24个草木樨品种生产性能比较研究

24 Varieties of Sweet Clover Introduction Experiment Comparison

通过对24个草木樨品种种子质量、生产性能、营养成分等指标评定,筛选出适合当地推广的草木樨品种。吉林草木樨种子发芽率、发芽势极显著高于其它供试材料(P<0.01);株高、产量、粗蛋白、相对饲用价值也极显著高于其它品种(P<0.01),中性洗涤纤维极显著低于其他品种(P<0.01),粗脂肪含量居第二位,茎叶比、酸性洗涤纤维偏高;吉林草木樨净光合速率极显著高于其他供试材料(P<0.01),但其对水分利用效率较其他供试材料低。综合24个品种种子质量、生产性能、营养成分和光合生理指标,得出吉林品种为最佳推广品种、其次是5265、5210、4583。

Under the condition of field trials, 24 varieties of sweet clover the pros and cons of each index. By evaluating the seed quality, field production performance, laboratory nutrition indicators to determine which conform to the promotion of varieties of sweet clover. Jilin sweet clover seed germination rate, germination potential were significantly higher than other materials （P〈 0.01）; Plant height, yield and crude protein, relative forage value was significantly higher than other varieties （P〈 0.01）, Neutral detergent fiber significantly lower than other species （P〈 0.01）, Crude fat content in the second place, Cauline leaf ratio, acid washing fiber is on the high side; Jilin Net photosynthetic rate is significantly higher than other materials （P〈 0.01）, But the water use efficiency was lower than those of other selected materials. 24 species seed quality, production performance, nutritional physiological indexes, jilin varieties for best promotion varieties are obtained,the next is 5265,5210,4583.
