基于Meta分析研究主要栽培措施对强筋小麦量质协同的调控
Effects of main cultivation practices on simultaneous improvement in grain yield and protein content of strong-gluten wheat:A Meta analysis
摘要
Abstract
The consumption of bread made from strong-gluten wheat is rapidly increasing in China,however,commercially available wheat grains of sufficient quality for bread making remain scarce in the domestic market.A high grain protein content(GPC)is desi-rable in strong-gluten wheat,but a decrease in grain yield(GY)is usually observed when achieving the targeted GPC in production.Sowing date,nitrogen application rate,and plant density are effective cultivation practices for regulating GY and GPC in strong-glu-ten wheat.In this study,a Meta analysis was performed on the effects of these main cultivation practices on the GY and GPG of strong-gluten wheat in the Huang-Huai-Hai Region using existing literature data from 2003 to 2023.The control(CK)was selected from October 10 to October 25 for sowing date,from 270 to 300 kg·hm-2 for nitrogen rate,and from 180×104 to 240× 104 plant·hm-2 for plant density,respectively.The Meta analysis showed that when the sowing date was delayed by 0-35 d,the GY of strong-gluten wheat was significantly reduced by 2.86％to 19.22％,and the highest drop occurred from a delay of 21-28 d.Moreover,GPC signi-ficantly decreased by 4.08％with a 0-7 day delay in sowing date,whereas a 21-28 day delay led to a significant increase of 10.54％.When the nitrogen application rate was reduced by 0 to 30 kg·hm-2,the GY was significantly increased by 4.67％;however,the GY was significantly decreased by 2.75％and 4.69％-36.84％when the nitrogen application rate was reduced by 30-60 and 90-300 kg·hm-2,respectively.Meanwhile,a reduction in nitrogen application rate from 30 to 300 kg·hm-2 resulted in an average decrease of 4.31％to 23.54％in GPC.When the plant density was increased by 0 to 90× 104 plant·hm-2,the GY was significantly improved by 1.73％—3.59％;and an average increase of 2.01％—2.61％was observed in the GPC,when the plant density was increased by 30×104 to 90×104 plant·hm-2.Furthermore,the relationship between GY and GPC of strong-gluten wheat was analyzed under different cultiva-tion practices mentioned above in this region.The qualified grain quality(GPC＞14.0％)while maintaining high yield(GY＞8 000 kg·hm-2)could be obtained with the sowing date ranged from October 10 to October 21,the nitrogen application rate ranged from 230 to 286 kg·hm-2,and the plant density ranged from 247×104 to 289×104 plant·hm-2.Correspondingly,the dry matter accumulation of strong-gluten wheat ranged from 14.7 to 17.0 t·hm-2 at flowering stage as well as from 20.4 to 26.6 t·hm-2 at maturity stage,while the nitrogen content of single stem,stems,leaf,and ear at flowering stage was maintained higher than 16.0,9.0,34.0 and 14.5 mg·g-1.These findings would provide novel approaches for the simultaneous improvement in the grain yield and quality of strong-gluten wheat for bread making in the Huang-Huai-Hai Region.关键词
