Description

The nonirritant nutritive medium that a kind of soilless culture uses

Technical field

The present invention relates to technical field of fertilizers, particularly relate to the nonirritant nutritive medium that a kind of soilless culture uses.

Background technology

Nutritive medium is that a kind of impurity is few, the functional type liquid that nutrient is polynary, in the nutritional supplementation and soilless culture of plant, all have important effect, and because its nutrient content is high, consumption is few, therefore in daily life and agriculture production, has a large amount of utilizations.The compound method of nutritive medium to be dissolved in water after multiple inorganic quick-acting water soluble nutrient mixing and to dilute in the market, and the plant nutrition liquid obtained so all has obvious defect in property balanced in nutrition and absorption rate.Do not have a kind of good nutritive medium can reduce pungency to soilless cultivating flowers root simultaneously, cause easily occurring flowers root growth obstacle.

Therefore a kind of high-selenium corn is developed, nutritious plant nutrition liquid has great importance, for this reason, the present inventor is prepared as object with what improve existing nutritive medium, and for minimizing to the stimulation of flowers root nutritive medium providing a kind of soilless culture and preparation method thereof.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides the nonirritant nutritive medium that a kind of soilless culture uses.

The present invention is achieved by the following technical solutions:

The nonirritant nutritive medium that soilless culture uses, be made up of the raw material of following weight part: plant ash 45-55, dregs of a decoction 32-36, water glass 8-10, zinc sulfate 1-2, magnesium sulfate 1-2, rice bran 135-155, raise maggot 60-70, trypsinase 0.4-0.5, white sugar 4-5, α-amylase 1.2-1.4, yeast 1-2, water are appropriate.

The concrete steps of the preparation of described nutritive medium are as follows:

(1) rice bran and deionized water are carried out defibrination after 1:6 mix, complete in backward slurries and add α-amylase, and to add sodium hydroxide solution adjustment pH value be 7.3-7.7, slurries are heated to 60-65 DEG C, keep being cooled to room temperature after 3-4 hour, filter to obtain rice bran enzymolysis solution, for subsequent use;

(2) raising maggot is placed in boiling water and kills rear taking-up, mix by weight 1:5 with deionized water, adding sodium hydroxide regulates liquid pH value is 7.8-8.2, add trypsinase again, solution is heated to 32-36 DEG C, is hydrolyzed after 10-14 hour and obtains maggot filter residue and maggot hydrolyzed solution by filtered through gauze;

(3) drop into after the mixing of the maggot filter residue of plant ash, the dregs of a decoction and step 2 gained in fermentation vat, add water management fermentation heap water content at 20-25%, fermentation 14-16 days, after completing, fermentation materials is taken out and squeeze, isolate fermentation residue and fermented liquid;

(4) water glass is placed in whizzer to dewater with 4800-5000 rev/min of centrifugal 3-5 minute, water glass curing powder is obtained by spray-dired method after taking-up, this powder is mixed with step 2 gained maggot hydrolyzed solution, add zinc sulfate, magnesium sulfate again, be heated to 65-75 DEG C, uniform stirring 20-30 minute, obtains chelating liquid;

(5) after step 1 gained rice bran enzymolysis solution, step 3 gained fermented liquid and step 4 gained chelating liquid being mixed, add white sugar, yeast and all the other leftover materials again, filter with double gauze after stirring, the filtrate obtained is placed in magnetizer, under the field intensity of 520-550mT, magnetize 12-14 minute, obtain nutritive medium of the present invention.

Advantage of the present invention is:

By the process to rice bran, obtain a large amount of protein, mineral substance, vitamins and other nutritious components, improve the nutritive value of nutritive medium, and play an important role in the antibacterial immunity of plant.

The easy absorptivity of silicon in nutritive medium can be improved to the multi step strategy of water glass in preparation process, further enhancing the effect that nutritive medium promotes plant stress-resistance performance.

Use the various ways such as enzymolysis, magnetization process nutritive medium in preparation process, substantially increase the assimilated efficiency of nutritive medium, decrease the wasting of resources caused because plant cannot fully absorb.

Nutritive medium of the present invention is applicable to the use of soilless cultivating flowers, its nutrient contg is balanced, do not have and choose Ti, adding of a large amount of polysaccharide and albumen, flowers blade can be made under life-time service fertile tender glossy, and the nutrient density of nutritive medium is moderate simultaneously, and presents Chelating state and be beneficial to absorb, pungency is not had to the root of flowers, there will not be flowers bad root phenomenon.

Embodiment

Below in conjunction with following embodiment, the present invention is described in further detail:
