摘　　要：本研究旨在探究叶面喷施外源硒钙制剂(氨基多糖硒钙水溶肥)对优质食味粳稻产量、品质和营养强化的影响。以优质食味粳稻南粳9108、南粳46、南粳2728、南粳505、淮稻5号和徐稻9号为研究材料,设置田间试验,在破口期喷施133 ml/L氨基多糖硒钙水溶肥(T),以喷施等量清水为对照(CK),成熟期测定水稻的产量及其构成因素、品质(外观品质、加工品质、营养品质、食味值)以及稻米中硒和钙的含量。方差分析结果表明,氨基多糖硒钙水溶肥可显著提高水稻每穗粒数和产量,平均增幅分别为10.01%和7.10%;对有的供试品种能改善粒型,提高整精米率,降低不完善粒率和黄米粒率;处理后垩白粒率和垩白度下降,平均降幅分别为23.03%和18.52%;米饭食味值显著提高,平均增幅为6.53%。此外,氨基多糖硒钙水溶肥处理对稻米中硒、钙具有营养强化的作用,大米中硒、钙含量平均增幅分别为357.01%和86.82%。显然,氨基多糖硒钙水溶肥对水稻产量、品质以及稻米中硒、钙营养强化具有良好的效果,具有一定的推广价值。本研究结果可以为水稻稻米中的硒、钙营养强化栽培提供理论和实践依据。To investigate the effects of amino polysaccharide selenium-calcium water-soluble fertilizer on the yield,quality and nutritional enhancement of high-quality edible japonica rice,a field experiment was conducted with high-quality japonica rice Nanjing 9108,Nanjing 46,Nanjing 2728,Nanjing 505,Huaidao 5 and Xudao 9 as research materials.The amino polysaccharide selenium-calcium water-soluble fertilizer(T)was sprayed at the break period with 133 ml/L,and the same amount of water was used as the control(CK).The yield and its components,quality(appearance quality,processing quality,nutritional quality and taste value),and the contents of selenium and calcium in rice were determined at maturity stage.The results showed that the amino polysaccharide selenium-calcium water-soluble fertilizer could significantly increase the number of grains per spike and yield,with an average increase of 10.01%and 7.10%,respectively,it also improved the grain shape,increased the rate of polished rice,and significantly increased the taste value with an average increase of 6.53%.However,the chalky rice rate and degree of chalkiness decreased,with an average decrease of 23.03%and 18.52%,respectively.Besides,the rate of imperfect grain and yellow rice reduced.Furthermore,the amino polysaccharide selenium-calcium water-soluble fertilizer could significantly increase the contents of selenium and calcium in rice,with an average increase of 357.01%and 86.82%,respectively.Obviously,the amino polysaccharide selenium-calcium water-soluble fertilizer has remarkable effects on regulating rice yield,quality,selenium content and calcium content,so it has certain promotion value.The results of this study can provide theoretical and practical basis for rice nutrition intensification cultivation.
