Method for prolonging viewing period of sapium sebiferum

Abstract

The invention discloses a method for prolonging a viewing period of sapium sebiferum. The method comprises the step of regularly spraying an aqueous solution of potassium dihydrogen phosphate or saccharose to sapium sebiferum cutting seedlings before the viewing period. Compared with the prior art, the method has the advantages that the increase of accumulation of saccharides and other nutrients in leaves of the sapium sebiferum is facilitated; the growing period of the leaves is prolonged due to the increase of the nutrients, so that the viewing period is prolonged; the content of anthocyanin is increased due to the accumulation of the saccharides, so that the ratio of the anthocyanin to chlorophyll in the leaves is increased, and thus, the brightness of the leaves is improved.

Description

technical field [0001] The invention belongs to the field of tree cultivation, and in particular relates to a method for prolonging the viewing period of Chinese tallow tree. Background technique [0002] Chinese tallow tree is a traditional garden landscape tree species in my country, which has high ornamental value. In autumn, the leaves of Chinese tallow tree have rich changes in color, rendered in red, yellow, orange, purple and other colors. They are gorgeous and have high ornamental value. They are the main tree species in many autumn red leaf scenic spots. This tree species has the characteristics of drought tolerance, waterlogging tolerance, salt-alkali tolerance, etc., grows rapidly, and has no strict requirements on soil. It has broad application prospects in the color afforestation of hilly and barren mountains in Jiangsu, low-humidity beaches of rivers and lakes, and coastal saline-alkali land. However, the time from discoloration to leaf fall of Chinese tallow ...
