Water-retaining liquid suspension fertilizer and preparation method thereof

Abstract

The invention provides a water-retaining liquid suspension fertilizer and a preparation method thereof. The water-retaining liquid suspension fertilizer is prepared from, by weight, 27-29 parts of humic acid, 6-8 parts of a nitrogen fertilizer, 5-11 parts of a phosphate fertilizer, 7-8 parts of a potash fertilizer, 1-2 parts of a boron fertilizer, 0.5-1 part of EDTA-Fe, 0.5-1 part of EDTA-Zn, 0.5-1 part of EDTA-Mn, 7-10 parts of a water retention agent, 3-5 parts of tea stems, 1-2 parts of a wetting and dispersing agent, 1.6-3 parts of an emulsifier, 1-4 parts of a thickener, 0.5-1 part of a preservative and 0.5-1 of an anti-tackiness agent. The water-retaining liquid suspension fertilizer has the advantages that a large amount of elements such as the humic acid, nitrogen, phosphorus and potassium are contained, trace elements such as boron and zinc are also added in time; a water retaining agent itself has a water absorption effect, can absorb and store water when the content of soilwater is high, and can release water when the content of the soil water is low, thereby achieving the water-saving and water-retaining effects.

Description

technical field [0001] The invention specifically relates to a water-retaining liquid suspension fertilizer and a preparation method thereof. Background technique [0002] There are 42.9% of the dry land in the world. How to make the soil retain more rainfall for plants to "use immediately" is a problem facing dryland agriculture. Water-retaining agent is an important water-absorbing and water-retaining chemical that has been developed and applied for many years. However, the use of water-retaining agent alone not only increases the number of farmland operations and costs, but also due to the small amount of water-retaining agent used, it is difficult to fully contact with fertilizers, and it is difficult to absorb water. It interacts with fertilizers and affects the performance of the water retention benefits. On the other hand, my country's agricultural water consumption accounts for about 80% of water resource consumption. However, the global water resource crisis makes ...
