Description
Technical field
The present invention relates to the technical field of utilizing of alkaline residue, is a kind of method of preparing the organic siliceous fertilizer of high efficiency composition with alkaline residue specifically.
Background technology
At present, the kind of siliceous fertilizer mainly contains solubility in citric acid siliceous fertilizer, the large class of water-soluble siliceous fertilizer two, solubility in citric acid siliceous fertilizer refers to water insoluble and is dissolved in the siliceous fertilizer that can be absorbed by plants after acid, the common waste steel slag that mostly is steelworks, flyash, ore process through high-temperature calcination technique etc., large (every mu of 25-50 kilogram of left and right) of general amount of application, be applicable to doing soil base and execute, market price lower (hundreds of per ton unit to thousands of units not etc.); Water-soluble siliceous fertilizer refers to the water-soluble siliceous fertilizer that can directly be absorbed by plant, farm crop are higher to its absorption rate, for pyrochemistry is synthesized, production technique is more complicated, cost is higher, but amount of application is less, is generally commonly used for foliage-spray, rushes and execute and drip irrigation, also can carry out Ji Shi and imposing, concrete consumption can be liked the scarce silicon situation of silicon situation, local soil and the concrete content of siliceous fertilizer is determined according to crop varieties.
Siliceous fertilizer in the developed countries such as Japan, Korea S, Korea, the U.S., Australia, Philippines, India, Thailand, Malaysia and China Taiwan and area by spread and use, it is reported, the effect of increasing production of siliceous fertilizer on paddy rice exceeded phosphate fertilizer and potash fertilizer.China's the mid-1970s siliceous fertilizer that begins one's study, the later stage eighties is just realized suitability for industrialized production.In recent years, China in Henan, Shandong, Zhejiang, Anhui, Hubei, Guangxi, Hainan, Hebei, Sichuan etc. economize happiness silicon crop and scarce tripoli earth Applying silicon fertilizer, its amount of increase in production is: increasing production of rice 10%-20%, wheat increase yield 10%-15%, peanut yield increasing 15%-35%, soybean yield-increasing 10%-20%, sugarcane production-increasing 10%-25%, corn yield increasing 12%-20%, sesame increases production more than 15%, Yield Increase In Cotton 10%-15%, crudefiber crop volume increase 10%-25%, bamboo class volume increase 10%-20%, vegetables volume increase 15%-20%, strawberry volume increase 30%-50%, increasing yield of water melons 10%-25%.Can improve the quality of product, as the sugar degree of apple, tinctorial yield, storage tolerance and transportation etc. are all improved simultaneously.
Liquid soluble glass contains water-insoluble impurity, forms alkaline residue when to liquid soluble glass refining filtering.If alkaline residue arbitrarily abandons, will cause serious environmental pollution; Alkaline residue is carried out to harmless treatment, need to drop into a large amount of funds and manpower and materials.And the main component of alkaline residue is the solubility in citric acid such as Calucium Silicate powder, pure aluminium silicate silicate, also contain the residual water-soluble metasilicate of part simultaneously, these compositions all can be absorbed by plant, therefore alkaline residue can directly be used as siliceous fertilizer, but because alkaline residue is muddy or bulk more, use inconvenience, and the effect of directly using is also poor, therefore at present by alkaline residue as siliceous fertilizer seldom, also without any about utilizing alkaline residue to prepare the record of the method for composite organic fertilizer.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, technical problem to be solved by this invention is to provide a kind of method of preparing the organic siliceous fertilizer of high efficiency composition with alkaline residue, both can reduce environmental pollution, can reach again the object of waste ' s reclamation, improve Business Economic Benefit.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is:
A method of preparing the organic siliceous fertilizer of composite highly effective with alkaline residue, comprises the following steps:
Step 1, liquid soluble glass is filtered to the alkaline residue obtaining, and to be ground into after drying powder for subsequent use, plant residue shredded for subsequent use;
Step 2, step 1 gained alkaline residue powder is mixed with saltpetre, calcium superphosphate;
Step 3, in step 2 gained mixture, add animal excrement to mix, then add step 1 gained plant residue fragment to mix, be then placed in composting decomposition under sunshine condition, obtain the organic siliceous fertilizer of composite highly effective.
The inventive method and the organic siliceous fertilizer of prepared composite highly effective, have the following advantages:
(1) get rid of the pollution of alkaline residue to environment, saved the required a large amount of production costs of alkaline residue harmless treatment, alkaline residue is recycled, when meeting environmental requirement, improved the economic benefit of enterprise;
(2) production process is simple to operation, and raw material is easy to obtain, and production cost is low;
(3) prepared siliceous fertilizer is mainly made up of plant residue, animal excrements and alkaline residue, containing poisonous or objectionable impurities, not free from environmental pollution;
(4) prepared siliceous fertilizer is for ease of packing, the solid granular that transports and use, overcome the shortcoming that alkaline residue cannot granulation, can directly use without processing in addition;
(5) prepared siliceous fertilizer contains abundant organic matter and mineral substance, is easy to absorbed by cropsly, and amount of application is few, and fertilizer efficiency is high, and crop is had to good effect of increasing production;
(6) prepared siliceous fertilizer is slight alkalinity, and pH value, between 7 ~ 9, both can be used for the improvement of acid soil, can not burn out because alkalescence is excessive again farm crop, can effectively improve the fertility of soil;
(7) prepared siliceous fertilizer using method is various, both can be applicable to crop and has particularly liked that execute the morning of silicon crop or base is executed, and also can be used for imposing, spreads fertilizer over the fields, sprays or base is executed, and also can be used for seed soaking, is stained with root or sprinkling in the critical period of crop growth;
(8) be easy to promote, there is market application foreground widely.
In order further to optimize the present invention, the inventive method comprises the following steps:
Step 1, liquid soluble glass is filtered to the alkaline residue obtaining, and to be ground into after drying powder for subsequent use, plant residue shredded for subsequent use;
Step 2, by step 1 gained alkaline residue powder with saltpetre, calcium superphosphate according to 30 ~ 70: 10 ~ 30: 10 ~ 40 weight proportion mixes;
Step 3, to adding in step 2 gained mixture animal excrement to stir 10 ~ 60min, add again step 1 gained plant residue fragment to mix, the weight proportion of described mixture and animal excrement, plant residue fragment is 20 ~ 30: 20 ~ 30: 40 ~ 50, then be placed under sunshine condition composting decomposition 1 ~ 30 day, obtain the organic siliceous fertilizer of composite highly effective.
In order further to optimize the present invention, the order number of described alkaline residue powder is 4 ~ 60.
