Problems solved by technology

At present, the chemical fertilizers used for mulberry trees are mainly quick-acting fertilizers. These fertilizers dissolve quickly after being applied to the soil and are easy to lose with rainfall or irrigation water, especially nitrogen fertilizers.
In order to reduce nutrient loss, a small amount of multiple fertilization methods are often used in production. Mulberry trees need to be topdresse...

Abstract

The invention relates to a controlled release fertilizer special for sulphur-plus-resin coated mulberry and the preparation method thereof, which is prepared with sulphur-plus-resin coated urea of different coating thicknesses, potassium sulphate compound fertilizer, diammonium phosphate, etc., compound preparations. The controlled release fertilizer special for sulphur-plus-resin coated mulberry is adopted once applied fertilizer before the mulberry is germinated in spring, thereby reducing the harm done by multiple fertilizations to roots, meeting the requirement for nitrogen, phosphor and potassium by mulberry in the annual growth period and delivering good effect of yield increase.

Description

technical field [0001] The invention relates to a sulfur-added resin-coated mulberry special-purpose controlled-release fertilizer and a preparation method thereof, belonging to the technical field of slow / controlled-release fertilizers. Background technique [0002] China is the birthplace of sericulture and mulberry cultivation. In recent years, due to the promotion of advanced mulberry cultivation and management techniques, the cocoon production per unit of mulberry field has been continuously increased, and the economic benefits have also become better and better. In 2003, the area of ​​mulberry fields in my country was 760,000 hectares, and the export of silk products was 2.5 billion US dollars. Planting mulberry and sericulture is a labor-intensive industry, and it is shifting from a developed country to a developing country from a global perspective. my country has abundant labor resources, and planting mulberry and raising sericulture has relatively good economic be...
