摘　　要：为探究基于Priva系统控制下的微型月季在生产中最佳施氮量及光合生理特性,以小红帽(Massland)微型月季品种为对象,采用单因素随机区组方式,设置5个氮素水平,施纯氮梯度量为0(对照)、1.5、2.5、3.5、4.5 g/株,分别记为N1、N2、N3、N4、N5。在微型月季盛花期测定其株高、茎粗、地上部干物质、光合参数和荧光参数。结果表明:随着施氮量的增加各指标呈现先增加后降低的趋势,N1的各指标数值低,N3、N4的各指标数值高。该试验条件下微型月季最佳生长发育的施氮量为2.5~3.5 g/株。In order to explore the optimal amount of nitrogen and photosynthetic physiology in the production of the intelligent greenhouse microlunar season,the small red hat(massland)micromonthly variety is the object,and the five nitrogen levels are set by the method of single factor random area.The degree of pure nitrogen gradient is 0(ck),1.5,2.5,3.5,4.5 g/plant.In the microlunar season,the high,stem,dry material,photosynthetic parameters and fluorescent parameters were measured.The results showed that with the increase of nitrogen quantity,the trend of the decrease of these indicators was lower,and the different index phenotype was better.The optimum growth and development of the miniature rose in the experimental condition was 2.5~3.5 g/plant.
