Abstract
A kind of acidity regulator that is used for soil on nursery bed for culturing rice seedlings on dry land.The present invention is to be base-material with the furfural dregs, adds the novel acidity regulator of trace elements such as a certain amount of dilute sulphuric acid and composite nitrogen, phosphorus, potassic fertilizer and zinc, manganese.This acidity regulator is applicable to neutrality and alkaline soil, can make the mud acid degree length of holding time, and has diseases prevention, getting fat, strong seedling, promotes production-increasing function.
Description
A kind of acidity regulator that is used for soil on nursery bed for culturing rice seedlings on dry land.
Dry seedling bed of rice is the modern technique of Rice Production, and the area is promoted more widely northeastward in recent years.That evidence, the bed soil of rice seedling on upland field are is acid (pH value be about 5.5 be advisable) is beneficial to seedling growth most.And the soil in quite a few rice district, the Northeast is neutral or alkaline, therefore the bed soil of dry seedling bed of rice is carried out acid adjustment and becomes a big key problem in technology.
According to investigations, agri-scientific research department and the acid adjustment material that early uses among the people are sulfuric acid, sulphur, ferrous sulfate, acetic acid or vinegar etc., are not promoted because disadvantage is more.
It is reported that since 1984, chemical plant, the north of the Changjiang River, Jilin, Jilin Province is that base-material adds the nitric acid production nitro humus acid with brown coal, produces always and use so far (not seeing written data) as acidity regulator.Heilongjiang Institute of Agricultural Sciences's clay fertilizer was developed " medium for dry breeding of seedling bed of rice soil acidity regulator " (academy of agricultural sciences, Heilongjiang Province clay fertilizer on December 21st, 1985 " about development of paddy drought seedling seedling bed regulating acid agent and applicable cases brief introduction ") in 1984, it is carrier (base-material) with coal dust, weathered coal, coal ash bits, trisodium bits, cornu cutaneum or smokestack ash etc., adds sulfuric acid and composite chemical fertilizer and forms (academy of agricultural sciences, Heilongjiang Province clay fertilizer in March, 1986 " soil on nursery bed for culturing rice seedlings on dry land acid adjustment fertilizer synergist test embodiment ").Jilin, Jilin Province institute of agricultural sciences technological development integrated plant at the beginning of 1987 " adopts industrial sulphuric acid and high year sour material; through strict art breading acidifying " and has produced " rice seedling bed soil series modulator " (this factory in April, 1987 " rice seedling bed soil series modulator working instructions "), and this series is made up of powerful acidity regulator, nutrient adjusting preparation and three kinds of preparations of conditioning mixture.Its " high carry sour material " because technical know-how, grasps as yet at present to belong to what class material, according to preliminary test with analyze, thinks that its composition is mixed by the peat composed of rotten mosses and Xylitol slag.
Have not yet to see the report that abroad adopts this type of technology.
Prove that according to scientific experimentation the size of soil pH value becomes positive relation with the sickness rate of the damping-off of rice seedling and yellow seedling diseases, when pH in soil greater than 7 the time, sickness rate is more than 60%, and when pH value during in 5.5 left and right sides, sickness rate then is 0.Therefore use damping-off and yellow seedling diseases that acidity regulator can the prevention of water rice sprouts,, then more increase soil fertility, make rice shoot healthy and strong, and then promote increasing production of rice as in acidity regulator, adding some chemical fertilizer and trace element.
The acidity regulator that the present invention developed is to be base-material with the furfural dregs, adds a certain amount of sulfuric acid and contains the novel acidity regulator that trace elements such as nitrogen, phosphorus, potassium nutrition element and zinc, manganese form.
Furfural dregs is to produce the waste residue of discharging in the furfural process, be the residue after the corn cob acid hydrolysis steams furfural, by analysis, it is moisture about 50%, humic acid about 15%, also contain organism such as Mierocrystalline cellulose, xylogen and sulfuric acid etc., therefore the present invention can improve a mud acid, and prevention rice shoot disease increases bed clay fertilizer power, seedling quality is good, helps increasing production of rice.
Production process of the present invention: after the chemical fertilizer of the furfural dregs after the airing, 60% left and right sides dilute sulphuric acid, several nitrogenous, phosphorus, potassium and the salts substances that contains zinc, manganese weighed respectively by formula rate, send into and stir in the mixing tank, pack then, put in storage.
Raw material specification and prescription (preparing one ton of finished product)
Product specification:
| Title | Specification |
| The full potassium humic acid of outward appearance granularity pH value total nitrogen and total phosphor phosphorus trace element | Sepia pressed powder 〉=20 orders≤1 3-4% 1.8-2.0% 1-1.5% 〉=8% is an amount of |
Characteristics of the present invention:
1, particle is thin, is easy to disperse, and acid adjustment is even, and a bed mud acid degree is about pH value remains on 6 in 30 days (the paddy rice bed seedlings and soil phase is 28-30 days), and the assurance rice shoot is disease-free.
2, contain more humic acids plant growth hormones and various organic matter, can promote that well developed root system rice shoot physiological function is vigorous.
3, contain acidic substance such as a certain amount of sulfuric acid in the base-material, can significantly reduce the sulfuric acid consumption.
4, use after, increased organic substance, no mineral residue helps transforming soil.
5, technology is simple, and equipment is few, and cost is low.
Therefore the acidity regulator that with the furfural dregs is base-material is the most suitable present a kind of acidity regulator.
Realize best way of the present invention:
Mode one:
1, base-material processing: with the furfural dregs airing, drop to about 35-40% to water content till, with 20 purpose sieve, macrobead base-material and impurity are discarded, the base-material after the screening is standby.
2, preparation dilute sulphuric acid: in 30 kg of water, under agitation slowly add 60 kilograms of vitriol oils, stir, drop to 70～80 ℃ to temperature after, add 0.5 kilogram of zinc sulfate and 0.5 kilogram of manganous sulfate more respectively, it is standby to inject storage tank after the stirring and dissolving.
3, allotment mixed fertilizer: 60 kilograms in calcium superphosphate 120 kg, the urea, the vitriolate of tartar that take by weighing after pulverizing, sieving are poured in the mixing tank for 30 kilograms, and be standby behind the thorough mixing.
4, preparation finished product: take by weighing 709 kilograms of standby furfural dregs base-materials, mixed fertilizer is put into mixing tank for 210 kilograms, and the dilution heat of sulfuric acid of 80 kilograms of preparations sprays, thorough mixing while take by weighing again, after mixing, is finished product.
5, finished product pack, metering, stitching, warehouse-in.
Mode two:
1, base-material processing is identical with mode one with the preparation dilute sulphuric acid.
2, preparation finished product: take by weighing 869 kilograms of standby furfural dregs base-materials, 50 kilograms of flue dusts are mixed with it, 80 kilograms of dilute sulphuric acids will having prepared again spray in batch mixing, carry out thorough mixing simultaneously, are finished product after all.
