全周期间作模式胶园内间作生姜的生长及抗性生理特征

研究南北行向的全周期间作模式胶园宽行间间作生姜的生长及其抗逆生理变化。结果表明：在宽行中间12 m宽的区域内，不同位置间作的生姜产量间存在一定差异，以宽行东侧约3 m宽区域的生姜株高、茎粗和叶片SPAD值表现最好，产量最高，其次为西侧区域，在宽行中间6 m宽的区域则不适宜生姜生长；不同位置间作生姜叶片的游离脯氨酸(Pro)含量、丙二醛(MDA)含量、超氧化物歧化酶(SOD)和过氧化物酶(POD)活性总体上无显著性变化(P＞0.05)。综上所述，在全周期间作模式胶园宽行中靠近橡胶树的两侧较适宜生姜种植(特别是东侧)，不同位置间作对生姜抗逆生理的影响不大。

Characteristics of Growth and Physiology of Stress Tolerance of Ginger Intercropped in Rubber Plantation with Paired Row Planting System

Growth and physiology of stress tolerance of ginger intercropped in the wide row of south-west oriented rubber plantation with paired row planting system were investigated in this paper. Results showed that, in the 12-m width area in the wide row, there was significant difference of yield of ginger between different sites. Hight, stem thickness and SPAD of ginger grown in the east 3-m width area performed best. Highest ginger yield also was recorded in this area, followed by the yield of ginger planted in the opposite area. Ginger was not suitable to planted in the middle 6-m with area. Totally, content of Pro and MDA and activity of SOD and POD in different sites of ginger were not significantly different (P>0.05). Conclusively, ginger could be planted in the area where was close to rubber tree, especially in the east. Performance of physiology of stress tolerance of intercropped ginger didn't differ in each site.
