Efficient liquid fertilizer for culturing eustoma grandiflorum and preparation method thereof

Abstract

The invention relates to an efficient liquid fertilizer for culturing eustoma grandiflorum and a preparation method thereof, and belongs to the technical field of organic fertilizers. According to the growth characteristics of the eustoma grandiflorum, the efficient liquid fertilizer suitable for growing the eustoma grandiflorum is prepared from bone meal, fish meal, tartary buckwheat bran, fermented bagasse fine powder in a ratio of (2.5 to 3.5):(3 to 6):(4 to 8):(5 to 10), wherein 5 percent of phosphate fertilizer, and 100 to 150 times of spring water or well water by weight are additionally added. The preparation method comprises the following steps: pouring the materials into a special fertilizer mixing tank in proportion, and stirring uniformly; fermenting the mixture for 4 to 5 months; and after the fermentation is matured, extracting supernatant fluid in batches for spray fertilization of the eustoma grandiflorum. The efficient liquid fertilizer can effectively promote the growth of germchits of the eustoma grandiflorum and ensure that the flower quality is good, the eustoma grandiflorum blooms 5 to 15 days in advance, and the quality of cut flowers is effectively improved. The efficient liquid fertilizer provides a technical and quality assurance for quick cultivation of the eustoma grandiflorum, achieves an active promotion function for meeting the living needs of people, and has a good economic benefit.

Description

technical field [0001] The invention belongs to a high-efficiency liquid fertilizer for eustoma flower cultivation. Background technique [0002] Eustoma grandiflorum, also known as prairie gentian, is native to Nebraska and Texas in the United States. It is a plant of the Gentianaceae grassland Gentiana, and it is a one-year or two-year herb. Hi warm, humid and sunny. More cold-resistant, not resistant to water and humidity. Introduced to Europe and Japan through crossbreeding and improvement, it has now become a seductive and unusually novel flower. The plant height is 30-100 cm. Leaves alternate, broadly elliptic to lanceolate, almost sessile, leaf bases slightly clasping; leaf surface blue-green. The stamens are obvious, the bracts are narrow and lanceolate, and the petals are imbricate. [0003] The optimum temperature for the growth of eustoma is 15-28°C, and the night temperature during the growth period is not lower than 12°C. When the temperature is below 5°C...

Problems solved by technology

Although the industry has begun to take shape, nearly 60% of eustoma seedlings still rely on imports, and technical barriers have become the primary problem restricting the large-scale promotion of eustoma cut flowers
