Description
Technical field
The present invention relates to the technical field of crop-planting, in particular to the acclimation method of hydroponic flowers.
Background technology
As modern metropolitan cities people's rhythm of life is increasingly accelerated, hydroponic flowers quietly enter our life.It is popular next
It is a kind of innovation of plant culture pattern to say water planting, is that some traditional potted plant patterns are converted into glass container water to support pattern,
To reach the full room of the fragrance of a flower above, below the landscape effect enjoyed a trip to of fish, hydroponic flowers sight is stronger, both considerable leaf reward root,
Fish can be appreciated again, while the artistic effect that can be optionally combined again, without native environmental protection, it is easy to manage.
Hydroponic flowers refer to without soil, and with the method for the floriculture such as nutrient solution or solid matrix Ensure Liquid liquid.Flower
Grass domestication, which refers to tame in the finished product flower of earth culture, grows a certain amount of water root with aerating tissue, allows plant to adapt to nutritious
The aquatic planting environment of liquid and continued growth.
Water planting has very big difference in terms of root system of plant environment, is especially embodied in root system compared with soil cultivation
In terms of oxygen environment and ion concentration.Water planting is the direct cultivation mode with nutrient fluid cultivation, and root system of plant will necessarily be in weak oxygen
Environment in;Border root system is directly contacted with nutrient solution, without cushion space, and the concentration of the different ions in nutrient solution is directly affected
Absorption of the plant for the ion.If plant is root system is without domestication during soil cultivation into solution culture, plant very may be used
It can will not adapt to water planting environment and dead.
In the prior art, because the effect of acclimation method is poor.
The content of the invention
In view of this, the invention reside in a kind of acclimation method of hydroponic flowers is provided, the acclimation method, which has, preferably tames and dociles
Change effect.
A kind of acclimation method of hydroponic flowers, comprises the following steps:
The root system implantation aqueous medium of flowers is subjected to slow seedling processing, the depth of the flowers implantation aqueous medium is may be such that
Root system is stated to be at least partially exposed to air to grow aerial root;
The flowers that the slow seedling is handled carry out water planting plantation.
Further, the height that the root system is located in aqueous medium is 0.3~1.5cm.
Further, the time of the slow seedling processing is 3~10 days.
Further, the slow seedling processing is in 100~150 μm of olm-2·s-1Intensity of illumination under carry out.
Further, the aqueous medium is clear water.
Further, it is 1.5~2.5ms/cm that the water planting, which plants nutrient solution used EC concentration, and pH is 6~7.
Further, it is 3~15mg/L that the water planting, which plants nutrient solution used dissolved oxygen content,.
Further, the intensity of illumination of the water planting plantation is 180~300 μm of olm-2·s-1, the water planting plantation
Periodicity of illumination is 10~15h.
Further, the root system is fixed through fixing device, and the fixing device is the field planting basket for being built-in with fixed matrix.
Further, also include root is cleaned, sterilized and taken root after elder generation successively before the step of slow seedling is handled
Processing.
The flowers that root system is fixed through fixing device are implanted into aqueous medium first and entered by the acclimation method of the hydroponic flowers of the present invention
The processing of row slow seedling, causes the root system to be at least partially exposed to air to induce aerial root during slow seedling processing,
Slow seedling processing, which may be such that, has tentatively adapted to water environment, and grown a certain amount of water root with aerating tissue, then passes through
Water planting, which is planted, to adapt to water environment completely, which thereby enhances domestication effect.
