摘要
以樱桃番茄品种"冀东216"为试材,研究了不同时期喷施不同浓度膨大素对樱桃番茄生长发育的影响,以确定喷施的最佳时期及喷施浓度。结果表明:开花期喷施膨大素的效果显著好于坐果后喷施;经膨大素处理的番茄,生长速度、单果重、产量明显提高;可溶性固形物含量、坐果率、果穗附近的叶绿素含量及硬度也有不同程度的增大。以1 100倍液浓度的花期喷施膨大素对樱桃番茄的膨大效果最佳。
Cherry tomato variety ‘Jidong 216’ was used to study the impact on growth and development when applying CPPU on different growing stages and concentrations to determine the best stage and concentration of CPPU application.The results showed that better effect performed significantly when spray during flowering stage than after fruit set.Growth,unit weight and yield of tomato treated with CPPU were increased remarkably as well as soluble solid content,fruit setting rate,chlorophyll content near the ear and degree of hardness improved in different levels.It suggested that concentration of 1 100 times spraying during flowering stage achieved the optimum result for cherry tomato.
