Experiment On Filter And Application Of Grass Which Is The Breed Of Cold Season In Harbin

With the rapid development of our country economy building, the scientific resquest on plant building up landscape continuously has increased during the ecology gardens cities building for recent years. The method of study on the plant building up landscape has alse been thought much from the point of application and spreading. The paper selected eleven varieties grassplot prematurity standing graim with prematurity (Midnight, Nassall, Eclipse, Liberty, Nustar,Galade,Park, Alene, Huntsville, Conni, Nimbus) as research object. We carried out detailed observe and study on mostly properties (texture, density, colour, surgrind) and applicability (live through the winter and the summer.redisease) and growing rate after building up grassplot in the substance season period (regreen period, scorch period, viridity period). And we carried out all-side quality estimate on eleven varieties through NTEP appraise system. Then did amount change and exacter estimation about them with the environment adaption parameter and use of grassplot parameter and number statistic analysis method. Among them, the higher grade varieties for environment adaption parameter are : Midnight, Nassall, Eclipse, Conni., and the higher grade varieties for use of grass parameter are : Midnight, Nassall, Eclipse, Huntsville, Conni, Nimbus. On the base of the statistic analysis, shearing height in different varieties have made certain through different shearing height for different variety grass comparing criterion margin and difference quotieth value. Accordingly best varieties selected in accord with Harbin's climate and entironment condition are Conni, Midnight, Huntsville,, Nassall, Nimbus, Eclipse . Moreover, we analyzed the individual difference among the other varieties and different scientific basis for application and building up landscape with law grass's new variety in Harbin City. At the same time, we analyzed and discussed as a whole the application of the lawn plant in the garden. We expatiated the function and effect of the lawn plant in garden plant building up landscape and brought forward scientific and reasonable ordonnance mode. Consequently, theoretics basis reasonable was provided for lawn plant in practice application.
