Cultivation method for repeated seed collection of verbena hybrida

Abstract

The invention discloses a cultivation method for the repeated seed collection of verbena hybrida. The method comprises the following steps: 1) accelerating germination at low temperature; 2) sowing and seedling raising; 3) thin planting and transplanting; 4) growth management: foliage top-dressing with the combination of watering every other 20-25 days, stopping foliage top-dressing at the end of March of next year, and spraying leaf fertilizer once every other 7-10 days; 5) seed harvest for the first time: harvesting seeds for the first time in early May of next year, foliage top-dressing with the combination of watering every 15 days, stopping foliage top-dressing in early June of next year, and praying leaf fertilizer once every other 7-10 days; 6) seed harvest for the second time: harvesting seeds for the second time in the middle of July of next year, stopping fertilization, watering properly, watering and fertilizing in the middle of August of next year, foliage top-dressing with the combination of watering every other 15-20 days, and spraying leaf fertilizer once every other 7-10 days from the beginning of September of next year; and 7) seed harvest for the third time. According to the invention, the repeated blooming and fructification of the verbena hybrida is effectively facilitated, the seed yield is remarkably increased, and the seed volume-weight is increased.

Description

technical field [0001] The invention relates to a method for multiple seed collection and cultivation of plants, in particular to a method for multiple seed collection and cultivation of cherry cherry blossoms within a period of slightly more than one year, and belongs to the technical field of plant cultivation. Background technique [0002] Beauty cherry, also known as Four Seasons Hydrangea, Beauty Sakura, Padijin, etc., is a herbaceous flower of the genus Verbena in the Verbenaceae family. The stems are four-sided, the branches spread horizontally, the base is prostrate, low and thick, clustered and covered the ground, the whole plant is gray pubescent, 30-50 cm long, opposite leaves with short stalks, oblong, oval Or lanceolate triangle, edge with notched coarse teeth or neat round blunt serrations, leaf base often has cracks, spikes are terminal, most small flowers are densely arranged in a corymb shape, bracts are nearly lanceolate, calyx is thin Long tube-shaped, 5...

Problems solved by technology

At present, the traditional mode of cherry blossom seed picking and cultivation is one planting and one harvesting. Generally, it is sowing in autumn, flowering in spring, and harvesting seeds in early summer. In the northern region, it is sowing in spring and picking in autumn. The germination rate of this cultivation method is low, and the germination rate is less than 30%. , and the germination is irregular, the growth cycle is long, the cost is high, and the bulk density of the cherry cherry seeds is low (the bulk density is the weight of the seed per unit volume, which reflects the fullness of the seeds. The weight of a liter of seeds is the bulk density of the seeds. The larger the bulk density, the better The higher the higher), the lower the reproductive output
