Embodiment 1

[0047] In this example, the precision fertilization method of 1.5-year-old fast-growing eucalyptus is used as a test:

[0048] In October 2014, a 1.5-year-old fast-growing eucalyptus was selected for sampling survey in a certain eucalyptus forest in Guangxi. Three repeated experiments were set up in each group, and each survey quadrat (20m×20m) was measured with a girth ruler and an altimeter. For breast diameter and tree height, select a standard tree, then fell it, and then cut it according to the Monsic layering method, each 2m is a section, apply the forest tree whole tree nutrition method, and weigh the whole plant according to the root, trunk, branches and leaves respectively According to the fresh weight of each organ of the tree, take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in the oven to a constant weight, weigh the dry weight, calculate the moisture content of each organ, and then calc...

Embodiment 2

[0080] In this example, the precision fertilization method of 2.5-year-old fast-growing eucalyptus is used as a test:

[0081] In October 2015, a 2.5-year-old fast-growing eucalyptus was selected for sampling survey in a eucalyptus forest in Guangxi. Three repeated experiments were set up for each group. Each survey quadrat (20m×20m) was measured with a girth ruler and an altimeter. For breast diameter and tree height, select a standard tree, then fell it, and then cut it according to the Monsic layering method, each 2m is a section, apply the forest tree whole tree nutrition method, and weigh the whole plant according to the root, trunk, branches and leaves respectively According to the fresh weight of each organ of the tree, take a small amount of representative samples according to each organ, weigh the fresh weight, bring it back to the room, dry it in the oven to a constant weight, weigh the dry weight, calculate the moisture content of each organ, and then calculate the w...

Abstract

The invention discloses a topdressing-type eucalyptus special fertilizer and a preparation method thereof. The special fertilizer contains the following effective components, and the a mass ratio of Nto P2O5 to K2O to Cao to MgO to Cu to Zn to Fe to Mn to B to humic acid to chitosan oligosaccharide to 5-aminolevulinic acid to beauveria bassiana to bacillus thuringiensis to a binder is (8-20):(5-10):(7-12):(0-25):(0-3):(0-0.2):(0-0.2):(0-0.1):(0-1):(0-0.3):(1-8):(0-0.5):(0-1):(0-2):(0-2):(2-10). According to the special fertilizer for the eucalyptus, the ratio of nutrients of nitrogen, phosphorus, potassium and the like required by growth of the eucalyptus is scientifically calculated according to the nutrient absorption distribution characteristic of the eucalyptus, and then scientific proportioning of the nutrients of nitrogen, phosphorus, potassium and the like is carried out by taking fertilizer supply rates of various soil and utilizing rates of various fertilizer nutrients as important factors, so that the provided eucalyptus special fertilizer can comprehensively meet accurate requirements of a large amount of nutrients in growth and develop of the eucalyptus in all stages,cost of the fertilizer is reduced, the utilization rate is improved, and then the yield and quality of the eucalyptus are improved.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a topdressing type eucalyptus special fertilizer and a preparation method thereof. Background technique [0002] Eucalyptus, also known as eucalyptus, is a general term for Myrtaceae and Eucalyptus plants, native to Australia and South America. Eucalyptus planting in my country has a history of more than 100 years, and the planting of eucalyptus has developed rapidly in the south of my country in the past ten years. Eucalyptus is listed as the first choice tree species for national industrial raw material forest afforestation because of its strong adaptability, rapid growth, short growth cycle, large biomass, straight trunk, wide range of uses, and high economic benefits. When the soil and climate conditions are suitable, the key to planting Sufeng Eucalyptus is seedlings and fertilizers. In terms of seedlings, since the tissue culture and cutting techniques are quite matur...
