Abstract

Abstract:

To explore the effect of nitrogen rate on grain quality and nitrogen utilization of weak gluten wheat, wheat cultivar Ningmai13 and Wanximai0638 were adopted as test materials in the present study, and 4 nitrogen rates (N 0, 120, 180, 240 kg·hm^-2) were set. It was shown that with the increase of nitrogen rate from 0 to 240 kg·hm^-2, the grain yield of wheat first increased and then decreased, and the highest yield was achieved under nitrogen rate of 180 kg·hm^-2. When the nitrogen rate was 0-240 kg·hm^-2, with the increase of nitrogen rate, the protein content, wet gluten content, hardness, sedimentation value and stability time of grains showed upward trend. Nitrogen accumulated in plant and grains of weak gluten wheat mainly came from soil nitrogen both at flowering stage and maturity stages. With the increase of nitrogen rate from 120 kg·hm^-2 to 240 kg·hm^-2, the nitrogen accumulated from fertilizer in the grain increased first and then decreased, reaching the peak under nitrogen rate of 180 kg·hm^-2. When the nitrogen rate was 120-240 kg·hm^-2, the nitrogen use efficiency of weak gluten wheat was 25.68-44.76 kg·kg^-1, and the nitrogen fertilizer production efficiency was 25.16-50.82 kg·kg^-1. With nitrogen rate increased from 120 kg·hm^-2 to 240 kg·hm^-2, nitrogen fertilizer production efficiency of weak gluten wheat decreased.

Key words: weak gluten wheat, nitrogen rate, grain quality, nitrogen utilization
