摘要： 小麦是中国重要的粮食作物之一，因全球气候变暖及耕作模式的改变，在小麦种植生产过程中面临着病、虫及草害频发的问题，其对小麦的产量和质量造成了重大威胁。植物生长调节剂作为具有控制植物生长、提高产量和品质的物质，在作物生产过程中已得到较为广泛的应用。但当前关于植物生长调节剂通过底施的方式在小麦生产上的应用研究相对较少。为了探究不同植物生长调节剂对小麦种子萌发、幼苗生长以及产量影响，采用底施的方法，研究甲哌鎓、氯化胆碱和胺鲜酯3种植物生长调节剂对小麦的影响。结果表明，3种供试植物生长调节剂在室内对小麦种子发芽势、发芽率提高均有显著促进效果(P≤0.05)，且对小麦幼苗的生长均有不同程度的促进效果。30 mg/L甲哌鎓、20 mg/L氯化胆碱、4 mg/L胺鲜酯可显著提高小麦株高、根系长度、茎叶鲜重以及根系鲜重。田间试验结果表明，以75 g (ai)/hm2甲哌鎓、30 g (ai)/hm2氯化胆碱、30 g (ai)/hm2胺鲜酯对小麦幼苗生长有显著的促进效果，小麦产量均有不同程度的提高。

Abstract:

Wheat is one of the important food crops. Due to global warming and changes in farming patterns, wheat planting and production processes are facing frequent diseases, insects and weeds damage, which pose a major threat to wheat yield and quality. Plant growth regulators, as substances that control plant growth and improve yield and quality, have been widely used in crop production. However, there are relatively few studies on the application of plant growth regulators in wheat production through basal application. To explore the effects of different plant growth regulators on wheat seed germination, seedling growth and yield, this study selected three plant growth regulators of mepiquat chloride, choline chloride and diethyl aminoethyl hexanoate, and used the basal application method to study their effects on wheat. The results showed that the three plant growth regulators had significant (P≤0.05) effects on the germination potential and germination rate of wheat seeds, and had different promotion effects on the growth of wheat seedlings. When wheat was treated with 30 mg/L mepiquat chloride, 20 mg/L choline chloride and 4 mg/L diethyl aminoethyl hexanoate, plant height, root length, stem and leaf fresh weight and root fresh weight were significantly increased. Meanwhile, in the field experiment, the results showed that the treatment of wheat with 75 g (ai)/hm2 mepiquat chloride, 30 g (ai)/hm2 choline chloride and 30 g (ai)/hm2 diethyl aminoethyl hexanoate had a significant effect on wheat seedlings, and the three plant growth regulators had different degrees of improvement on wheat yield.
