- 摘要:
- 为促进光碳核肥的推广应用，以“爱莎”草莓为材料，设T1(施商品有机肥4 000 kg?667 m-2，氮磷钾复合肥30 kg?667 m-2)、T2（草莓生长过程中喷施6次光碳核肥）、T3（施商品有机肥3 000 kg?667 m-2，草莓生长过程中喷施50%T2用量的光碳核肥）、CK（不施肥，喷施清水），调查不同处理下草莓株高、茎粗、叶面积、叶片SPAD、光合作用及产量情况。结果表明：在T3处理条件下，草莓株高茎粗均高于其他处理，其次为T2处理。T3和T2处理的净光合速率均显著高于对照。T3处理的气孔导度最大。T2处理的胞间CO2浓度和气孔蒸腾速率最大。T3处理的叶面积和SPAD值最高，产量也最高。可见光碳核肥和有机肥配施效果最好，可显著提高植株的株高、茎粗和产量等。
