Wood ash production from power plants and the use of recycled ash for earthworks and forest peatland fertilization have increased markedly in Finland in recent decades. In this study, effects of wood...
Biochar (BC), the carbon-rich by-product resulting from pyrolysis of biomass, is used for bioenergy and increasingly as a soil additive for carbon sequestration and soil improvement. However, informat...
阐述了水稻高速插秧机前插式直齿双控制分插机构设计方法和工作原理,建立了机构的运动学分析模型,使用ADAMS软件对该机构的运动进行了优化和仿真,获得了分插机构的运动轨迹和运动特性曲线。结果表明该机构能够实现插秧时秧爪所需的主要运动学目标。
An on-farm experiment was conducted at Zanyokwe irrigation scheme (ZIS) in the Eastern Cape Province of South Africa (SA) to evaluate comparative performance of direct seeded and transplanted green ma...
In this paper I wish to explore an aspect of comparative labor law by examining the approaches to national labor law policy by the national governments of the three great common law federations of ...
针对水稻插秧机分插机构优化过程中的多目标、非线性、交互性、模糊性以及优化结果不唯一等问题,建立了运动学参数的计算模型,通过对插秧性能各要求的模糊化得出各要求的隶属度,同时提出了对干涉的判定方法。在以各隶属度最大化为目标,运用优化算法求得一组较优解的基础上对该组解进行了区间扩张,将区间搜索转换为多目标优化问题,再次运用优化算法并通过 Visual Basic 6.0软件编程实现了自动搜索非劣解群的目...
This study was undertaken to clarify the effects of root pruning on the organic constituents and early growth in each organ of seedling after transplanting, using 6 leaf aged seedlings without prunin...
This study was undertaken to find the effects of transplanting time and lodging time on palatability, protein content, amylose content and amylographic characteristics of milled rice in northern Kyus...
This study was carried out to examine the effects of planting density and planting patterns in reference to various characteristics at the panicle formation, heading and maturing stages in rice plants...
The effect of temporally high N application was investigated to develop the fertilization method that increases N content per leaf area (NCLA) without the increasing of specific leaf area. The change ...
A method of greening of nursling seedlings raised in nursery chamber, characteristics of these seedlings and transplanting accuracy to paddy field were investigated. Rice cultivar Sasanishiki seed was...
Phasic development of rice is influenced by various climatic conditions and the nursery duration. As a step toward the analysis of yield potential and yield loss in the Red River Delta, Vietnam, we co...
Rice nurseling seedlings were raised under temperature-controlled condition (32°C) in darkness or with illumination of 500lux (Exp.1) and 170lux (Exp.2) by fluorescent lamp for 1, 2 and 4 days before ...
Rice nurseling seedlings were raised under temperature-controlled condition (32°C) in darkness or with illumination of 500lux (Exp.1) and 170lux (Exp.2) by fluorescent lamp for 1, 2 and 4 days before...
To develop a new fertilizing system with a reduced amount of phosphatic fertilizer in sweet corn production, we applied potassium phosphate to the plug seedlings before transplanting to the field, and...
