随着机械化生产水平的不断提高，水稻倒伏问题已经严重影响黑龙江省水稻生产。通过配合施用钾、硅肥和化学调控剂对防止水稻倒伏进行了初步研究，以期组装集成综合防倒伏调控技术，节省水稻生产成本、提高其产量和品质。结果表明：钾肥或硅肥单独施用时防倒伏效果不理想，硅肥（500 kg/hm2）只有与高量钾肥（400 kg/hm2）混合施用时才有较好的防倒效果；30％矮壮烯效剂（1．2 L/hm2）对防倒伏有明显作用，当配合钾硅肥施用时防倒效果更好。抗倒处理降低了第1，2，3节间的长度，改善了易发生倒伏的第3节间的物理性状，增加其节间干质量和茎壁厚度。抗倒处理使每穗1，2次枝梗数增多，从而使每穗粒数增多，产量明显增加。钾硅肥与氮磷肥配合施用，并在水稻拔节前7 d喷施30％矮壮烯效剂，是一项较好的综合防倒调控栽培技术。

With the continuous improvement of mechanization production level ,rice lodging issue has seriously affect rice production of Heilongjiang province .In this paper ,in order to assembly integrate comprehensive prevent lodging control technology ,save the cost of rice production ,improve the yield and quality ,the preliminary study on combining the potassium ,silicon fertilizer and chemical control agent to prevent rice lodging has carried on .Results show that when potash or silicon fertilizer applies individually ,lodging resistant effect is not good .Only silicon fertil-izer (500 kg/ha)mixed with high amount of potash fertilization (400 kg/ha) has good anti-lodging effect.Chemical control agent (1.2 L/ha)has obvious effect to prevent lodging .Effect of chemical control agent cooperate with po-tassium silicon fertilizer application to prevent rice lodging is better than that of chemical control agent application . Lodging resistance reason is mainly to reduce the length of the internod

微机防误闭锁装置是指在微机化管理变电所中值班人员在进行就地操作、遥控操作、程序操作等倒闸操作中为了防止误操作的重要技术措施。就变电所中防误闭锁装置的机械闭锁、电气闭锁、电磁锁闭、微机防误闭锁等防误闭锁功能相结合的运行方式为基础，对微机防误闭锁装置进行现场防误功能的可操作性分析。

On the basis of the operating methods with error-preventing functions,such as mechanical lock,electronic lock,electromagnetic lock and microcomputer error-prevent lock,this paper discusses the operating maintenance, reasonable improvement and illustrates the on-site error-preventing function with microcomputer five-guard system.

分析了调度操作业务安全防误管理的规范要求和当前主流的安全防误应用建设模式，提出了以调度倒闸操作流程及标准操作程序(SOP)为主线，在流程的不同环节调用相关安全防误校核的安全防误应用模式，并详细阐述了具体设计实现，将 SOP 的管理防误与安全校核计算等技术防误无缝融合，实现了调度操作业务的全过程安全防误。

An analysis is made of the dispatching operation business security mistake prevention management specification requirements and the current mainstream development mode of security anti-false application.It is proposed that the relevant anti-error safety application mode of anti-fault security check be called in different links of the procedures with the scheduling of switching operation procedures and the standard operation procedure (SOP) as the main line.And a detailed description of specific design and implementation is presented.The anti-error management of SOP is seamlessly blended with anti-false technology such as safety checking and calculation,realizing the anti-error safety of the whole procedure of dispatching operation business.
