The preparation method is reasonable, simple and practicable in process, high in efficiency, low in application cost, simple to operate, easy to implement, convenient to use and convenient and rapid in application and has high application prospects.
Description
Technical field
The invention belongs to field of plant growing technology, more particularly it relates to an romaine lettuce 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 provides nutrition, and plant can be made can 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, has promoted agricultural production to change to industrialized production and the new stage commercially produced, has had wide market prospects.
Soilless culture replaces soil environment with the crop root environment of artificial creation, seeks mineral matter except meeting crop
Support, outside the needs of moisture and oxygen, can also manually these environment be controlled by and adjust so that product of its production without
Opinion in quantity or is better than soil cultivation 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, it is substantially reduced
Labour intensity, saves labour, improves efficiency；Additionally, soilless culture disease pest radix in overcoming because of soil
Accumulation, soil secondary salinization, soil physical and chemical property deterioration, the continuous cropping obstacle aspect that root system occurs in succession from toxicity secretion etc. has
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 from the simple high yield of pursuing in past to pursuit high yield, high-quality direction, people's demand pollution-free food
Cry is more and more higher, and under this situation, soilless culture is developed rapidly.
The development trend of modern agriculture has been complied with in vegetable aquaculture soilless culture, and the Integration of Water into Fertilizer both can save labour
Cost, can ensure again the fair supply of liquid manure in process of crop growth.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, make vegetable aquaculture greatly reduce or even stop spraying pesticide in the course of cultivation, thus realize vegetable aquaculture high yield,
The purpose of high-quality.
Cultivation technique without soil is from the laboratory research of early stage large-scale application producing till now, existing year calendar more than 100
History, applies the countries and regions of cultivation technique without soil to reach more than 100 at present in the world.Soilless culture quickly grows in China,
Numerous Research Centers production unit in one's power has carried out substantial amounts of test and has inquired into cultivation technique without soil, for advancing China to plant without 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.Current domestic widely used
Formula only has a few species such as garden examination and the rugged nutrient solution prescription in mountain of the classic water planting formula of knop, Japan, it is difficult to adapt to vegetables product
The diversity requirements of the conditions such as kind, cultivation matrix, weather and water quality, often results in fruits and vegetables soilless culture and yields poorly poor quality.
Also there is a big difference in the more developed country of China's fruits and vegetables soilless culture nutrient fluid, greatly limit cultivation technique without soil
Development.Different nutrients required for plant growth are different, and this is accomplished by the different nutrition of the characteristics design according to different plants
Liquid.
Content of the invention
Based on this, in order to overcome the defect of above-mentioned prior art, the invention provides a kind of romaine lettuce special soilless culture battalion
Nutrient solution and preparation method thereof.
In order to realize foregoing invention purpose, this invention takes techniques below scheme：

In order to the special soilless culture nutrient fluid of the romaine lettuce checking the present invention and tradition soilless culture nutrient fluid are at cultivation romaine lettuce
On implementation result, the 4-6 month in 2015, implement test example while, select the same period romaine lettuce use knop1865 invention
Classic water planting formula (being shown in Table 2) nutrient solution carries out booth soilless culture test, line-spacing, spacing in the rows, way to manage all with test example
Soilless culture is identical.After floral leaf romaine lettuce results, the statistics strain incidence of disease, complete stool fresh weight, complete stool dry weight and plant height, contrast statistics
See table 3.
Table 2
Table 3
By test example and comparative example it is found that floral leaf romaine lettuce is entered by the romaine lettuce soilless culture nutrient fluid of the employing present invention
Row soilless culture produces, and the complete stool fresh weight of its economical character index, complete stool dry weight and plant height are not only of the same race than conventional field production
Floral leaf romaine lettuce to promote far away, there has also been than the nutrient solution using tradition water planting formula and is obviously improved, and uses the present invention's
The lower floral leaf romaine lettuce strain incidence of disease of leaf vegetables soilless culture nutrient fluid cultivation is farther far below conventional greenhouse cultivation with traditional water planting, fills
Defend oneself and understand that the nutrient solution soilless culture floral leaf romaine lettuce of the employing present invention can significantly improve yield, promote quality, and can be big
Improve greatly the immunity of floral leaf romaine lettuce, reduce the incidence of pest and disease damage, thus greatly reduce spraying of agricultural chemicals, reduce
Cost, improves the economic well-being of workers and staff of vegetable grower.
Embodiment described above only have expressed the several embodiments of the present invention, and it describes more concrete and detailed, but simultaneously
