Description
Technical field
The invention belongs to field of plant growing technology, more particularly it relates to a kind of special soilless culture battalion of Caulis et Folium Brassicae junceae
Nutrient solution and preparation method thereof.
Background technology
Soilless culture is referred to without natural soil cultivated plant, and utilizes the battalion containing growth and development of plants institute indispensable element
Nutrient solution can enable plant to normally complete the planting technology of whole life cycle providing nutrition.It is changed from ancient times
Since agricultural production depend on this traditional planting habit of soil, greatly promoted the flourishing of modern agriculture science and technology to send out
Exhibition, has promoted agricultural production to industrialized production and the new stage commercially produced transformation, with wide market prospect.
Soilless culture replaces soil environment with the crop root environment of artificial creation, and mineral is sought except meeting crop
Support, outside the needs of moisture and oxygen, can also manually these environment are controlled by and are adjusted so that its product for producing without
By being better than soil cultivation in quantity or from quality；Soilless culture broken away from it is heavy in soil cultivation dig, whole furrow,
The labout processes such as weeding, and mechanization or automation mechanized operation have been done step-by-step in whole soilless culture production, substantially reduce
Labor intensity, saves labour force, improves labor efficiency；Additionally, soilless culture disease pest radix in overcoming because of soil
Accumulation, soil secondary salinization, soil physical and chemical property deterioration, root system has from the continuous cropping obstacle aspect that toxicity secretion etc. occurs in succession
Prominent effect, with the advantage that other many soil cultivations are incomparable.In recent years, constantly carrying with people's living standard
Height, agricultural production develops from past simple pursuit high yield to high yield, high-quality direction is pursued, people's demand pollution-free food
Cry more and more higher, under this situation, soilless culture is developed rapidly.
The development trend of modern agriculture has been complied with vegetable aquaculture soilless culture, and the Integration of Water into Fertilizer can both save labour force
Cost, can ensure the fair supply of liquid manure in process of crop growth again.And, protecting field soilless culture is anti-with reference to certain ecology
Measure is controlled, infecting for external source pest and disease damage can be effectively prevented, vegetable aquaculture pest and disease damage in growth course is greatly reduced
Occur, make vegetable aquaculture greatly reduce or even prevent spraying pesticide in the course of cultivation, so as to realize vegetable aquaculture high yield,
The purpose of high-quality.
Cultivation technique without soil is from the laboratory research of the early stage large-scale application in production till now, existing year calendar more than 100
History, at present in the world using the countries and regions of cultivation technique without soil up to more than 100.Soilless culture quickly grows in China,
In one's power production unit has carried out substantial amounts of test and discussion to cultivation technique without soil for numerous Research Centers, is that propulsion China plants without soil
The development of training cause is made that extremely valuable research, but many technologies in China still in small-scale demonstration phase, than state
The development of outer cultivation technique without soil also have quite poor away from.
In terms of soilless culture application technology, nutrient solution prescription is it is critical that factor.It is domestic at present widely used
Formula only has a few species such as knop allusion water planting formula, the garden examination of Japan and the rugged nutrient solution prescription in mountain, it is difficult to adapt to vegetable product
The diversity requirements of the conditions such as kind, cultivation matrix, weather and water quality, often cause fruit and vegerable soilless culture to yield poorly poor quality.
Also there is a big difference for the more developed country of China's fruit and vegerable soilless culture nutrient fluid, greatly limit cultivation technique without soil
Development.Nutrient required for different plant growings is different, and this is accomplished by according to the different nutrition of the characteristics design of different plants
Liquid.

Booth soilless culture test is carried out using the special soilless culture nutrient fluid of the Caulis et Folium Brassicae junceae, cultivated area is each 0.5 mu, 4 afternoon 55 of August
DEG C water seed soaking 0.5h, 30 DEG C of seed soaking 6h, room temperature accelerating germination, afternoon June 5 sprouts, in being seeded in polypots, August cotyledon exhibition on the 8th
Open, reveal core, August true leaf two panels on the 17th is colonized in booth in the special soilless culture nutrient fluid of Caulis et Folium Brassicae junceae of the present invention, line-spacing
30cm, spacing in the rows 20cm, after Caulis et Folium Brassicae junceae harvests, statistics Caulis et Folium Brassicae junceae individual plant sickness rate, average Weight per plant and total output.
The same period selects two Caulis et Folium Brassicae junceae kinds " leaf mustard No. 1 " and " leaf mustard No. 3 " carries out booth conventional cultivation, line-spacing, spacing in the rows,
Way to manage is identical with soilless culture.After Caulis et Folium Brassicae junceae harvests, statistics Caulis et Folium Brassicae junceae individual plant sickness rate, average Weight per plant and total output are right
1 is see the table below than statistical result.
Table 1
The soilless culture nutrient fluid of the comparative example present invention compares with the effect of traditional soilless culture nutrient fluid
In order to check Caulis et Folium Brassicae junceae soilless culture nutrient fluid of the invention with traditional soilless culture nutrient fluid on cultivation Caulis et Folium Brassicae junceae
Implementation result, in August, 2014, while embodiment 1 is implemented, the same period selects two Caulis et Folium Brassicae junceae kinds " leaf mustard No. 1 " and " leaf mustard
No. 3 ", classic water planting formula (the being shown in Table 2) nutritional solution invented using knop1865 carries out booth soilless culture test, line-spacing,
Spacing in the rows, way to manage are identical with the soilless culture of embodiment 1.After Caulis et Folium Brassicae junceae harvests, statistics Caulis et Folium Brassicae junceae individual plant sickness rate, average individual plant
Weight and total output, contrast statistical result is shown in Table 3.
Table 2
Table 3
By test example and comparative example it is found that using the Caulis et Folium Brassicae junceae soilless culture nutrient fluid of the present invention to Caulis et Folium Brassicae junceae kind
" leaf mustard No. 1 " and " leafy mustard No. 3 " carries out soilless culture production, and the individual plant weight of its economical character index and per mu yield are not only
Caulis et Folium Brassicae junceae more of the same race than conventional field production will much be lifted, and is obviously improved than there has also been using the nutritional solution of traditional water planting formula,
And adopt the lower Caulis et Folium Brassicae junceae strain sickness rate of the Caulis et Folium Brassicae junceae soilless culture nutrient fluid cultivation of the present invention farther far below conventional greenhouse cultivation with
