摘要: 利用CERESRice模型开展宁夏河套灌区水稻低温冷害影响定量化评估,需要确定河套灌区主栽水稻品种的遗传参数。采用1996-2013年中卫、永宁国家一级农业气象试验站水稻试验观测资料,结合同期气象和稻田土壤属性数据,对河套灌区宁粳28号(晚稻)、富源4号(中稻)、宁粳16号(晚稻)3个主栽水稻品种进行遗传参数调试,并以水稻开花期、成熟期、籽粒产量、地上部生物量和最大叶面积指数进行误差验证。结果表明:中稻富源4号遗传参数调试效果最好,开花期、成熟期和产量一致性指标分别为0.86、0.77和0.84;晚稻宁粳16号遗传参数调试效果较好,开花期、成熟期和产量一致性指标分别为0.86、0.64和0.91;晚稻宁粳28号开花期、成熟期和产量的一致性指标分别0.58、0.77和0.92;对成熟期、地上部生物量和最大叶面积指数模拟效果一般,对开花期和产量模拟效果较好。表明主栽水稻品种遗传参数调试总体效果较好,3个主栽品种遗传参数适于河套灌区水稻生长发育,可用于低温冷害对水稻影响的定量化评估模拟研究。

Abstract: In order to estimate the impact of chilling damage to rice with the CERESRice model, the main rice genetic parameters in Hetao irrigation area must be determined. Based on observed data during 1966-2013 from national agrometeorological experimental station in Zhongwei and Yongning, combined with the weather and attribute of soils at the same period, the genetic parameters were debugged. The days of anthesis and maturity, rice yield, aboveground biomass weight at maturity, maximum leaf area index were used to verify the error between measured and simulated value of three main rice varieties (Ningjing28, Fuyuan4 and Ningjing16). The results showed that the genetic parameter for midseason rice Fuyuan4 had the best performance, and the D index of anthesis, maturity and yield was 0.86, 0.77 and 0.84, respectively. The genetic parameter for late rice Ningjing16 had better performance, and the D index of anthesis, maturity and yield was 0.86, 0.64 and 0.91, respectively. The genetic parameter for late rice Ningjing28 had good performance, the D index of anthesis, maturity and yield was 0.58, 0.77 and 0.92, respectively. The three main variety genetic parameters could be applied to simulate the rice growth in Hetao irrigation region, and used for rice chilling damages simulation study further .
