有机肥替代部分化肥氮对特色小麦干物质积累、产量及品质的影响
Effect of Replacing Nitrogen Fertilizers with Organic Fertilizers on Dry Matter Accumulation,Yield and Quality of Colored Wheat
摘要
Abstract
To improve the yield and quality of colored wheat in southwest Shandong,this study explored the effects of different proportions of organic fertilizer instead of chemical fertilizer nitrogen on dry matter accumulation,yield and quality of colored wheat,aiming to clarify the optimal fertilization scheme for colored wheat in this area.A field experiment was conducted from 2022 to 2023,to systematically study the effects of no fertilizer(CK),single chemical fertilizer(CF),25%(M25),50%(M50)and 75%(M75)organic fertilizer replacing nitrogen fertilizer on dry matter accumulation,grain yield,quality of two colored wheat varieties(A1'Shannongzimai 1'and A2'Jilanmai 1').The results showed that compared with CK treatment,different fertilization treatments could increase grain yield,quality and the dry matter accumulation of wheat at wintering,regreening,flag-picking and maturity stages to varying degrees.In term of dry matter accumulation at the maturity stage,there was no significant difference between organic fertilizer and CF in A1 cultivars,and M25 was the highest;compared with CF,both M25 and M50 were much higher in A2 variety,and there was no significant difference with M75.The variation law of grain yield of the two varieties under different fertilization treatments was basically the same,with the increase of the proportion of organic fertilizer replacing chemical fertilizer,grain yield were gradually decreased.Compared with CF,M25 and M50 treatments could increase the grain yield,with a range of 1.01%to 3.76%for variety A1 and 3.48%to 5.0%for variety A2.M75 treatment reduced grain yield.In M25 treatment,the crude protein content of the two varieties increased by 3.14%and 1.81%,the content of wet gluten increased by 1.70%and 2.46%;the ductility increased by 1.10%and 0.79%,respectively.With the increase of organic fertilizer replacing nitrogen fertilizer,the crude protein content and wet gluten content decreased,volume weight and the ductility of A2 variety were no significant difference.In summary,M25 treatment could effectively improve grain yield,quality of colored wheat in the wheat planting area of southwest Shandong.关键词
