Description
Technical field
The present invention relates to a kind of fertilizer, particularly relate to a kind of middle micro-particle and preparation method thereof and contain the slow controlled release bulk blended fertilizer of micro-particle in this.
Background technology
At present, the slow controlled release bulk blended fertilizer kind of China is more, and the product of various material and releasing mechanism is that a hundred flowers blossom.But, the slow controlled release bulk blended fertilizer majority using in existing agricultural is to be formed by straight fertilizer or the compound manure mixture of sustained/controlled release urea and nitrogenous, phosphorus, potassium, mainly nitrogenous, phosphorus, three kinds of elements of potassium, by sustained/controlled release urea, the release of nitrogen is controlled, reach extend fertilizer efficiency, increase production, increase income, cost-saving effect.Although this fertilizer to agricultural development, improve output and save production cost and played vital role, but the element that plant growth needs is not limited in nitrogen, phosphorus, potassium, the simple nitrogen, phosphorus, potassium used in a large number can make the trace element in soil reduce gradually, directly affect the absorption of farm crop to nitrogen, phosphorus, potassium, cause the required nitrogen of farm crop, phosphorus, potassium and trace element to can not get supplementing, nutritional trouble in plant materials, causes the quality of farm crop to decline, and occurs nutritional deficiency syndromes.
In the last few years, only used nitrogen, phosphorus, potassium, and in not using, trace element plot, occurred that plant is to the assimilation effect of npk nutrient phenomenon worse and worse; High crop yield limiting factor that some area occurs namely minimum nutrient has not been nitrogen phosphorus potassium three elements, but in sulphur, zinc, boron etc., the shortage problem of trace element.Want the just necessary balance fertilizing of plant high yield, because crop is to absorb according to a certain percentage various nutrients.
In 16 kinds of nutritive elements that plant growth needs, carbon, hydrogen, 3 kinds of elements of oxygen are that crop demand is maximum, and they derive from large G&W; Nitrogen, phosphorus are mainly derived from soil, and wherein small portion nitrogen is from air; Calcium, magnesium, 3 kinds of moderate-elements of sulphur are mainly by soil supply.Iron, boron, manganese, copper, zinc, molybdenum and 7 kinds of trace elements of chlorine are mainly derived from soil.
The slow controlled release bulk blended fertilizer of prior art is owing to being mainly made up of nitrogen, phosphorus, potassium, if nitrogen, phosphorus, potassium is excessive using all, also must combine the mutual antagonistic action occurring between various nutrients: in 16 nutritive elements, outside de-carbon, hydrogen, oxygen, also need to supplement 13 kind of plant nutritive elements; But, supplement after this 13 kind of plant nutritive element due to during new plant nutrient is manured into soil with straight fertilizer separately, can cause again new antagonistic action, must cause new contradiction.Practice shows: after during these straight fertilizers are manured into soil, often show fertilizer damage and be greater than fertilizer efficiency.Although there is at present the bulk blended fertilizer that a lot of interpolations are micro-, because trace element is without chelation treatment, poor activity, after using, often fertilizer damage is greater than fertilizer efficiency; Although have through chelation treatment, improper because of selected sequestrant, or various nutrient mixing ratio is improper, causes not reaching the effect that increases crop yield and improve quality, the even generation antagonism having, causes the fertilizer damage underproduction at reduction effect of fertilizer.
Summary of the invention
The technical problem to be solved in the present invention is to provide the slow controlled release bulk blended fertilizer that a kind of activity is good, contain various trace elements.
