Coconut tree BB fertilizer with macroelements, medium elements and microelements applied to calcareous soil

Abstract

The invention provides a coconut tree BB fertilizer with macroelements, medium elements and microelements applied to calcareous soil. Five fertilizer sources of monoammonium phosphate, urea, potassiumchloride, calcium-magnesium-phosphorus powder and ardealite particles are selected according to ''Cannikin Law'' and ''soil fertility classification method'' for balanced fertilization and the weak alkaline property of the calcareous soil and are prepared into coconut tree BB fertilizer with the macroelements of nitrogen, phosphorus and potassium, the medium elements of calcium, magnesium and sulfur and the microelements of iron, zinc, manganese, boron, molybdenum, chlorine and copper; by virtue of interaction among the five fertilizer resources in the improvement of the fertilizer efficiency, the fertilizing amount is reduced. According to tests, the average yield per mu of the coconuts is increased by 10% or 20% under the conditions of equal phosphorus and nitrogen in comparison with the BB fertilizer prepared by taking diammonium phosphate as a phosphorus source; and by popularizing the coconut tree BB fertilizer with high fertilizer efficiency, low cost and strong pertinence in the production, the income of farmers can be increased to a well-off level, and a new space can be opened up.

Description

technical field [0001] The invention belongs to the field of formula fertilization, in particular to a coconut 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 a...

[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

Some enterprises do not know the characteristics of chemical fertilizers very well, and use urea to mix calcium superphosphate and nitrophosphate fertilizers, causing severe deliquescence, and even hundreds of tons of deliquescence deliquescence into empty bags, causing heavy losses; second, they only pay attention to nitrogen, phosphorus, and potassium. The middle elements of calcium, magnesium, and sulfur and the trace elements of iron, zinc, manganese, boron, molybdenum, chlorine, and copper are ignored; the third is that they only pay attention to the production and preparation of BB fertilizers for bulk crops, and do not pay attention to the production and preparation of BB fertilizers for vegetables and fruit trees. Contradiction with the international market
