氮素 水稻 Nipponbare OM052 氮肥利用率
2023/2/27
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。
The Candidate Genes Underlying a Stably Expressed QTL for Low Temperature Germinability in Rice (Oryza sativa L.)
Rice Low temperature germinability Quantitative trait locus Candidate gene Genomewide association study
2023/4/21
Background: Direct seeding is an efficient cultivation technique in rice. However, poor low temperature germinability (LTG) of modern rice cultivars limits its application. Identifying the genes assoc...
Physiological and genome-wide gene expression analyses of cold-induced leaf rolling at the seedling stage in rice (Oryza sativa L.)☆
Rice (Oryza sativa L.) Cold-induced leaf yellowing Cold-induced leaf rolling Physiological analysis
2023/4/21
Leaf rolling and discoloration are two chilling-injury symptoms that are widely used as indicators for the evaluation of cold tolerance at the seedling stage in rice. However, the difference in cold-r...
【目的】 水稻生长模型是实现水稻管理自动化的重要工具。现有水稻模型未充分体现水稻生长的“移栽时间效应”，模型参数较多，使用较复杂。基于这些问题改进和完善水稻生长模型，以提高模型的准确性和实用性。 【方法】 在ORYZA与RCSODS模型的基础上，结合已有水稻生育期时间节点计算方法及其对干物质积累与分配的影响权重，在模型中增加移栽时间效应和水稻动态消光系数方程。利用2003—2012年黑龙江省...
