In this paper, the main problem and countermeasure of fruit production quality and safety were studied in Yanshan Mountain. The subjective factor was fruit farmer quality and safety consciousness faint, and the objective factors were: severe orchard environmental pollution, faint fruit postharvest handling, lag in process technology, fruit quality determination and market inspection system is n...

This experiment was conducted to evaluation the effects of different levels of untreated and treated green grape leaf with urea on performance, egg quality traits and blood parameters of laying hens. In this experiment 192 Hy-Line (w-36) laying hens, 35 to 46 wk of age were divided in to 4 treatments with 4 replicates (12 birds per replicate) in a completely randomized design experiment. The tr...

The objective of this review is to compare the cost of coppice and longer rotation poplar harvesting technology. Harvesting technology for short rotation poplar has evolved over the years to address both coppice harvest and single-stem harvest systems. Two potential approaches for coppice harvesting are modified forage harvesters and modified mulcher-balers. Both of these systems effectively ha...

silver nanoparticles (agnps) are amongst the most investigated materials in nanotechnology in view of their unique physio-chemical features and applications in restorative science. their progressive usages in different fields of science besides some predominant restrictions with conventional methods for their synthesis have demanded analysts to discover green courses for their creation. biologi...
