硼肥不同施用方式对法国青刀豆生长与产量的影响

目的]探讨硼肥不同施用方式对法国青刀豆生长与产量的影响,为实际生产提供指导。方法]通过土壤基施、叶面喷施、土壤基施与叶面喷施相结合,对不同处理植株的生长势与产量进行了测定与比较分析。结果]硼肥3种不同施用方式都能增强植株的生长势,增加单株粒数、千粒重和经济产量,以土壤基施与叶面喷施相结合的处理效果最好,其次为叶面喷施。结论]土壤基施与叶面喷施相结合的效果好于单独叶面喷施或土壤基施,但并非后两者效果的简单加和。

Effects of Different Application Method of Boron Fertilizer on Growth and Production of French Bean

Objective]Effects of different application method of boron fertilizer on growth and production of French bean were studied to provide guidance for real production.Method]Growth vigor and yield of plants treated by basal application,foliage spraying,combination of basal application and foliage spraying with boron fertilizer were determined and compared.Result]All the three different application methods of boron fertilizer could enhance growth vigor,increase number of seeds per plant,1 000-grain weight and economic yield.Effect of combination of basal application and foliage spraying was the best,followed by foliage spraying.Conclusion]Effect of combination of basal application and foliage spraying was better than that of foliage spraying or basal application only,but it was not simply the sum of effects of the latter two treatments.
