Abstract
The invention discloses a nutrient solution for vegetable soilless cultivation. The nutrient solution is composed of the following components: potassium nitrate, magnesium sulfate, nutrients, ammonium dihydrogen phosphate, calcium nitrate, zinc sulfate, citric acid, lipid membrane emulsion and trace elements. The nutrient solution for vegetable soilless cultivation disclosed by the invention has the advantages that: according to an absorption law of leafy vegetables hydroponics on the nutrient elements, the nutrients and the trance elements are used to meet nutrition demand of leafy vegetables in a balanced manner, and the cultivation cycle can be shortened, so that the yield is improved, the contents of nitrate and nitrite in vegetables are reduced, and pollution-free crops are guaranteed. Citric acid is added to stabilize the property of nutrition liquid, the nutrient solution can maintain effectiveness in a relatively long period, and a desirable effect is reached, so that a large amount of labor force and production cost can be saved.
Description
Technical field
The present invention relates to a kind of nutritive medium, particularly relate to a kind of vegetable soilless culture nutritive medium.
Background technology
In life, leafy vegetable is wide in variety, nutritious, deeply likes by human consumer, and therefore, the cultivation amount of leafy vegetable is large, takies farmland many, consumes human and material resources more, and development leafy vegetable cultivation technique without soil is inevitable trend.
At present, domestic vegetable soilless-culture nutrient solution formula is all generally prepare for a certain vegetables, is referred to as tailored version nutritive medium, and needs for different sorts vegetables the nutritive medium configuring corresponding formula.If need production various vegetables in vegetable soilless culture process, then need the nutritive medium configuring multiple tailored version formula, complex procedures, operation easier is large, and production cost is high.When cultivating various vegetables in a region of agriculture Tourism Garden of Ecological, if share a nutrition liquid pool, so tailored version business liquid formula just cannot meet cultivation requirement.
Therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The invention provides a kind of vegetable soilless culture nutritive medium.
The technical solution used in the present invention is:
A kind of vegetable soilless culture nutritive medium, this nutrient solution prescription consists of the following composition: saltpetre, magnesium sulfate, nutrient substance, primary ammonium phosphate, nitrocalcite, zinc sulfate, citric acid, high fat film emulsion and trace element.
Preferably, it is respectively according to parts by weight:
Saltpetre 70-80 part;
Magnesium sulfate 60-65 part;
Nutrient substance 10-12 part;
Primary ammonium phosphate 20-25 part;
Nitrocalcite 30-35 part;
Zinc sulfate 12-15 part;
Citric acid 1-5 part;
High fat film emulsion 3-4 part;
Trace element 3-6 part.
Preferably, described trace element is configured by boric acid, ammonium molybdate and seven brochantites and forms, and its ratio is 1:1:2.
Preferably, described nutrient substance is configured by vinegar, sugar and calcium superphosphate and forms, and its ratio is 4:3:2.
The invention has the beneficial effects as follows: according to the absorbing rule of leafy vegetable water planting to nutritive element, balance employs nutrient substance and trace element, meet the nutritional need of leafy vegetable, and can cultivation period be shortened, improve output, reduce nitrate, the nitrite content of vegetables, ensure that crop is nuisanceless; By adding citric acid, making nutritive medium stable in properties, its validity can be kept within the long term, reaching desirable effect, a large amount of manpower and production cost can be saved.
