More particularly, this invention pertains to method of manufacturing of functionally effective organically chelated micronutrient such as zinc, copper, iron, boron and manganese. The said organically chelated micronutrients are having multiple actions such as plant nutrient and plant protection activity.
Description
Technical field
The present invention relates to effective organic chelated trace nutrient on the function (organically chelated micronutrient) and preparation method thereof.More particularly, the present invention relates to prepare on the function effectively the method for (for example, zinc, copper, iron, boron and manganese) organic chelated trace nutrient.Said organic chelated trace nutrient has multiple action, for example plant nutrient activity and plant protecting activity.
Background technology
Known different fertilizer product has characteristic separately, perhaps as plant protection, perhaps replenishes as nutrition.Be used for the additional Ru 2006101161 of nutrition and can not to crop provide protection be provided simultaneously.Known have very widely that sterilant (microbiocide (micrbicide)) is used for protective plant routinely.Yet these insects are still serious problem.Many sterilants have following serious inferior position: the toxicity to humans and animals is high, and is high relatively to the phytotoxicity of plant, and improve pest resistance.
In addition, the crop yield (especially through the Green Revolution (Green Revolution)) of steady growth in fact makes this problem complicated through consuming soil trace nutrient storehouse (soil micronutrient pool) gradually in nearly decades.Only if the adequate measures of taking, otherwise this trend also will continue.In a lot of places, be lower than their absorption to the trace nutrient of crop supply.Therefore, the task of top priority is a balance of paying close attention to trace nutrient.
In general, if the peasant only just uses trace nutrient when crop demonstrates the shortage symptom, trace nutrient lacks in symptom and output occurs just reducing before.In addition, some common farming practice cause the extensive generation of crop micronutrient shortage through the degree capable of using that reduces the trace nutrient that exists in the soil.In addition, observe the trace nutrient shortage crop has been had following influence: for example, directly or indirectly influenced output; Cause utilizing the efficient that other must plant nutrient lower, cause water application efficiency lower, weaken the ability that crop is resisted difficult condition; Contain the composition of not expecting, the risk that makes the non-nutritive trace constituent be present in edible part and the crop varieties is higher.
The fertilizer product that does not also have this two aspect of such plant-growth satisfied and plant protection to require.Therefore, proposed how to make fertilizer not only to can be used as effective nutrition but also can be used as protectant solution among the present invention to mikrobe.Therefore, the present invention proposes the solution to this problem, and has developed effective organic chelated trace nutrient on the function, and it not only significantly improves nutraceutical absorption, and significantly improves plant protecting activity.At the nutrition secure context and produce aspect the tillage method that more nutritive foodstuffs and feed perhaps be suitable for individual health, still has challenge.Therefore, the present invention has proposed solution through trace nutrient product of the present invention is provided.
