摘要: 中国红壤地区季节性干旱非常严重，土壤水分条件是制约该地区作物和果树生长发育的主要环境因子之一。以宫川温州蜜柑Citrus unshiu ‘Miyagawa Wase’盆栽幼树为材料，于2003－2004年春季利用土壤水分探头（FDR）测定红壤水分，研究了红壤相对含水量对春季柑橘叶长、叶宽和叶梢长的影响，并比较了不同红壤相对含水量处理下柑橘叶片与根系对氮磷钾的累积。结果表明，橘叶面积、叶周长、叶宽值均在75%时达最大值，为12.25 cm2，13.84 cm，3.19 cm。适当缺水有利于橘叶中氮的积累。叶与根系对氮的累积差异不大，但叶磷钾的累积量远低于根系的。橘叶中磷与红壤相对含水量呈显著正相关（R2=0.944 3*，P0.05），而各红壤相对含水量处理间橘叶中钾无差异。当红壤相对含水量≤30%。钙镁铁的积累受到了显著抑制。综合橘叶生长及对营养元素的吸收情况，红壤相对含水量在75%左右，最适柑橘叶片的生长。表3参14

Abstract: Red soil moisture makes an important role in the production of crop and fruit as one of the most limiting factors in the red soil region of China. Citrus is the main fruit in the region. The objective of this study was to explore the effects of red soil relative water content （RSWC） on leaves growth and nutrient accumulation of citrus in spring，further，to provide the theoretical foundation for economic irrigation of citrus production in red soil region of China. Mature satsuma mandarin trees（Citrus unshiu ‘Miyagawa Wase’） were selected as experimental materials and Frequency Domain Reflectometry（FDR） was used to monitor red soil moisture. And there were five red soil moisture treatments，which red soil water content accounted on 30%，45%，60%，75% and 90% of the maximum for water content in red soil field. The results showed that the leaf growth factors including the leaves area，the leaves perimeter and the leaves width all reached the maximum values，which were 12.25 cm2，13.84 cm and 3.19 cm，respectively，When RSWC was 75%.As for nutrition accumulation，soil moisture was advantageous to N accumulation when soil water stress was the right amount. P was positively and significantly（R2 = 0.944 3，P＜0.05） correlated with RSWC while no differences for K in leaves was found. When RSWC was below 30%，accumulations of calcium （Ca），magnesium （Mg），and iron （Fe） were negatively affected. In addition，there were no differences for N in between leaves and roots；however，P and K in leaves were less than in roots. Overall balance of leaves growth and nutrient accumulation，it was more beneficial for leaves growth when RSWC was about 75%. ［Ch，3 tab. 14 ref.］
