塔尔巴克台山东段山区混播草地研究初报

Preliminary study on mix-sowed pasture in eastern section of Tal Barker Taishan mountain

以线叶豌豆（Vicia tenuifolia）、紫花苜蓿（Medicago sativa）、红豆草（Onobrychis viciaefolia）、猫尾草（Phleum pratense）、冰草（Agropyron cristatum）及鸭茅（Dactylis glomerata）6种豆禾牧草在混播种类为3、4、5和6种且豆禾混播比例为4∶6的建植3年的草地（T1～T6）为对象,研究其牧草抽穗/现蕾期、结实期和再生期的干草产量,粗蛋白、中性洗涤纤维和粗脂肪含量。结果表明,所有混播组合草地产量都显著高于紫花苜蓿单播（CK）（P〈0.05）,且多数混播组合牧草养分也高于CK。T2（线叶豌豆＋紫花苜蓿＋猫尾草＋高冰草＋鸭茅）和T1（线叶豌豆＋紫花苜蓿＋红豆草＋猫尾草＋冰草＋鸭茅）的产量和养分都优于CK,且T2居于各混播之首,T1次之。说明不同混播组合栽培草地在合理配置资源、增产和提高品质等方面都优于CK。T2和T1为最佳的豆、禾混播组合方式,适宜在当地和类似生境条件下推广建植栽培草地。

The present study analyzed the hay yield, Crude protein（CP）, Neutral Detergent Fiber （NDF） and Crude fats（CF） in herbage head sprouting/early budding, fructicative and regeneration stage with 3 a mix-sowed grassland constructed by six Legumionosae and Gramineae herbage （Vicia tenuifolia, Medicago sativa , Onobrychis viciaefolia , Phleum pretense, Agropyron cristatum and Dactylis glomerata ） with mix-sowed type numbers of 3,4,5,6 and proportion of 4： 6. The results showed that the hay yield of all the mix-sowed combinations grassland were significantly higher than that of CK （single sowed M. sativa） and the quality of most combination were higher than that of CK. The yield and nutrient of T2 （V. tenuifo- lia＋M, sativa＋P, pretense＋A, cristaturn＋D, glornerata） （P〈0. 05） and T1 （V. tenui folia＋M, sativa＋ O. viciaefolia＋P, pratense＋A, cristatum＋D, glomerata） were higher than that of CK, which had highest and second highest yield and nutrient of all mix-sowed combinations. The trial results stated that the different mix-sowed combinations pasture were better than CK in reasonable resources allocation and utilization and yield and quality increase. T2 and T1 were the best Legumionosae and Gramineae mix-sowed combinations which were suitable for construction artificial grassland in local and similar habitat conditions.
