为缓解绿篱修剪压力,节减经费,进行了施用多效唑对绿篱新梢影响的试验研究.认为施用不同浓度多效唑,对绿篱新梢生长均有影响,其中2000mg/L浓度效果最佳。喷叶或根施一个月后,新梢有明显变化,叶片色深绿,抑制生长,可减少或不修剪。方法简便、易行,比修剪每100m2节省人工费10元左右. 相似文献

This paper presents results from a survey of border hedges on farmland in western Kenya. The survey covered 160000 ha of high
potential land in eastern Siaya District and Vihiga District of western Kenya. The survey attempted to widen the knowledge
of the typology, the biomass and the parameters influencing the spatial distribution of hedge types. Spatial analysis was
used to delimit hedge type sub-regions (using cluster analysis) and to identify the variables influencing the spatial distribution
of hedge types (using discriminant analysis). It is demonstrated that a complex association of variables is influencing the
subdivision of the two districts in hedge type sub-regions in which ethnicity, population density, area in woodlots and ecological
variables like elevation, rainfall and soil fertility are important variables. These variables are influencing each other
and are responsible for the contrasting situation in Vihiga and Siaya District. Border hedges have similar functions in both
districts (demarcation of land, to prevent cattle from entering), nevertheless species composition and dimensions differ remarkably
in both districts. Border hedges in Siaya District are poorly managed or not managed at all. In Vihiga District people are
used to manage their hedges. Agroforestry techniques, for example techniques based on frequent pruning of border hedges, have
a high chance in being successful in this district because no additional investment in labour or time is required. The spatial
distribution in the amount of biomass is strongly correlated with the distribution in the per cent area ground cover of border
hedges. This means that secondary data on the area in hedges derived from aerial photographs can serve as a useful indicator
of the biomass present. As a result, the most difficult part of the field survey, the destructive sampling for the determination
of the biomass, can be eliminated, making general surveys considerably easier.
