Description

A kind of nursery stock coated fertilizer with nonirrigated farmland transpiration regulatory function

Technical field

The present invention relates to technical field of fertilizers, particularly relate to a kind of nursery stock coated fertilizer with nonirrigated farmland transpiration regulatory function.

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 coated fertilizer with nonirrigated farmland transpiration regulatory function.

The present invention is achieved by the following technical solutions:

A kind of nursery stock coated fertilizer with nonirrigated farmland transpiration regulatory function, is prepared by the raw materials in: sodium thiosulfate 4-5, para-aminosalicylic acid 2.2-2.3, corn slag 45-46, distiller's grains of beer 10-12, Semen Citri Reticulatae powder 9-11, potassium dihydrogen phosphate 4-6, ferrous sulfate 2-3, calcium-base bentonite 1-2, corn starch 3-4, tangelo young fruit 43-46, dimethylformamide 1.3-1.4, (-)-methyl cis-2-pent-2'-enyl-3-oxocyclopentylacetate 2.5-2.6, polyvinyl alcohol 1.7-1.8,50% ethanol solution are appropriate, 70% methanol solution is appropriate, water is appropriate.

Specifically comprising the following steps that of the described nursery stock coated fertilizer preparation method with nonirrigated farmland transpiration regulatory function

(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 630-650W power the microwave extraction 34-36 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 3-4 hour with 380-400 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-base bentonite, is heated to 98-100 DEG C, being down to room temperature after being incubated 80-90 minute, it is standby that filtering drying obtains peplos biology powdered carbon；

(5) by step 3 gained powder, para-aminosalicylic acid, corn starch 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 40-42 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.The coated fertilizer of the present invention can preferably solve the water balance problem during the seedling growth of nonirrigated farmland simultaneously, sodium thiosulfate, para-aminosalicylic interpolation can induce nursery stock to reduce Stomatal complexes under drought condition, suppression transpiration, the use of ferrous sulfate can increase free iron content in nursery stock body, improve blade water holding capacity and Chlorophyll synthesis amount, and then by the regulation to transpiration, it is ensured that nursery stock moisture absorption and the balance scattered and disappeared, promote seedling growth.
