Soilless culture medium for India cannas and preparation method thereof

Abstract

The invention discloses a soilless culture medium for India cannas. The soilless culture medium consists of, by weight, the following raw materials: 8-10 parts of coptis chinensis, 3-5 parts of honeysuckle flowers, 4-6 parts of monkshood, 30-35 parts of bagasse, 5-8 parts of bean dregs, 5-8 parts of urea, 1-3 parts of glycine, 1-3 parts of salicylic acid, 0.5-1 part of brassinolide, 3-5 parts of watermelon peel and 50 parts of rice washing water. The preparation method of the soilless culture medium for India cannas mainly comprises the steps of crushing traditional Chinese medicines, preparing a nutrient solution and executing fermenting and mixing processes. By adopting the soilless culture medium, the physical and chemical properties of original single medium are improved, structural pores of the medium are remarkably enhanced, the nutritional ingredients and the medium environment required by India cannas are greatly met, the plant firmness and the stem toughness are improved, accordingly the ornamental value of plants is improved, and the rapid development of India canna planting in the soilless culture industry is facilitated.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and relates to a canna soilless cultivation substrate and a preparation method thereof. Background technique [0002] Canna (Canna indica), also known as Lanjiao and Tanhua, is a plant of the family Cannaceae and the genus Canna. It is a perennial bulbous herb flower native to tropical America and Africa. The plant height of canna can reach 100-180cm. It grows in clusters, with large leaves and rich colors, large flowers, bright colors, various colors, and long flowering period. It is a very good landscaping and landscaping plant. Canna leaves can absorb harmful substances such as sulfur dioxide and hydrogen chloride. Although the leaves are vulnerable, they can regenerate new leaves and quickly resume growth. Therefore, they can be used as indicators for monitoring harmful gas pollution, purifying the air and protecting the environment. In addition, canna can also be used as medicine ...

AI Technical Summary

Problems solved by technology

At present, peat is generally used as the main raw material for the culture medium. Since peat is a non-renewable resource and its demand is increasing year by year, the cost of the substrate is relatively high. If the substrate components are not properly configured, the cultivated crops are prone to malnutrition. Soilless cultivation substrates generally have the problem of poor buffering capacity, which leads to unsmooth water and fertilizer supply and discharge in the later stage. In the long run, cultivated crops are prone to rotten roots or insufficient nutrient absorption
