Disease-and-pest-resistance camellia seedling cultivating medium and application method thereof

Abstract

The invention provides a disease-and-pest-resistance camellia seedling cultivating medium and an application method thereof. The seedling cultivating medium is prepared from vermiculite, peat, coal residues, tobacco sticks and a water-retaining agent, and is divided into two layers, the vermiculite, the peat and the coal residues are mixed to be uniform to serve as the lower-layer medium, and thetobacco sticks and the water-retaining agent are mixed to be uniform to serve as the upper-layer medium. When the disease-and-pest-resistance camellia seedling cultivating medium is used, the lower-layer medium is laid, camellia seedlings are planted into the lower-layer medium, then the upper-layer medium is laid, land is thoroughly watered, and moisture is supplemented in time. The disease-and-pest-resistance camellia seedling cultivating medium is good in physical and chemical property and low in cost, medium preparing and using steps are simple, organic materials are not required to be fermented and aged, the survival rate of cultivated camellia seedlings is high, few diseases and pests occur, plants grow robustly, and the requirement of commercialized camellia seedlings is met.

Description

technical field [0001] The invention relates to the field of horticultural substrates, in particular to a pest-resistant camellia seedling-raising substrate and a use method thereof. Background technique [0002] Camellia is one of the ten famous traditional flowers in my country, and is known as the treasure of flowers. Camellia has beautiful branches and green leaves, bright and colorful flowers, beautiful and diverse flower shapes, elegant and diverse flower postures, fragrant fragrance, and various varieties. Most of the flowers are red or light red, and some are white. They are cherished by the world's horticultural circles. Camellia is native to eastern China and is widely planted in the Yangtze River Basin, Pearl River Basin, Chongqing, Yunnan and Sichuan, as well as Korea, Japan, Taiwan and India. [0003] The substrate is the growth basis of the camellia, because the root system of the camellia depends on the substrate for growth and development, and the water and ...

AI Technical Summary

Problems solved by technology

[0005] It can be seen that although this method can be used to produce and prepare camellia seedling substrates, the method has complicated steps, and a large amount of organic materials are used, and the organic materials need to be fermented and aged. If the organic materials are not fermented thoroughly, the nutrients in the aging process If it is not fully decomposed and released, the prepared seedling substrate is very easy to carry germs and insect eggs, resulting in frequent occurrence of diseases and insect pests in the seedling cultivation, and the organic materials that have not been fully fermented and aged will be further decomposed under certain moisture and ventilation conditions. Cause burnt roots, smoked seedlings, etc.
