摘要
试验以7年生温185核桃为材料,在雌花盛花期用不同浓度的GA3、6-BA和稀土微肥对核桃进行叶面喷施,研究了这3种生长调节剂对温185核桃座果率及叶绿素含量的影响。结果表明,除稀土微肥、GA3600 m g/L和6-BA 30 m g/L外,其余处理均能不同程度的提高核桃座果率,其中增幅最大的是6-BA 50m g/L,座果率比对照提高17.89%;各处理叶绿素含量均高于对照。
The object of this experiment is the walnut of Wen185 which is seven years old. Different concentrations of GA3,6-BA and rare element fertilizer were sprayed during full bloom stage of female flower. Effect of 3 kinds growth regulators on the fruit setting and chlorophyll content were studied. The results showed the treatmonts could enhance the fruit set percentage of walnut at different levels except for the rare element fertilizer,GA3 600 mg/L and 6-BA 30 mg/L. Among them the most increasing margin was 6- BA 50mg/L, which was 17.89% higher than comparison. The contents of the chlorophyll were all higher than the comparison.
