Hydroponic seedling cultivation method of lindera communis

Abstract

The invention discloses a hydroponic seedling cultivation method of lindera communis. The method comprises the following step of S1, lindera communis seed selection and pretreatment; S2, seed disinfection and germination accelerating; S3, sowing and seedling raising; S4, lindera communis bud seedling hydroponics and cress seedling intercropping; S5, nursery transplanting. Accordingly, lindera communis bud seedlings and cress seedlings are creatively subjected to intercropping and hydroponic seedling raising, the root environment of the lindera communis bud seedlings is adjusted by means of secretory substances of roots of the hydroponic cress seedlings, and the capacity of being resistant to diseases and insects of lindera communis root systems is improved; by innovating a lindera communisseed treatment method, the seed germination rate is increased, and the robust level of the seedlings is improved; by preparing a hydroponic nutrient solution, high-quality nutrient supply conditionsare provided for lindera communis hydroponic seedlings; finally, for the lindera communis planted through the technical method, annual seedling plants are robust, the seedling height, ground diameter,crown width and the like are higher than those of a conventional seedling raising method, a high-quality guarantee is provided for later transplanting cultivation, and the method has important industrial innovation application value.

Description

technical field [0001] The invention relates to the field of forest tree planting, in particular to a method for planting fragrant-leaf seedlings in water. Background technique [0002] bay leaf tree ( Lindera communis Hemsl ) is an evergreen arbor tree species of the lauraceae mountain pepper, also known as fragrant fruit tree, fine-leaved camphor tree, Qianjin incense, Qianjin tree, wild ginger, fragrant leaves, large fragrant leaves, etc. It has strong adaptability, good dry shape, and rapid growth It is suitable for urban landscape tree species. Fragrant leaf tree is a subtropical evergreen broad-leaved tree with many distribution areas, mainly in Shaanxi, Gansu, Hunan, Hubei, Jiangxi, Zhejiang, Fujian, Taiwan, Guangdong, Guangxi, Yunnan, Guizhou, Sichuan and other provinces. Fragrant leaf tree is an excellent material, medicinal and ornamental multi-purpose tree species. Its wood structure is fine, heavy and rot-resistant. It is an excellent material for making agricu...

Problems solved by technology

Wang Qiaozhen, Mao Shuiwang, and Xu Shaojian conducted research on the seedling raising technology of Ayurvedic edulis in Fujian, and Shen Lixin conducted a preliminary research on the seedling raising technology of Ayurvedic edulis in Tengchong County, Yunnan. , container, substrate and root cutting treatment, etc., although the predecessors have carried out some experiments and discussions, the research on the artificial planting and seedlings of fragrant-leaf trees is still relatively rare, and the research on water seedling technology research is rarely seen in public reports, leading to the current The artificial seedling raising technology of domestic sweet-leaf tree is not up to standard, and cannot provide enough high-quality seedlings for artificial forestation of sweet-leaf tree, and seedling cultivation is an important part of forest cultivation. The quality of seedlings affects the quality of artificial forestation, so it can be said that the current fragrant Seedling cultivation technology of Leaf tree restricts the large-scale and industrialized development of the plantation
