Flower and seedling cultivation substrate and preparation method thereof

Abstract

The invention provides a flower and seedling cultivation substrate and a preparation method thereof, the flower and seedling cultivation substrate comprises the following components in parts by weight: 70-90 parts of cluster aerial roots of nest base part of wild bird's-nest fern and humus in the cluster aerial roots, 5-30 parts of assistant materials, 14-16 parts of straws, 11-13 parts of corn cob core, 7-9 parts of sorghum shell, 7-9 parts of sawdust, 6-8 parts of yellow mealworm dung, 4-6 parts of Perlite, 4-6 parts of medical stone and 1-2 parts of a water-retaining agent, the invention also provides the preparation method of the flower and seedling cultivation substrate, the flower and seedling cultivation substrate improves the ornamental value and economic value, flowers cultured in the flower and seedling cultivation substrate are high in seedling rate, are less prone to disease, have water conservation, erosion resistance, cold resistance, drought resistance and waterlogging resistance, and are suitable for large-scale promotion.

Description

technical field [0001] The invention relates to the field of flower seedling cultivation, in particular to a flower seedling cultivation substrate and a preparation method thereof. Background technique [0002] Soilless cultivation is an emerging advanced flower cultivation technology in recent years. It has the following advantages: good quality, because the hydroponic nutrient solution is prepared according to the needs of flowers, which is conducive to the growth of flowers. Therefore, the flowers are large in shape, strong in taste, bright in color, long in flowering period, and can bloom in advance. Save nutrients, water and labor. Hydroponics only needs to replenish the prepared nutrient solution to the flowers regularly, which is easy to operate and saves labor and time. Clean, no weeds, less pests and diseases. The fertilizer used for hydroponic flowers is a nutrient solution prepared with inorganic elements, which is clean and hygienic. [0003] At present, a va...

Problems solved by technology

[0005] The prior art, for example, Chinese Invention Authorized Patent Document, Authorized Notice No. CN 102391039 B, this invention discloses a flower nursery stock cultivation substrate, which consists of the following components by weight as raw materials, straw 14-16, corn cob 11-13 , sorghum husk 7-9, sawdust 7-9, Tenebrio molitor dung 6-8, perlite 4-6, medical stone 4-6, first prepare the above ingredients into a dry matrix, and then mix with the cultured probiotics liquid Fermented together, the invention makes the waste produced in the agricultural and forestry production process into a cultivation substrate suitable for cultivating flowers and seedlings. It has been proved by experiments that it has the same or even better cultivation effect with peat as the substrate, which proves the invention The cultivation medium of flower seedlings can completely replace peat. This invention adapts measures to local conditions, utilizes a large amount of agricultural and forestry waste resources, and develops a clean and environmentally friendly substrate with low production cost and recyclable use. The contradiction between the total amount of depleted peat resources, but there is still room for improvement in terms of promoting flower growth, prolonging flowering period and water retention performance of the substrate
