Description

A kind of nutritive medium reducing plant frozen injury

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of nutritive medium reducing plant frozen injury.

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 to improve to some extent to the anti-low temperature of plant and freeze injury ability simultaneously.

Therefore develop a kind of high-selenium corn, nutritious plant nutrition liquid has great importance, and for this reason, the present inventor is prepared as object with what improve existing nutritive medium, and provides a kind of nutritive medium and preparation method thereof for the anti-low temperature of plant and freeze injury ability.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of nutritive medium reducing plant frozen injury.

The present invention is achieved by the following technical solutions:

Reduce a nutritive medium for plant frozen injury, be made up of the raw material of following weight part: furfural dregs 40-44, chitosan oligomer 3-5, phosphoric acid 3-5, raise maggot 140-160, α-amylase 0.8-1.2, water glass 12-14, trypsinase 1.0-1.2, dregs of beans 55-60, rice bran 130-140, ammonium molybdate 2-3, 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 50-60 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 38-42 DEG C, is hydrolyzed after 8-10 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 dregs of beans, furfural dregs and step 2 gained in fermentation vat, add water management fermentation heap water content at 20-25%, fermentation 22-24 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 5000-5500 rev/min of centrifugal 4-5 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 chitosan oligomer, ammonium molybdate again, be heated to 60-70 DEG C, uniform stirring 40-50 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 phosphoric acid 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 350-400mT, magnetize 10-15 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.

The raw material inclusion such as multiple amino acids, unsaturated fatty acids, polyvalent alcohol of nutritive medium of the present invention by adding, the molten point of vegetable cell can be reduced when low temperature, ICW and nutritive medium is made to form hydrate, reduce cell freezing point, prevent the film fat of cell from being gel state by liquid state, reduce the impact that plant is subject to freeze injury, increase the resistance to microthermal climate, have purposes widely in fields such as agricultural, forestry.
