Abstract

The invention relates to a special controlled-release fertilizer used for scallion or onion and a manufacturing method thereof. The fertilizer is made by compounding 5 per cent thermoplastic resin-coated potassium nitrate, 4 per cent thermoplastic resin-coated urea, sulfur-coated compound fertilizer, potassium sulfate compound fertilizer, diammonium phosphate, etc. The special controlled-release fertilizer used for scallion or onion of the invention is manured once as base fertilizer before the transplantation of scallion or onion and the dressing is avoided; the invention has a good effect on increasing yield and can raise the utilization ratio of the fertilizer and save labor.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for green onions and onions coated with sulfur and resin and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Scallions are the main condiment vegetables. They not only have a large consumer market in China, but are also exported to Japan, South Korea, Southeast Asia and other countries. Now the cultivation area of ​​scallions in my country is about 350,000 hectares. Onion is storage-resistant, has a long supply period and is an important raw material in the food industry. It is very popular in the international market. Although the history of onion planting in my country is not long, it is now cultivated in various places, and the planting area continues to expand. It has become one of the main vegetables in my country and an important commodity in my country's export trade. [0003] Scallions and shallo...
