Abstract

The invention discloses a nutrient solution used for seedling rejuvenation. The nutrient solution is prepared from the following raw materials in parts by weight: 40 to 50 parts of wheat bran, 6 to 8 parts of nanometer carbon, 6 to 9 parts of ammonium sulfate nitrate, 1.1 to 1.3 parts of alpha amylase, 12 to 15 parts of water glass, 30 to 34 parts of fulvic acid, 1 to 2 parts of an indolebutyric acid preparation, 140 to 150 parts of rice bran, 2 to 4 parts of ethylene diamine tetraacetic acid disodium salt, 90 to 100 parts of fed maggots, 0.8 to 1.0 part of trypsin and a proper amount of water. By using the nutrient solution provided by the invention to spray seedlings, the survival rate of transplanting of the seedlings, especially ancient trees, can be significantly improved; meanwhile, the nutrient solution contains a plurality of nutrient substances needed by the seedlings, so the requirements of all tree varieties in different stages for nutrition can be met; and the nutrient solution is combined with actions of a variety of enzymes and complexing action through a multi-step process, so easy absorptivity of the nutrient solution is greatly improved, and good rejuvenation effect is exerted on the seedlings which are malnourished and grows weakly.

Description

A kind of nursery stock rejuvenation nutritional solution

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of nursery stock rejuvenation nutritional solution.

Background technology

Nutritional solution is that a kind of impurity is few, and the functional type liquid that nutrient is polynary, in the nutritional supplementation and soilless culture of plant All having important effect, owing to its nutrient content is high, consumption is few, therefore has substantial amounts of on daily life and agricultural production Use.The compound method of nutritional solution is will to be dissolved in water after the mixing of multiple inorganic quick-acting water soluble nutrients and carry out in the market Dilution, and the plant nutrition liquid so obtained all has obvious defect in property balanced in nutrition and absorption rate.

Along with the gradually quickening of urban afforestation, a large amount of nursery stocks need to transplant, and the tree body being unearthed does not has enough nutrition to mend Fill, it is easy to suffer disease and weak, but on market, do not have a kind of preferable nutritional solution to prepare for the rejuvenation of nursery stock transplanting.

Therefore developing a kind of high-selenium corn, nutritious plant nutrition liquid has great importance, to this end, the present inventor It is prepared as purpose with improve existing nutritional solution, and provides the battalion of the quick rejuvenation of a kind of energy for the transplanted plantlet that vitality is weak Nutrient solution and preparation method thereof.

Summary of the invention

The object of the invention is contemplated to make up the defect of prior art, it is provided that a kind of nursery stock rejuvenation nutritional solution.

The present invention is achieved by the following technical solutions:

A kind of nursery stock rejuvenation nutritional solution, is prepared by the raw materials in: wheat bran 40-50, nano-sized carbon 6-8, ammonium sulfate nitrate 6-9, alpha amylase 1.1-1.3, waterglass 12-15, fulvic acid 30-34, indolebutyric acid preparation 1-2, Testa oryzae 140-150, ethylenediamine Tetraacethyl disodium 2-4, raising maggot 90-100, trypsin 0.8-1.0, water are appropriate.

Specifically comprising the following steps that of the preparation of described nutritional solution

(1) carry out defibrination after being mixed by weight 1:6 with deionized water by Testa oryzae, complete backward serosity adds alpha amylase, and Adding sodium hydroxide solution regulation pH value is 7.3-7.7, serosity is heated to 55-65 DEG C, is cooled to room after keeping 3-4 hour Temperature, filters to obtain Testa oryzae enzymolysis solution, standby；

(2) raising maggot is placed in boiling water kills after take out, mix by weight 1:5 with deionized water, addition sodium hydroxide Regulation liquid pH value is 7.8-8.2, adds trypsin, solution is heated to 40-42 DEG C, use gauze after hydrolyzing 8-10 hour Filter to obtain maggot filtering residue and maggot hydrolyzed solution；

(3) put in fermentation vat after the maggot filtering residue of wheat bran, nano-sized carbon and step 2 gained being mixed, add water management fermentation heap and contain The water yield, at 22-25%, is fermented 15-18 days, is taken out by fermentation materials and squeezes, isolate fermentation residue and fermentation liquid after completing；

(4) waterglass is placed in a centrifuge within centrifugal 4-6 minute, it is dehydrated with 5000-5500 rev/min, by spraying after taking-up The method being dried obtains waterglass curing powder, is mixed with step 2 gained maggot hydrolyzed solution by this powder, adds ethylenediamine tetraacetic Acetic acid disodium, ammonium sulfate nitrate, be heated to 65-70 DEG C, and uniform stirring 20-30 minute obtains chelating liquid；

(5) by after the chelating liquid mixing of step 1 gained Testa oryzae enzymolysis solution, step 3 gained fermentation liquid and step 4 gained, Huang is added Rotten acid, indolebutyric acid preparation and remaining leftover materials, filter with double gauze after stirring, the filtrate obtained be placed in magnetic In change machine, magnetize 10-12 minute under the field intensity of 450-550mT, obtain nutritional solution of the present invention.

The invention have the advantage that

By the process to Testa oryzae, obtain a large amount of protein, mineral, vitamins and other nutritious components, improve the battalion of nutritional solution Support and be worth, and play an important role in terms of the antibacterial immunity of plant.

In preparation process, the multi step strategy to waterglass can improve the silicon easy absorbability in nutritional solution, further enhancing The effect that plant stress-resistance performance is promoted by nutritional solution.

Preparation process uses the various ways such as enzymolysis, magnetization process nutritional solution, substantially increase the absorption effect of nutritional solution Rate, decreases the wasting of resources caused because plant cannot fully absorb.

Nursery stock is sprayed by the nutritional solution using the present invention, can significantly improve the transplanting survival of nursery stock especially ancient tree Rate, its multiple nursery stock desired nutritional material contained can meet each seeds in each period demand to nutrition simultaneously, and nutritional solution is through many Step process, arrange in pairs or groups multiple enzyme effect and complexing, greatly improve the easy absorbability of nutritional solution, to underfed length The faint nursery stock of gesture has preferable rejuvenation effect.
