Description
Technical field
The present invention relates to middle trace element fertilizer technical field more particularly to a kind of middle microelement granular fertilizer and its preparation sides
Method.
Background technique
Moderate-element refers to requirement in process of crop growth inferior to nitrogen, phosphorus, potassium and the nutrition member for being higher than microelement
Element.Moderate-element typically constitutes from the 0.1%~1% of crop body dry matter, is often referred to three kinds of calcium, magnesium, sulphur elements.In traditional nutrition
In element classification, calcium, magnesium, sulphur are also often divided into a great number of elements, are primarily due to plant to the uptakes of these three elements also very
Height is more than a great number of elements sometimes, especially can be more than the absorption of phosphorus.Due to frequent in the company ion of soil and some fertilizer
Containing a large amount of calcium, magnesium, sulphur, so people often ignore these three elements to the importance of plant growth.In fact, calcium, magnesium,
Sulphur has extremely important without replaceable physiological function in plant.Calcium can stablize biofilm structure, keep the complete of cell
Whole property；Calcium is the important element for constituting cell wall, and most calcium are present in cell wall in plant.Magnesium is the group of chlorophyll
Point, it is of great significance for photosynthesis of plant.
Microelement, which refers to, accounts for organism gross mass 0.01% hereinafter, and being some elements necessary to organism.As iron,
Silicon, zinc, copper, iodine, bromine, selenium, manganese etc..Microelement is some elements that plant is required but demand is seldom.These elements exist
When lacking in soil or cannot be utilized by plant, plant undergrowth is excessive to easily cause poisoning again.In agricultural, Chang Yiwei
Secondary element makees seed treatment, foliage top dressing improves crop yield.
Data show, in national soil in calcium, magnesium, sulphur, iron, manganese, copper, zinc, boron, molybdenum etc. micronutrient levels in critical value
Cultivated area below respectively reaches 63%, 53%, 40%, 31%, 48%, 25%, 42%, 84%, 59%.It is complete with second
The data of state's overall survey of soil are compared, and the cultivated area of middle microelement deficiencies increases nearly 1 times.
In recent years, since what a great number of elements nitrogen, phosphorus, potassium fertilizer used is continuously increased, long-term high-intensitive cultivation and a large amount of speed
Imitate fertilizer application, cause agricultural land soil constructional aspect be deteriorated, Trace Elements in Soil is unbalance, soil fertility decline, crop yield and
Quality decline, so that the bitter pit of apple, the blossom-end rot of tomato and green pepper, the brown spot of potato, citrus and banana tiger fur
The physiology disease such as leaf generally occurs.However, existing secondary and micro-element fertilizers element species are single at present, validity is low, no
It can in time, comprehensively supplement crop and harvest the middle microelement taken away, thus cannot play and provide health environment for plant growth,
It is balanced nutritious, improve crop yield, the good result of improving quality.
