Abstract

한종류 이상의 금속 착물을 함유하는 비닐 수지를 함유하는 분해성 피막으로 피복된 신규 입상 비료.A novel granular fertilizer coated with a degradable coating containing a vinyl resin containing at least one metal complex.

본 발명의 비료의 용해기간은 어떤 지배에서도 급격히 변화하지 않으며 비료성분이 용해된 후에 피막은 자연환경 조건하에서 퇴화 및 분해된다.The dissolution period of the fertilizer of the present invention does not change rapidly under any control, and after the fertilizer component is dissolved, the film degrades and decomposes under natural environmental conditions.

Description

분해성 피막으로 피복된 입상비료Granular fertilizer coated with degradable coating

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에서 바람직한 피막 장치중의 하나를 나타낸다.1 shows one of the coating apparatuses preferable in the present invention.

제2도는 본 발명의 실시예 및 비교예에서 퇴화 및 분해 시험을 위해 유리온실에 배치된 환 강도의 변화를 나타낸다.Figure 2 shows the change in ring strength placed in the glass greenhouse for the degradation and degradation tests in the examples and comparative examples of the present invention.
