Description
Technical field
The present invention relates to a kind of production technique for fertilizer, relate in particular to a kind of production technique of plant water keeping organic fertilizer.
Background technology
China is one of 13 serious water shortage countries in the world, and the per capita water yield has only 1/4th of people from world average, occupies the 110th in the world.There is not the nonirrigated farmland of irrigation conditions to account for 65% of cultivated area in 80%, 16 hundred million mu of arable land that the whole nation is arid, the semiarid zone accounts for area.Prolonged drought lack of water, keeping crop seedling from drought almost become the central task that these arids, semiarid zone are sowed in spring every year.From the 1991-1995 statistics, national annual area suffered from drought reaches 4.5 hundred million mu, and annual because of hundred million kilograms of arid underproduction grain 100-200, direct economic loss reaches hundred million yuan of 100-200.The water resources poorness, severe water and soil erosion; The desertification of land area is equivalent to the land area in a medium county of annual loss; Simultaneously, because agricultural produce relies on and uses chemical fertilizer in a large number for many years, cause soil compaction and depth of soil to pollute, the various grains of output, vegetables, fruit do not reach the green organic food requirement, bring harm to people are healthy, and influenced foreign exchange earning again.Because a large amount of various chemical fertilizer use and have polluted underground water He Jiang, river, lake, sea again and destroyed the eubiosis, have caused the environmental pollution vicious cycle.Eleventh Five-Year Plan in the works, country has proposed " built environment friendly type, conservation-minded society and building a New Socialist Countryside " ambitious goal.How to adopt high-and-new science and technology, realize resisting drought saving water, improve water utilization rate, reduce the chemical fertilizer consumption, the protection environment, this difficult problem is anxious to be solved.Because it is few because of consumption that water-holding agent is used in aspects such as agricultural, forestry, adopt sand, soil etc. as carrier, be difficult to operation in the practical application, influenced water-holding agent application and actual effect, rationally uniform distribution is used, and more can not adapt to extensive mechanize and use.
Summary of the invention
Goal of the invention of the present invention provides a kind of production technique of plant water keeping organic fertilizer, selecting humic acids, high-quality fermentation people, animal, poultry manure for use is that fertilizer is suitably dosed trace element or bio-bacterial manure, as the cheap carrier of water-holding agent, water-holding agent is used for this fertilizer dressing has made Multifunction water conservation preparation, successful solution the long-term for many years unsolved difficult problem of practical application water-holding agent.
The production technique of plant water keeping organic fertilizer of the present invention may further comprise the steps: the component (following component is parts by weight) that takes by weighing following parts by weight: humic acids 150-300, trace element (copper, zinc, iron, manganese, boron, molybdenum etc.) or bio-bacterial manure (root nodule bacterium, vinelandii, phosphate solubilizing bacteria, potassium solubilizing bacteria etc.) 10-30, the people, animal of fermentation, poultry manure 600-700; Above component is put into garden dish tablets press spray suitable moisture, mixing granulation also sieves the organic fertilizer particles that obtains particle φ 1-3mm; Above-mentioned organic fertilizer particles is sent in baking oven or the baking room in 150 ℃ of oven dry, and sampling detects when containing moisture≤8% described organic fertilizer particles taking-up in the drying course, and carries out regrading, obtains φ 1-3mm organic fertilizer particles; Take by weighing the above-mentioned φ 1-3mm organic fertilizer particles 780-820 part of reducing to behind the normal temperature and put into rotary drum granulator, spray water in described organic fertilizer particles surface in rolling limit, limit, making particle surface evenly all moistening is standard, send into again in the rotary drum granulator that fineness 〉=0.18mm water-holding agent 180-220 part is housed, start rotary drum granulator and carry out Cotton seeds; After water-holding agent is with a fertilizer even dressing, put into vibratory screening apparatus, sift out unnecessary water-holding agent and pour into to be equipped with in the water-holding agent rotary drum granulator and use to continuing next time; The fertilizer that dressing sieves is sent in the rotary drum granulator that wilkinite or talcum powder 20-40 part are housed, start rotary drum granulator and carry out the processing of particle anti, after wilkinite or talcum powder are fully evenly isolated fertilizer, pour vibratory screening apparatus into, sieve out unnecessary wilkinite or talcum powder, send back to be equipped with in wilkinite or the talcous rotary drum granulator and use for continuing next time; Speckling with wilkinite or talcous dressing fertilizer after will sieving sends in 150 ℃ of drying bakers or the baking room and carries out drying, in the drying process sampling detect water content and reach≤8% o'clock, take out described fertilizer and place the sampling of drying in the air under the normal temperature to the normal temperature and carry out every technical indicator and detect, qualified back quantitative package warehouse-in is finished product.
The every technical indicator such as the following table of plant water keeping organic fertilizer of the present invention:
Product appearance: greyish white or faint yellow particle

Plant water keeping organic fertilizer of the present invention had both kept original anti-drought water-retaining agent water saving 50%, economized fertilizer 30% and had improved underground disease and pest drug effect 30% characteristics of control, satisfied the agriculture production actual needs again, particularly extensive mechanization of agriculture seeding and fertilizing applies water-holding agent simultaneously, realized that the fertile evenly fusion of water-holding agent and various particle is evenly distributed, easy and simple to handle.It is carrier that water-holding agent is become people, animal, poultry manure and an amount of trace element or the bio-bacterial manure of selecting humic acids, high-quality fermentation for use with sand, native fusion as carrier, the water conservation drought resistance function is promptly arranged, the culture fertility effect is arranged again, and inexpensive, less investment, easy to use, more meet the actual requirement of China's actual conditions and peasant.
The present invention compares with using water-holding agent separately, has following advantage: utilize humic acids to have the drought-resistant water-preserving function and help raw material to reduce the water-holding agent consumption for cheapness is attached, reach drought-resistant water-preserving and reduce application cost; Utilize people, animal, the poultry manure fertilizer of cheap high-quality fermentation to be the main carrier of water-holding agent, carry out the water-holding agent Cotton seeds, be highly suitable for extensive mechanized, good mutual miscibility is arranged with other granule type fertilizer, reach blending ratio and dwindle easily evenly, improved the water-holding agent effect; Because the water-holding agent Cotton seeds further improves the preserve moisture and fertility slow release effect; Without any side effects to plant, can not cause soil pollution, and chessom is arranged, culture fertility strengthens crumb structure and forms, and helps beneficial microorganism breeding and plant root growth and grows, and can improve soil accumulated temperature, impels plant maturity to wait in advance.
The present invention can be widely used in arid, semiarid zone, is used for drought-resistant water-preserving fertilizer, and it is compared with membrane covering, sprinkling irrigation, drip irrigation technique, and the present invention has following advantage: 1, drought-resistant water-preserving, nutrient preserving capability can be good; 2, use with low cost; 3, application process is simple and easy; 4, reduce chemical fertilizer, prevent and treat underground disease and pest pesticide dosage 30%, reduced pollution, help the eubiosis soil and environment; 5, use this product and really realized " environmental friendliness, resources conservation ", meet the production requirement of green non-pollution Organic food.
