葡萄裂果病综合防治试验

为有效防治葡萄裂果病，以乍娜和巨峰为材料，进行了综合防治试验，结果表明，采用控制负载量，调整浇灌次数，土施多效唑、适时喷洒多年农化学药剂等以生态调控为主的综合技术，可以使葡萄裂果率降至１０－１２％以下，裂果后的腐烂率降至７￣８％以下，有效地控制了葡萄裂果病的发生和危害。     

Cross-Sectoral Policy Linkages and Environmental Accounting in Forestry

Abstract

It is important to analyze cross-sectoral policy linkages and to quantify their effects by using the system of integrated environmental and economic accounting in order to ensure effective integration of forestry into national development. This paper reviews relevant policy linkages in the forestry sector, policy applications of forestry accounts, and challenges to their implementation. It argues for the need to develop regional or local accounting methods providing social, environmental, and economic data to allow assessment of the combined impacts of different public policies. It emphasizes the urgency of strengthening the management capacity of public agencies in dealing with complex policy networks addressing sustainable and multifunctional forest management.     

靖远松叶蜂的发生与治理

靖远松叶蜂（Ｄｉｐｒｉｏｎｊｉｎｇｙｕａｎｅｎｓｉｓ）是近几年发现为害油松的一新种叶蜂。１９９０年在山西省沁源县发现以来，发生面积逐年迅猛扩大，到１９９６年已达９．３８万ｈｍ２，为害空前猖獗。１９９１年—１９９４年山西省连续四年进行防治，取得了较好的防治效果。该文简要介绍了靖远松叶蜂在山西省的发生与防治概况，并提出了靖远松叶蜂综合治理措施。     

割草机器人工作原理及试验研究—基于GPS/DR组合导航系统

随着国民经济不断发展,我国人民生活水平不断提升,多种人工作业逐渐被机器所取代。GPS/DR组合导航系统能够有效提升割草机器人定位精度,克服传统割草机器人固有弊端,提高工作效率。为此,对GPS/DR组合导航系统原理展开了分析,进行了GPS/DR组合导航系统割草机器人研究,并进行了相关试验研究,验证了GPS/DR组合导航系统割草机器人相对于传统割草机器人的优势。     

Integrated use of organic and inorganic inputs in wheat-fodder maize cropping sequence to improve crop yields and soil properties

A 2-year field study was conducted to evaluate the effect of two organics, farmyard manure and vermicompost, each at three rates (0, 5, 10 t ha^?1 and 0, 1, 2 t ha^?1, respectively), along with two levels of mineral fertilizer (75% and 100% of recommended dose), on crops yields and soil properties under a wheat–fodder maize cropping sequence. Individual addition of organics at a higher level increased yields of wheat and subsequent maize. Soil microbial biomass carbon was enhanced as both a direct and residual effect with the addition of farmyard manure followed by vermicompost and fertilizer treatments, and also by combined addition of manure with either vermicompost or mineral fertilizer. Farmyard manure increased the availability of soil macro- and micronutrients, whereas vermicompost influenced only the availability of micronutrients at wheat harvest. A residual effect of farmyard manure and mineral fertilizers was found for available N. Meanwhile, the residual status of micronutrients in the soil was either maintained or significantly improved due to organic amendments (Mn and Zn with farmyard manure; Fe and Zn with vermicompost). Interaction of farmyard manure and vermicompost at a higher level benefited the next crop by increasing the yield of fodder maize and improving the availability of P and metals in soil.

河套灌区套种模式下综合作物系数的试验研究

依据FAO56作物需水量指南提供的作物系数计算方法,分别计算了内蒙古河套灌区磴口试验站小麦套种覆膜玉米、小麦套种未覆膜玉米、小麦套种油料向日葵3种套种模式下的综合单、双值作物系数。结果表明,3种套种模式下的作物在全生育期内均可迎来2次综合需水高峰;共生阶段的作物系数,单值方法高于双值方法的计算结果,而单一作物独立生长阶段,双值方法高于单值方法的计算结果;无论单值计算还是双值计算的套种作物田间综合ET,当单一作物处于独立生长期时差别不大,而2种作物共同生育阶段的差别较大;将3种作物在套种模式下的生育阶段划分的更加详细并分别命名,为套种模式下作物蒸散量提供更准确的计算依据。

Emerging Markets for Ecosystem Services

Abstract

Four main areas of learning were pursued during this exploration of die emerging markets for ecosystem services. First, die markets in Panama are dominated by the Panama Canal Authority and by timber revenues. Any strategy for expanding ecosystem services markets will have to reflect diese realities. Second, while the scientific and business components of die framework we used to analyze diese markets covered all the key points, more work needs to be done on die policy component. Articulating a simple, yet effective approach for developing policy recommendations to improve ecosystem services markets in context remains a key need. Third, valuable lessons were learned about ensuring tiiat the students capture die maximum benefits from an international, clinically-based field trip. Finally, interdisciplinary teaching/ research benefits dramatically from botii a focus on a single problem and recognition that the key challenge is turning complex scientific knowledge into accessible, good advice.
