Due to the high rolling rate of a regular crawler paddy harvester and absence mature first season products ratooning rice, combined with planting mode harvest requirements triangular rice is specifically designed. The structure steering principle chassis are described. hydraulic system simulated analyzed by AMESim2020 (Guangzhou, China) verify rationality its design; RecurDynV9R4 used simulate ...

Saccharum spontaneum is the major donor of important traits like vigour, hardiness and ratooning potential to modern sugarcane cultivars. Identifying      S. clones with high early vigour tillering ability essential include them in hybridization program. Forty three accessions were evaluated for number tillers per clump, stalk length, diameter, leaves on main stem, leaf leng...

objectives: we aimed to design, implement and evaluate the efficacy of a comprehensive course on non-clinical competencies that dentists must possess for a successful dental practice. materials and methods: in this interventional before-after study an expert panel of five academic staff members and five general practitioners derived the topics for a course on successful dental practice, and agg...

The mixtures, grains, and residues in the ratooning rice harvesting machine need to be conveyed forward, backward, upward, downward. Due such operations, often accumulation blockage take place at intersection of a horizontal-vertical screw conveyor, resulting low efficiency, high power consumption, even grain damage. In this study, CFD-DEM approach was applied address above problems. Firstly, p...

Sogatella furcifera (Horváth) (Hemiptera: Delphacidae) is the most serious pest on rice in southwestern China. Yunnan province is within this region and is a major overwintering area for S. furcifera in China. This field study was carried out over 4 yr (2010-2013) and focused on S. furcifera distribution, population density, and demography, as well as the relationship between various environmen...
