Calcareous soil application apricot tree BB fertilizer with major elements, medium elements and micro elements

Abstract

The invention provides a calcareous soil application apricot tree BB fertilizer with major elements, medium elements and micro elements, the apricot tree BB fertilizer has the major elements of nitrogen, phosphorus and potassium, the medium elements of calcium, magnesium and sulfur and the micro elements of iron, zinc, manganese, boron, molybdenum, chloride and copper, the apricot tree BB fertilizer is prepared from five fertilizer sources of monoammonium phosphate, urea, potassium chloride, calcium magnesium phosphate powder and phosphogysum particles according to the characteristic that calcareous soil is alkali, by use of the interaction of the five fertilizer sources for improvement of fertilizer efficiency, the application amount of the fertilizer is reduced, the price is low, the price of the calcareous soil application apricot tree BB fertilizer is 20 yuans cheaper per 50kg than that of a same content compound fertilizer on the market, and 400 yuans cheaper per ton than that ofthe same content compound fertilizer on the market, and according to garden tests, under equivalent-nitrogen and phosphorus conditions, the yield of apricot fruits fertilized by the BB fertilizer prepared from the five fertilizer sources can be increased by 10-20% per mu compared with that of the apricot fruits fertilized by a BB fertilizer prepared from diammonium phosphate as a phosphorus source.

Description

technical field [0001] The invention belongs to the field of formula fertilization, in particular to an apricot tree BB fertilizer which is applied in calcareous soil and contains a large amount of trace elements. Background technique [0002] The so-called "BB" fertilizer is the abbreviation of English Bulk Blending Fertilzer. It is mainly a kind of compound fertilizer formed by physically blending two or more single fertilizers or compound fertilizers in a certain proportion. At present, some developed countries promote the "BB" fertilizer. The area of ​​BB" fertilizer has reached more than 80%, but my country is still using traditional fertilization experience, resulting in a passive situation of using one-third of the world's chemical fertilizers to produce one-fifth of the world's grain. Under the guidance of the idea of ​​"fertilization" as "formula fertilizer application", the promotion of "BB" fertilizer area has been greatly developed, but in the process of preparing ...

[0002] The so-called "BB" fertilizer is the abbreviation of English Bulk Blending Fertilzer. It is mainly a kind of compound fertilizer formed by physically blending two or more single fertilizers or compound fertilizers in a certain proportion. At present, some developed countries promote the "BB" fertilizer. The area of ​​BB" fertilizer has reached more than 80%, but my country is still using traditional fertilization experience, resulting in a passive situation of using one-third of the world's chemical fertilizers to produce one-fifth of the world's grain. Under the guidance of the idea of ​​"fertilization" as "formula fertilizer application", the promotion of "BB" fertilizer area has been greatly developed, but in the process of preparing and producing BB fertilizer, there are still many disadvantages: First, the selection of fertilizer sources is unscientific, and the relationship between fertilizers has not been brought into play. Synergistic joint response, the so-called joint response, that is, when two or more elemental fertilizers are used in combination, the fertilizer output exceeds the sum of the yields of the single application of elemental fertilizers
