用 2种黑麦草在广州赛马会高尔夫球练习场的狗牙根草坪上进行了冬季盖播可行性试验。结果表明 ,冬季盖播黑麦草后 ,盖播处理区的狗牙根草坪同没有盖播的对照区草坪相比 ,绿期延长 ,同时其它坪用性状也明显提高 ,因而证明 ,在广州地区的狗牙根草坪上用黑麦草进行加绿盖播是完全可行而必要的。同时试验结果表明 ,草坪型黑麦草盖播草坪的坪用性状远远好于牧草型黑麦草的盖播处理。此外 ,合理的施肥和播量等因素也将直接影响盖播草坪的冬季坪用性状以及夏枯时狗牙根草坪的恢复生长。播量以 2 0 g/ m2 最为理想 ,可根据建植和管理水平酌情增减。生长前期以高施肥 (90 g/ m2 )为宜 ,夏枯前后的过渡阶段 ,以低施肥 (4 5g/ m2 )为佳。
Two kinds of ryegrass were tested on the winter sowing feasibility test on bermudagrass lawn at Guangzhou Jockey Club Golf Driving Range. The results showed that after the winter-covered ryegrass, the bermudagrass coverage in the covered area was longer than that in the control area without the cover-sowing, and the other pheasant cultivars were also significantly improved. Thus, it was proved that dogs in Guangzhou It is perfectly feasible and necessary to use a green grass cover on the lawn of the root. At the same time, the test results showed that the lawn-type rye grass-covered lawn was much better than that of the grass-type ryegrass. In addition, reasonable fertilization and sowing rate and other factors will also have a direct impact on winter sowing lawn plowing properties and bermudagrass regrowth growth. Seeding rate of 20 g / m2 is the most ideal, according to the establishment and management of the appropriate increase or decrease. In the early stage of growth, high fertilization (90 g / m2) is suitable, and the transitional stage before and after the summer fallow is better with lower fertilization (45g / m2).
