10-15% of aquatic plants and hidden objects are planted shallowly at the edge of the pond to create an environment for lobsters to inhabit and shell and reduce mutual killing. The influence of water quality on lobster yield cannot be ignored. During the breeding process, the PH value of the pool water is kept between 7.5 and 8.5, and the transparency is 30-40cm. Fresh water should be added frequently, quicklime solution should be splashed regularly, water quality should be adjusted, and diseases and shelling failure should be prevented. 2. Feed feed reasonably. Lobsters will kill each other when hungry and under-fed, so the feeding amount must be sufficient. Lobster feed is animal and plant feed. Plant feeds are wheat, aquatic plants, rapeseed cakes, etc. Animal feeds are miscellaneous fish, miscellaneous meat, livestock viscera, etc. At ordinary times, the feeding time, feeding amount and feeding method are determined according to the habit of lobsters falling in the day and coming out at night and the density of lobsters in the pond. 3. Scientific fishing. Young shrimps can grow to commercial specifications in 60-90 days under the condition of suitable temperature and sufficient feed. The seedlings will be released in March and will be caught in rotation around June, selling large ones and keeping small ones.Stage 2: Become Serious//234秦淼将信搁在一旁。　　松尾铃木与女优的30分钟开始在憧憬的人手下工作的青叶，虽然对于第一次的工作感到困惑，但在以光为首的充满个性的前辈社员的帮助下一点一点地成长着。讲述了关于医药研究的故事，在一个“源计划”实验室，裘佳宁（宋茜饰）和周小山（罗云熙饰）相遇，可周小山的真实身份却是一名掮客，他的到来是要夺走裘佳宁的科研成果，佳宁对事业的执着和对国家的大义感染了周小山，最终佳宁和周小山一起完成了研究，为国家争光。
