Abstract
A process for preparing the water-preserving biologic humic acid fertilizer for drought area includes such steps as pulverizing weathered coal, sieving, regulating water content, adding one-valence ions and its carrier and stabilizer, stirring, laying aside for 1-2 days while stirring per 6 hrs, spraying the liquid extract of fertile soil and active primer, culturing for 7 days, baking, and mixing it with urea and potassium sulfate.
Description
Technical field
The present invention relates to a kind of production method that promotes the humic acid bio-fertilizer material that the agricultural soil coacervate forms, be applicable to the area that soil organic matter content is low, soil agreegate quantity is few, to increase the ability of Soil conservation precipitation.
Background technology
The soil organism can promote the formation of soil agreegate, thereby the agricultural land soil coacervate quantity of long-term application fertilizer is more.After soil particle forms coacervate, can improve the hole situation of soil significantly, regulate the supply of soil nutrient, increase the maintenance of soil, reduce rainwash, thereby help soil conservation and agricultural land soil retaining external moisture.
Weathered coal, brown coal etc. all contain humic acid, but generally all are in and the complexing of metal ion attitude, directly are manured into soil and generally can not bring into play the effect of binder soil soil particle.Adopt physics, chemical process can activate a part of humic acid, but efficient is low, generally can only carry out in liquid, need a large amount of energy to carry out follow-up dehydration procedure, thereby cost is higher.
Utilize the characteristic such as complexing, stimulating plant growth of humic acid, be equipped with mineral manure nutrient is provided, can make humic acid fertilizer.The starting point of making this class fertilizer is to utilize the complexing characteristic of humic acid to increase some nutrient availability, and promotes plant growth by the function of its stimulating plant growth.But this class fertilizer is considered less to improving the soil water storage ability at present.
Summary of the invention
The technical problem to be solved in the present invention is to propose a kind of method of producing the humic acid bio-fertilizer material, can promote soil agreegate to form by fertilising, and nutrient is provided, and improves the soil water storage ability, accomplishes that fertilizer, water are synchronous.
The method of the invention comprises the steps:
Weathered coal is pulverized, crossed the 2mm sieve, select for use＜the weathered coal particle of 0.5mm further handles;
Regulate weathered coal particle water content to 30%, add the monovalent ion of weathered coal amount 10% and the stablizer of carrier and 20% thereof, mix, placed 1 to 2 day under the room temperature, stirred 1 time in per therebetween 6 hours;
Even sprinkling 0.01% rich soil water extract (water: soil=10: 1, dilute 100 times) and 0.1% active primer, cultivated 7 days for 20-30 ℃, dry down at 60 ℃ afterwards;
Weathered coal after the processing and urea, vitriolate of tartar are mixed and made into fertilizer.
The present invention not only can provide nutrient but also can improve the soil water storage ability by fertilising, accomplish that fertilizer, water are synchronous, be particularly useful for arid, semiarid zone, be applicable to the area that soil organic matter content is low, soil agreegate quantity is few, to increase the ability of Soil conservation precipitation.
Embodiment
In order to give full play to the effect of humic acid material in the soil agreegate forming process, reaching by fertilising not only can provide nutrient but also can improve the purpose of soil water storage ability, the invention provides a kind of new-type fertilizer, this fertilizer can not only provide suitable nutrient for plant growth, and can increase the quantity of coacervate in the soil, strengthen the water-holding capacity of soil.
The specific practice that the method for the invention adopts is:
Take the solid phase ion exchange technique, promptly be not more than under 30% condition in the weathered coal water content, with Ca2+, the Mg2+ in the monovalent ion replacement weathered coal humic acid, simultaneously by adding stablizer, make the Ca2+ that exchange, Mg2+ inactivation and no longer with the humic acid complexing, and make oven dry afterwards water-soluble humic acid ratio bring up to more than 80% of total content.
Afterwards, be material with the very high weathered coal of water-soluble content of humic acid, inoculation soil microorganisms flora has carried out the gas degraded, makes humic acid further be decomposed into less molecule.
At last, fermented material is added in inorganic nitrogen, phosphorus, the potassic fertilizer by a certain percentage, make the humic acid bio-fertilizer material that can promote that soil agreegate forms.
It should be noted last that: above embodiment is the unrestricted technical scheme of the present invention in order to explanation only, although the present invention is had been described in detail with reference to the foregoing description, those of ordinary skill in the art is to be understood that: still can make amendment or be equal to replacement the present invention, and not breaking away from any modification or partial replacement of the spirit and scope of the present invention, it all should be encompassed in the middle of the claim scope of the present invention.
