Tea tree BB fertilizer applied to calcareous soil and containing macro-elements, secondary elements and microelements

Abstract

The invention provides tea tree BB fertilizer applied to calcareous soil and containing macro-elements, secondary elements and microelements. The tea tree BB fertilizer containing macro-elements including nitrogen, phosphorus and potassium, secondary elements including calcium, magnesium and sulfur, and microelements including iron, zinc, manganese, boron, molybdenum, chlorine and copper is prepared by selecting six fertilizer sources including monoammonium phosphate, urea, potassium chloride, calcium-magnesium-phosphorus powder, phosphorus gypsum particles and ammonium sulfate according to abalanced fertilization Cannikin Law and a land capability classification method and according to an alkaline property of the calcareous soil; the interaction effect of improving the fertilizer efficiency of the six fertilizer sources including the monoammonium phosphate, the urea, the potassium chloride, the calcium-magnesium-phosphorus powder, the phosphorus gypsum particles and the ammonium sulfate is utilized, so that the fertilizer application amount is reduced and the price is low; a tea garden test shows that compared with BB fertilizer which is prepared by taking diammonium phosphate asa phosphorus source, the yield of tea leaves per Mu is averagely increased by 10 percent to 20 percent by applying the BB fertilizer disclosed by the invention under equal phosphorus and equal nitrogen conditions; the tea tree BB fertilizer with strong pertinence is popularized in a production process, and a new space for increasing the income of farmers and striving for relatively comfortable life can be provided.

Description

technical field [0001] The invention belongs to the field of formula fertilization, in particular to a tea tree BB fertilizer which is applied in calcareous soil and contains a large amount of medium and 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 our 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. In recent years, although under the guidance of the idea of ​​"reforming formula fertilization" to "apply formula fertilizer", the promotion of "BB" fertilizer area has made grea...

Problems solved by technology

However, some enterprises do not know the characteristics of chemical fertilizers very well. They use urea to mix calcium superphosphate and nitrophosphate fertilizers, causing serious deliquescence, and even hundreds of tons of deliquescence deliquesce 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. contradict the international market
