Background technology
As the nutrient source of plant growing, three kinds of main grand nutrition element nitrogen in the chemical fertilizer, phosphorus, potassium can improve the yield and quality of agricultural product greatly.Large-scale balance fertilizing of the precision agriculture that China carries out and rational application of fertilizers, its main purpose are proportioning and the fertilizing amount of confirming main nutrient elements such as rational nitrogen phosphorus potassium according to soil nutrient situation and crop.
On the one hand, China fertilizer market is main with particle fertilizer at present.Wherein, unit grain fertilizer only contains a kind of main nutrient elements, mainly contains urea, superphosphate, potassium chloride etc.Granular compound fertilizer mainly contains two-nutrient compound fertilizer (containing two kinds of element combinations in nitrogen, phosphorus, the potassium) and ternary granulated complex fertilizer material (containing nitrogen, phosphorus, three kinds of elements of potassium).Its advantage is: nitrogen, phosphorus, potassium content height, and the nutritive element kind is more, and applied once can supply crop two or more nutritive elements simultaneously.Yet also there are two major defects in composite fertilizer: 1. nutrients ratio is fixed, and is difficult to satisfy the differentiated demand of different soils and various crops.2. various nutrients movement rate in soil has nothing in common with each other, and is different by the degree of soil fixation and loss, thereby is difficult to satisfy the requirement of accurate fertilizer practice in time of application, fertilizer placement etc.
The another kind of fertilizer that development abroad is very fast: bulk blended fertilizer in bulk (Bulk Blending Fertilizer, it is fertile to be called for short BB) is a kind of complex fertilizer that several kinds of graininess are formed by single fertilizer or compound fertilizer blending according to a certain percentage.Be characterized in: 1. nutrient is comprehensive, and concentration is high, and comparing composite fertilizer can Shaoshi 40%; 2. the proportioning of nitrogen phosphorus potassium and trace element is flexible; Can adjust the blending ratio on the production line flexibly according to the different of conditions such as crop alimentary, soil fertility and yield level, remedy general universal composite fertilizer and caused the not enough or superfluous shortcoming of certain nutrient easily because of fixing nutrient proportioning.BB fertilizer can improve crops fertilisings specific aim, reduce the fertilising cost, be the ideal carrier of fertilization compositions based on earth measurement technology.Yet fertile adjustable on production line according to the proportioning blending of this BB, in case nitrogen, phosphorus after blending is accomplished, the potassium ratio is no longer adjustable.
On the other hand; Along with the cry of environmental consciousness and sustainable development of agricultural production strengthens day by day; People recognize that gradually the excessive use of chemical fertilizer can change soil structure, and then environment is damaged, and precision agriculture is widely accepted by society as feasible solution.As one of precision agriculture important content, precisely the variable fertilization technology distributes and the crop nutrition content demand difference according to soil nutrients different between the piece of small scale field, imposes the fertilizer of different quality and different proportion, thereby reduces fertilizing amount, raising utilization rate of fertilizer.Desirable variable fertilization should be according to soil nutrient situation and crop target output decision-making fertilising operation prescription; This prescription not only requires the fertilizing amount of each local area network lattice point; Also corresponding main nutrient composition should be arranged; Particularly the proportioning of nitrogen, phosphorus, potassium prescription applies fertilizer then and equips according to its gait of march and current facility position, the fertilizing amount and the proportioning of automatic time adjustment main nutrient elements.
