Abstract

Abstract:

In order to explore the effects of nitrogen application on grain filling characteristics of winter wheat under drip irrigation at different panicle positions, Xindong22 and Xindong43 were used as test materials. The grain filling process of winter wheat was fitted by using Logistic equation under five nitrogen application amount (0, 150, 300, 450, 600 kg·hm^-2, denoted as N₀, N₁, N₂, N₃, N₄, respectively). It was shown that under drip irrigation, the grains in the central part of panicles showed advantages in weight. The grain filling parameters in the fast-increasing period and the slow-increasing period varied under different nitrogen application amount for different wheat cultivars. The optimal nitrogen application amount for Xindong22 and Xindong43 was 450 kg·hm^-2 and 300 kg·hm^-2, respectively. Under these treatments, the grain weight in the upper, middle and lower part of panicle was increased, and the duration of grain filling was extended, so that the yield potential could be realized.

Key words: nitrogen application amount, drip irrigation, winter wheat, grain filling characteristics
