Abstract

The invention discloses a mango controlled release fertilizer and a preparation method thereof. The controlled release fertilizer is prepared from 3-8% of envelope amount of reaction film-forming polymer coated urea, urea, diammonium phosphate, potassium chloride, borax and the like in a compounding manner. The special nutritional synchronous controlled release fertilizer for mango disclosed by the invention is reasonably proportioned according to the physiological characteristics and nutrient requirement rule of the mango, so as to achieve the targets of reducing fertilizing amount, synchronously supplying nutrients, providing fertilizer efficiency for a long period of time, and increasing production and upgrading. Thus, the production cost is reduced; non-point source pollution is also avoided; the economic benefit is improved; and the controlled release fertilizer has a wide application prospect.

Description

Technical field [0001] The present invention is the field of slow / controlling fertilizer, which involves a mango -controlled release method and its preparation methods. Background technique [0002] Mangifra Indica L. is a world -renowned tropical fruit tree. It is known as the "tropical king" and is one of the five world -famous fruits.Origin India, Malaysia and other places.Mango is also one of the most important tropical fruits in China. It is mainly distributed in Hainan, Guangdong, Guangxi, Yunnan, Sichuan, Fujian and Taiwan.Especially since the 1980s, China's mango commercial cultivation has developed rapidly, and it has become one of China's important tropical and subtropical cultivation fruit trees. [0003] With the increase of mango planting area, problems such as improving fertilizer and improving fruit quality have also been produced.At the same time, people pay more attention to the quality of fruits. Therefore, improving the quality of fruit is the key to the market...
