【摘要】：为了研究新疆5种藜科一年生盐生饲草红叶藜(Chenopodium rubrum)、野榆钱菠菜(Atriplex aucheri)、盐地碱蓬(Suaeda salsa)、盐角草(Salicornia europaea)和高碱蓬(Suaeda altissima)的最佳刈割时期和相对饲用价值大小,对其3个不同生育时期(营养期、初花期和结实期)的营养成分含量进行测定分析。结果表明,5种植物在初花期营养价值最高,地上部生物量能够满足载畜需求,因此适宜在初花期开发利用;5种盐生饲草在初花期与苜蓿(Medicago sativa)相比,红叶藜的相对饲用价值最高,之后依次为野榆钱菠菜、盐地碱蓬、高碱蓬和盐角草。野榆钱菠菜、红叶藜和高碱蓬甜菜碱含量丰富,在7%左右,盐角草、红叶藜和野榆钱菠菜草酸盐含量超标。总之,这5种植物均具有一定的饲用开发利用价值,但盐分含量偏高不宜长期单一饲喂反刍动物。
[Abstract]:In order to study the optimum cutting time and relative feeding value of Chenopodium rubrumum, Atriplex aucherianus, Suaeda salsaa, Salicornia europaea and Suaeda altissima, five species of Chenopodium rubrumum, Atriplex aucheriani, Suaeda salsa, and Suaeda altissima. The contents of nutrient components in three different growth stages (vegetative period, early flowering stage and fruiting stage) were determined and analyzed. The results showed that the vegetative value of 5 species was the highest in the early flowering stage, and the aboveground biomass could meet the demand of carrying livestock. Therefore, it was suitable to develop and utilize the five salt forage grasses at the early flowering stage, compared with Medicago sativa at the early flowering stage, the relative feeding value of Chenopodium rubrum was higher than that of Medicago sativa. After that, it was followed by spinach, Suaeda salsa, Suaeda salsa and Salicornia salsa. The contents of spinach, Chenopodium mandshurica and betaine of Suaeda hirsutum were rich in about 7%, and the content of oxalate was higher than the standard. In a word, these five species of plants have certain value of forage development and utilization, but high salt content is not suitable for feeding ruminants alone for a long time.
