Abstract
[Objective]The paper aimed to study effects of Nitrogen rate on the growth and turf quality of wild cultivars " Handan " bermudagrass selected by Agricultural University of Hebei which expected to provided theoretical basis and technical guidance for popularization and application of this variety in middle and south Hebei Province. [Method] Test designed at random, amount of nitrogen fertilizer designed as high "N2 9 g/m2 ",middle "N2 6 g/m2 "and low "N2 3 g/m2"and control of 4 treatments, 3 times repeat, total 12 area of 1 m2. Amount of nitrogen fertilizer of all the area were: P2O5 4 g/m2 and K2O 4 g/m2. In the growth season of bermudagrass ( May-October ), 22th of every month were fertilized, 6 times a year. mowing height of turf was 4 cm and mowing frequency depended on the growth speed, adequate irrigation in order to keep no-drought stress. Turf quality score were followed by international NTEP 9 scores standard, clipping yields were measured by drying method. [Result] The results showed that bermudagrass cultivated in North China, regarding the middle-high quality bermudagrass, middle nitrogen treatment had the better effects. [Conclusion] Nitrogen fertilizer can effectively enhance color and density, improve turf quality, prolonged the green period of bermudagrass turf; Clipping yield increased significantly with nitrogen applied rate increased.关键词
