Dissemination is the most important stage during the agricultural plating , single - seed dissemination of crop , especially the wheat , the mealie etc , can improve the productivity , save seeds and fertilizer save time and then reduce costing , increase productivity 播种是农作物种植过程的重要环节，作物尤其是中耕作物的单粒点播具有增产增收、节种、省肥、省工、降低作业成本、提高劳动生产率等优点。
A kind of knew non - damage inspect method called app tester measuring the intensity of spray concrete was discussed in detail . a kind of non - damage inspect method used ultrasonic instrument and concrete instrument measuring the intensity of concrete lining was discussed . these method was proved to be impersonal and reliable , convenient for operating , laborsaving and timesaving 结合工程实践，详细阐述了一种新的喷混凝土强度无损检测方法? ?气压射钉枪检测喷混凝土强度，阐述了二次衬砌强度无损检测方法? ? “超声?回弹”综合法，验证了该方法具有检测结果客观可靠、操作方便、省工省时等优点。
There are several insect pests and diseases breaking out simultaneously in xiangshui county in 1998 while rice is in the ear . for integrated controlling these pests effectively as well as using less manpower and cost . we took such measures as taking account of all the major heading pests , selecting the appropriate insecticides and fungicides at the same time only once , which reaches the goal of overall - control pests . all of these measures are well received by local peasants 响水县98年水稻穗期多种虫害，病害并发、重发应采取的综合控制对策是在病虫害集中发生和防治适期内采取适当调佳用药时间，瞻前顾后，一药多用，多药合用，病虫兼治，主次突出，达到全面控制病虫害的目标，省工节本，深受群众的欢迎。
In order to decrease expenditure and increase total economic efficiency , the key technique consisted of a complete sets of base fertilizer heavily , stabilizing n , increasing p and k , herbicide , coordinating of irrigation , fertilization and dpc regulation in first - flowering time , water - saving by furrow irrigation , simple pruning of cotton plants , chemical accelerating the ripening and so on 以重施基肥，稳氮增磷增钾，化学除草，初花期水、肥、控同步，沟灌节水，简化整枝及化学催熟等项技术组装配套，达到节支省工，提高整体经济效益。
Recently , with the improvement of technology of communication , people do many research on power line carrier . power line composed the most common net because it connects every home and family . people need not to build other communication channel and provide special radio frequency for it when using power line to transfer data and information 近年来随着通信技术的发展，人们在电力线载波通信方面作了大量的研究工作。电力供电网络四通八达，低压电力线连接千家万户，构成最普及的网络。利用它进行数据通信，传递各种信息，不占用无线频道资源，亦无需铺设专用通讯线路，省工、省钱、维护简单、有着广阔的前景。
Based on the waste residue continuing to use the theory of pure gypsum as amendment in improving alkaline soil establish a plan that with saving resources , water and with better effect and rapid speed . reach on the effect of the same - ion effect and salt effect of nacl in course of improving the alkaline soil . then after the certain amount of gypsum for exertion is decided , compare the effect of exertion of waste residue for one time with for more than one time 首先比较煤烟脱硫废渣与化学纯石膏改良的物理化学过程的异同，在废渣基本上可以沿用纯石膏改良的理论基础上，在一定的计划改良深度内，定量的石膏施用方法的情况下，建立一个省石膏，省水，省工，效果好，速度快的方案；同时研究了nacl的盐效应和na _ 2so _ 4的同离子效应在纯石膏改良碱土过程中起到的作用；最后针对石膏施用量确定之后，一次施入还是分次施入更好，进行了探讨；结合当地耕作条件，总结各有利的技术措施，指导田间的生产实际。
