Problems solved by technology

Frequent fertilization consumes a lot of manpower, but it cannot achieve the best effect of fertilizer
One is that quick-acting nitrogen fertilizers exist in the soil in an ionic state, and they are easily lost with irrigation water; the other is that for phosphorus fertilizers that have little mobility in the soil, the current fertilization methods are not conducive to better performance
So far, there is no public report on the controlled-release fertilizer dedicated to tulips that can solve the above problems well.

Abstract

The present invention relates to a tulip specialized controlled releasing fertilizer and the preparing method thereof. The fertilizer is obtained by recomponding the components of modified epoxy resin coated compound fertilizer, potassium muriate and the like with different coating quantities. The tulip specialized controlled releasing fertilizer of the invention is one-time applied when the tulip is replanted and the injury to the root system of the tulip is avoided in multi-time fertilizing, and the fertilizer has the advantages of saving labor and force, increasing the utilization efficiency of the fertilizer, satisfying the requirement of tulip for nitrogen, phosphorous and potassium in different growing periods, applying the fertilizer centralizedly to the root and facilitating the absorbing of the tulip to the nutrition.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for modified epoxy resin-coated tulips and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Tulip is a world-famous bulbous flower, with strong and straight flower stems, elegant and beautiful leaves, dignified and moving flowers, dazzling and lovable. In European and American countries, tulips are regarded as a symbol of victory and beauty, and many countries such as the Netherlands and Iran treasure them as national flowers. In recent years, my country's tulip cultivation area has been expanding, and the number has also increased sharply. At present, tulip has become one of the main flower varieties in the national flower market. [0003] At present, the fertilizers used by tulips are all kinds of quick-acting fertilizers. These fertilizers dissolve quickly after being applied to the soil, causing the ...
