Abstract:

The effects of increasing seeding rate on building Zoysia japonica turf by applying gypsum to improve alkaline soils were studied for the sake of the applying Zoysia japonica on alkaline soils．The results showed that the number of seedling(8058.5 seedling/m2), density(7511.2 adult/m2), height(46.2mm) and cover(92%) were 1.7,1.7,1.2 and 1.4 times as great as CK and markedly greater than CK , respectively, when the soils were improved by applying gypsum. The number of seedling（8058.5株/m2）and density(7511.2株/m2）were markedly increased and the established time advanced at least 7 days by increasing seeding rate after soil improvement.
