Method for breeding clematis maple seeds

Abstract

The invention discloses a method for breeding clematis maple seeds, and relates to the technical field of cultivation. The method comprises the following steps of (1) sowing: dibbling the clematis maple seeds in a culture medium, watering thoroughly, covering with a film for moisturizing, shading and accelerating germination; (2) cotyledon stage management: removing the film after the seedlings germinate, performing shading management, watering twice a day, and keeping the culture medium moist; (3) management in a true leaf period: after true leaves grow out, moving the seedlings to a natural light environment with the light intensity of 4000-12000 lux, watering once a day, and applying a nitrogen-phosphorus-potassium full-proportion water-soluble fertilizer once a week till a dormancy period in winter; (4) next-year management: in a natural illumination environment with the illumination intensity increased to 30000-50000 lux in the next year, applying the nitrogen-phosphorus-potassium full-proportion water-soluble fertilizer once a week, and watering according to the principle that the water is dry and wet. Compared with wild reproduction, the method has the advantages that the germination rate and the survival rate of the seeds are remarkably increased, precocious flowering is promoted, and the seeds can overwinter in the open field in south of Beijing.

Description

technical field [0001] The invention relates to the technical field of cultivation, and more specifically relates to a method for seed propagation of clematis maple leaf. Background technique [0002] Clematis maple leaf is a perennial erect shrub of the genus Clematis, which is native to Beijing and grows in limestone cliffs. Clematis plants have beautiful flower and fruit shapes and strong adaptability. They are excellent vertical greening plants and one of the commonly used landscape flowers at home and abroad. They are often used in flower walls and style columns in garden applications, and they are also indispensable for creating landscapes in vertical space. It is an excellent plant species that is lacking, and has extremely high horticultural ornamental value. [0003] Clematis plants are known as the "Queen of Fujimoto", but most clematis species perform poorly in garden applications in northern regions. The reason is that most of them come from European and America...

AI Technical Summary

Problems solved by technology

[0003] Clematis plants are known as the "Queen of Fujimoto", but most of the clematis species perform poorly in garden applications in northern regions, because most The variety comes from European and American countries, and its heat resistance is poor, and the introduction and utilization of clematis plants adapted to the northern environment are seldom used, which makes it impossible to further cultivate potted flowers.
