Problems solved by technology

At present, the main chemical fertilizers used by kidney beans are quick-acting fertilizers. This type of fertilizer has a fast and short fertilizer effect. To meet the needs of kidney beans for nutrients throughout their life, they must be fertilized multiple times, which not only increases the labor intensity of vegetable farmers, but also increases labor costs. , reducing the economic benefit

Abstract

The invention relates to a special controlled release fertilizer for resin coated bean and a preparation method thereof. The special controlled release fertilizer is synthesized by 4 percent of thermoplastic resin coated potassium nitrate, 4 percent of thermoplastic resin coated ammonium nitrate, 4 percent of epoxy resin coated compound fertilizer, potassium sulphate compound fertilizer, etc. The special controlled release fertilizer for the bean of the invention is served as a base fertilizer to be applied only one time before sowing without dressing, thus acquiring relatively good yield-increasing effect, improving the utilization ratio of the fertilizer and saving labor.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for resin-coated kidney beans and a preparation method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Beans are widely cultivated in the world. my country's kidney bean cultivation is relatively large in Northeast China, North China, and East China. [0003] Kidney beans have a long shelf life, are resistant to transportation, and are easy to store. They are the main vegetables supplied in the market every year, and they are also one of the important foreign exchange earning vegetables for export in my country. In recent years, with the rapid development of my country's opening to the outside world, the increasing export trade and the continuous improvement of people's living standards, the demand for kidney beans continues to increase. [0004] Kidney beans belong to leguminous crops, and there are rhizobia in their roots...
