Description

A kind of nutritive medium improving the saline and alkaline resistance of oil use tree peony

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of nutritive medium improving the saline and alkaline resistance of oil use tree peony.

Background technology

Nutritive medium is that a kind of impurity is few, the functional type liquid that nutrient is polynary, and all have important effect at oil with in the nutritional supplementation of tree peony and soilless culture, 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 oil obtained like this tree peony nutritive medium 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 saline and alkaline resistance of oil with tree peony simultaneously.

Therefore a kind of high-selenium corn is developed, nutritious oil tree peony nutritive medium has great importance, 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 oil lifting of tree peony salinity and alkalinity resistance.

Summary of the invention

The object of the invention is exactly the defect in order to make up prior art, provides a kind of and improves the nutritive medium of oil by the saline and alkaline resistance of tree peony.

The present invention is achieved by the following technical solutions:

Improve a nutritive medium for oil tree peony saline and alkaline resistance, be made up of the raw material of following weight part: blast-furnace slag 22-25, α-amylase 1.3-1.5, ammonium molybdate 2-4, ferrous sulfate 3-4, water glass 15-18, rice bran 135-140, saltpetre 4-5, raise maggot 130-150, trypsinase 0.9-1.1, sawdust 55-65, 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 60-70 DEG C, keep being cooled to room temperature after 4-5 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 37-39 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 blast-furnace slag, sawdust 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 4500-4800 rev/min of centrifugal 5-7 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 ammonium molybdate, ferrous sulfate again, be heated to 65-70 DEG C, uniform stirring 25-35 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 saltpetre 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 380-420mT, magnetize 12-16 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 with in the antibacterial immunity of tree peony at oil.

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 oil tree peony anti-adversity.

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 oil cannot fully absorb with tree peony.

Nutritive medium of the present invention contains amino acid, oil tree peony tethelin and trace element, for raising microorganism active, accelerate organic matter decomposition, improve soil aggregate, improve utilization rate of fertilizer etc. and have good promoter action, oil multiple enzymic activity in tree peony body can be improved simultaneously, and strengthen the absorption of root system to potassium ion, maintain the sodium-potassium balance of oil in tree peony body, improve oil with tree peony to saline and alkaline resistance.
