为了探讨“调节膦”在抑制园林植物生长对园林植物进行整形等方面应用的可能性。运用形态观察、植物解剖和生理测定等方法研究了调节膦对榆树绿篱生长的影响。结果表明每年6—8月喷洒2次或3次,每次剂量为0.25g/m~2的调节膦和1次或2次,每次剂量为0.35g/m~2的调节膦效果较好。使用调节膦对榆树绿篱整形是十分有效的,它不仅抑制榆树绿篱生长;而且不影响榆树绿篱的园林观赏效果;同时每年还可以降低40％～50％的抚育费用。
In order to explore the “regulation of phosphine” in inhibiting the growth of garden plants on the plastic plants and other aspects of the application possibilities. Morphological observation, plant anatomy and physiological assays were used to study the effects of phosphine on the growth of elm hedgerows. The results show that spraying 6 or 8 months each year, two or three times, each dose of 0.25g / m ~ 2 and 1 or 2 times to adjust the dose of 0.35g / m ~ 2 for the regulation of phosphine better . The use of phosphine to regulate elm hedgerow shaping is very effective, it not only inhibits elm hedgerow growth; and does not affect the ornamental effect of elm hedgerow garden; but also can reduce 40% to 50% of the annual tuition costs.
