Effects of 0.1%triacontanol microemulsion on the inflorescences fruit setting rate,yield and quality of apple tree
Red Fuji apple is used as the test material,apple trees are sprayed by the foliar spraying method using 0.1%triacontanol microemulsion at dilutions of 2 000 times,1 500 times,1 000 times and 750 times respectively,0.001 6%28-epibrassinolide aqueous solution at 1 000 times dilution,and a blank control.The effects of different treatments on the inflorescence fruit setting rate,single fruit weight,yield and quality of apple tree are compared.The results show that 0.1%triacontanol microemulsion can significantly improve the inflorescence fruit setting rate,fruit shape index and yield of apple trees,while having a relatively small impact on fruit quality.Among them,the 0.1%triacontanol microemulsion with a 1 000 fold solution(S3)has the best effect,increasing yield by more than 15%for two consecutive years.The research results can provide a basis for using 0.1%triacontanol microemulsion in production to promote apple quality and yield.
