Humic acid active organic compound fertilizer , according to the principle of balanced fertilization , application of advanced technology , research and development of new fertilizers , consisting of : calcium , magnesium , sulfur , zinc , boron , iron , manganese , silicon and other trace elements 活性有机腐植酸复合肥,根据平衡施肥原理,应用高科技方法,研究、开发的新型肥料,内含:钙、镁、硫、锌、硼、铁、锰、硅等中微量元素。
The decision support system for rice ecological balanced fertilization is based on the theory of ecological balanced model , using the technical system of the utility and new advanced technology , achieving the new compute - fertilization - system about the ecological balanced fertilizer 水稻生态平衡施肥决策支持系统是以生态平衡施肥模型为理论基础,以实用和高新技术优化组装的技术体系为实现手段,以生态型肥料为载体的新的计算机施肥体系。
The model of rice ecological balanced fertilization is based on the conservation of mass and the relation of transmuting of the availability nutrition , the balanced fertilization is the best combination of fertilizer input which can meet the needs of high quantity , low investment , none - pollution , and so on 生态平衡施肥模型是建立在质量守恒定律和有效养分转化关系的基础上,生态型肥料是同时满足高产、低投、没有污染等多目标的最佳肥料投入组合。
The design of the decision support system for rice ecological balanced fertilization keeps to the life - period method of the software engineering , be designed phases , the summary design project of the whole system was brought forward by using the configurable analyses method , during decision support system design and realization , first analyze the flow of rice ecological balanced fertilization , and plot the database stream chart of rice ecological balanced fertilization , then adopt the data stream analysis method to bring forward sub - system function configuration table 水稻生态平衡施肥决策支持系统的设计遵循软件工程的生命周期法,分阶段设计开发,用结构化分析方法提出整个系统概要设计方案。在决策支持系统的设计与实现中,首先分析现行水稻生态平衡施肥的流程之后,绘制了决策支持系统的数据流图,然后采用数据流分析法,提出子系统的功能结构表,最后利用vb6 . 0 、 access2000数据库、多媒体技术等面向对象的编程工具,实现水稻生态平衡施肥决策支持系统的功能。
Professor wang zhoukang , with the school of bio - engineering , chongqing university , soil borne disease expert at home , was also invited to attend this symposium . he gave introduction of and communicated with other participants on types of soil borne diseases , their prevention and control methods and the program of research in fuling pickled mustard tuber soil borne disease . mr . feng wenqiang , expert with the sichuan academy of agricultural sciences , summarized the research findings in pengzhou on plasmodiophora brassicae club - root of cabbage by balanced fertilization 这次研讨会还同时邀请了国内土传病害专家,重庆大学生物工程学院的王中康教授对土传病害的种类防治方法和参加涪棱榨菜土传病害研究的科研项目给大家做了介绍和交流,四川省农科院的冯文强专家总结了几年来在彭州用平衡施肥的方法解决白菜根种病的研究结果。
