Special pink hydrangea flower fertilizer and preparation method thereof

Abstract

The invention relates to a hydrangea flower planting technique, in particular to a special pink hydrangea flower fertilizer and a preparation method thereof, and aims to solve the problem of fertilizing pink hydrangea flowers. The special pink hydrangea flower fertilizer is prepared from the following monomer fertilizers by the following steps: uniformly mixing 180-210 parts of calcium ammonium nitrate, 55-70 parts of monoammonium phosphate, 200-240 parts of monopotassium phosphate, 450-480 parts of ammonium phosphate-nitrate and 30-40 parts of chelated iron according to a mass ratio, crushing, screening by using a screening net of 2mm, uniformly mixing for a second time, and performing quantitative packaging. The special pink hydrangea flower fertilizer is balanced in nutrient structure,reasonable in fertilization amount and capable of maintaining normal growth of hydrangea flower plants, immobilizing aluminum ions in soil and providing effective iron element nutrition, and the hydrangea flowers are of a glossy pink color, and plants are nutritive and grow strongly.

Description

technical field [0001] The invention relates to hydrangea planting technology, in particular to a special fertilizer for pink hydrangea and a preparation method thereof. Background technique [0002] Hydrangeas are native to China and Japan. Hi warm, humid and semi-shady environment. The optimum temperature for hydrangea growth is 18-28°C, and the temperature in winter is not lower than 5°C. It takes 6-8 weeks for flower bud differentiation at 5-7°C, 20°C can promote flowering, and maintaining 16°C after flowering can prolong the flowering period. But the high temperature makes the flowers fade quickly. Hydrangea is a short-day plant, treated in darkness for more than 10 hours a day, and flower buds will form in about 45-50 days. Usually cultivated to avoid the scorching sun, 60%-70% shade is the most ideal. The soil is loose, fertile and well-drained sandy loam. However, the change of soil pH makes the flower color of hydrangea change greatly. [0003] Commercialized...

AI Technical Summary

Problems solved by technology

The fertilizers currently on the market can only ensure that the hydrangea turns pink, but the purity of the flower color powder is not enough or it is white; the commercialized hydrangea is a fresh cut flower, and its commodity value mainly lies in the diameter of the flower ball and the purity of the flower color, so it is required to be planted. During the fertilization process, the ingredients in the fertilizer are well controlled, so that the hydrangea maintains the purity of the flower color. The hydrangea currently planted is prone to iron deficiency and yellowing plants during plant growth, such as figure 1 As shown, the center of the flower ball may have a high degree of pink purity, but the surrounding petals are still white, and even show variegated colors, resulting in a decrease in the quality of the hydrangea flower ball and affecting the economic benefits of flower farmers.
