Abstract

The invention discloses a suspension fertilizer containing magnesium oxide or zinc oxide or a mixture of the magnesium oxide and the zinc oxide and a preparation method of the suspension fertilizer, and relates to the technical field of fertilizers. The suspension fertilizer comprises magnesium oxide, zinc oxide, a dispersing agent, a urea nitramine solution, polyol, a wetting agent, an anti-freezing agent, a defoaming agent, salad oil, rhamnolipid, a thickening agent, a high-molecular polymer, humic acid and diatomite, the finally formed suspension fertilizer is relatively high in concentration and low in cost, the particle size does not need to be ground by a sand mill, and the storage stability is improved. The production cost is greatly reduced, the fertilizer has good popularization and application prospects, the fertility is enhanced, and the fertilizer efficiency time can be prolonged, so that the loss of agricultural fertilizer is reduced, the effects of improving the soil quality and increasing the crop output value are achieved, and in addition, an oily protective film can be effectively formed on the surface of fertilizer particles when the fertilizer is used. Therefore, the purpose of preventing the fertilizer from caking is achieved, the quality of the product is improved, and the normal growth of crops is guaranteed.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a magnesium oxide and zinc oxide suspension fertilizer and a preparation method thereof. Background technique [0002] With the development of modern facility agriculture, the promotion and application of pipeline fertilization technology, drip irrigation and sprinkler irrigation and fertilization technology have begun to popularize in our country, and the application of this technology must be realized by dissolving fertilizer in water, and more and more farmers are giving crops In the process of topdressing, fertilizers are dissolved in water and then applied. At the same time, compound fertilizers are more and more widely used. [0003] However, the current liquid fertilizers containing magnesium and zinc mostly use magnesium sulfate and zinc sulfate as raw materials, which has great shortcomings and defects, mainly in the following aspects: [0004] 1. The concentration ...
