Abstract
The invention relates to a root inducing and culturing technique for araucaria heterophylla during hydroponics transferred from earth culturing or substrate culturing, in particular to the technique including selection of araucaria heterophylla suitable for hydroponics, treatment of the roots of araucaria heterophylla before hydroponics, preparation of the root inducing nutrient solution in hydroponics and preparation of nutrient solution for the better growth of the araucaria hydroponics, and belongs to the technical field of woody plant hydroponics. By the root inducing and culturing techniques, the araucaria heterophylla is changed from earth culturing or substrate culturing to hydroponics, and preparation formula of root inducing and growing nutrient solution in hydroponics and the matching technique with low rate of root rotting, high rate of root inducing water, large amount of thick hydroponics roots and robust plants are provided. The root inducing and culturing technique for araucaria heterophylla hydroponics can be applied to the factory production of araucaria heterophylla soilless nutrient solution and home planting hydroponics.
Description
Technical field
The present invention relates to a kind of different leaf araucaria and transferred to the method for water planting root induction and cultivation in the water planting process by earth culture or substrate culture, be particularly related to the selection of a kind of different leaf araucaria plant of suitable water planting, the processing of different leaf araucaria plant root before water planting, the preparation of water planting root induction nutrient solution, promote the compound method of the nutrient solution of the healthy and strong growth of the different leaf araucaria of water planting, belong to woody plant water planting production technical field.
Background technology
The tree-like steeple shape of different leaf araucaria is bronze-colored after its trunk and root decortication; The luxuriant four seasons of branches and leaves are bud green, and root and limb are easy to moulding, and the figure is beautiful attractive in appearance, are one of world-renowned flower garden tree.Also can be used as the background tree of large-scale sculpture or landscape building.Intersperse environment in potted plant applicable vestibular or the hall.But different leaf araucaria is all take the soil cultivation as main for a long time, and soil is planted the quarantine problems such as damage by disease and insect of bringing and restricted its export trade and outlet, becomes the bottleneck that restriction araucaria industry further develops.
Hydroponic flowers is a kind of form with nutritional liquid grown plant.Make the culture matrix of plant of nutrient solution, have without soil cleaning, see that flower sees the characteristics such as Ye Jiangen, maintenance are convenient, simultaneously can also the prepared generation of avoiding and preventing a lot of root disease and pests.The problems such as the woody ornamentais water planting exists root system easily to rot, and the water planting root induction is difficult, and water planting root induction rate is low, and water planting is not durable.
The different leaf araucaria of water planting has solved the quarantine problems such as soil-borne disease insect pest that native cultivation brings, for this plant export trade and outlet provide quality guarantee; The ornamental value of fully having showed different leaf araucaria root, stem, leaf simultaneously.
Summary of the invention
The present invention seeks to transfer different leaf araucaria to water planting by earth culture or substrate culture mode, provide a cover to guarantee that the root system rotting rate is low, water planting root induction rate is high, water planting radical order is many and sturdy, the water planting root induction nutrient solution of plant strain growth stalwartness and hydroponics growing nutrient solution prescription and supporting technology.This invention can be used for different leaf araucaria and produces without native nutrient solution batch production and the house hydroponics applications.
The objective of the invention is to realize by the following technical solutions.High-efficient Water root induction and the cultural method of a kind of different leaf araucaria that proposes according to the present invention comprise the steps:
