Embodiment Construction

[0018] The present invention will be further described.

[0019] Perennial flowers generally have different flowering mechanisms, and this special flowering mechanism is a key factor affecting the success of perennial flower cultivation.

[0020] During the cultivation of perennial flowers, two elements need to be focused on: photoperiod and low temperature cultivation.

[0021] Perennial flowers need to be stimulated by an appropriate photoperiod to bloom; while low-temperature cultivation mainly refers to the vernalization stage. Successful vernalization must meet three conditions: 1. The plants to be vernalized must be fully mature; 2. It must be carried out in a suitable low temperature environment, generally around 3-5°C. 3. It must be stored in a low temperature environment for a sufficient time, generally about 6-10 weeks; in addition, it should be noted that before low temperature treatment, the plants must have a vegetative growth period of 2 months.

Abstract

The invention discloses a novel variety seedling-raising method for cold-tolerant drought-tolerant perennial flowers. The method comprises the following steps: 300 L of peat is adopted to package 100-120 200-hole plug trays, and sowing is performed in January to March; potting is performed in March to May, and the time that when plug tray seedling roots just grow out of ventilation holes at the bottom of each plug tray and the roots are clustered is the best time for transplanting; after potting and seedling recovering are performed, pots are put into a greenhouse with temperature of 0-5 DEG Cto be kept for 1-1.5 months, and therefore the flowering amount and quality can be significantly increased; and after the plug tray seedlings are formed, the seedlings are transplanted to a 50-hole or 8*8 nutrient bowl or a commercial pot in one step, after the seedlings are recovered for 2-4 weeks, the seedlings are moved to a greenhouse with night temperature of 0-5 DEG C and daily temperatureof 10-15 DEG C to be placed for 1.5-2.5 months, humidity in the pots is checked regularly, and a medium in the pots is always to be kept in a moist state. The scheme provided by the invention greatlyshortens cultivation time of the perennial flowers, brings better effects to standardized seedling raising of the perennial flowers, and improves flowering quality, thereby bringing a gospel to cold and arid regions in northern China.

Description

technical field [0001] The invention relates to the field of flower artificial planting, in particular to a method for growing seedlings of new varieties of cold- and drought-resistant perennial flowers. Background technique [0002] Perennial flowers refer to perennial herbaceous flowers whose roots persist in the soil in winter and can re-germinate in the next spring. The underground parts of this kind of flower plants usually have a relatively developed root system, which can survive for several to decades. Perennial flowers have strong adaptability, drought tolerance, less pests and diseases, easy cultivation, simple maintenance, low cost, quick results, and can create Fresh and natural garden landscape and other characteristics have attracted people's attention, and are widely used in urban greening. [0003] Since the 1990s, my country's landscaping construction has developed by leaps and bounds, and the contradiction between large-scale greening and water shortage ha...
