氮素是植物生长发育所需的大量元素之一,水稻是我国的主要粮食作物,水稻生产对氮的需求仅次于水,是构成水稻生长成本的主要部分。目前,水稻氮肥表观利用率只有39%,即施氮肥量的50%以上残留在环境中。因此,在保证产量不减的基础上如何提高氮肥的利用效率,减少氮肥的使用量是我国农业可持续发展亟待解决的重要问题。
To understand the genetic basis of nitrogen and phosphorus uptake in the cultivated rice, quantitative trait loci (QTL) analysis for 7 nitrogen and phosphorus uptake-related traits including above-gro...
Vehicular communication (V2X) technologies are expected to be common in the future, providing better transportation safety and efficiency. However, their large-scale deployment requires addressing som...
The objectives of this study were to estimate linkage disequilibrium (LD), describe and scan a haplotype block for the presence of genes that may affect milk production traits in Portuguese Holstein ...
The research was focused on operational measurements of tractor plough tools and their subsequent utilisation and simulation under laboratory conditions by a hydrostatic simulator. In this field, th...
This paper presents recent improvements of the CampusGIS of the University of Cologne (http://www.campusgis.de) which is designed, developed and established by the GIS & Remote Sensing research group ...
The Root Zone Water Quality Model (RZWQM) is a one-dimensional, lumped field-scale model. It can simulate major physical, chemical, and biological processes in an agricultural crop production system. ...
Genes that are expressed in skeletal muscles may play a role in prenatal muscle development and postnatal muscle growth and can be considered candidates for economically important traits. Four porcine...
Geometric performance parameters of three-point hitch system of a most sold model of a 2-wheel drive Indian tractor were determined by generating the path of upper and lower hitch points by kinematic ...
The efficiency of genome-wide association analysis (GWAS) depends on power of detection for quantitative trait loci (QTL) and precision for QTL mapping. In this study, three different strategies for G...
Population-based linkage analysis is a new method for analysing genomewide single nucleotide polymorphism (SNP) genotype data in case–control samples, which does not assume a common disease, common va...
Stand growth and yield models include whole-stand models, individual-tree models and diameter-distribution models. In this study, the three models were linked by forecast combination and parameter rec...
The Root Zone Water Quality Model (RZWQM) is a one-dimensional, lumped field-scale model. It can simulate major physical, chemical, and biological processes in an agricultural crop production system. ...
Permit me first to bring you felicitations from theAfrican Development Bank, particularly from our Chief Economist & Vice President, Prof. Mthuli Ncube, who I am representing.
