Abstract

The invention relates to a special resin-coated controlled-release fertilizer used for a lawn and a manufacturing method thereof. The special fertilizer is made by compounding 6 per cent thermoplastic resin-coated potassium nitrate, 7 per cent thermoplastic resin-coated ammonium phosphate, 6 per cent thermoplastic resin-coated diammonium phosphate, 7 per cent thermoplastic resin-coated diammonium phosphate, 4 per cent thermoplastic resin-coated urea, 5 per cent thermoplastic resin-coated urea, 6 per cent thermoplastic resin-coated urea, 7 per cent thermoplastic resin-coated urea 8 per cent thermoplastic resin-coated urea, potassium chloride compound fertilizer, etc. The special controlled-release fertilizer used for a lawn of the invention is manured once in October every year and the dressing is avoided. The invention has a good effect on increasing yield and can improve the utilization ratio of the fertilizer and save labor.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for resin-coated lawns and a preparation method thereof, belonging to the technical field of slow / controlled-release fertilizers. Background technique [0002] The production and utilization of turf has a long history. Since the 20th century, the modern turf industry has flourished all over the world, and it has penetrated into human life widely today. China's modern lawn industry started late, but since the 1990s, my country's lawn industry has also been greatly developed. At present, lawn has been widely used in my country's environmental protection, urban construction, gardening, sports, tourism, leisure and other fields. With the gradual improvement of people's living standards in our country, the lawn industry will have greater development. [0003] Fertilization is an important part of lawn maintenance and management. Lawn needs fertilizer different from general crops. It is mainl...
