摘要/Abstract

摘要： 本研究以9个‘津农香’水稻新品系及两个主栽品种为试验材料,在大田设置高、中、低3个栽培密度,检测不同种植密度下各品系在关键生育时期生理指标的变化,分析品系间的差异并考察各品系的产量及其构成因素的变化。结果表明：（1）在产量构成方面,随着种植密度的增加,株高呈逐渐增加的趋势;最大穗长出现在中密度条件下;虽然高密度和中密度下的产量差异不显著,但中、高密度下的产量均高于低密度时的产量;结实率和千粒重对产量具有显著影响;（2）生理指标方面,SOD和POD的酶活性均呈现先上升后下降的趋势,并在中密度下最高;CAT酶活性在中密度下最低,且呈现出先下降后上升的趋势。综合分析可知,中密度的种植条件更适合‘津农香’粳稻新品系。

Abstract: This study used nine new varieties of ‘Jinnongxiang’ rice and two main cultivated varieties as experimental materials, which were planted in the field. Three planting densities were set, namely high density（row spacing 30 cm, plant spacing 12 cm）, medium density（row spacing 30 cm, plant spacing 16 cm）, and low density（row spacing 30 cm, plant spacing 20 cm）. The changes in physiological indicators of each variety at key growth stages under different planting densities were detected. The differences among varieties were analyzed, and the changes in yield and its components of each variety were investigated. The results showed that:（1）In terms of yield components, plant height gradually increased with the increase of planting density; the longest panicle length occurred under medium density; the yields of medium and high densities were higher than that of low density, but there was no significant difference between high and medium densities; the seed setting rate and 1000-grain weight had a significant impact on yield;（2）In terms of physiological indicators, the activities of SOD and POD enzymes showed an increasing trend first and then a decreasing trend, and reached the highest level under medium density; the activity of CAT enzyme was the lowest under medium density and showed a decreasing trend first and then an increasing trend. Comprehensive analysis indicates that the medium density planting condition is more suitable for the new ‘Jinnongxiang’ japonica rice varieties.
