Abstract

The invention discloses a controlled-release fertilizer for wax-apple trees and a method for preparing the controlled-release fertilizer. The controlled-release fertilizer is prepared by compounding reaction film-forming polymer coated urea with 4% coating quantity, reaction film-forming polymer coated urea with 5% coating quantity, coated magnesium-potassium sulfate, diammonium phosphate and potassium sulphate. The nutritional synchronous controlled-release fertilizer specially used for the wax-apple trees is prepared according to the nutrient requirement rule and the essential nutrients of the wax-apple trees, can supply the nutrients needed by the wax-apple trees continuously and synchronously to meet the needs of the wax-apple trees for three elements including nitrogen, phosphorus and potassium and nutritive elements including zinc and boron, can take effect for a long time, has the effects of improving the yield of wax apples, improving the taste of the wax apples and ensuring that the wax apples have good taste and the attractive appearance and solves the problem of high cost due to the single use of the controlled-release fertilizer.

Description

technical field [0001] The invention belongs to the technical field of slow / controlled release fertilizers, and relates to a lotus mist controlled release fertilizer and a preparation method thereof. Background technique [0002] Lotus mist, also known as Tiantao and Shuiyang apple, belongs to Myrtaceae (Myrtaceae), and is an important tropical and subtropical fruit. Lotus mist is originally produced in Southeast Asian countries, and now it is planted in Hainan, Guangxi, Guangdong, Yunnan, Fujian, Taiwan and other places. Taiwan is the place with the most advanced technology and the largest scale of planting lotus mist in the world. Hainan is the most ideal place for planting lotus mist in mainland China. The place. At present, lotus mist is one of the fruits with the best economic benefits among tropical fruits. It can be harvested after 3 years of planting, with an output value of 40,000 yuan per mu, which has very considerable economic benefits. Lotus mist has become one...
