Compound fertilizer for simultaneously increasing oil-tea camellia seed yield and carbon sequestration capacity of oil-tea camellia stand

Abstract

The invention discloses compound fertilizer for simultaneously increasing oil-tea camellia seed yield and carbon sequestration capacity of an oil-tea camellia stand. The compound fertilizer is prepared from organic fertilizer base material and inorganic chemical fertilizer, and is specifically prepared from the following components in parts by weight: 20 to 25 parts of the organic fertilizer base material, 35 to 45 parts of urea, 10 to 15 parts of ammonium phosphate, 15 to 20 parts of potassium chloride, 10 to 15 parts of calcium magnesium phosphate powder and 1 to 2 parts of trace elements. The compound fertilizer which is capable of not only increasing the oil-tea camellia seed yield of the oil-tea camellia stand, but also enhancing the carbon sequestration capacity of the oil-tea camellia stand according to the nutritional growth characteristic of oil-tea camellia trees and through reasonable matching of the content of organic fertilizer, inorganic fertilizer and mineral elements and balanced application is provided, so that coordinated development of economic benefit and ecological environment benefit is realized.

Description

technical field [0001] The invention belongs to the field of fertilizers for economic forests, and in particular relates to a compound fertilizer for simultaneously improving camellia oleifera seed yield and carbon sink capacity. Background technique [0002] Camellia oleifera is one of the four major woody oil plants in the world. It grows in the mountains and hills in the subtropical regions of southern my country, mainly in Zhejiang, Jiangxi, Hunan, Guangxi, Guangdong, Hubei and other provinces. The unsaturated fatty acid content of camellia oil is as high as 90%, which is much higher than that of rapeseed oil, peanut oil and soybean oil, and the content of vitamin E is twice as high as that of olive oil, and it contains specific physiologically active substances such as camellia saponin. , with extremely high nutritional value, is a unique pure natural high-grade oil in China. In recent years, as an important economic and energy resource, the state has vigorously promot...

AI Technical Summary

Problems solved by technology

[0003] At present, the planting of camellia oleifera basically adopts the traditional planting method. In the fertilization of camellia oleifera, there are phenomena such as unreasonable fertilization amount, unbalanced fertilization ratio, and insufficient supply of restrictive nutrient elements, resulting in soil compaction, low yield, and low yield of camellia oleifera. The oil production rate is low, and the specific fertilizers for camellia oleifera currently on the market are not highly targeted, and there is no scientific formula according to the characteristics of the fertilizer required by camellia oleifera, and the effect of increasing the yield of camellia oleifera after application is not good

In addition, in the process of afforestation, the artificial Camellia oleifera forest uses the method of destroying green and burning mountains to damage the original mountain and hill vegetation, which seriously damages the local ecological environment and greatly reduces the CO2 fixed by the original vegetation. 2 Ability

In the past fertilizer experiments on camellia oleifera forest, most of the attention was paid to the effect of fertilization on the yield of camellia oleifera seeds and the quality of camellia oil, and few studies on the impact of fertilization on the carbon sink capacity of camellia oleifera forest ecosystem
