A kind of vegetable soilless-culture nutrient solution and preparation method thereof

Technical field

The invention belongs to cultivation technique without soil field, be specifically related to a kind of vegetable soilless-culture nutrient solution and preparation method thereof.

Background technology

Vegetables, refer to and can cook, cook and become food, the other plant except grain is one of requisite food in people's diet.Vegetables can provide the necessary multivitamin of human body and mineral substance.Ascorbic 90%, the vitamin A of needed by human 60% from vegetables.In addition, in vegetables also have diversified phytochemicals, be people generally acknowledge to the effective composition of health.Because planting benefit is high, growing vegetables has become the new industry that China rural area develops rapidly.Along with progressively expanding of China's Vegetable produce scale and improving constantly of plantation level, and the specification of quality of human consumer to vegetable products is more and more higher, and vegetables industry is gradually to pollution-free food future development.

Soilless culture refers to the cultivation technique replacing soil cooperation nutritive medium to use with other media.Problem in the conventional soil cultivations such as soilless culture can effectively solve soil secondary salinization, nutrition is difficult to regulate and control, production work is heavy, and the nutritive ingredient needed for plant-growth can be effectively provided, the resources such as Economization on land, water, fertilizer, agricultural chemicals, improve output and the quality of plant greatly.Along with people improve constantly environmental protection consciousness, the utilization of the Nonrenewable resources such as similar quartz sand, vermiculite, peat soil, perlite, plastics is also reducing gradually, finds and develop new resources that are renewable, organic ecological more and more to receive publicity.Soilless culture, due to clean environment, the advantage such as product is pollution-free and grow, product are of fine quality, look delicate flavour is beautiful, plays important promoter action to the development of pollution-free vegetable.Nutritive medium commercially available is at present all diluent, and in use, larger change can occur each interionic balance, and how producing a kind of nutritive medium that vegetables high-quality grows fast that promotes, is the technical problem to be solved in the present invention.

Summary of the invention

In order to solve preservation capacity of water and fertility difference and not easily fix the problems such as root system, the object of the present invention is to provide a kind of vegetable soilless-culture nutrient solution, rationally, with low cost, output is high, and product are of fine quality for formula.

The technical scheme that the present invention takes is:

A kind of vegetable soilless-culture nutrient solution, it is characterized in that, in every premium on currency, the content of compound is by mg/L, its composition and proportioning as follows:

Saltpetre 5-7, ammonium nitrate 7-9, potassium primary phosphate 4-6, primary ammonium phosphate 2-4, disodium ethylene diamine tetraacetate 0.5-0.7, magnesium sulfate 0.2-0.4, chelated iron 0.04-0.07, micro-0.06-0.08, boric acid 2-4.

2, a compound method for vegetable soilless-culture nutrient solution, is characterized in that, comprises the steps:

(1) mother liquor processed: the composition got in raw material according to weight proportion is water-soluble, be made into concentration 120-140 concentrated solution doubly, room temperature storage is for subsequent use;

(2) ferment: after fresh cotton seed hulls and vegetable mould are pulverized respectively, according to volume ratio 2:1 mixing, add 25-30kg cake fertilizer in mixture per ton, stir, plastic covering film fermentation 6 months;

(3) nutraceutical matrix is joined: the liquid and the fermentation materials mixing that mother liquor are diluted with water to 1000-1500 times, fully stir, the pH value regulating matrix is 7-7.5.

The mixture that above-mentioned trace element is made up of according to mol ratio 2:1:1 magnesium sulfate heptahydrate, manganous sulfate, cupric sulfate pentahydrate.

Useful effect of the present invention is:

Containing abundant organic matter in the cotton seed hulls become thoroughly decomposed in the present invention, there is the effect of certain slow release long-acting fertilizer, rationally, pH value, close to neutral, provides the nutritive element needed for vegetable growth to formula, ionic concn not easily changes, and effectively can fix root system of plant, production operation is easy, with low cost, the soilless culture output of vegetables is high, and product are of fine quality.
