Method for improving ornamental quality of radix curcumae

The invention discloses a method for improving the ornamental quality of radix curcumae. The attapulgite can improve the dry matter content of the radix curcumae seedballs, increase the number of flowering branches of the radix curcumae, prolong the service life of the inflorescence of the radix curcumae, remarkably improve the ornamental value of the radix curcumae, inhibit vegetative growth of the radix curcumae and dwarf plants. Therefore, the ornamental quality of the radix curcumae can be improved by topdressing the attapulgite during the cultivation period. 本发明公开了一种提升火炬郁金观赏品质的方法。凹凸土可提高火炬郁金种球的干物质含量、增加火炬郁金的花枝数量，延长火炬郁金花序寿命，显著提高了火炬郁金的观赏价值，并抑制了火炬郁金的营养生长，矮化植株。因此可以在栽培期间通过追施凹凸土能提升火炬郁金的观赏品质。
