Fertilizer special for organic cultivation of Camellia oleifera and preparation method thereof

Abstract

The invention discloses a fertilizer special for organic cultivation of Camellia oleifera and a preparation method thereof. The fertilizer comprises the following raw materials: soybean meal, a calcium magnesium phosphate fertilizer, a potassium-magnesium sulphate fertilizer, tea bran of Camellia oleifera, zinc sulfate heptahydrate, borax, etc. The fertilizer is prepared by the following steps: crushing, sieving, fermentation, stirring, and uniform mixing. The fertilizer comprises the following raw materials in percentages by weight: 25-75% of the soybean meal, 5-52% of the tea bran of Camellia oleifera, 6-23% of the calcium magnesium phosphate fertilizer, 9-19% of the potassium-magnesium sulphate fertilizer, 0.1-2% of zinc sulfate heptahydrate, and 0.1-2% of borax. The fertilizer has a scientific and reasonable formula, weight percentages of the raw materials are adjusted according to growth conditions for preparing the special-purpose fertilizer, in order to equalize nutrition of Camellia oleifera, improve better growth of Camellia oleifera, and improve soil environment as well as quality and oil output of Camellia oleifera; the fertilizer is safe and does not have pollution.

Description

technical field [0001] The invention relates to the technical field of fertilizers in forestry production, in particular to a special fertilizer for organic cultivation of camellia oleifera and a preparation method thereof. Background technique [0002] Camellia oleifera (Camellia oleifera Abel.) belongs to the family Theaceae (Theaceae) Camellia (Camellia L.) plant, alias: tea seed tree (Hunan), tea oil tree (Guangxi), white flower tea (Guangdong), is an evergreen shrub or small tree, is my country's endemic subtropical woody oil tree species. Camellia oleifera, as an economic forest tree species with high economic value, wide application, strong adaptability and great potential for comprehensive development and utilization, is an important woody oil tree species in southern provinces of my country. At the same time, Camellia oleifera has strong adaptability, beautiful tree shape, long flowering period and long life span. It is an excellent tree species for landscaping and ...

AI Technical Summary

Problems solved by technology

[0004] Camellia oleifera is an important woody oil plant that integrates economic, social, and ecological benefits. Although it has a long history of cultivation in my country, the extensive management and predatory management of camellia oleifera forests in my country have remained in the process of planting camellia oleifera for a long time. There are unreasonable fertilization, the method of fertilization is in a state of blindness, and the proportion of fertilization is unbalanced. It is limited to simple chemical fertilizers or ordinary compound fertilizers, and the proportion of nutrients required by the growth law of Camellia oleifera cannot be applied. If the soil nutrients are insufficient, the camellia oleifera will grow slowly, the quality will be poor, the yield will decrease, and there will be obvious adverse phenomena of large and small years.

At the same time, due to the long-term use of chemical fertilizers, the soil fertility of the forest land is reduced, and the quality of camellia oil is reduced.

[0005] In recent years, special organic fertilizers have also been used in tea tree planting. However, in the process of production and use of traditional organic fertilizers, they are dirty, smelly, unhygienic, low in nutrient content, slow in fertilizer efficiency, large in size, complicated in production process, and unsuitable for use. Convenience and other disadvantages

Patent No.: 201410085190.1 "A special bio-organic fertilizer for camellia oleifera and its preparation method" discloses a bio-organic fertilizer, but the fertilizer is not made according to the growth of the camellia oleifera tree, and it is not specific to the required nutrition, and it is easy to Cause fertilizer waste, and there may be insufficient fertilizer efficiency

And the patent No.: 201210255083.X " special fertilizer for camellia oleifera " has announced a kind of special fertilizer for camellia oleifera according to the vegetative growth characteristic of camellia oleifera, through the rational proportioning of N, P, K, the special fertilizer for camellia oleifera of balanced application, but the composition raw material of fertilizer Many, complex production methods, high production costs, low promotion efforts
