Abstract
Abstract: The experiment was conducted by using four high quality late rice varieties, including Taiyou 398, Huanghuazhan, Tianyouhuazhan, and Meixiangxinzhan under four nitrogen treatments of 0, 135, 180, and 255 kg hm–2 to select the optimum nitrogen application rate for the coordination of high quality and high yield. The appropriate increase of nitrogen application improved the yield of high quality rice, which reached maximum under the nitrogen treatment of 180 kg hm–2. When the nitrogen application was 180 kg hm–2, the indicators such as the brown rice rate, milled rice rate and head milled rice rate for all varieties reached maximum except for the head milled rice rate of Huanghuazhan. As more nitrogen was gradually applied, there were growing length-width ratio, protein content and gel consistency of double-season high-quality late rice while in contrast reduction in chalky grain percentage, chalkiness degree and amylose content, which also brought about a steady drop in peak viscosity, trough viscosity, breakdown, final viscosity while a rise in setback and pasting temperature. To sum up, the appropriate increase of nitrogen application can improve the processing quality, appearance quality, cooking and nutritional quality while deteriorate the RVA characteristics. The nitrogen application of 180 kg hm–2 facilitates a better coordination between quality and yield in high quality double-season late rice under mechanical transplanting.
