Abstract

The invention discloses a preparation method of a rare earth element-rich fertilizer anti-caking agent. The preparation method comprises the following steps: preparing an anti-caking agent raw materials, heating the anti-caking agent raw materials, adding other raw materials, preparing the anti-caking agent, preparing a chemical fertilizer raw material, heating the chemical fertilizer raw material, and obtaining caking rate data. The preparation method of the rare earth element-rich fertilizer anti-caking agent adopts renewable resources such as castor oil to replace mineral oil, and adds trace rare earth elements in the preparation process, so the obtained anti-caking agent has a low cost and is friendly to the environment; the rare earth elements can improve the chlorophyll content of plants, enhance photosynthesis, promote the growth of roots and enhance the absorption of the roots to nutrients, and the rare earths also can promote seed germination, improve the seed germination rateand promote seedling growth, so the anti-caking agent also has the ability to enhance the resistance of crops to diseases, cold and drought; and the anti-caking agent is a functional anti-caking agent prepared by using plant oil as a raw material and adding some rare earth elements.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to the preparation of a rare earth element-rich fertilizer anticaking agent. Background technique [0002] In our country, chemical fertilizers are used in a large amount every year as an agricultural necessity. With the modernization of China's agriculture, our requirements for chemical fertilizers are increasing, which is mainly reflected in resource utilization and environmental protection. At present, there are still many problems in the use of fertilizers in agricultural production, such as low utilization rate of fertilizers, easy caking of fertilizers, single function of fertilizers and so on. Among them, there are many factors for fertilizer agglomeration. The internal factor is water, which is divided into crystal water and free water. Water can promote the formation of crystal bridges and fertilizer dissolution and recrystallization; external factors are mai...
