微生物菌剂和矮壮素组合处理对穴盘丝瓜幼苗徒长的抑制作用

目的]筛选适宜常熟地区穴盘丝瓜幼苗徒长的抑制方法,为集约化穴盘育苗提供理论和实践依据。方法]以春语微生物菌剂和不同浓度的矮壮素分别对连栋大棚日光温室内丝瓜育苗基质进行底水浇灌处理,研究不同处理对工厂化丝瓜幼苗徒长调控的作用。结果]播种前用稀释100倍的春语微生物菌剂和0.2 m L/L矮壮素溶液以浇透底水的方式处理的丝瓜幼苗壮苗效果最为显著,与对照相比,SPAD值显著增加,株高矮化显著,茎粗增加明显,根冠比和壮苗指数也显著升高。结论]在播种前用稀释100倍的春语微生物菌剂和0.2 m L/L矮壮素溶液浇透育苗基质的方法来控制丝瓜幼苗的徒长,达到壮苗的目的。

Effects of Combination of Microbial Agents and Chlormequat Chloride on Spindling of Gourd Seedlings

Objective] To select the moderate inhibition method of spindling of gourd seedlings in order to provide the theory basis and practice for intensive hole tray seedling.Method] The experiment was conducted by drenching the substrate with microbial agents of Chunyu and varied concentrations of chlormequat chloride before sowing to study the effects of different treatments on the spindling of gourd seedlings.Result] The gourd seedlings treated with microbial agents solution diluted 100 times and 0.2 mL/L chlormequat chloride showed good results in terms of the plant height, stem diameter, SPAD and ratio of root to shoot.Conclusion] Drenching the substrate with microbial agents solution diluted 100 times and 0.2 mL/L chlormequat chloride can avoid excessive seedling growth and cultivate strong seedlings.
