摘要:

为了探讨调环酸钙对小麦产量相关因素及安全性的影响,以小麦品种‘豫麦49’为材料,返青后施用不同剂量的5%调环酸钙EA开展田间试验。结果表明,小麦返青期施用5%调环酸钙EA 150~ 600 g/hm2,可矮化植株高度,降低基部节间长度、增加茎粗和茎壁厚度。调环酸钙能提高小麦穗数、穗粒数、千粒重和产量。返青期施用5%调环酸钙EA 300 g/hm2和5%调环酸钙EA 300 g/hm2+0.01%芸苔素内酯SL 150 mL/hm2的产量较高,分别达7410.0 kg/hm2和7560.0 kg/hm2,较对照(CK)分别增产10.7%和13.0%。5%调环酸钙EA对小麦安全无药害,建议在小麦上推广使用。

Abstract:

In order to explore the effect of prohexadione calcium (Pro-Ca) on the growth and yield factors and safety of wheat, taking wheat variety ‘Yumai 49’ as material, different doses of 5% Pro-Ca EA were applied to carry out field experiments after wheat turning green. The results showed that the application of 5% Pro-Ca EA (150-600 g/hm2) could dwarf plant height, reduce internode length, increase stem diameter and stem wall thickness. Pro-Ca could increase the number of ears, grains per ear, 1000-grain weight and yield of wheat. The application during the period of returning to green of 5% Pro-Ca EA 300 g/hm2 and 5% Pro-Ca EA 300 g/hm2 + 0.01% brassinolide SL150 mL/hm2 could achieve higher yield, reaching 7410.0 kg/hm2 and 7560.0 kg/hm2 respectively, increase by 10.7% and 13.0% compared with that of CK. 5% Pro-Ca EA is safe and harmless to wheat, so it is recommended to be popularized in wheat production.
