Description
Technical field
Specifically it is exactly a kind of to contain three kinds of form nitrogens and seaweeds the present invention relates to technical field of crop cultivation
Leaf vegetables nutrient solution and its application, are particularly suited for the soilless culture leaf of the facility such as greenhouse and vinyl house and balcony household
Dish class vegetable nutrient liquid.
Background technology
Seaweeds extract from natural seaweed, for agricultural production, the large effect of major embodiment three：(1) fertilizer efficiency：In seaweeds
Containing nutritional ingredient necessary to plant and natural mineral matter, growth regulator, plant cell division and elongation can be promoted, reinforcing is new old
Metabolism, accelerates root development, improves plant to moisture and the absorbability of nutrient, improves crop quality, improves yield；(2) resist
Inverse property：The product contains various marine biomaterials, algal polysaccharides, seeweed polyphenol, oligosaccharide and iodine, and its content ratio is fitted
In, there is obvious inhibitory action to various pest and disease damages of plant；(3) environmental protection：Seaweeds are pure natural marine algae extracts, to ring
Border is pollution-free.Grain, vegetables, melon and fruit, the tealeaves produced with seaweeds, its is best in quality, without noxious material residual, meets green
Food standard.
Leaf vegetables is vegetable species necessary to China's production and living, yield greatly, but traditional soil cultivation by
In planting year after year, various soil-borne disease insect pests are on the rise.In order to maintain high yield, vegetable grower is had to by being controlled using a large amount of agricultural chemicals
Pest and disease damage, and maintain high yield using substantial amounts of instant nitrogenousfertilizer.But with the input of a large amount of quick-acting nitrogen manures year after year, soil
Structure produces change, and utilization rate of nitrogen fertilizer is substantially reduced, and fruit quality is also gradually deteriorated.In recent years, soilless culture using and sets
Applying the development of agricultural can effectively reduce the loss of soil-borne disease insect pest.But because soilless culture and industrialized agriculture dose are big and
Concentrate, fertilizer wastes serious, a large amount of instant nitrogenousfertilizers applied make often to accumulate substantial amounts of nitrate in leaf vegetables, cause leaf vegetables
Nitrate content in class vegetables is very high.Although nitrate is not endangered directly human body, it can be gone back under bacterial action
Original can both cause methemoglobinemia into nitrite, also can be combined into nitrous ammonium with amide in people's stomach and intestine, induce digestion
System canceration, so as to be detrimental to health, so that threat to life.Therefore in adopt an effective measure reduction or control leaf vegetables
The content of nitrate, improves quality of agricultural product, to protection health by with great effect.
The content of the invention
It is an object of the invention to provide a kind of leaf vegetables nutrient solution for containing three kinds of form nitrogens and seaweeds and its
Using using part nitrate nitrogen or ammonium nitrogen in amidonitrogen replacement conventional nutraceutical liquid, with reference to right in leaf vegetables breeding time
Three kinds of nitrogen sources are carried out rational proportion by the demand rule of nutrient, and add seaweeds, promote the life of leaf vegetables root system
It is long, the efficiency that leaf vegetables absorbs nutrient is improved, strengthen leaf vegetables resistance；Coordinate Weighing type automatic irrigation system simultaneously
System, can significantly improve yield simultaneously, greatly with science, efficient for leaf vegetables growth provides required nutrient
The big accumulation for reducing nitrate-based compound in leaf vegetables, improves leaf vegetables quality and edible safety well
Property.
The technical scheme adopted by the invention to solve the technical problem is that：A kind of leaf for containing three kinds of form nitrogens and seaweeds
Dish class vegetable nutrient liquid, is formulated by following component according to concentration ratio：
NO3-N：220-280mg/L
NH4-N：36-72mg/L
Acid amides state-N：24-72mg/L
P：10-30mg/L
K：150-300mg/L
Ca：80-140mg/L
Mg：20-40mg/L
S：60-120mg/L
Fe：4.0-6.0mg/L
Mn：0.4-1.0mg/L
Cu：0.01-0.05mg/L
Zn：0.04-0.08mg/L
B：0.3-1.5mg/L
Mo：0.01-0.4mg/L
Seaweeds：150-650mg/L
In leaf vegetables special nutrient fluid each the concentrating of nutrients be according in leaf vegetables growth and development process to the demand of nutrient
Obtain, respectively by urea more than technical grade, calcium nitrate, potassium nitrate, ammonium nitrate, potassium dihydrogen phosphate, potassium sulfate, magnesium sulfate,
Obtained in the compounds such as ferrous sulfate, disodium ethylene diamine tetraacetate, boric acid, manganese sulfate, zinc sulfate, copper sulphate and ammonium molybdate, sea
Algae element is extracted by natural seaweed.
A kind of application of the leaf vegetables nutrient solution for containing three kinds of form nitrogens and seaweeds, substrate culture：Using turf,
Vermiculite, the blending of perlite equal proportion are formed, and substrate culture are carried out in the container of 2-5L volumes, after leaf vegetables final singling, using weighing
Formula automatic irrigation system, when water content of substrate is less than 50% saturation moisture content, automatic irrigation nutrient solution, when water content reaches 70%
Stop irrigating during saturation moisture content, harvest within about 30-35 days；Water planting：It is generally applicable to the most of solution culture facilities for using at present, 1
Change Additional nutrient solution to ensure nutrient supply in all left and right.
The beneficial effects of the invention are as follows：Compared with prior art, the leaf for containing three kinds of form nitrogens and seaweeds of the invention
Dish class vegetable nutrient liquid, prepares simple, can be supported the use with currently widely used various agricultural facilities；With reference to Weighing type certainly
Dynamic irrigation system provides continuous, comprehensive nutrient to leaf vegetables production, can effectively facilitate leaf vegetables growth,
Reduce pest and disease damage；And the addition of amidonitrogen and seaweeds, nitrate content in leaf vegetables can be significantly reduced, improve leaf
Dish class vegetable yields and quality, solves the problems, such as that yield and quality can not get both；According to leaf vegetables different growing stage
Nutritional need, prepare different nutrient formulas, be conducive to the nutrient supply of leaf vegetables growth period；Battalion is invented using this
The leaf vegetables of Liquid cultivation, yield is high, and Nitrate in Vegetable is low, and quality is fabulous；Advanced Weighing type is utilized simultaneously
Automatic irrigation system, substantially increases utilization rate of fertilizer, and more scientific for leaf vegetables provides nutrition supply, promptly and accurately
Quantitative supply nutrition, most nutrients are absorbed and used in nutrient solution, and irrigation efficiency is even more and greatly improves；Due to science
Fertigation and the addition of seaweeds, plant rhizospheric environment health, disease resistance enhancing, therefore greatly reduce leaf vegetables disease
Insect pest, while also just reducing pesticide dosage, significantly reduces residues of pesticides, can adapt to existing various greenhouses and greenhouse, and
And can be promoted in household balcony, save labor, substantially increase production efficiency.
