施氮量对漯麦36光合特性、品质和产量性状的影响
Effects of Nitrogen Application Rate on Photosynthetic Characteristics,Quality,and Yield Character of Lu-omai 36
摘要
Abstract
In order to clarify the optimal nitrogen application level of medium strong gluten wheat in central Henan Province,the medi-um strong gluten wheat variety Luomai 36 was used as material,five nitrogen application levels included 0 kg·hm-2(N0),90 kg·hm-2(N1),180 kg·hm-2(N2),270 kg·hm-2(N3)and 360 kg·hm-2(N4)were set up,photosynthetic characteristics,quality,nitrate reductase activity,free amino acid content and yield character were measured under different nitrogen application levels.The results showed that the SPAD content and photosynthetic parameters of wheat flag leaves increased first and then decreased from the anthesis stage to after anthesis stage with the increased nitrogen application rate.The processing quality was positively correlated with the nitrogen ap-plication rate in the reasonable nitrogen application range.Water absorption,tensile area,tensile resistance,formation time,stability time,wet gluten content and settlement value of Luomai 36 increased first and then decreased with the increased nitrogen application rate,which were the highest under N3 treatment,and decreased with the increased nitrogen application rate was N4.The yield of Luo-mai 36 under N3 treatment was significantly different from that under N0 treatment with the increasing application of nitrogenous fer-tilizer.In conclusion,nitrogen application could improve the photosynthetic characteristics of flag leaves of medium-strong gluten wheat,and then increase the yield and effectively improve the processing quality in reasonable nitrogen application range.Under the experimental conditions,the photosynthetic parameters,quality and yield of Luomai 36 are better under the nitrogen application rate of 270 kg·hm-2,which is used as the best nitrogen application rate for medium strong gluten wheat cultivation in central Henan Province.关键词
