Long-lasting special fertilizer for rubber tree and preparation method thereof

Abstract

The invention discloses a long-lasting special fertilizer for a rubber tree and a preparation method thereof. The special fertilizer comprises the following effective components in parts by mass: 15-22 parts of nitrogen, 5-10 parts of phosphorus pentoxide, 10-15 parts of potassium oxide, 0.1-0.3 part of zinc, 0.4-0.6 part of magnesium, 0.2-0.3 part of molybdenum, 1-2 parts of dicyandiamide and 5-10 parts of humic acid. The long-lasting special fertilizer for the rubber tree disclosed by the invention is reasonable in formula and high in service efficiency; overall nutrition required for growth of the rubber tree is met; the disease resistance of the rubber tree is improved; diseases are reduced; a long-lasting effect is achieved; the application number can be reduced; time and labor are saved; meanwhile, soil can be improved; nutrient balance of the soil is ensured; the growth speed of the rubber tree is quickened by the application of fertilizer of which the dosage is best for growth of the rubber tree; the yield of dry rubber is improved; and sustainable production of rubber is achieved.

Description

technical field [0001] The invention belongs to the field of forestry, and in particular relates to a long-acting special fertilizer for rubber trees and a preparation method thereof. Background technique [0002] Natural rubber tree is a perennial tall tree plant, as an important strategically binding resource, it has an important strategic position in modern economic development and national defense construction. However, the area suitable for planting rubber trees in my country is limited, and natural rubber resources are scarce. In recent years, the gap has become larger and the contradiction between supply and demand has become increasingly prominent. [0003] my country's rubber trees are mainly planted in five provinces (regions) of Hainan, Yunnan, Guangdong, Guangxi and Fujian, belonging to the northern margin of the tropics and the southern subtropical range. The soil where rubber trees are planted is mainly brick red soil and red soil, most of which are poor and h...
