【正文】 3)疫病綜合預防技術　　①養(yǎng)殖區(qū)環(huán)境和設施的防疫要求。保持圈舍清潔、干凈,冬暖夏涼。飼養(yǎng)要求:保持適度的營養(yǎng),防止營養(yǎng)過高或過低,保證正常生長發(fā)育和種用體況,按時發(fā)情、配種。冬天做好保暖防寒工作,防止舍內(nèi)溫度過低。根據(jù)肉豬的飼養(yǎng)標準,為其配制全價飼料,不限量飼喂,使肉豬肥育期短,屠宰率和出欄率高,周轉(zhuǎn)快,盈利多。首先要做好仔豬斷奶關,有利于仔豬生長發(fā)育,減少僵豬。實行產(chǎn)房分娩,做好產(chǎn)房保溫,為仔豬創(chuàng)造溫暖的小氣候環(huán)境,提高仔豬成活率。引進種豬時,應從具有種豬生產(chǎn)經(jīng)營許可的無疫區(qū)種豬場引進,引進品種必須優(yōu)良,具有本品種特征:按照GBl6567進行檢疫。2)懷孕母豬:指空懷母豬配種懷孕后至懷孕107天(產(chǎn)前7天),懷孕母豬實行單欄飼養(yǎng),該階段主要目的是防流產(chǎn)、防死胎,保證胎兒正常發(fā)育。遠離工廠和其他污染源,空氣清新,水質(zhì)優(yōu)良。xx市屬浙西丘陵山區(qū),自然環(huán)境十分優(yōu)越,全市行政區(qū)域面積中,耕地總面積258224畝,%,%,人均6畝。豬場地勢要求較高、干躁、平坦、背風向陽、有緩坡。同時帶動了xⅹ養(yǎng)豬業(yè)的發(fā)展,促進農(nóng)業(yè)的發(fā)展,幫助養(yǎng)豬農(nóng)戶增收,真正實現(xiàn)了雙贏,第五章 項目地點選擇分析本項目建設選址原則:充分利用己有條件,以較少投資,發(fā)揮較大的效益。2005年底,農(nóng)業(yè)部飼料工業(yè)中心通過深入的考察及周密的認證,正式將XⅹX飼料有限公司確定為中國(南方)乳豬飼料研究開發(fā)基地,同時與我公司展開全方位的合作研究,確定多種合作方向,2006年公司又被ⅹX省人民政府認定為“ⅹx省農(nóng)業(yè)骨干龍頭企業(yè)”,成為XX省乳豬飼料行業(yè)及xx市歷史上唯一1家省級農(nóng)業(yè)龍頭企業(yè)。本項目區(qū)臨近ⅹx、xx、xx、ⅹx等城市,交通便利,宜于新鮮瓜果蔬菜、花卉苗木貯運銷售。新品種多為彩葉樹種,因具有較強的色彩效果和較好的適應性,將逐漸拉大市場份額,如:紅葉石楠、金森女貞、大花六道木、地中海莢迷、小丑火棘、水果藍、亮綠忍冬,金焰繡線菊,金葉龜甲冬青等。容器大規(guī)格的容器苗處于嘗試階段,尚無批量可供市場。這一期間,%、 %。因此,提高產(chǎn)品的銷售量和附加值,是廣大菜農(nóng)和經(jīng)營企業(yè)面對的難題。在國際市場上,中國水果有較大的價格優(yōu)勢,我國的蘋果,梨,柑桔價格都比國際市場低40～70%,但水果出口尚不足國內(nèi)產(chǎn)量的4%,中國水果出口量也只占世界水果貿(mào)易總量的3%,市場空間十分廣闊。XX市生豬銷售市場立足于XX市本市和XX市。二是外來人口不斷增加,必須增加豬肉的供應。豬的綜合利用有待于深入開發(fā),豬產(chǎn)品國際市場尚須進一步開拓,養(yǎng)豬生產(chǎn)發(fā)展產(chǎn)景廣闊,確實是萬年青的產(chǎn)業(yè)。自繁自養(yǎng)是保持生豬生產(chǎn)穩(wěn)定,有效防控外來疫病,提高養(yǎng)豬經(jīng)濟效益和豬肉品質(zhì)的重要舉措,農(nóng)業(yè)部門積極鼓勵規(guī)模養(yǎng)殖場和養(yǎng)殖戶自繁自養(yǎng),增加飼養(yǎng)量,大力發(fā)展仔豬生產(chǎn),減少外來疫病的侵入,提高經(jīng)濟效益。全市還異地發(fā)展花卉苗木239,1公頃。XXXX現(xiàn)代生態(tài)農(nóng)業(yè)示范園中不少低丘緩坡,經(jīng)過改造可以新建成優(yōu)質(zhì)果園。XXXX現(xiàn)代化生態(tài)農(nóng)業(yè)示范園完全是遵照中共中央、國務院和省、市有關文件精神建設的,符合國家農(nóng)業(yè)發(fā)展政策。,%，,%。因此,豬肉需求在今后一定時期還將不斷增加,豬肉作為大眾肉類產(chǎn)品,其是否穩(wěn)定供應,直接關系到市場的穩(wěn)定和廣大百姓的利害關系,也是關系到社會穩(wěn)定的政治大事,但是,隨著城市化和工業(yè)化的發(fā)展,生態(tài)環(huán)境的控制,農(nóng)村發(fā)展生豬生產(chǎn)的空間不斷縮小,生豬生產(chǎn)的難度不斷增加,生產(chǎn)與需求矛盾日益突出。xxxx現(xiàn)代化生態(tài)農(nóng)業(yè)示范園的建設,在基礎設施、物質(zhì)裝備、生產(chǎn)技術、經(jīng)營管理等方面都體現(xiàn)了現(xiàn)代農(nóng)業(yè)的先進水平,所以本項目不僅是農(nóng)業(yè)科技和標準化生產(chǎn)示范推廣基地,而且也是農(nóng)業(yè)產(chǎn)業(yè)化經(jīng)營的樣板,因此,本項目建設,對于提高XX市農(nóng)產(chǎn)品質(zhì)量,提升農(nóng)業(yè)競爭力,具有十分重要的意義?！　「鶕?jù)中共xx市委、xx市人民政府《xx市發(fā)展都市農(nóng)業(yè)實施意見》(市委[2OO3]3號)的精神,xx市屬xx大都市的山區(qū)農(nóng)業(yè)圈,要依托豐富的山水資源和良好的生態(tài)環(huán)境,重點發(fā)展果、蔬菜、花卉苗木,畜禽等名特優(yōu)新農(nóng)產(chǎn)品基地,積極發(fā)展生態(tài)農(nóng)業(yè),因地制宜發(fā)展觀光休閑農(nóng)業(yè)。2006年,中國全國人大通過了《畜牧法》,為保證畜牧業(yè)的健康快速發(fā)展提供了強有力的法律保障,在2007年1月份,國務院發(fā)布了《國務院關于促進畜牧業(yè)持續(xù)健康發(fā)展的意見》,其中明確指出:“畜牧業(yè)是現(xiàn)代農(nóng)業(yè)產(chǎn)業(yè)體系的重要組成部分。第二章項目建設的必要性和可行性一是按照中央精神切實做好“三農(nóng)″問題,促進新農(nóng)村建設?！　?:本項目總投資為5000萬元,其中:生豬生態(tài)養(yǎng)殖區(qū)3500萬元、觀光果園區(qū)50萬元、科研、教學、培訓基地3SO萬元。生活、管理培訓)、科研、教學樓6000余平方米。新建生態(tài)農(nóng)業(yè)觀光園180畝。按“適度規(guī)模、標準化生產(chǎn)、產(chǎn)業(yè)化經(jīng)營、促進循環(huán)經(jīng)濟發(fā)展”的總體思路進行規(guī)劃設計和施工建設。Symbol is generally acknowledged to be one of the most frequently employed devices in poetry. In works of fiction it is no less frequent and no less important. The fact is that, when a reader reads a work of fiction, his focus is mostly cast upon the plot, the character, and the language used, so that the symbols are automatically backgrounded on the reader’s part. But in some novels and stories, the symbolism looms so large that the reader will fail to get a prehensive understanding of the work without paying special attention to the symbols. The Scarlet Letter by Nathaniel Hawthorne is one of such works. The very title points to a double symbol: the scarlet letter A worn by Hester conveys a multiple of senses which differ greatly from what it literally stands for, and the work eventually develops into a test and critique of symbols themselves. Thomas Pynchon’s V. continues along much the same line, testing an alphabetical symbol. Another example is Herman Melville’s MobyDick, in which the huge white whale in the title of the book acquires greater meaning than the literal dictionarydefinition of an aquatic mammal. It also suggests more than the devil, to whom some of the characters liken it. The huge whale, as the story unfolds, es to imply an amplitude of meanings: among them the forces of nature and the whole universe.As rhetorical device, symbol is different from metaphor, which is literally false but figuratively true. Unlike allegory, which represents abstract terms like “l(fā)ove” or “truth,” symbols are perceptible objects. In literature almost anything—particular objects, characters, setting, and actions—can be symbolic if the author wishes to make it so by either hinting or insisting that the material means more than it literally does. Symbols are suggested through special treatment such as imagery, repetition, connotative language, or other artistic devices. for instance, the ways sentences are connected. This is the internal organization of a text. Under context, roughly the material, mental, personal, interactional, social, institutional, cultural, and historical situation in which the discourse is made, we consider the external relations of the literary text or a part of the text, seeing it as a discourse presupposing a social relation between its participants (author and reader, character and character, character and reader, etc.), and a sharing of knowledge and assumptions by participants.General: Note whether any general types of grammatical construction are used to special effect (eg parative or superlative constructions, coordinative or listing constructions, parenthetical constructions, interjections and afterthoughts as occur in causal speech). And see to the number of lists and coordinations.Sentence plexity: Do sentences on whole have a simple or a plex structure? What is the average sentence length? Does plexity vary strikingly from one sentence to another? Is plexity mainly due to (i) coordination, (ii) subordination, (iii) juxtaposition of clauses or of other equivalent structures? In what parts of the text does plexity tend to occur?Verb phrases: Are there any significant departures from the use of the simple past tense? For example, notice occurrences and functions of the present tense, of the progressive aspect, of the perfect aspect, of modal auxiliaries.Tropes (foregrounded irregularities of content): Are there any obvious violations of or neologisms from the linguistic code? For example, are there any neologisms (such as “portentous infants”)? Are there any semantic, syntactic, phonological, or graphological deviations? Such deviations are often the clue to special interpretations associated with traditional figures of speech such as metaphor, metonymy, synecdoche, paradox, and irony. If such tropes occur, what kind of special interpretation is involved (for example, metaphor can be classified as personifying, animalizing, concretizing, synaesthetic, etc)?Symbol, in the simple
