Nutrient use efficiency (NuUE), comprising nutrient uptake and utilization efficiency, is regarded as one of the most important factors for wheat yield. In the present study, six morphological, nine nutrient content and nine nutrient utilization efficiency traits were investigated at the seedling stage using a set of recombinant inbred lines (RILs), under(More)
Potassium (K) is one of the most important mineral nutrients limiting plant growth in agricultural systems. This study investigated the effects of low-K treatments and detected quantitative trait loci (QTLs) for K efficiency traits at the seedling and adult stages of wheat. Eleven seedling traits under a hydroponic culture trial with five K treatments and(More)
Compared to the traditional laboratorial measure method, the spectroscopy method is more excellent and non-destructive to measure the content of chlorophyll. The aim of the paper was to determine the contents of chlorophyll in winter wheat by reflective spectroscopy. Pretreatment method of orthogonal signal correction (OSC) was used to reject uncorrelated(More)
In this paper, a 5V 8b 40Msamples/s pipelined A/D converter is presented. The A/D converter contains seven stages and each stage realizes a resolution of 1.5bit. To reduce both linear and nonlinear errors, bottom-plate sampling, bootstrap and digital correction techniques are applied in ADC design. Accurate clocks are necessary for those techniques.(More)
A study on the design and fabrication of a three-paired-electrodes voltage controlled capacitor (VCC) with complex membrane on a high-resistivity silicon substrate is reported. The complex membrane is composed of 0.8 micron Al and 0.15 micron SiON realized using sputtering and the PECVD process. The suspended membrane structure is obtained with polyimide as(More)
