Description

technical field [0001] The invention relates to the field of special fertilizers in forestry production, in particular to a special fertilizer for camphor and its preparation method and application. Background technique [0002] Camphor [Cinnamomum cz mphora (Linn) Presl], also known as small leaf camphor, camphor tree, black camphor, is a plant of the genus Cinnamomum lauraceae, a subtropical evergreen broad-leaved tree species. It is mainly distributed in southeast and south-central China, south of the Yangtze River Basin, especially in Taiwan, Fujian, Jiangxi, Hunan, and Sichuan. Cinnamomum camphora likes light, is slightly shade-tolerant, likes warm and humid climates, and is not cold-tolerant. It is suitable for growing in areas with an annual average temperature above 16-17°C and an absolute low temperature above -7°C; the soil requirements are not strict, and it is suitable for deep and fertile clay loam, It grows well in sandy loam, acidic soil, and neutral soil, an...

Problems solved by technology

However, due to the new construction and renovation of roads and houses, the soil in the Shanghai area contains more construction waste such as cement, fly ash, household waste, broken bricks, glass, asphalt fragments, cinders, concrete blocks and other alkalis. Sexual mixture, resulting in increased soil pH, lack of soil nutrients, and makes the effective soil bulk density of camphor root activities smaller. Therefore, in the past ten years, the yellowing trend of street trees - camphor has become more and more common, and the damage has become more and more serious. getting worse

If the disease is mild, the growth of camphor will be hindered and the shape will be abnormal, and if it is serious, the plant will die, causing large economic losses. At the same time, it also seriously affects the landscape of urban greening and the display of ecological benefits.

[0004] Existing fertilizers are not effective in preventing yellowing of camphor, and a better fertilizer is needed to change the status quo

At present, the special fertilizer and its application of the street tree - camphor tree in our country are still blank. The research and development of its special fertilizer is of great significance to alleviate the yellowing trend of the street tree - camphor tree and promote the growth of camphor tree
