Abstract

Long-acting fertilizer special for eucalyptus mainly comprises, by mass percent, urea, ammonium chloride, ammonium bicarbonate, monoammonium phosphate, calcium superphosphate, potassium chloride, copper sulfate pentahydrate, zinc sulfate heptahydrate, borax and organic matters. Trace elements are added reasonably, so that the eucalyptus can absorb various nutrients according to needs. A certain amount of the organic matter is added, water and nutrient retention of soil is improved, soil is modified, disease and insect damage is effectively prevented by applying the fertilizer, and eucalyptus yield is increased.

Description

technical field [0001] The invention relates to the field of compound fertilizer produced in forestry, in particular to a long-acting special fertilizer for eucalyptus. Background technique [0002] Eucalyptus is the general name of species of Eucalyptus in the family Myrtaceae, and its Latin name is Eucalyptus, which is native to Australia, Indonesia and the Philippines. Eucalyptus has been introduced to my country for more than 110 years, and it has become a strategic tree species for fast-growing and high-yield forests in southern my country. In 2002, according to the statistics of relevant departments, the area of ​​eucalyptus plantations in the world was 18 million ha 2 , accounting for about 25% of the tropical plantation area, providing 180 million m3 of timber every year 2 , China's eucalyptus plantations account for 12% of the world's total, accounting for 1.5 million ha 2 , mainly distributed in Guangxi, Guangdong, Yunnan, Hainan, Fujian, Sichuan, Hunan, Jiangxi...
