Cultivation substrate for large-flowered dwarf zinnia

Abstract

The invention relates to the field of compost, in particular to a cultivation substrate for large-flowered dwarf zinnia. The cultivation substrate for the large-flowered dwarf zinnia is prepared fromthe following raw materials: cassava residues, earthworm soil, garden humus soil, peat, perlite, a pH regulator and a plant growth regulator. A preparation method of the cultivation substrate for thelarge-flowered dwarf zinnia comprises the following steps: (1) preparing garden humus soil; (2) mixing materials; and (3) adding auxiliary materials. According to the invention, long-acting sufficientnutrients can be provided for the zinnia by designing the cultivation substrate for the large-flowered dwarf zinnia, the flowering quality of the zinnia is improved, and the flowering period is prolonged. The humus soil prepared by crushing garden organic wastes is rich in nutrition; by virtue of the use of cassava residues, waste is converted into treasure; and by adding the natural plant growthregulator, the healthy growth of the plants can be promoted. The cultivation substrate for the large-flowered dwarf zinnia is wide in source of raw materials, simple and easy to obtain; the organic wastes are used to produce the zinnia cultivation substrate, so that the environmental pollution caused by stacking and burning of the organic wastes can be reduced, and the economic and environmentalbenefits are good.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a cultivation substrate for dwarf zinnia grandiflorum. Background technique [0002] As of the end of 2017, the total area of ​​protected horticulture in the world was about 4.6 million hectares, of which the protected horticultural area of ​​China, Japan and South Korea in Asia accounted for about 82.90% of the world's total protected horticultural area; from the perspective of development scale, China's protected horticultural area 3.7 million hectares, ranking first in the world, accounting for about 80.43% of the world's total protected gardening area; from the perspective of cultivated crops, it is mainly vegetables, fresh cut flowers and potted flowers. In 2007, the planting area and sales volume of potted flowers in China were 77,300 hectares and 4.033 billion pots, respectively. In 2016, the planting area and sales volume reached 105,800 hectares and 7.084 billi...

AI Technical Summary

Problems solved by technology

[0006] At present, most commercial cultivation substrates cannot meet the needs of the whole growth period of Zinnia, and the lower leaves turn yellow and wither off in the middle and late stages of growth; after the full flowering period, they cannot continue to provide sufficient nutrients, the number of flowers decreases, and the flowering period shortens, which seriously affects the viewing of Zinnia with applied effects
