【摘要】：苦荬菜種植田在第二年春季未播種的情況下仍出現(xiàn)呈條播狀、出苗整齊且具有較發(fā)達(dá)根系植株的現(xiàn)象。為了探究該現(xiàn)象是否由于蒙早苦荬菜品種發(fā)生變異,從而導(dǎo)致一年生苦荬菜繁生出越年生苦荬菜,本研究以蒙早苦荬菜(Lactucaindica.Cv.Mengzao)為研究對象,分別從農(nóng)藝性狀、葉片分布、營養(yǎng)成分、種子活力及根系特性幾個(gè)方面對當(dāng)年種植及疑似越年生的苦荬菜植株進(jìn)行比較分析。研究結(jié)果發(fā)現(xiàn),從根系越年返青后的活力上來看,蒙早苦荬菜不具備越年生特性。在苦荬菜田內(nèi)發(fā)現(xiàn)的疑似越年生植株實(shí)際為秋季種子自然落粒形成的宿存根早春返青后形成的植株。在苦荬菜種植過程中發(fā)現(xiàn),其植株有黃花、白花之分。為了確定不同花色苦荬菜在利用過程中是否存在差異,針對不同花色蒙早苦荬菜的農(nóng)藝性狀、葉片分布及營養(yǎng)成分等方面進(jìn)行對比,結(jié)果表明不同花色苦荬菜在利用過程中不存在顯著差異。為進(jìn)一步對蒙早苦荬菜加以利用,本論文采用青貯塑料袋模擬青貯方式,探索蒙早苦荬菜的最適青貯加工技術(shù)。本研究通過新鮮苦荬菜直接青貯、苦荬菜預(yù)干后青貯以及將新鮮苦荬菜與預(yù)干苦荬菜分別與全株玉米按不同比例(1:1、1:2、1:3、2:1、3:1)混合青貯等不同青貯方式,分別測定不同處理的營養(yǎng)品質(zhì)及發(fā)酵品質(zhì)。結(jié)果表明:預(yù)干處理未顯著改善苦荬菜青貯飼料品質(zhì);新鮮苦荬菜與全株玉米最適的混合青貯比例為1:2;預(yù)干苦荬菜與全株玉米最適的混合青貯比例為1:3。
[Abstract]:Under the condition of no seeding in the second spring, Ixeris indica was still in the form of strip seeding, the emergence of plantlets was neat and had more developed root plants. In order to find out whether this phenomenon is caused by the variation of Lactucaindica.Cv.Mengzao. in order to find out whether the variation of Lactucaindica.Cv.Mengzaois is the reason of the variety variation of Lactucaindica.Cv.Mengzao. in this study, the characters of agronomic characters, leaf distribution and nutrient composition were studied in Lactucaindica.Cv.Mengzao. Seed vigor and root system characteristics were compared between current year planting and suspected annual plantlets of Ixeris indica. The results showed that Ixeris mongolicus did not possess the characteristics of annual growth from the point of view of the vigor of roots returning to green. The suspected annual plants found in the field of Ixeris indica L. were actually the plants formed by natural seed falling in autumn after returning to green in early spring. It was found that there were yellow flowers and white flowers in the plant of Ixeris indica. In order to determine whether there are differences in the process of utilization of Ixeris indica, the agronomic characters, leaf distribution and nutrient composition of Ixeris indica var. mongolica were compared. The results showed that there was no significant difference in the utilization of Ixeris indica. In order to make further use of Ixeris mongolica, the silage plastic bag was used to simulate the silage to explore the optimum silage processing technology of Ixeris mongolicus. In this study, different silage methods such as direct silage of fresh Ixeris indica, pre-drying silage of Ixeris indica and mixed silage of fresh Ixeris indica and Ixeris indica with whole corn in different proportion (1: 1: 1: 1: 1: 1: 2: 1: 1: 3: 1) were used in this study. The nutritional quality and fermentation quality of different treatments were determined. The results showed that the quality of silage of Ixeris indica was not significantly improved by pre-drying treatment, the optimum ratio of mixed silage of fresh Ixeris indica and whole corn was 1: 2, and the optimum ratio of mixed silage of predried Ixeris indica and whole corn was 1: 3.
