Controlling tree growth

摘要

East Mailing Research scientists Chris Atkinson, Neil Hipps and Mike Davies report on an experiment to restrict roots to regulate tree sizes with the help of geotextile membranes. The idea that restricting the growth of roots provides a means to control plant growth has been known for thousands of years. The Japanese and Chinese have practised the art of "bonsai" probably for at least 1,000 years. We are all also well aware of the benefits of root restriction as a horticultural practice, where not only the unwanted vegetative shoot growth (the bonsai effect) is reduced, but where there is also a promotion of the diversion of photosynthetic carbohydrates into fruit dry matter and yield.
