Description

Tea oil tree grows into forest special foliar fertilizer and preparation method thereof
Technical field
The present invention relates to fertilizer preparation field, grow into forest special foliar fertilizer and its preparation side more particularly to a kind of tea oil tree Method.
Background technique
Oil tea, also known as tea seed tree, tea oil tree refer to the oil species with higher cultivation economic value in Camellia Plants, It is the distinctive woody edible oil tannin plant of southern china.Tea oil tree is once planted, and is benefited, is hung for many years since planting third year Fruit, up to the best fruiting period after 6 years, the income phase is up to many decades.Oil tea is distributed mainly on 14 provinces and regions of south China, Hunan, Jiangxi, Guangxi are emphasis producing regions.Oil tea have the characteristics that Bioclimatic analysis it is wide, it is drought-resistant it is barren, resistance is strong, be contamination resistance Strong tree species；Autumn and winter bloom, and the florescence is long, are valuable nectariferous plants.Plantation oil tea can not only afforest territory, but also be able to maintain water Soil regulates the climate, beautifies the environment, with good economic efficiency, ecological benefits and social benefit.
Guangxi is one of China oil tea emphasis producing region, about 5,500,000 mu of the existing camellia oleifera lam area of the whole district, the total face of Zhan Quanguo oil tea The 10% of product fifty-five million mu, long-term about 3.5 ten thousand tons of tea-seed oil of annual output, the 16.9% of 200,000 tons of amount of Zhan Quanguo tea oil gross annual output, most High annual output is up to 4.3 ten thousand tons.The oil tea cultivated area and total output in Guangxi arrange national third position, the scientific and technological developmental achievement column whole nation the Two, first, the average per unit area yield column whole nation.61, the county (area) that the whole district has oil tea to be distributed, with Liuzhou, Guilin, Baise, rivers and ponds, he Based on five city Zhou Deng, wherein 100,000 mu of cultivated area or more of emphasis producing region county has: three rivers, Rong'an, Luzhai, Long Sheng, are put down at melt water Happy, respectful city bar horse, Fengshan, the Youjiang River, Tianlin County, Tianyang County, is reached the clouds, Long Lin, Napo County, eight steps, Zhaoping, rich river peace osmanthus directorial area etc. 19 counties (area).The county San Jiang camellia oleifera lam area reaches 740,000 mu, is the maximum county of whole district oil tea cultivated area, by the State Administration of Forestry It is named as " township of Chinese oil tea ".Meanwhile the county He Bama, the county San Jiang is named as " national economic forest (oil tea) production by the State Administration of Forestry Industry builds demonstration county ".
5,500,000 mu of camellia oleifera lam area, occupy national third position；Long-term 4.3 ten thousand tons of yield of tea oil occupies national third position, per mu yield 7.85 kilograms, be the first in the nation position.Guangxi camellia oleiferaindustry obtains certain development, but in existing camellia oleifera lam area, 80% the above are Low yield forest, since improper fertilization, fertilizer cannot be fully utilized, foliage top dressing (sprays foliar fertilizer), as root application fertilizer The features such as useful supplement has and is absorbed by blade, and for available nutrient not by soil fixing, absorption efficiency is high, quick, but at present There is not yet the relevant report for the special foliar fertilizer formula and application technique for being suitble to oil tea to grow into forest.
The disclosure of background above technology contents is only used for auxiliary and understands inventive concept and technical solution of the invention, not The prior art for necessarily belonging to present patent application shows above content in the applying date of present patent application in no tangible proof In the case where having disclosed, above-mentioned background technique should not be taken to the novelty and creativeness of evaluation the application.
