Description
Technical field
A kind of the invention belongs to field of plant growing technology, more particularly it relates to Chinese cabbage special soilless culture battalion
Nutrient solution and preparation method thereof.
Background technology
Soilless culture refers to without natural soil cultivated plant, and utilizes the battalion containing growth and development of plants institute indispensable element
Nutrient solution is providing nutrition, and plant can be enable to normally complete the planting technology of whole life cycle.It changes 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, the new stage transformation having promoted agricultural production to industrialized production and having commercially produced, there is wide market prospect.
Soilless culture replaces soil environment with the crop root environment of artificial creation, except meeting crop, mineral is sought
Support, outside the needs of moisture and oxygen, can also manually these environment be controlled by and adjust, so that product of its production is no
By being better than soil cultivation in quantity or from quality；Soilless culture broken away from 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 produces, 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 aspects that in succession occur such as toxicity secretions
Prominent effect, has the incomparable advantage of other many soil cultivations.In recent years, constantly carrying with people's living standard
Height, agricultural production develops to pursuit high yield, high-quality direction from the simple pursuit high yield in past, 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 both can save labour force
Cost, can ensure the fair supply of liquid manure in process of crop growth again.And, protecting field soilless culture combines certain ecology and prevents
Control measure, can effectively stop infecting of external source pest and disease damage, greatly reduce vegetable aquaculture pest and disease damage in growth course
Occur, so that vegetable aquaculture is greatly reduced in the course of cultivation or even prevent spraying pesticide, thus realize vegetable aquaculture high yield,
The purpose of high-quality.
Cultivation technique without soil is from the laboratory research large-scale application producing till now of early stage, existing year calendar more than 100
History, the countries and regions of application cultivation technique without soil have reached more than 100 in the world at present.Soilless culture quickly grows in China,
Production unit has carried out substantial amounts of test and has inquired into cultivation technique without soil in one's power for numerous Research Centers, plants for propulsion China no soil
The development of training cause is made that extremely valuable research, but a lot of technology 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.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 result in fruit and vegerable soilless culture and 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.

The effect test of the special soilless culture nutrient fluid of Chinese cabbage of the test example present invention
The 8-10 month in 2015, the Chinese cabbage soilless culture nutrient fluid using the present invention is carried out in vegetable growing experimental field booth
Chinese cabbage soilless culture test, experimental cultivar is white 58 in being.Seed is sterilized to be sowed after August in 2015 on the 16th, rough leaf
The plastic box of the nutritional solution in the embodiment of the present invention 1 preparing equipped with 20L for the consistent Seeding planting will be grown when fully deployed
In, 15 plants of every case, change one time of nutrition liquid weekly, and continuously ventilate.When Chinese cabbage harvests, statistics strain sickness rate, Herb fresh weight, complete
Plant dry weight and plant height.
In same period selection, white 58 carry out booth conventional cultivation, and line-spacing, spacing in the rows, way to manage are all identical with soilless culture.In vain
After dish harvests, statistics strain sickness rate, Herb fresh weight, Herb dry weight and plant height, contrast statistical result is shown in Table 1.
Table 1
The soilless culture nutrient fluid of the comparative example present invention and the effectiveness comparison of traditional soilless culture nutrient fluid
In order to check the special soilless culture nutrient fluid of the Chinese cabbage of the present invention and traditional soilless culture nutrient fluid in cultivation Chinese cabbage
On implementation result, the 8-10 month in 2015, implement test example while, the same period select in white 58 adopt knop1865 invention
Classic water planting formula (being shown in Table 2) nutritional solution carry out booth soilless culture test, line-spacing, spacing in the rows, way to manage are all and test example
Soilless culture identical.After Chinese cabbage harvests, statistics strain sickness rate, Herb fresh weight, Herb dry weight and plant height, contrast statistical result is shown in
Table 3 below.
Table 2
Table 3
By test example and comparative example it is found that being carried out using the Chinese cabbage soilless culture nutrient fluid centering white 58 of the present invention
Soilless culture produces, during the Herb fresh weight of its economical character index, Herb dry weight and plant height are not only of the same race than conventional field production
White 58 will much be lifted, and are obviously improved than being there has also been using the nutritional solution of traditional water planting formula, and adopt the Chinese cabbage of the present invention
The lower Chinese cabbage strain sickness rate of soilless culture nutrient fluid cultivation farther far below conventional greenhouse cultivation with tradition water planting, absolutely prove
Yield, lifting quality can be significantly improved using the nutrient solution soilless culture Chinese cabbage of the present invention, and Chinese cabbage can be substantially increased
Immunity, reduce the incidence rate of pest and disease damage, thus greatly reducing spraying of pesticide, reducing cost, improve vegetable grower
Economic well-being of workers and staff.
