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.凄清的胡琴声越来越远，凄苦落魄的青衫老人消失在月色中。1900 年的慕尼黑，野心勃勃的啤酒酿造商寇特·普兰克采用残忍手段，只为建造一个啤酒棚，在暴利的十月啤酒节上称霸。中秋宫宴上歌舞升平，皇上兴致颇高，封了领舞宫女萧萧为才人，后宫表面平静之下暗波汹涌。萧才人恃宠而骄宠冠六宫，除了行事不按套路之外，她与韦贵妃的关系更是微妙至极。一个新宠将立储国本搅动的不得安宁，“母凭子贵”的后宫“潜规则”是否会被打破？“女子本弱，为母则刚”，韦贵妃该如何自处？后宫这十里修罗场，一场没有硝烟的战争一触即发！该剧讲述上世纪三十年代初，日本占领中国东北三省，在一列从哈尔滨开往奉天的列车上，一方面日本人进行细菌战筹备中，秘密对相关生化专家及重要物资进行转移；另一方面南满伪政府中央银行将通过铁路秘密运送大批黄金，国民党特工乌鸦计划炸车夺金；除此之外，共产党秘密据点在此间也被乌鸦袭击，抗联特工队队长林胜男计划抓捕乌鸦。各方焦点汇集，在全长六百余公里的南满铁路沿线上演中国版火车大劫案。有些不好意思地笑着告诉他道：回皇上，那时小女子年幼，无知者无畏。
