Abstract

The invention relates to a controlled release fertilizer special for sulphur -plus-resin coated eggplant and the preparation method thereof, which is prepared with 3 percent of sulphur-plus-resin coated ammonium phosphate, 4 percent of sulphur-plus-resin coated potassium nitrate, 6 percent of sulphur-plus-resin coated potassium nitrate, sulphur-plus-resin coated urea of different coating thicknesses, potassium sulfate compound fertilizer, etc. , compound preparations. The controlled release fertilizer special for sulphur-plus-resin coated eggplant is adopted once applied fertilizer before the eggplant is transplanted, thereby being beneficial to the absorption, enhancing fertilization effect and saving manpower and efforts. The controlled release fertilizer special for sulphur-plus-resin coated eggplant can meet the requirement for nitrogen, phosphor and potassium by eggplant in the annual growth period. The nutrient is released slowly so as to reduce the fertilizer loss and be beneficial to a high yield and yield increase of eggplants.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for sulfur-added resin-coated eggplant and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Eggplant is native to tropical regions and has been cultivated in my country for more than 1,000 years. In the past, it was limited to cultivation in the south. In recent years, with the development of protected cultivation, the cultivation area has rapidly expanded to the north, which not only expands the cultivation area, but also increases the output and improves the efficiency. Eggplant has a long harvest period, high yield, transportation resistance, and good economic benefits. It has become one of the main vegetables for annual supply and off-season adjustments. [0003] The root system of eggplant is relatively developed, and the extension range can reach 120 cm, and it is mainly distributed in the cultivate...
