Synergistic Effects of Partial Substitution of Sludge with Cattle Manure and Straw on Soil Improvement and var. Growth in Horqin Sandy Land, China.

Afforestation with var. in northern China is hindered by soil degradation. This study evaluated a ternary amendment combining sewage sludge (SS), cattle manure (CM), and maize straw (MS) to rehabilitate degraded sandy soils in the Horqin Sandy Land.

Ecological effects of water and fertilizer addition on poplar-planting soil.

While irrigation and fertilization are basic cultivation practices in poplar plantations on a global scale, the impact of these practices on the environment is not well understood. Here, we demonstrate that water-urea addition and water-compound fertilizer addition differentially impact soil ecosystems. We report that water-fertilizer addition did not significantly alter taxonomic diversity indices, but it did drive significant shifts in microbial community composition, reflected by changes in the relative abundance of specific taxa and their functional profiles.

Effects of stand age and soil microbial communities on soil respiration throughout the growth cycle of poplar plantations in northeastern China.

Introduction: Many studies have identified stand age and soil microbial communities as key factors influencing soil respiration (Rs). However, the effects of stand age on Rs and soil microbial communities throughout the growth cycle of poplar ( cv.'I-214') plantations remain unclear.

Intercropping changed the soil microbial community composition but no significant effect on alpha diversity.

Introduction: Enhancing the planning of the forest-agricultural composite model and increasing the efficiency with which forest land is utilized could benefit from a thorough understanding of the impacts of intercropping between forests and agriculture on soil physicochemical properties and microbial communities.

Methods: × cv. and intercrop soils, along with their corresponding monocrops, were used in this study's llumina high-throughput sequencing analysis to determine the composition and diversity of soil bacterial and fungal communities.

[Surgical treatment of congenital heart diseases in pediatric patients with body weight less than 10 kg].

Objective: To report the experience of the surgical treatment of congenital heart diseases (CHD) in pediatric patients with body weight less than 10 kg.

Methods: Between January 2000 and December 2007, 105 children with CHD, aged 2 months to 3 years and weighing between 3.5 to 10 kg, underwent surgical treatment.
