【摘要】：近年來,隨著我國經(jīng)濟的快速發(fā)展,中國南方林下經(jīng)濟產(chǎn)業(yè)取得了蓬勃的發(fā)展,向社會提供了源源不斷的綠色林產(chǎn)品和生態(tài)產(chǎn)品。目前,我國草飼料需求量正在逐年增加,但我國林草產(chǎn)業(yè)遠未達到應(yīng)有的水平,還不能滿足市場需求,導(dǎo)致實際產(chǎn)量與市場需求量相差較遠,我國仍需從國外進口草飼料產(chǎn)品。尤其是我國南方地區(qū),飼草種植分散,飼草加工設(shè)備較少,規(guī)�；a(chǎn)難以實現(xiàn),大部分飼草得不到有效利用。本文緊密結(jié)合國家林業(yè)公益性行業(yè)科研專項“南方林下飼用植物開發(fā)利用關(guān)鍵技術(shù)研究(No.201204610)”和湖南省科技廳科技計劃重點項目“南方林下飼用植物壓塊機研制及應(yīng)用(No.2014NK2005)”開展研究,通過對林下飼用植物的飼草壓制加工技術(shù)、產(chǎn)品品質(zhì)鑒定技術(shù)、飼草壓塊過程流變學(xué)研究和動物喂飼配方等方面的系統(tǒng)研究,為南方林草產(chǎn)業(yè)發(fā)展提供了有力的理論依據(jù)和實驗支撐,具有重要的科學(xué)價值和應(yīng)用前景。本文主要研究工作及創(chuàng)新性成果如下：首先,對南方林下飼用植物壓制工藝進行了探索研究。從南方林下飼草的干燥過程、壓塊參數(shù)設(shè)置、草塊貯藏方式等方面進行了實驗研究和數(shù)據(jù)分析。實驗表明在100℃采用烘干箱法烘干速率最快,壓扁莖桿后所得到的干草質(zhì)量最好,并得到了最優(yōu)壓塊參數(shù)設(shè)置結(jié)果,貯藏方法上真空貯藏效果最好。同時我們可以采用微波爐法代替烘箱法進行飼草含水率的測定,并將多種干燥方法結(jié)合使用以對新鮮刈割的飼草進行干燥,將飼草粉碎壓塊也可顯著增大草塊密度,改善飼草成品喂飼口感。其次,對壓塊前后及貯藏半年后的六種南方林下飼用植物及飼草產(chǎn)品進行了連續(xù)營養(yǎng)成份測定,研究表明壓塊前后南方林下飼用植物營養(yǎng)成份變化不大,但貯藏半年后其營養(yǎng)成份含量有所降低,6種林下飼用植物的營養(yǎng)價值大小依次為：三葉草紅薯藤玉米草黑麥草蘇丹草百喜草。在此基礎(chǔ)上,研制出24個動物用精飼料喂飼配方和6個牛、羊用粗飼料配方,并申請獲批企業(yè)標準1個。再次,對不同壓塊壓強及不同壓塊溫度下紅薯藤與百喜草壓縮蠕變過程進行了研究,發(fā)現(xiàn)[M]|[N]流變模型能較好的擬合蠕變過程,利用Origin7.5進行擬合,擬合曲線與實驗曲線的決定系數(shù)(R2)均在0.95以上,并得到了不同壓塊壓強和不同壓塊溫度下紅薯藤與百喜草的壓縮蠕變本構(gòu)方程。最后,本文討論了蠕變實驗與松弛實驗的等價性,通過不同壓塊壓強下紅薯藤與百喜草蠕變曲線推導(dǎo)出紅薯藤與百喜草在一定應(yīng)變條件下的松弛曲線。本文研究結(jié)果對規(guī)�；_發(fā)林下經(jīng)濟資源、擇優(yōu)種植林下飼草、草塊流變壓制工藝、飼草營養(yǎng)成份測試分析及動物喂飼配方應(yīng)用研究等方面進行了有益探索,具有明顯的社會經(jīng)濟效益和廣闊的開發(fā)應(yīng)用前景。
[Abstract]:In recent years, with the rapid development of China's economy, the economic industry under forest in southern China has made vigorous development, providing a continuous stream of green forest products and ecological products to the society. At present, the demand for grass fodder in China is increasing year by year, but the forestry and grass industry in our country is far from meeting the market demand, which leads to the difference between the actual output and the market demand, and our country still needs to import forage products from abroad. Especially in southern China, forage grass planting is scattered, forage processing equipment is less, scale production is difficult to realize, most forage grass can not be effectively utilized. This paper closely combines with the national forestry public welfare industry scientific research project "the Research on the key Technology of the Development and Utilization of Southern Forest fodder Plant No. 201204610" and the key Project of Science and Technology Plan of Hunan Provincial Science and Technology Department "the Development of Southern Forest undergrowth Plant Press" and Application No. 2014NK2005) " The systematic research on forage processing technology, product quality identification technology, rheology study of forage block process and animal feeding formula of undergrowth forage plants were carried out. It provides a strong theoretical basis and experimental support for the development of forestry and grass industry in southern China, and has important scientific value and application prospect. The main research work and innovative achievements are as follows: firstly, the forage plant suppression technology of southern forest was studied. The experiment and data analysis were carried out on the drying process of forage under southern forest, the setting of block pressing parameters and the storage mode of grass block. The results showed that the drying rate of drying box was the fastest at 100 鈩，
