Abstract

The invention discloses a root system heat preservation coated fertilizer for nursery plants. The coated fertilizer is prepared from the following raw materials in parts by weight: 38 to 42 parts of rape seed cakes, 24 to 26 parts of beet pulp, 9 to 11 parts of chicken feather, 6 to 7 parts of diammonium phosphate, 3 to 4 parts of borax, 2 to 3 parts of calcium lactate, 1.3 to 1.5 parts of bone gelatin, 45 to 48 parts of young tangelo fruits, 0.5 to 0.6 part of dimethylformamide, 2.4 to 2.5 parts of jasmonic acid methyl ester, 1.3 to 1.6 parts of polyvinyl alcohol, a proper amount of 50 percent ethanol solution, a proper amount of 70 percent methanol solution and a proper amount of water. According to the coated fertilizer, a great number of organic matters are added to improve the granular structure of soil and enhance the heat preservation and cushioning capability of the soil on one hand, and on the other hand, the organic matters such as the chicken feature and the beet pulp are degraded along with release of heat to implement slow release of heat under multiple coating of a binding material and coated carbon powder, so that heat-preservation effects on root systems of the nursery plants are achieved, and growth of new roots and nutrition absorption of old roots are promoted.

Description

A kind of nursery stock root system is incubated coated fertilizer

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of nursery stock root system and be incubated coated fertilizer.

Background technology

Along with China plantation specialization, industrialization, the development of scale, it is constantly upgraded for the requirement of fertilizer, and conventional fertilizers is low due to plant recovery of nutrient, constrains the sustainable development of plant husbandry.The application of coated fertilizer is then the effective way solving this problem.But the coated fertilizer of current common coated fertilizer is to use the non-degradable high molecular polymer of chemosynthesis, easily remain in soil and cause soil property to degenerate and pollute, the function singleness of coated fertilizer simultaneously, generally only there is slow controlled-release effect, do not account for the effects such as water suction, antibacterial, antioxidation and the practicality for varying environment.

Containing biological active substanceies such as a large amount of flavone, Neosynephrine in Citrus young fruit, related substances is extracted from Citrus young fruit, and the material extracted added to fertilizer can improve the nutrient of fertilizer be worth, and improve the physiologically active of plant, induction raising plant resistance to environment stress, enhancing improving activity of root system, enhance metabolism etc. is all played a key effect, is therefore applied in the preparation of fertilizer that there are high potentiality.And physiological fallen fruit is a kind of normal phenomenon in citrusfruit growth course; China's citrus plants is wide in variety, cultivated area is wide; having substantial amounts of Citrus young fruit to come off before maturation every year, young fruit shedding aboundresources, this also provides the raw material of abundance for the scale extraction and application of Citrus young fruit.

CN101928189A (201010264389.2) provides a kind of sustained-release fertilizer for nursery stocks in landscaping and preparation and application.Raw material is selected different types of Controlled Release Fertilizer and utilizes multiple peplos raw material to compound, and according to the nutrient element releasing rule in soil, prepares sustained-release fertilizer for nursery stocks in landscaping.They achieve significant progress by applying of several coated fertilizers in terms of fertilizer efficiency prolongation, but based on a great number of elements such as nitrogen, phosphorus, potassium, the demand of nursery stock centering trace element can not be met very well, still need and individually supplement, add fertilising cost, corresponding adjustment cannot be made for the physiological situation of plant, soil property water source environment simultaneously.

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 root system is incubated coated fertilizer.

The present invention is achieved by the following technical solutions:

A kind of nursery stock root system is incubated coated fertilizer, is prepared by the raw materials in: rapeseed cake 38-42, megasse 24-26, chicken feather 9-11, Diammonium phosphate (DAP) 6-7, Borax 3-4, calcium lactate 2-3, osseocolla 1.3-1.5, tangelo young fruit 45-48, dimethylformamide 0.5-0.6, (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate 2.4-2.5, polyvinyl alcohol 1.3-1.6,50% ethanol solution are appropriate, 70% methanol solution is appropriate, water is appropriate.

Described nursery stock specifically comprises the following steps that with root system insulation coated fertilizer preparation method

(1) rapeseed cake, megasse, chicken feather mixing are placed in fermentation vat retting fermentation 3-4 week, after ferment, take out fermentation material drying, and with Diammonium phosphate (DAP), Borax mixing granulation, obtain granule standby；

(2) dry 48-50 hour at 50-55 DEG C after tangelo young fruit being dried, pulverize with pulverizer after taking-up and cross 180-200 mesh sieve, 50% ethanol solution is added again by solid-liquid ratio 1:30-32g/ml, and under 570-600W power the microwave extraction 38-40 second, be filtrated to get ethanol extract and filtering residue after completing, ethanol extract is evaporated powder is standby；

(3) step 2 gained filtering residue use water is rinsed to without ethanol residual, 70% methanol solution is added again by solid-liquid ratio 1:24-25g/ml, after being heated to 33-35 DEG C under the conditions of 20kHz supersound extraction 44-46 minute, be filtrated to get methanol extract liquid after completing, be evaporated powder is standby；

(4) rice husk is calcined 2-3 hour with 480-500 DEG C under closed environment, pulverize as powdered carbon after taking-up, and add the water of 5-6 times of its quality, filter after soaking 8-10 hour and remove moisture removal, and rejoin 6-8 times of water, it is simultaneously introduced step 2 gained powder, dimethylformamide, (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate and calcium lactate, is heated to 98-100 DEG C, being down to room temperature after being incubated 140-150 minute, it is standby that filtering drying obtains peplos biology powdered carbon；

(5) by step 3 gained powder, osseocolla and polyvinyl alcohol, and add the water of 2-3 times of mixture quality, be heated to 56-58 DEG C and stir to the most homogeneous, being down to room temperature afterwards, obtain binding material standby；

(6) step 1 gained granule is poured in the rotary drum of rotation, it is heated to 45-46 DEG C, and take half step 5 gained binding material to particle surface sprinkling, afterwards step 4 gained peplos biology powdered carbon is joined in rotary drum, spray residue binding material makes material roll granulating simultaneously, stop operating after to be wrapped, obtain coated fertilizer of the present invention.

The invention have the advantage that

The fertilizer of the present invention uses that rice husk powdered carbon is immobilized plants source property active substance, the utilization rate of fertilizer is improve while slowing down fertilizer nutrient rate of release, twice extraction of Citrus young fruit achieves the Neosynephrine containing it respectively, the efficient utilization of the materials such as flavone, and utilize the extract of young fruit on the one hand by causing the slight change of root cell membrane structure, suitably reduce membrane passage, thus reach to strengthen the purpose of cell membrane stability, on the other hand by the enzyme relevant with mineral nutrition or ionic pump on activated membrane, improve the selection absorbability to various nutrients, thus promote root system to the absorption of nutrient and utilization.On the one hand the coated fertilizer of the present invention utilizes a large amount of organic addition to improve the grain structure of root soil simultaneously, enhance the insulation buffer capacity of soil, on the other hand the degraded that chicken feather, megasse etc. are organic is along with the release of heat, the slow release that heat scatters and disappears is achieved under the multiple cladding of binding material and peplos powdered carbon, thus serve the heat insulation effect of seedling root, promote growth and the alimentation of old root of new root.
