Abstract

The invention provides a special fertilizer for promoting flower formation and fruit swelling of lemons in red soil and a preparation method thereof. The special fertilizer is composed of urea, potassium sulfate, monoammonium phosphate, magnesium oxide, calcium magnesia phosphate fertilizer, zinc vitriol, humic acid, borax and a filler. The preparation method comprises the following steps: respectively pulverizing urea, monoammonium phosphate, calcium magnesia phosphate fertilizer and potassium sulfate, carrying out aggregation granulation by humidification and heating, meanwhile, adding a mixture of the borax, zinc vitriol, magnesium oxide, humic acid and filler, drying the granulated material, screening and cooling to obtain the special fertilizer for promoting flower formation and fruit swelling of lemons in red soil. The method has the advantages of wide raw material sources and high universality, and is easy to implement and simple to operate. The special fertilizer provided by the invention greatly enhances the yield of the typical red soil lemon garden in Southern China and obviously improves the product quality.

Description

technical field [0001] The invention belongs to the technical field of fertilizer preparation and utilization, and in particular relates to a special fertilizer for promoting flowering and fruit expansion of lemons suitable for red soil and a preparation method thereof. Background technique [0002] lemon( Citrus limon (L.) Burm.f. ) is an important species of citrus in the Rutaceae citrus genus. In the world's citrus planting industry, lemons occupy the third place. The whole body is a treasure and has a wide range of uses. It is a high-grade fruit that can be eaten fresh and processed.
