Abstract

The invention provides an endoplasmic slow release composite fertilizer and its preparation method. According to the invention, a nanometer plant nutrition functional blended polymer is used in a high tower melting granulation process; flow deflecting mixing technology and high efficiency emulsification technology are employed to promote binding between a nanometer slow release agent and N, P and K fertilizer molecules and wrapping action of ultrafine particles; meanwhile, a compound formed by binding of the nanometer slow release agent and the N, P and K fertilizer molecules undergoes a complexation reaction with accessories of the composite fertilizer materials so as to form flowable slurry with a uniform compact anchor type network frame structure system, and the flowable slurry is subjected to spraying granulation by the high tower so as to prepare endoplasmic slow release composite fertilizer granules. The method provided by the invention overcomes the technical bottleneck problems of high additional cost of a slow release material, difficult degradation in nature, poor affinity and incapability of continuous mass production in conventional slow release composite fertilizers; the prepared endoplasmic slow release composite fertilizer can meet needs for release of fertilizer nutrients in different periods of time, improves the utilization rate of the fertilizer and reduces application and loss of chemical fertilizers and non-point source pollution to soil.

Description

technical field [0001] The invention belongs to the technical field of slow / controlled release fertilizer production, and in particular relates to an endoplasmic slow-release compound fertilizer and a preparation method thereof. Background technique [0002] Traditional chemical fertilizers play an irreplaceable role in increasing grain production and income in my country. In 2010, the amount of chemical fertilizers used in my country reached 55.62 million tons (pure nutrients), ranking first in the world, of which nitrogen fertilizer (N) was 33 million tons. Seasonal utilization rate is 35%-40%, phosphorus fertilizer is about 10%-20%, potash fertilizer is about 35%-50%, which is 10-15 percentage points lower than developed countries on average. The loss of chemical fertilizers not only causes waste of energy and resources, but also brings serious risks to the ecological environment. Therefore, improving the utilization rate of chemical fertilizers has become one of the world...
