Abstract

Lasiurus sindicus Henr. is one of the most prominent grass species, occupying 80% area of the desert grassland. Average dry forage production of L. sindicus at the mature stage is 2.5–3.5 t ha⁻¹ (with 93% dry matter, 4.6% crude protein, 31% crude fiber, and 4.5% ash) and the carrying capacity of L. sindicus grasslands ranges from 0.8 to 1.2 active cattle units ha⁻¹ in the normal rainfall years. A large number of diazotrophs, as well as endophytes, have been found associated with L. sindicus rhizosphere, which play a crucial role in maintaining the plant-soil ecological interaction. L. sindicus has a prominent place as a perennial component in silvo-pastural, agro-pastural, agro-silvo-pastural, and horti-pastural production systems. Considering its importance, much emphasis should be given to utilization of L. sindicus based grasslands according to their carrying capacity and to avoid overgrazing.

摘要

Lasiurus sindicus Henr。是最突出的草种之一，占沙漠草原面积的80%。L. sindicus成熟期的平均干牧草产量为 2.5-3.5 t ha ⁻¹（干物质 93%，粗蛋白 4.6%，粗纤维 31%，灰分 4.5%），L. sindicus的承载能力在正常降雨年份，草地的范围为 0.8 到 1.2 个活跃的牛单位 ha ^{−1 。}已发现大量固氮菌和内生菌与L. sindicus根际有关，它们在维持植物-土壤生态相互作用中起着至关重要的作用。L. sindicus作为林牧、农牧、农林牧和园艺生产系统的多年生组成部分，它具有突出的地位。考虑到它的重要性，应根据其承载能力高度重视以L. sindicus为基础的草地的利用，并避免过度放牧。
