Short persistence of renovated pastures is a major problem for pastoral production systems. Pasture species establishment, species performance and persistency and their relationships with soil–water attributes following pasture improvement methods were evaluated over two years. Fertilised naturalised pasture (FNP), non‐fertilised naturalised pasture (NFNP), Lolium perenne–Trifolium repens cultivated pasture (CP), L. perenne–T. repens direct‐drilled pasture (DP), and Bromus valdivianus, Holcus lanatus, Dactylis glomerata, L. perenne and T. repens direct‐drilled pasture (DDP) were established as a randomised complete block design. Pastures were limed, fertilised and sheep‐grazed. Plant growth compensatory mechanisms, by decreasing tiller number and increasing tiller size, equalised pasture yield during the establishment. In both years, the improved pastures yield was greater than that of NFNP. In the second year, DDP and FNP reached the higher pasture growth rate, with a seasonality diminishment. During the second summer, soil matrix potential at 0–20 cm soil profile exceeded the permanent wilting point, resulting in the pasture growth rate of NFNP and the sown pastures ranging from 0.0 to 3.6 kg DM/ha per day, while for FNP, it was 17.8 kg DM/ha per day. Sown species, fast‐growing species spontaneous colonisation and growth were all stimulated in the improved pastures over species that tolerate stress, improving agronomical and ecological pasture features.

温带退化牧场的牧场恢复改良方法以及气候季节对土壤-牧场复合体的影响

翻新过的牧场的持续时间短是牧草生产系统的主要问题。在过去的两年中，对牧场种类的建立，种类性能和持久性及其与牧场改良方法后与土壤水属性的关系进行了评估。受精归牧草（FNP），未受精归牧场（NFNP），黑麦草-白三叶人工草地（CP），黑麦草-白三叶草直接钻出的牧草（DP），和雀麦valdivianus，绒毛草，鸭茅肾小球，紫苏和白毛丹建立直接钻进牧场（DDP）作为随机完整块设计。牧场被撒石灰，施肥和放牧绵羊。通过减少分er数量和增加分er大小，植物生长的补偿机制使建立期间的牧草产量均等。在这两年中，改良后的牧草单产都高于NFNP。在第二年，DDP和FNP达到了较高的牧草生长速度，且季节性减少。在第二个夏季，土壤剖面在0–20厘米土壤剖面上的潜力超过了永久的枯萎点，导致NFNP的草场生长速率和播种的草场每天介于0.0至3.6 kg DM / ha，而FNP则为每天是每天17.8千克DM /公顷。播种
