Abstract

The invention relates to a potash fertilizer with high water retention capacity. The potash fertilizer with high water retention capacity is formed by combining 1-20% by weight of a water-retaining agent, 0.1-5% by weight of a binder and 75-98.9% by weight of a potash fertilizer. The preparation method comprises the following steps: uniformly mixing the water-retaining agent and the potash fertilizer, conducting granulating in a granulation roller, dissolving the binder in water, spraying the binder in a mist form to enable the powder formed by mixing the water-retaining agent and the potash fertilizer to become particles, and then carrying out drying, screening and packaging. The potash fertilizer with high water retention capacity has the advantages that the potash fertilizer with high water retention capacity can be produced on a large scale, can be reserved according to customer requirements, can supplement water for crops in a water-deficient area, and provides a large amount of water resources for crops requiring a large amount of water.

Description

technical field [0001] The invention relates to the technical field of novel fertilizers, in particular to the production and application of a highly water-absorbing potassium fertilizer. Background technique [0002] The rapid development of China's agriculture has achieved world-renowned progress. With the rapid growth of agriculture, the demand for fertilizers in China's agriculture has become more and more diversified. The fertilizers used for crops in different places or different crops are also different. , with my country's agricultural progress diversification of fertilizers is an inevitable trend. Driven by this kind of multifunctional fertilizer, only the needs of crops in different places can be guaranteed. This kind of transformation is completely in line with the development trend of environmental friendliness in our country. In some dry and rainy places, this kind of fertilizer with strong water retention will store water when it rains, and it will be absorbed ...
