于2016-2017年以花育25号为材料,在花生单作和间作条件下,设置施钙和不施钙处理,研究钙肥对单作花生、间作中间行和间作边行花生的植株性状、功能叶生育后期光合特性、糖代谢酶活性及产量的影响。结果表明,施用钙肥降低了花生主茎高和侧枝长,增加了花生分枝数、主茎节数,提高了叶片叶绿素含量、光合速率、蔗糖含量及蔗糖代谢相关酶活性;单作和间作花生荚果产量平均增产397.2 kg/hm~2,平均增产率19.9%。相同施钙水平下,越靠近玉米行的间作边行花生受遮荫影响越大,其主茎高、侧枝长较大,蔗糖合成酶(SS)、蔗糖磷酸合成酶(SPS)活性等生理指标低于单作花生。与单作不施钙比较,施钙显著增加了间作花生...

In 2016-2017, Huayu 25 was used as the material, which were treated by applying calcium and no calcium fertilizer, to study the effects of calcium fertilizer on the plant characteristics, photosynthetic characteristics, sugar metabolizing enzyme activity and yield of single-cropping, inter-cropping middle and side row peanut. The results showed that, application of calcium fertilizer reduced the height of main stem and the length of lateral branches, increased the number of branches and nodes of main stem, increased the chlorophyll content, photosynthetic rate, sucrose content and sucrose meta...
