矿质营养对稻米品质影响的研究进展

Progress of Effect of Mineral Nutrition on Paddy Rice Quality

矿质营养对水稻产量和稻米品质的形成有重要影响,调控全生育期施肥量和各生育期施肥比例是施肥技术的两个方面。不同类型的矿质营养在稻米品质形成过程中所起的作用不同,且各种矿质元素间存在一定程度的互作效应,不仅如此,矿质营养对稻米品质的影响还存在品种间、品质指标(特性)间的差异。因此,在优质米生产中,针对某一主栽品种,应全面考虑肥料类型、施肥量、前后生育期施肥比例及不同品质指标间的协调关系,制定施肥方案,以提高稻米的综合品质。

The mineral nutrition has important the fertilizer application proportion during the influence to yield and quality; of the paddy rice. Regulate entire growth period and varies growing priods are two aspects of fertilizer application technique. Different type mineral nutriation plays different role in the paddy rice quality forming process and each kind of mineral substance element has a certain degree interaction. Moreover, its differences to the paddy rice quality also exsists among different varieties and the quality indexes. Therefore, kinds of fertilizers, application quantity, the prorportion and the harmonious relationship between quality indexes should be considered comprehensively. And then established suitable scheme to enhance the synthetical quality of paddy rice.
