要高100公斤。”巩建林介绍。据介绍，麦盖提县滴灌小麦种植新模式一改过去大水漫灌的传统灌溉方式，采用浅埋滴灌水肥一体化新技术进行精量滴灌。巩建林家的小麦种植运用上滴灌设施后，实现了冬小麦浇灌从大水漫灌到精量滴灌的转变，获得了比常规灌溉方式节水65％左右的良好效果。不仅如此，省工、省时、省力，成本还低，这些优点让巩建林一开始试验种植的担心全无，直呼划算。这种新技术还可达到节肥24％、节本增效17％的成效，从而助推种植户实现节本增效、增收节支，让群众日子过得更殷实、更红火。
[学术文献 ] 黄土高原不同降水量区苹果园土壤干燥化效应及生产水足迹模拟 进入全文
应用生态学报
为探明黄土高原地区旱作苹果园深层土壤干燥化效应和生产水足迹动态变化，选择半湿润区洛川和半干旱区米脂两个典型苹果种植区，采用WinEPIC模型定量模拟分析两个区域1980—2020年旱作苹果园0～15 m土壤水分动态变化和苹果生产水足迹演变规律。结果表明：洛川和米脂成龄果园年产量大致呈“S”型趋势变化，年均值分别为24.64和18.42 t·hm-2；年均蒸散量分别为623.82和458.97 mm，年均干旱胁迫日数分别为20.40和52.73 d，年均水分过耗量分别为167.94和121.15 mm。洛川1～25龄、米脂1～23龄果树土壤有效含水量下降趋势明显，土壤干燥化速率分别为64.60和68.03 mm·a-1；洛川和米脂深层土壤干层形成的时间为第13年和第7年，并分别于第23年和第22年后达到稳定，降水量高的地区形成和达到稳定土壤干层的时间较晚，如果土壤水分长期处于亏缺状态，最终会形成不可逆转的土壤干层。洛川和米脂苹果生产水足迹均呈前期低后期高的特征，年均生产水足迹值分别为0.187和0.194 m3·kg-1。苹果产量和生产水足迹受降水影响，在水资源短缺的黄土高原地区，为了苹果产业能够持续健康发展，建议苹果树最佳种植年限为23年左右，最多不应超过25年。
[会议论文 ] Development of Racking and Irrigation System for Industrial Revolution 4.0 Vertical Farming 进入全文
IEEE
This paper presents a design for multi-layer vertical farming rack to be used as an integrated component in fully automated farming of ginger plants with minimum interactions of humans, in line with Industrial revolution 4.0. The vertical rack is designed in parallel so an Automated Guided Vehicle (AGV) can travel along in the middle for data collecting, observation and retrieving purposes. The whole rack system can hold 96 plants, consists of two 19 m rows. Each row has two stacks of plants. 64 units of plants will receive LED treatment, where else the balance 32 unit of plants will not have LED installed for experiment purposes. Rack will be equipped with protrusions to assist robot with its position sensor. Also, each plant containment will be equipped with required LED lights and watering system, complete with waste water drainage path. AGV was tested along the racks to test its stability and reachability of the arm in retrieving plants tray. This test was carried out using dummy load to test the overall strength, vibration and accuracy of the AGV arm. All tests passed satisfactory.
[会议论文 ] Novel Robotic Approach to Irrigation and Agricultural Land Use Efficiency 进入全文
IEEE
Current industrial agricultural methods often use inefficient watering, fertilizing, and pest control practices, in part because they lack feedback systems. The prototype proposed combines current agricultural sensing and analysis research with a robotic platform to precisely monitor and care for crops. In this paper, we provide a proof of concept with a path to scalability such that the system may be implemented at an industrial scale.
