Special fertilizer for tea-oil tree and preparation method thereof

Abstract

The invention discloses a special fertilizer for a tea-oil tree and a preparation method thereof. The special fertilizer comprises the following components in parts by weight: 48-54 parts of urea, 2-3 parts of diammonium hydrogen phosphate, 16-18 parts of soil nutrient, 6-10 parts of cottonseed hull, 4-6 parts of potato stem leaf powder, 10-12 parts of peanut shell, 10-15 parts of peasecod, 9-15 parts of dipotassium phosphate, 1-3 parts of potassium acetate, 2-3 parts of coal tar, 0.5-1.0 part of chromium oxide, 0.4-0.5 part of copper sulfate, 4-6 parts of lime powder, 5-10 parts of sodium borate, 0.7-0.9 part of sulfuric acid, 3-4 parts of urea resin and 18-20 parts of alternanthera philoxeroides. The urea is utilized as a raw material, a plurality of crop wastes and organic ingredients are added, a lot of macroelements, such as N, P, K and the like, and microelements are contained, and a certain ratio of soil nutrient is added, so that reasonable formulation is carried out, the special fertilizer can meet the requirements of the tea-oil tree on the nutrient, and can play the soil modification role. Nutritional ingredients of the soil are increased, and meanwhile, the market requirements of producing green high-grade edible oil can be met.

Description

technical field [0001] The invention relates to a special fertilizer for camellia oleifera and a preparation method thereof, belonging to the technical field of fertilizer manufacturing. Background technique [0002] Camellia oleifera is an important southern woody oil tree species in my country, and it is also one of the four major woody edible oil source tree species in the world. Camellia oil is clear in color, fragrant in taste, rich in nutrition, and durable in storage. It is a high-quality edible oil; it can also be used as lubricating oil and antirust oil It is used in industry; tea cake is both a pesticide and a fertilizer, which can improve the water storage capacity of the farmland and prevent pests in the rice field. Reasonable, the fertilization method is in a blind state, and the fertilization ratio is unbalanced. Generally, it is limited to a single fertilizer or a compound common fertilizer. It is not applied according to the proportion of nutrients required f...

[0002] Camellia oleifera is an important southern woody oil tree species in my country, and it is also one of the four major woody edible oil source tree species in the world. Camellia oil is clear in color, fragrant in taste, rich in nutrition, and durable in storage. It is a high-quality edible oil; it can also be used as lubricating oil and antirust oil It is used in industry; tea cake is both a pesticide and a fertilizer, which can improve the water storage capacity of the farmland and prevent pests in the rice field. Reasonable, the fertilization method is in a blind state, and the fertilization ratio is unbalanced. Generally, it is limited to a single fertilizer or a compound common fertilizer. It is not applied according to the proportion of nutrients required for the growth process of camellia oleifera. Not only can it not fully meet the growth needs of camellia oleifera, but also affect the growth and output of camellia oleifera , and may also lead to soil compaction, loss of fertilizer nutrients, damage to the ecological environment, etc.
