Description
Technical field
The present invention relates to technical field of fertilizers, particularly relate to a kind of many little special-purpose fertilizer of high density humic acid type chelating and working method thereof that is used for wheat.
Background technology
Wheat is one of human of paramount importance food crop, is the staple food grain of 1/3 population in the world, and in China, wheat is the second largest food crop that are only second to paddy rice, first of its cultivated area and the ultimate production Jun Ju countries in the world.
The important micronutrient element of in the wheat grain some (iron, zinc, manganese etc.) often lack or content lower; Cause the crowd of about 3,000,000,000 developing countries in the present whole world being faced with the threat of potentiality micronutrient element deficiency disease " recessive hungry "; Particularly the economically underdeveloped area has 1/3 children and women to show crucial micronutrient element deficiency disease (iron, zinc).The long-term lacking of body trace element will influence the production force level of society, increase the spending of social health care, bring heavy burden for national economy and social progress.
Fertilizer plays decisive role to the yield and quality of wheat; All kinds of compound (mixing) fertilizer that is used for wheat growth at present, the shortcoming of existence are that fertilizer nutrient is inhomogeneous, content is on the low side, weak point of fertile phase, poor dissolution, utilization rate of fertilizer are low, and single inorganic fertilizer causes soil compaction; Single fertilizer nutrient is low, fertilizer efficiency is poor; Even compound organic and inorganic fertilizer often causes fertilizer efficiency poor owing to content is on the low side, and generally do not contain the trace element that improves crop yield and quality.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of many little fertilizer specially for wheat of high density humic acid type chelating and working method thereof that improves crop anti-adversity and improve quality, replenish the required trace element of plant growth is provided.
