甘肃省中部地区小黑麦与饲用豌豆混播草地的生产性能及营养价值研究

Studies on the production performance and nutritional value of triticale and pea mixture grassland in central Gansu Province

摘要:

【目的】 筛选出甘肃中部地区最适宜与饲用豌豆混播的小黑麦品种。【方法】 以小黑麦品系 C23、甘农2号小黑麦和饲用豌豆（Pisum sativa）为试验材料，测定并比较临夏县3个地区甘农2号小黑麦单播、甘农2号小黑麦与饲用豌豆混播、小黑麦品系C23与饲用豌豆混播的草产量和营养品质。 【结果】 禾豆混播效果明显优于单播；甘农2号小黑麦与饲用豌豆混播时，CP含量（12.87%）和综合评价值均最高（0.77）；在安家坡试验点不论选择哪种种植模式，其生产性能与营养价值的综合评价值均最高（0.60）；从试验点和种植模式的交互作用看，在漫路乡种植甘农2号小黑麦与饲用豌豆混播时综合评价值最高（1.00），干草产量（7.15 t/hm2）较高，CP含量（13.87%）最高。【结论】 漫路乡和安家坡乡试验点适合甘农2号小黑麦与饲用豌豆混播，尹集镇适宜小黑麦品系C23与饲用豌豆混播。

Abstract:

【Objective】 This study aimed to identify the most suitable triticale varieties for mixed sowing with pea in central Gansu Province.【Method】 Triticale （×Triticale Wittmack） line C23，triticale variety Gannong No. 2 and pea （Pisum sativa） were used as experimental materials in this study. The forage yield and nutritional quality of monocropping triticale variety Gannong No. 2，mixed sowing of triticale variety Gannong No. 2 and pea，and mixed sowing of triticale line C23 and pea-were evaluated across three regions in Linxia County.【Result】The effect of legume-grass mixtures was better than that of monoculture. When triticale variety Gannong No. 2 and pea were mixed sowing，regardless of the experimental sites，the crude protein （CP） content （12. 87%） and comprehensive evaluation value （0. 77） were the highest. When planting at the Anjiapo town experimental site，regardless of the planting patterns，the comprehensive evaluation value （0. 60） was the highest. From the interaction of the experimental sites and planting patterns，the CP content （13. 87%） and comprehensive evaluation value （1. 00） of the triticale variety Gannong No. 2 and pea mixed sowing were the highest in Manlu town experimental site，and the hay yield （7. 15 t/hm2） was also higher.【Conclusion】 The experimental sites of Manlu town and Anjiapo town are optimal for the triticale variety Gannong No. 2 and pea mixed sowing，while Yinji Town is better suited for mixed sowing of triticale line C23 and pea.
