Abstract
The nutritive type acid soil improving agent is a mineral mixed fertilizer containing secondary and trace elements of calcium, magnesium, sulfur, boron and zinc, etc. and possesses double functions of improving acid soil and supplying secondary and trace elements for crops, its total content of secondary and trace elements is greater than or equal to 40%, zeolite content is greater than or equal to 20%. It is a white or greyish white powder (screened with 100-mesh sieve) alkali (pH value is above 8.5 slightly water-soluble or citrate-soluble fertilizer applicable to all crops which are grown under the condition of below pH 5.5 and deficient in secondary and trace elements.
Description
The present invention is in a kind of calcic, magnesium, sulphur, zinc, the boron etc., the mixed mineral alkaline fertilizer of micronutrient element and soil improvement agent, wherein calcium, magnesium, sulphur, zinc, boron total content 〉=40%, soil improvement agent (mainly being zeolite) content 〉=20%.Can artificially adjust mineral composition ratio of the present invention as required, promptly determine wherein mineral composition and ratio according to soil acidity, nutritional deficiency kind and nutritional deficiency degree.The present invention is fit to be applied to and is grown in below the pH5.5, and in lacking, all farm crop of trace element, its effect of increasing production can reach 8-15%.
The geographic most of soils of China's tropical and subtropical zone reacts acid, and the anthropogenic soil of Guangdong Province's peracid just has 1,053 ten thousand mu, and the soil of peracid also lacks simultaneously or hidden hunger in some, micronutrient element.Soil peracid or nutritional imbalance have become the obstruction factor that this area's modern agriculture continues high yield.At present, though some contain in, the foliage fertilizer of micronutrient element promotes, be fit to execute in the acid soil in, the micronutrient fertiliser kind is still more single, and costs an arm and a leg, and uses inconvenience.Since crop centering, micronutrient element an amount of with lack between scope narrower, the peasant if desired to some crop applyings that comprehensive nutritional deficiency symptom occurs now on the market sale in, micronutrient fertiliser just is difficult to get hold of its correct amount of application.In existing, micronutrient fertiliser consumption surplus, gently then waste, heavy then the underproduction or contaminate environment.Traditional habit is many with the lime acidity of improving the soil, yet, proved already that a large amount of or long-term application lime not only can cause soil compaction and form " lime harden field ", and can cause soil calcium, potassium, the ternary dysequilibrium of magnesium and cause the underproduction.Therefore, in existing, micronutrient fertiliser and acid soil improving agent all can not satisfy the modern needs that continue the high yield agricultural.
Purpose of design of the present invention be to provide a kind of have the improvement acid soil and in crop equilibration provides, the cheap slow mixed fertilizer of micronutrient element dual-use function, during the peasant can be easily be applied to peracid to it and lacks, on the soil of micronutrient element, make it to obtain to apply fertilizer preferably benefit.
Design objective of the present invention is finished as follows: as starting material, add calcium silicate powder, snake stone flour, elementary sulfur powder, boron ore powder and zinc powder etc. with zeolite powder respectively on demand in right amount, mix grinding 100 mesh sieves then.When executing it in the acid soil, part mineral wherein and the hydrogen ion in the soil react, or discharge nutrients such as calcium, magnesium, sulphur, zinc, boron lentamente by microbiological degradation, these nutrient parts are become the soil exchangeable alkali by zeolite, clay mineral and organic absorption, another part is dissolved in the soil water solution, and they all can be made for thing and absorb.Because the present invention is alkalescence (more than the pH8.5), mineral wherein dissolve in acid soil in addition needs to consume hydrogen ion, thus in the supply multiple nutrients, also suitably improved pH in soil, thus make acid soil obtain improvement.In addition, the zeolite powder among the present invention has very high cation exchange capacity, and it can strengthen the nutrient preserving capability energy of acid soil, improves nitrogen, potassium fertilizer utilization ratio.Because the present invention is made up of mineral manure, its fertilizer efficiency is slower, so its suitable amount ranges broad, the peasant grasps easily.Even use and slightly excessively also can obtain effect of increasing production equally, and can more not pollute the environment certainly to doing the deposits yields toxic action.
Application technique of the present invention is as follows:
1, suitable consumption suitable amount of application of the present invention at first depend on soil pH value and in, the deficiency extent of micronutrient element; Its less important consideration soil texture; Be the acidproof anti-fertile ability of crop once more.Should gather the soil sample assay in actual applications, understand wherein, trace element and potential acid content, determine its amount of application again.In addition, its amount of application becomes positive correlation with nitrogen fertilizer amount, crop to the amount of taking away of calcium, magnesium and the soil pH value of keeping.Common amount of application is 100-150 kilogram/mu, and the amount of application of sand lacks than clay.
2, during time of application and number of times improve soil pH value if desired and replenish, trace element, preferably holostrome spreads fertilizer over the fields prior to seeding or before the plantation, so that the present invention has time enough and soil to react.If do not execute before the plantation, can after plantation, mend yet and execute.Soil testing is that the effective ways that soil property changes behind the present invention are executed in monitoring, and therefore, application times of the present invention will be decided by the soil testing result.In general, the sandy soil application times is more than clay; The about 1-2 of validity period is used in the nonirrigated farmland, and the paddy field validity period is short.
3, the greatest factor of application position decision invention application effect is an application position, because it is the mineral mixed fertilizer of solubility in citric acid or slightly water-soluble, so it not only will fully contact with acid soil, and to there be moisture that the reaction of sweetening of the soil tart could take place.Field crop can be executed a part earlier before ploughing rake, execute remainder again after rake is good.In perennial orchard, to carry out in the cave holostrome in the time of should or expanding the cave winter before plantation and execute, can spread fertilizer over the fields the back trickle or loosen the soil other period in the tree basin.
Claims (3)
1, a kind of by soil improvement agent (zeolite) and Calucium Silicate powder, serpentine, elementary sulfur, boron rock and zinc powder form in, micro-mineral mixed fertilizer, calcium wherein, magnesium, sulphur, boron, zinc total content 〉=40%.
2, the various mineral of claim 1 all mixed 100 mesh sieves through grinding.
3, the mixed mineral of claim 1 is alkali reaction (more than the pH8.5), is white in color or the pale powder shape.
