Abstract
The invention provides liquid composite fertilizer special for acid soil and belongs to the technical field of compound fertilizer preparation. The liquid composite fertilizer is prepared from, by weight, 20-65 parts of plant ash, 20-70 parts of calcium fertilizer, 10-20 parts of liquid ammonia, 15-40 parts of nitrogenous fertilizer, 1-5 parts of magnesium fertilizer, 1-5 parts of potash fertilizer, 0.2-3 parts of cosolvent, 0.1-1 part of stabilizing agents and 40-90 parts of water. By means of the obtained fertilizer, the environment of the acid soil can be remarkably improved, and the liquid composite fertilizer is rich in nutrition, capable of effectively raising the utilization rate of the liquid fertilizer, good in flowability, high in stability, applicable to automated fertilizer application operation for a large area and capable of improving fertilizer application efficiency and has the advantages that time, labor and fertilizer are saved, and fertilizer effect is quick to achieve.
Description
Technical field
The present invention relates to a kind of acid soil dedicated liquid composite fertilizer, belong to composite fertilizer's preparing technical field.
Background technology
It is because the concentration of H+ is greater than the concentration of OH-in the soil solution that acid soil reacts acid, and the pH value of sour soil is all less than 6.5.According to statistics, about there is the arable land of 40%-50% in the whole world in acid, and most of acid soil is all distributed in temperate zone, subtropics and the torrid zone, comprises the great soil groups such as red soil, latosol, red earth, yellow earth and dry red soil.The arable land of China more than 20% is acid soil, and its distribution, throughout 14 provinces and regions, is mainly distributed in various redness or the yellow soil of the tropical and subtropical region on the south the Changjiang river, comprises red soil, red earth, latosol and yellow earth etc.The pH value of China's most area acid soil is all less than 5.5, wherein about has the soil pH value of 200,000 square kilometres of areas to be less than 5.0.By the impact of the factors such as fertilising, root system activity, acid deposition, China's soil acidification area and acidizing degree increase day by day, nearly 30 annuals of potential of hydrogen of whole nation soil have dropped 0.6 unit, and acid cultivated area rises to 20% (Zheng Min 2012) from 7%.Report that northern nonacid soil is also own through there is acidifying in recent years, has the soil pH value in major part area will be starkly lower than the soil pH mean value of the overall survey of soil before 30 years.In south China area, soil acidification is one of restriction agriculture production and the principal element affecting environmental quality.Soil low ph value can affect the physico-chemical property of soil, thus the growing of remote effect plant.Soil peracid causes soil compaction, quality sticky heavy, Soil structure is destroyed, air permeability is deteriorated, change the species diversity of soil after soil acidification, reduce nutrient availability in soil, positively charged ion runs off, make the nutrient deficiencies such as phosphorus, potassium, magnesium, molybdenum, boron, cause soil nutrient imbalance, fertility decline, thus cause crop growth bad, crop failure and deterioration in quality.
Conditioner for acidified soil mainly comprises biological modification and chemical modifying method.Biological modification keeps even improving soil pH mainly through applying organic manure (straw-returning, green manure turn over), slow down the acidification trend of soil, improve Soil structure, increase soil fertility, reduce disease and pest generation, increase crop yield and oil recovery enhancement, thus reach the object of improvement acid soil, but it still needs further research promotion at present.Chemical modifying is the original position improvement carried out in soil, and the method is simple, improvement lower cost, and can not the original structure of spoiled soil.Oneself a large amount of chemical improvement agent researchs through carrying out of China in recent years show that using modifying agent has good improved effect to promoting soil acidity or alkalinity.Acid soil improving agent mainly comprises traditional plant ash, lime, limestone powder, biomass charcoal etc. and Multifunction modifying agent as activating phosphorite powder etc., all can play good improved effect.Now for the improvement of soil, and change improvement into from simple improvement and have additional nutrients synchronous.As the Bian such as Guo and Rong clay mineral coordinates a kind of nutritive soil modifier of the mineral constituent such as middle and trace element and rare earth element development, also display has the effect regulating soil acidity or alkalinity and activating soil nutrient in the application.CN201410486043.5 describes a kind of acid soil special bio charcoal base compound organic and inorganic fertilizer, this Chemical Mixed Fertilizer is using charcoal as controlled-release material and sorbing material, mix obtained according to a certain percentage with other compositions, each composition collocation rationally, well meets the nutritional needs of plant growth; And there is slow release effect, there is higher using value.
But about in acid soil special fertilizer, there is not yet the report of liquid-type fertilizer.As everyone knows, liquid fertilizer production and transport is convenient, and is applicable to the fertilising of extensive big area, has a extensive future.Thus research and develop acid soil liquid fertilizer to be extremely necessary.
Summary of the invention
The present invention is directed to existing acid soil establishing in large scale Problems existing, provide a kind of acid soil dedicated liquid composite fertilizer, the weight part of each component is:
20-65 part plant ash, 20 ~ 70 parts of calcareous fertilisers, 10-20 liquefied ammonia, 15-40 part nitrogenous fertilizer, 1 ~ 5 part of fertiliser containing magnesium, 1 ~ 5 part of potash fertilizer, 0.2 ~ 3 part of solubility promoter, 0.1 ~ 1 part of stablizer and 40 ~ 90 parts of water.
Described calcareous fertilisers are one or more in calcium superphosphate, sugar alcohol calcium, calcium chloride.
Described nitrogenous fertilizer is one or more in ammonium chloride, ammonium nitrate, urea.
Described fertiliser containing magnesium is one or both in magnesium sulfate, magnesium chloride.
Described potash fertilizer is one or more in Repone K, potassium sulfate, plant ash, kainite.
Described solubility promoter is one or more in Sodium Benzoate, sodium salicylate, ethanamide, ethanol, glycerine, propylene glycol, polyoxyethylene glycol, four water eight Sodium Tetraboratees, EDTA.
Described stablizer is one or more in humic acid, clay, attapulgite.
The invention has the beneficial effects as follows:
The fertilizer of gained of the present invention significantly can improve the environment of acid soil, and it is nutritious, effectively can improve the utilization ratio of liquid fertilizer, good fluidity, stability are high, be applicable to the automatization fertilising operation that area is larger, fertilising efficiency can be significantly improved, have save time, saving of labor, the advantage such as province is fertile, fertilizer efficiency is fast
