Fertilizer for eucalyptus planting

Abstract

The invention discloses a fertilizer for eucalyptus planting, which comprises the following raw materials in parts by weight: 95-105 parts of ammonium sulfate, 259-269 parts of urea, 36-46 parts of monoammonium phosphate, 145-155 parts of calcium superphosphate, 10-20 parts of calcium magnesium phosphate fertilizer, 170-180 parts of potassium chloride, 8-10 parts of molybdenum amino-acid chelate (complex), 8-10 parts of zinc amino-acid chelate (complex), 8-10 parts of manganese amino-acid chelate (complex), 8-10 parts of boron amino-acid chelate (complex), 8-10 parts of rare-earth amino-acid chelate (complex), 135-145 parts of nitro humic acid, 35-45 parts of amino acid, 20-30 parts of a biological agent, 8-18 parts of a synergist and 29-49 parts of a conditioner. The fertilizer contains nitrogen, phosphorus, potassium, boron, zinc, calcium and magnesium which are necessary for the growth of eucalyptus; fertilizer waste caused by volatilization, loss and soil adsorption is reduced; the utilization rate of the fertilizer is increased; the tree growth and tree physiological disease resistance are improved; the fast-growing superiority of eucalyptus is brought into full play; the cultivation of a short-cycle eucalyptus industrial raw material forest is realized; the nutrient balance of soil is ensured; and maximum economic benefits are obtained with minimum fertilizer input.

Description

technical field [0001] The invention relates to the preparation of fertilizer for planting eucalyptus, in particular to a fertilizer for planting eucalyptus. Background technique [0002] Eucalyptus belongs to the genus Eucalyptus of the family Myrtaceae, native to Oceania, and is mainly planted in Yunnan, Guangdong, Guangxi and other provinces, autonomous regions and western Sichuan in China. The planting varieties include blue eucalyptus, direct-dried blue eucalyptus, lemon eucalyptus, large-leaf eucalyptus and foliage-type copper money eucalyptus. With the development of the west and the implementation of the Yangtze River and Pearl River shelterbelt projects, the progress of returning farmland to forests has been accelerated, and the planting area of ​​eucalyptus has gradually expanded, and the prospect is promising. [0003] Eucalyptus likes warm climate, but it is not resistant to heat and humidity, and the climate is too hot to grow poorly. Yunnan is mainly distribu...

AI Technical Summary

Problems solved by technology

Nitrogen-deficient plants turn chlorotic or purplish-red, and growth is hindered; Potassium-deficient plants are weak, prone to lodging, and leaf color is dull; calcium and magnesium elements can increase the resistance of eucalyptus, making eucalyptus grow rapidly, and the tree shape is straight and well-proportioned. High rate; Zinc and boron elements promote the growth of eucalyptus tops. If these two elements are lacking, the top buds of eucalyptus will dry up or the buds will become swollen and brittle, easy to break in the wind, and form weak bushes, etc., which will seriously affect the growth of eucalyptus.
