Cultivation method capable of improving red leaf characters of euonymus alatus cv. 'Compacta' and prolonging ornamental period

Abstract

The invention relates to a cultivation method capable of improving red leaf characters of euonymus alatus cv. 'Compacta' and prolonging the ornamental period. The method comprises steps as follows: illumination, watering, adjustment of pH of soil, fertilization, spraying of a plant growth regulator and spraying of a bordeaux mixture. Through regulation of each factor in the growth process of euonymus alatus cv. 'Compacta', the ornamental period of the euonymus alatus cv. 'Compacta' planted in the northern coastal saline region is advanced to the first ten-day period of October, the leaf fall period is delayed to the first ten-day period of November, and the ornamental period is prolonged by about 15 days as compared with a conventional planting method. Moreover, more than 90% of leaves areall red, the leaves are bright, and the ornamentation is greatly increased.

Description

technical field [0001] The invention relates to a cultivation method for improving the ornamental properties of color-leaved plants, in particular to a cultivation method for making euonymus red leaves redder and prolonging the viewing period in coastal saline-alkali areas. Background technique [0002] With the development of urban gardens, greening can no longer meet people's needs, and colorization is becoming a new trend, so how to better apply colored leaf plants has become an urgent problem to be solved. Euonymus alatus cv.'Compacta', Euonymus alatus, Euonymus genus, is a good ornamental plant with colorful leaves in autumn. The leaves are dark green in spring and summer, and turn red in autumn. The average temperature in winter is lower than The leaves fall at 5°C, the flowering period is from May to June, and the fruiting period is from September to November. Flame euonymus is a variant of euonymus, a new and excellent color-leaved plant introduced from abroad. It i...

In addition, secondary salinization caused by salt dust also poses a great threat to the growth of plants

Euonymus flamingo can be planted in saline-alkali land through introduction and domestication, but the red leaf character of Euonymus flamingo cannot be reflected due to the alkaline soil environment, so that Euonymus flamingo cannot be used as a color-leaf plant in landscaping

In addition, climate and soil conditions lead to early leaf fall of Euonymus flamingo, which also greatly affects the application of this plant
