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.原来这就是爱一个人。According to the official website of China Quality Certification Center, since June this year, 8 5G mobile phones have obtained 3C certification.赵文华点头应允：庞将军此番军功赫赫，大可放心。　　半年后，潜逃在外的陈步森秘密潜回樟城，住在女朋友刘春红处，终日惶恐度日，但没想到却意外碰到李寂之子淘淘，而这个当时与他曾做过游戏的孩子居然没有认出他来，他从淘淘的老师口中得知李寂的妻子冷薇因受到丈夫惨死的打击而住进精神病院，这让他产生接近冷薇的幻想，一方面他怜悯这个让他心动的女人，另一方面如果冷薇也没有认出他来，就意味着他最终的安全。本剧故事基于Al Ruddy在电影《教父》中从未公开的制片经历创作。　　上世纪90年代，从宁夏贫瘠甲天下的西海固地区搬迁到玉泉营地区的移民们，从无到有地建设着他们的新家园，村干部马得福（黄轩 饰）操心着通电、灌溉用水等桩桩件件的问题，他足够努力，却不自信未来什么时候来。直到国家新的扶贫政策出台，福建对宁夏的扶贫事业进行对口援助，并建立了合作样板闽宁村，陈金山（郭京飞 饰）、凌一农（黄觉 饰）等一批优秀的福建干部、技术人员为闽宁镇洒下奋斗的汗水，帮助得福找到了未来的方向，白麦苗（黄尧 饰）、马得宝（白宇帆 饰）、李水花（热依扎 饰）等村里的年轻人也通过劳务输入、发展庭院经济等收获了自信。在发展的过程中，传统与现代，物质文明与精神文明，寻根与断根等问题不断突显，对于马喊水（张嘉益 饰）、白校长（祖峰 饰）、李大有（尤勇智 饰）这些上一辈的人们而言，挑战和转变也在不断发生着。从西海固走出的人们没有忘记他们的初心，他们没有断根，而是把根扎在了这片更肥沃的地方，互相扶持着走上了康庄大道
