Description

A kind of be used for plant stand upside down in the air the cultivation medium

Technical field

The utility model relates to a kind of plant culture, particularly relates to a kind of medium that plant is stood upside down and cultivates that is used in the air, belongs to the agricultural cultivation field.

Background technology

The aerial handstand cultivation of plant is an emerging technology of sight-seeing agriculture, be with plant planting in medium and reversal of the natural order of things aloft, cause plant root last stem under growth conditions, when flowering of plant just can be built the effect that flowers and fruits hang in the sky as a result the time.Aerial cultivation has very high sight, and it is also rising in sight-seeing agriculture, courtyard greening, to be popular.But; Because plant root growth has geotropism on the one hand; Moisture in the medium is owing to action of gravity concentrates on training matrix lower floor on the other hand, and therefore inevitable technical problem is geotropism and the growth downwards all the time of hydrotactic characteristic because of root system of plant when being inverted plantation to plant.Because plant is the plantation of standing upside down; Root system of plant growth downwards can cause two difficulties: one, because root system of plant growth downwards all the time; The planting container lower layer space can be more and more crowded, and root growth can not get adequate space, so plant root growth is frail, nutrient absorption capability is not enough; Two, because Root Distribution is concentrated, cause fierce, the nutrient levels relative deficiency of root-room nutrient contention.Finally cause aerial handstand plant of standing upside down cultivation to be in the irregular growth state.

In existing document, do not disclose and be specially adapted for the medium technical scheme that plant is stood upside down and cultivates.In actual production; The medium that is used for plant handstand cultivation is not distinguished with the medium of common normal use mostly yet; Normally in a kind of matrix, add the required various fertilizer that comprise trace element of plant; Wherein also be no lack of and add other fertilizer, spacetabs type (compound) fertilizer, the medium that promptly stands upside down and cultivate after it is mixed as plant through specially treated (like fermentation process).Two technical problems that such medium causes when standing upside down cultivation for solution is above-mentioned because of plant do not have desirable technique effect, even do not have effect.

The utility model content

The purpose of the utility model is exactly the deficiency to prior art, and a kind of plant culture that can solve plant root growth problem when standing upside down cultivation in the air is provided, and this medium is simple in structure, cost economy, easy to use.

For realizing above-mentioned purpose, the technical scheme of the utility model is following:

A kind of be used for plant stand upside down in the air the cultivation medium; Comprise charge cask and be contained in the matrix fill in the charge cask, it is characterized in that: there is the root system of plant mouth said charge cask lower end, and said matrix fill is divided into two-layer up and down; The upper strata is the liquid manure layer, and lower floor is the base matrix layer.

The principle of above-mentioned medium is culture medium filler is divided into two-layer up and down; And will provide the water-fertilizer nutrient of plant growing to be retained in sheaf space on the medium as far as possible, utilize the fertilizer property that becomes, the hydrotropism of plant root growth to guide root system sheaf space on medium to stretch.Geotropism that like this can appropriateness antagonism plant root growth is alleviated the plant of the plantation of standing upside down because root system all is deposited in the under-supply problem with the decline of root system absorbing capacity of liquid manure that the medium lower layer space causes.

Acting on of above-mentioned culture medium filler upper strata liquid manure layer provides required water of plant growing and nutrient, and the inducing plant root system is growth upwards.The liquid manure layer is too thick or too thin, all can not implement effectively to induce to root growth.This layer is too thin, and then moisture and fertilizer content are not enough, are not enough to produce inducing action; This layer is too thick, and then root system absorbs behind moisture and the nutrient because then no longer upwards growth of centrifugal force.The liquid manure layer can be designed as 1/4～1/3 of matrix fill total height under optimal conditions.The liquid manure layer mainly is that the plant soil-less culturing solid matrix material of using always adds the suitable base manure to the plantation plant.For the required nutrient of plant is retained in sheaf space on the medium as far as possible, in the liquid manure layer, can add water-loss reducer to improve the water binding capacity of liquid manure layer, the base manure of interpolation also can be selected slow release base manure for use.

The base matrix layer of above-mentioned medium mainly acts on the space that provides plant root growth, selects soilless culture solid matrix material commonly used for use.A small amount of nutrient that may have except that some kind host material (as cultivating soil) in the base matrix layer, do not add extra nutrient.This layer nutrient mainly come from upper strata liquid manure layer nutrient slowly under ooze.Can in the whole matrix fill of medium, form a liquid manure gradient that reduces gradually from top to bottom like this, can guarantee that root system does not lose nutrient and can induce its upwards growth again.

Compared with prior art; The beneficial effect of the utility model is: the upwards growth of root system of plant that can effectively induce aerial handstand plantation; Solve problems such as the Root Distribution that occurs in its process of growth is concentrated, piled up, growth is frail downwards, thereby guarantee the plant health growth.Medium itself is in light weight, good permeability, be easy to move, and simple, the cost economy, easy to use of product processing can extensive use in sight-seeing agriculture, courtyard greening.
