植物健壮素对辣椒农艺性状的影响

Effects of Strong and Healthy Promoter of Plant on Agronomic Characters of Pepper

[目的]为辣椒的长季节优质栽培提供理论依据。[方法]采用不同浓度植物健壮素(稀释500、750、1 000倍)对辣椒进行不同间隔时间(4、7、10 d)的处理,以清水处理为对照,研究不同处理对辣椒生长势、结果性、果实商品性和产量的影响。[结果]植物健壮素稀释1 000倍,间隔用药时间为7 d的处理可提高辣椒株高10.5%、茎粗8.5%和开展度10.2%,同时可提高辣椒的结果率(+17%),使辣椒商品率达95.0%,产量达17 976.0 kg/hm2,比对照高18.9%。[结论]植物健壮素对辣椒的最佳使用浓度为稀释1 000倍,最佳间隔用药时间为7 d。

[Objective] The aim was to provide the theoretical basis for long-seasonal high-quality cultivation of pepper.[Method] The peppers were treated by strong and healthy promoter of plant with different concn.（being diluted for 500,750 and 1 000 times） for different interval periods（4,7 and 10 d）,with the treatment by clear water as CK,the effects of different treatments on growth potential,fruiting characteristics,fruit commodity and yield of pepper were studied.[Result] When the strong and healthy promoter of plant was diluted for 1 000 times and the interval period of medication was 7 d,the plant height,stem thickness,expanding degree and fruiting rate of pepper were increased by 10.5%,8.5%,10.2% and 17% resp.;it made the commodity rate and yield of pepper reach 95.0% and 17 976.0 kg/hm2,its yield was increased by 18.9% in comparison with CK.[Conclusion] The optimum use concn.of strong and healthy promoter of plant was 1 000 times dilution and its optimum interval period was 7 d for pepper.
