Compound fertilizer special for camellia oleifera seedling raising stage and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizers, and discloses a compound fertilizer special for the camellia oleifera seedling raising stage. The compound fertilizer is prepared from, by weight, 15-25 parts of fermented mixed animal manure, 10-16 parts of plant ashes, 8-15 parts of urea, 10-20 parts of monopotassium phosphate, 5-10 parts of potassium chloride, 5-10 parts of ammonium phosphate, 1.0-2.2 parts of medium trace element additives, 10-20 parts of nutrition additives, 6-12 parts of plant pesticides and 5-20 parts of biogas water. The compound fertilizer is prepared special for seedling growth characteristics of camellia oleifera, nutrition is comprehensive, the survival rate of seedlings of the camellia oleifera can be effectively increased, growth of the camellia oleifera is promoted, and the root system is developed; the preparation method is simple and easy to implement, and the feasibility is high.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and relates to a compound fertilizer, in particular to a special compound fertilizer for camellia oleifera seedling raising stage and a preparation method thereof. Background technique [0002] Camellia oleifera, Theaceae, Camellia oleifera is an evergreen small tree. Its seeds can be squeezed for oil, hence the name. Camellia oil is a high-quality edible oil with clear taste and fragrance, rich nutrition and storage resistance; it can also be used in industry as lubricating oil and anti-rust oil. [0003] At present, the total area of ​​Camellia oleifera cultivation in the country is 3.67*10 6 hm 2 , mainly distributed in 14 provinces (autonomous regions, municipalities) in southern my country, among which Hunan, Jiangxi and Guangxi are the most. In the prior art, the traditional fertilization method is a single inorganic fertilizer or organic fertilizer, which has a very low utilization...

AI Technical Summary

Problems solved by technology

In the prior art, the traditional fertilization method is a single inorganic fertilizer or organic fertilizer, which has a very low utilization rate for Camellia oleifera seedlings, which is not conducive to the improvement and restoration of the soil of Camellia oleifera seedlings, but makes the soil more compact; and excessive use of urea, etc. Nitrogen fertilizers are also not conducive to the growth of branches and crowns of Camellia oleifera young forests, and reduce the ability of young forests to resist lodging, wind and snow, and pests and diseases

[0004] In the seedling stage of camellia oleifera, insufficient nutrient supply often leads to many problems: 1: There are many dormant buds, which cause the growth of camellia oleifera to be inconsistent, the shape of the tea tree is not good, and it is not suitable for large-scale cultivation; 2: The slow seedling period is long, and the seedling stage is prone to drought, causing The survival rate of seedlings is not high; the third is that Camellia oleifera has reached the fruiting stage, the fruit is shriveled, and the fruiting rate and oil production rate are reduced.
