Ramie Urticaceae the Boehmeria, traditionally as a fiber crop. Higher protein content of ramie and has a medicinal effect, ramie feeding value in recent years also increasingly pay attention, but there is a lack of systematic research. The collection 20 of ramie varieties of resources (local resources and the introduction of nine from the Institute of Chinese Academy of Agricultural Sciences hemp used as feed 11 ramie resources) as the test material, feed nutrition, forage the Ramie resources from the systematic study of biological characteristics, agronomic traits, yield, quality, palatability, cultivation techniques, to provide a theoretical basis and practical application of basic forage development ramie. The results show that: (1) of the 20 copies of forage ramie resources from the growth period and botanical features fresh yield, daily growth rate, dry matter, number of stems, nutritional analysis and other aspects of forage resources of ramie varieties screening First, in terms of biological characteristics and botanical features can be divided into three categories. First class leaf, petiole color, stem color are green, the second class of the petiole color, stem color is pink or red, the third type of leaf, petiole color, stem color, some green, some are red more promiscuous. Followed by choosing the fresh yield, dry matter daily growth rate, the number of stems, the average grass layer height, the content of crude protein, neutral detergent fiber, acid detergent fiber, relative forage value of nine indicators using DPS statistical methods for clustering The analysis can be divided into two broad categories. The initial screening of three different botanical features of high-quality forage ramie varieties resources calm ramie, the ramie 2, Stone Guanyin ramie. (2) three Jiaoyou to forage ramie varieties of nutritional quality analysis results show: preliminary evaluation of higher feeding value of forage ramie contains 17 kinds of amino acids, total amino acids were higher than the control in feeding limonene No. 1, while close to or exceed the FAO / WHO reference protein pattern E / T ratio value of about 40% and the E / N ratio should be 0.6 or more. Different kinds of amino acids content in order to calm ramie and ramie 2 higher. CP, EE, Ca, RFV four indicators preliminary evaluation thirds forage ramie resources to the highest two indicators of the ramie the 2nd highest calm ramie Mg, K. Comprehensive evaluation of the calm and Ramie our ramie No. 2 better quality. (3) the impact of different height and mow green growth period of calm ramie Forage Quality analysis indicators involving CP, EE, Ca, Mg, NDF, ADF, RFV and other indicators, the results show that the leaf crude protein content and relative feeding value were higher than the stems, three different mow Green highly processed stems and leaves mow green 50cm handle the highest crude protein content. The flowering stage measured CP, Ca, Mg, RFV | four indexes content higher than tillering, measured EE, NDF, ADF content of three indicators below tillering stage. (4) forage ramie as the test of meat rabbit feed palatability evaluation and feed the velocity evaluation methods, preliminary evaluation of calm and ramie palatability 5A, the average feed speed for the first hour of 1.76g / min · only day 132.27g / average feed intake, slightly lower than the hybrid Pennisetum, slightly better than the control species feeding limonene, fared better. (5) The high-yield cultivation of the three factors and three levels orthogonal experiment to study the preliminary results of the test showed that the optimal treatment combinations of the test should be more fodder from ramie varieties calm ramie, best fertilization capacity of 300kg per hectare of urea, Kariya green height 90cm highest yield for forage ramie further promote theoretical and practical basis.
