Abstract

The invention relates to a special slow release water soluble fertilizer for a rubber tree and a preparation method of the fertilizer. The fertilizer comprises the following raw materials in parts: 100-120 parts of urea, 40-60 parts of diammonium phosphate, 40-60 parts of calcium superphosphate, 60-80 parts of potassium nitrate, 60-90 parts of potassium chloride, 15-20 parts of chelated medium trace elements, 4-8 parts of sodium borate, 5-10 parts of soluble organic matters and 6-10 parts of small molecular hydrogel material. The invention further relates to the preparation method of the water soluble fertilizer. The special slow release water soluble fertilizer provided by the invention is complete in nutrition. Potassium nutrient has a slow release property. The fertilizer contains amino acid chelated medium trace elements and further contains 1.52-2.18% of organic matters, so that the fertilizer meets the nutrient cycling rule and the nutrient adsorption rule of the ecological system of a rubber forest, has promoting and adjusting effects on growth and latex production of rubber trees, can be used for effectively reducing the morbidity of dead skin of the rubber trees and improving the planting benefit of the rubber trees, and the utilization of the fertilizer efficiency of the water soluble fertilizer is improved.

Description

technical field [0001] The invention relates to a special slow-release water-soluble fertilizer for rubber trees and a preparation method thereof. More specifically, the invention relates to a slow-release special water-soluble fertilizer for rubber trees and a preparation method thereof, belonging to the field of special water-soluble fertilizers. Background technique [0002] The rubber forest ecosystem is a type of artificial ecosystem in the tropics and one of the most important pillar industries of tropical agriculture, making important contributions to ecological services and economic development in the tropics. Rubber is an indispensable and important strategic material for national economic construction, and the milky sap of rubber trees is the main source of natural rubber. The rapid development of industries such as automobiles and aviation has increased the global demand for natural rubber. As a big rubber consumer, my country needs to import 1.55 million tons o...
