Problems solved by technology

The above-mentioned patents either do not involve the simultaneous addition of the active substance agricultural rare earth nitrate and medical stone, or only add the active substance medical stone without using agricultural rare earth nitrate; although the Chinese patent application (application number 01131463.X) published in September 2001 It involves active substances such as rare earth nitrate and medical stone for agricultural use, but because it is only applied to crop wheat, in terms of the proportion of the formula, the content of phosphorus in the three elements of nitrogen, phosphorus and potassium is relatively high, and because wheat is more sensitive to the trace element manganese , the addition of manganese in wheat fertilizer is also high, while the content of zinc is low

Abstract

The high-efficiency special fertilizer contains N, P and K, as well as Zn, Mn, Fe, B and other trace elements and added active RE matter and Chinese medicinal stone. The high-efficiency fertilizer specially for vegetable has the ingredient weight ratio of N: P2O5: K2O: Zn: Mn: Fe: B: RE: Chinese medicinal stone of 1 to0.3-0.5 to 0.4-0.6 to 0.02-0.03 to 0.01-0.02 to 0.01-0.02 to 0.005-0.01 to 0.01-0.02 to 0.01-0.02. It may be produced via common granulating process. It can provide crop with various nutrients in balance and stably to result in high yield and high quality.

Description

technical field [0001] The invention relates to a high-efficiency special fertilizer, in particular to a special fertilizer composed of nitrogen, phosphorus and potassium as main elements and added trace elements and active substances. Background technique [0002] In the past two decades, the types of fertilizers at home and abroad have changed from single-nutrient nitrogen fertilizers and phosphate fertilizers to compound and mixed fertilizers that contain nitrogen, phosphorus, potassium, zinc, copper, molybdenum and other trace elements. . And in recent years, this "universal" fixed formula product has been updated, and special fertilizers combined with different types of crops such as local grains, vegetables, and fruit trees and different soils have been developed. For example: CN1068808A discloses a compound method of high-efficiency diammonia multi-component fertilizer; CN1068301C discloses a compound method of active foliar fertilizer, the composition of which is at...
