摘要：Through analyzing the form, materials, building techniques of vernacular dwellings in Jinzhai County, Anhui Province, this study tries to explore the influence of agricultural eco-environment on the form of folk houses, points out that vernacular dwellings are fully combined with local traditional agricultural environment from site selection, spatial form, architectural style, building materials and detail designs, which unifies the economic and environmental benefits of vernacular dwellings.

摘要：General situations of South China agricultural University were introduced in this study,while planning conditions and ideas were also analyzed,which put forward the correspondingly planning and designing idea.

摘要：Precision planting is one key point of precision agriculture.A doorframe type swing seedling pick-up device for the automatic precise field transplanter was designed and tested in a *** seedling device could automatically extract seedlings from growing trays,transfer them,and release them into the planting unit where they were to be precisely transplanted into the *** consisted of a path manipulator and two *** path manipulator for seedling extraction was constructed with creative design ofⅡ-type mechanism combination in *** consisted of an oscillating guide linkage mechanism and a grooved globoidal cam *** to the planned seedling pick-up trajectory,the design of the path manipulator for seedling extraction was finished with a set of the closed loop vector *** gripper was a pincette-type mechanism using the pick-up pins to penetrate into the root mass for seedling *** consisted of multiple pick-up pins,U-type pull rod,shaft,stop block,compression spring and *** mechanical dimensions of the gripper were determined by the tray size and plant characteristic with a set of rectangular equations and the boundary constraint *** final gripper was developed on the basis of cultural practice for vegetable seedling in China.A prototype of the seedling pick-up device was constructed to examine whether its working efficacy was satisfactory or *** to the analysis on the work process,the seedling pick-up device could precisely complete a work cycle of approaching,penetrating,extracting,transferring,erecting and discharging a *** pepper seedlings,tomato seedlings and cucumber seedlings as the transplanting objects,the performance tests were conducted to evaluate the practicality and adaptability of the pick-up *** laboratory evaluation showed that the pick-up device equipped with two grippers could extract 70 seedlings per minute with an average success ratio of 90.49%.T

摘要：Dual-roof solar greenhouse, a new style of solar greenhouse, was designed in this study intending to reduce heat loss in cold time and improve land use efficiency in Beijing, the Capital city of China. Designing and applying the dual-roof greenhouse in metropolitan area had dual effects of saving energy and enhancing land use efficiency. According to the monitoring study and analysis conducted in winter of 2012, the averaged night temperature of south room was about 12.1°C in December, which was satisfying for growing average leaf vegetables. Total energy saved by dual-roof in whole winter was quantified as 1.1 × 107 MJ&#46yr-1 (winter), potentially about 37.4 t coal was saved in Beijing area during whole winter-growing period. Considering the application of north room, the land use efficiency was improved by 62.5% in dual-roof solar greenhouse.

摘要：Fishing garden is a particular kind of agricultural gardens. This paper takes the planning and design of fishing garden in Yanglei Township, Wen County, Henan Province as an example to discuss key points in the planning and design of agricultural eco-gardens which are based on the development of fishery for recreation, supported by agricultural picking, consider about its function of both production and sightseeing, highlight "water" landscapes. This garden has relatively rich soil, abundant water resources and good geothermal resources. With the flowing direction of water system as the main line, functional areas were designed along banks and, by combining with forms of the water system and changes of the landform, to form fishing garden landscapes with integration of motion and stillness. The whole garden is divided into 10 functional zones including central service area, water entertainment area, fishing area, lotus viewing area, reed eco-viewing area, barbecue area, camping area, natural leisure area, island sightseeing area and picking area, which can fulfill all leisure demands of tourists. Fishing garden is not common during the construction of new countryside in China, but it has the advantages of less investment, diversified benefits and beautifying the countryside, so it is suitable to be built in the countryside with abundant water resources to develop short-line tourism projects.

摘要："参加完海南的创意农业大会,在去往广州的海航航班上偶遇《云端·新华航空》,碰巧这一期杂志有关于我们"小毛驴市民农园"的报道。我们这些常年脚踏泥土的人显然某种程度上具有浪漫主义情怀,这一期《云端》中关于上山下乡的报道让我们重新回忆那段历史,也让我们再次审视我们"回归乡土"的自我认知。我父母是下乡知青,也结合于那段插队的时光,而我也再次遵循着父母的足迹,先是"洋插队"、现在又"土插队"。总之,觉得自己这辈子难以再离开土地。

摘要：This paper firstly introduced the PHP + Oracle database development technology. Based on B / S structure,using MVC( Model View Controller) framework development mode,and in line with actual demands of fresh agricultural products for e-marketing in Shanghai,it designed and expected to realize e-marketing system for fresh agricultural products in B2B2 C mode. It made an in-depth analysis from system demands,design of functional modules,design of database,and relevant technologies for system realization.

摘要：This paper introduces the approach types of agricultural technology promotion we can choose in the process of new countryside construction, and there are mainly 6 types, namely government-domination-oriented approach, market-development-oriented approach, university (scientific research institution)-education-oriented approach, farmers' participation-oriented approach, direct-training-oriented approach and individual-service-oriented approach, including 20 models. The problems existing in the grass-root agricultural technology promotion in the process of new village construction are analyzed as follows: the awareness of innovation is not strong; scientific research, education, and promotion are disjointed; the construction of specific work system lags behind; the structure of promotion team is irrational, and the quality of promotion personnel is yet to be promoted; the cultural quality of farmers is low, and the cooperative organizations are not sound; the working conditions are poor, and the basic security is inadequate; the investment channel is simple and the supply amount is badly short; the methods of agricultural technology promotion do not adapt to the requirements of new situation. According to the characteristics and internal requirements of grass-root agricultural technology promotion, we creatively design an overall working model, and put forward new measures from objective of grass-root agricultural technology promotion, service object, service content, organization work and scope, method, role of agricultural technology personnel and so on.
