Embodiment 1

[0017] (1) Selection of Araucaria heterophyllum seedlings: Select potted seedlings of Araucaria heterophyllum 3-year-old potted seedlings grown in soil in the flower market;

[0018] (2) Treatment of soil-baked root system: Take the selected seedlings out of the flowerpot or nutrient bowl, carefully remove the soil from the root system to avoid damage to the root system, wash the soil on the root system with running water, and clean the root system Soak in 0.05wt% potassium permanganate solution for 20 minutes, take it out and rinse with tap water for 3 minutes;

[0019] (3) Preparation of water bacon induction solution: first prepare the basic nutrient solution by adding calcium nitrate tetrahydrate (Ca(NO 3 ) 2 4H 2 O) 472 mg, potassium nitrate (KNO 3 ) 202mg, ammonium nitrate (NH 4 NO 3 ) 80mg, potassium dihydrogen phosphate (KH 2 PO 4 ) 100mg, potassium sulfate (K 2 SO 4 ) 174mg, magnesium sulfate heptahydrate (MgSO 4. ·7H 2 O) 246mg was dissolved in 700ml of di...

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 [0001] The invention relates to a method for inducing and cultivating roots of Araucaria heterophyllum in the process of converting from soil culture or substrate cultivation to hydroponics, in particular to a method for selecting Araucaria heterophyllum plants suitable for hydroponics. The invention relates to the treatment of the roots of Araucaria heterophyllum plants, the preparation of nutrient solution induced by hydrobasic roots, and the preparation method of nutrient solution for promoting the vigorous growth of Araucaria heterophyllum in water, belonging to the technical field of hydroponic production of woody plants. Background technique [0002] Araucaria heterophylla is in the shape of a spire, its trunk and roots are bronze-colored after peeling; its branches and leaves are lush and green all the year round, its roots and branches are easy to shape, and its body is beautiful and beautiful. It is one of the world-renowned garden trees. It can also...
