摘要
为探索生产中常用的生长调节剂及微肥在富士苹果树上的应用效果,该研究以盛果期6a生富士苹果树为试材,通过叶面喷施的方法,进行了GGR6号、ABT4号、喷施宝、必多收4种生长调节物质的应用对比试验。研究结果表明:4种物质均可促进苹果树新梢生长,增大叶面积,提高叶的质量,提高苹果坐果率和单株产量,改善果实品质,提高果型指数、单果重以及含糖量。但4种物质作用效果差异显著,以GGR6号最好,其次为ABT4号,两者之间无显著差异,均可应用于富士苹果的生产。
In order to explore the application effect of growth regulators and micronutrient fertilizers in Fuji apple trees,the comparative experiments of GGR6,ABT4,Penshibao and Biduoshou were carried out by foliar spraying on Fuji apple trees at full fruit stage.The results showed that all the four substances could promote the growth of new shoots.The leaf area,leaf quality,fruit setting rate,fruit quality,fruit type index,fruit content,sugar content and yield per plant were all improved.However,the effects of four substances were significantly different,GGR6 was the best,followed by ABT4.There was no significant difference between the two substances,and they could be used in Fuji apple production.
