Embodiment 1

[0015] Arrange the dwarf cosmos that needs to be pretreated after planting. Weigh sodium hydrosulfide and add water to prepare an aqueous solution with a concentration of 80 μmol / L, which is ready-to-use. Every time between 8:00 am and 10:00 am, spray the dwarf cosmos to be treated evenly with 80 μmol / L sodium hydrosulfide aqueous solution, once every other day, and treat 15 times continuously. The results showed that after 15 treatments, the dwarf cosmos flowered an average of 7 days earlier, and the flowering period was prolonged by 7 days.

Embodiment 2

[0017] Place the zinnias that need to be pretreated after planting in an outdoor ventilated place. Weigh sodium hydrosulfide and add water to prepare an aqueous solution with a concentration of 60 μmol / L, which is ready-to-use. Each time between 8:00 and 10:00 in the morning, the zinnia to be treated was evenly sprayed with 60 μmol / L sodium hydrosulfide aqueous solution, once every other day, and treated continuously for 15 times. The results showed that after 15 treatments, Zinnia bloomed 10 days earlier on average and extended the flowering period by 15 days.

Embodiment 3

[0019] Place the alyssum bulbs that need to be pretreated after planting in an outdoor ventilated place. Weigh sodium hydrosulfide and add water to prepare an aqueous solution with a concentration of 80 μmol / L, which is ready-to-use. Each time between 8:00 and 10:00 in the morning, the Zinnia to be treated was evenly sprayed with 80 μmol / L sodium hydrosulfide aqueous solution, once every other day, and treated continuously for 15 times. The results showed that after 15 treatments, the flowering period of Alyssa aurantium was 7 days earlier and the flowering period was prolonged by 8 days on average.

Abstract

The invention discloses new application of sodium hydrosulfide for supplying hydrogen sulfide and promoting blooming of flowers and prolonging flowering phase, in particular relates to application of sodium hydrosulfide for supplying hydrogen sulfide and advancing and prolonging the flowering phase of flower plants. The sodium hydrosulfide for supplying hydrogen sulfide has an effect of advancing the flowering and prolonging the flowering phase of living flower plants such as cosmos bipinnatus, zinnia elegans jacq., lobularia maritima and garden balsam. The research shows that sodium hydrosulfide for supply H2S is used for preprocessing flower plants, so that the growth of leaves can be remarkably promoted, the chlorophyll content and photosynthesis rate of plant leaves can be increased, the flower can be flowered 5 to 15 days earlier, and the flowering phase of the flower can be remarkably prolonged. The reagent is single and easy to acquire, simplicity in operation can be achieved, and a novel technical scheme is provided for solving the problem of urgent demand on flowering of flower plants in short period.

Description

technical field [0001] The present invention relates to a new application of a known compound, specifically a new application of sodium hydrosulfide which can release hydrogen sulfide gas to promote flowering plants in advance and prolong their flowering period. Background technique [0002] Flowering is the most important process in the transformation of plants from vegetative growth to reproductive growth. The relatively fixed flowering time of each plant is necessary for plants to achieve reproductive development. With the progress of society and the improvement of living standards, people's demand for flowers is becoming stronger and stronger, whether it is urban construction or daily life. Therefore, shortening the breeding period, advancing and prolonging the florescence of flowers has always been a research focus of agronomists and horticulturalists. [0003] At present, the research and development of improved varieties is the most common method to shorten the growt...
