噻苯隆粉剂—太丰宝对“红富士”苹果品质的影响研究

Effects of Thidiazuron WP-Taifengbao on Quality of Fuji Apple

以"红富士"苹果为试验材料,在其盛花期和幼果期进行噻苯隆粉剂—太丰宝喷布试验。结果表明:噻苯隆粉剂—太丰宝喷布"红富士"苹果可有效促进苹果果实纵向生长,改变果实果型指数,提高果实的高桩率,增加苹果单果重,提高苹果产量;随着噻苯隆粉剂—太丰宝喷布浓度的逐渐增加,果实果型指数、单果重逐渐增加,可溶性固形物含量逐渐降低,硬度、可滴定酸含量与对照无明显差异。

An experiment was done by spraying Thidiazuron WP-Taifengbao upon the Fuji apple trees in the phase of the florescence time and young fruit time. The results showed that spraying the Fuji apple trees with Thidiazuron WP-Taifengbao could promote the vertical growth of the apple fruits, change the fruit shape index, improve the rate of high-pile fruits, in-crease the apple fruit weight and improve the yield of the apple. Along with gradual increase of the spray concentration of Thidiazuron WP-Taifengbao, the fruit shape index and single fruit weight increased gradually, the soluble solids content de-creased gradually and there were no significant differences in the index of hardness and titratable acid content.
