Soil fertility differences due to tillage methods modulate maize yield formation at different planting densities.

To address the problems of planting density and low soil nutrient content in maize cultivation and production in western Inner Mongolia. This study aims to elucidate the regulatory mechanism by which soil fertility augmentation affects maize yield formation under a variety of planting densities. In this study, nine soil fertility conditions were established by deep tillage, no-tillage and in situ straw return.

Effects of different straw return methods on soil properties and yield potential of maize.

Long-term continual straw return can enhance soil quality and increase crop yields by perpetually altering the soil environment. However, little is known about how different straw return methods affect soil physicochemical properties, enzymatic processes, and crop yields. The study aims to determine how different straw return practices improve soil structure, nutrients, enzyme activities, and maize yields.

Regulation of tillage on grain matter accumulation in maize.

Introduction: To address issues related to shallow soil tillage, low soil nutrient content, and single tillage method in maize production in the Western Inner Mongolia Region, this study implemented various tillage and straw return techniques, including strip cultivation, subsoiling, deep tillage, no-tillage, straw incorporation with strip cultivation, straw incorporation with subsoiling, straw incorporation with deep tillage, and straw incorporation with no tillage, while using conventional shallow spinning by farmers as the control.

Methods: We employed Xianyu 696 (XY696) and Ximeng 6 (XM6) as experimental materials to assess maize 100-grains weight, grain filling rate parameters, and grain nutrient quality. This investigation aimed to elucidate how tillage and straw return influence the accumulation of grain material in different maize varieties.

Community succession and functional prediction of microbial consortium with straw degradation during subculture at low temperature.

To systematically explore and analyze the microbial composition and function of microbial consortium M44 with straw degradation in the process of subculture at low temperature. In this study, straw degradation characteristics of samples in different culture stages were determined. MiSeq high-throughput sequencing technology was used to analyze the evolution of community structure and its relationship with degradation characteristics of microbial consortium in different culture periods, and the PICRUSt function prediction analysis was performed.

Potentials of straw return and potassium supply on maize (Zea mays L.) photosynthesis, dry matter accumulation and yield.

Maize (Zea mays L.) is considered one of the most important grains in the world. Straw return has the effect of reducing soil bulk density and increasing soil porosity.

Regulation of subsoiling tillage on the grain filling characteristics of maize varieties from different eras.

Grain filling is the key stage for achieving high grain yield. Subsoiling tillage, as an effective conservation tillage, has been widely used in the maize planting region of China. This study was conducted to explore the effects of subsoiling on the grain filling characteristics of maize varieties of different eras.

Phospholipid-based ultrasonic microbubbles for loading protein and ultrasound-triggered release.

Background: Ultrasonic microbubbles are used as ultrasound-triggered delivery carriers for protein drugs.

Aim: This work was to prepare stabilized protein-loaded phospholipid-based ultrasonic microbubbles (PUM) and to determine its value as a protein delivery system.

Method: Bovine serum albumin (BSA) was used as a model protein drug.

[The prevalence of J wave in apparently healthy subjects in Hubei province of China].

Objective: To observe the prevalence of J wave in apparently healthy subjects in Wuhan.

Methods: The study subjects comprised of 1817 apparently healthy subjects (1131 males, mean age 46.38 +/- 15.

Characteristic of the prevalence of J wave in apparently healthy Chinese adults.

Background: The J wave has been seen in idiopathic ventricular fibrillation, Brugada syndrome, and early repolarization syndrome. Although these conditions share some ECG features, the clinical consequences are markedly different. J wave presentation in healthy subjects is not a rare phenomenon, although its characteristics are poorly understood.
