Fertilization method for adult tea-oil tree forest formula

Abstract

The invention discloses a fertilization method for an adult tea-oil tree forest formula, and belongs to the field of formula fertilization. The soil measurement formula tea-oil tree forest fertilization method is based on terrain, climate and soil multi-factor influences. The fertilization method comprises the steps that different terrain indexes, climate indexes, soil indexes and corresponding tea-oil tree yields are measured; principal component analysis, the Delphi method and the Pearson related analysis method are adopted, terrain indexes, climate indexes and/or soil indexes with relevancewith the tea-oil tree yield are screened out to form a minimum data set; according to the minimum data set, a nutrient benefit model is built, and the distribution proportion of different nutrients is calculated; the nutrient utilization efficiency is analyzed through data envelopment; according to the different-nutrient distribution proportion and the nutrient utilization efficiency, the tea-oiltree forest fertilization amount under different terrain, climate and soil conditions can be determined. The adult tea-oil tree forest formula fertilization method is applicable to different terrain,climate and soil conditions, so that the fertilizer input is reasonable, the fertilizer utilization rate is increased, and the adult tea-oil tree forest yield is increased.

Description

technical field [0001] The invention relates to the field of formula fertilization, in particular to a formula fertilization method for adult Camellia oleifera forest. 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 China. It is a unique pure natural high-grade oil plant in China. Camellia oleifera, as a high economic value oil crop, has strong adaptability and does not compete with crops for arable land. The yield of camellia oleifera is not only affected by the quality of soil fertility, but also by topography, climate and soil. Therefore, it is expected to vigorously develop Camellia oleifera plantation by selecting suitable terrain and climate, and carrying out reasonable fertilization and tending, so as to increase the yield of low-yielding Camellia oleifera forest. [0003] Studies have shown that the yield of camellia oleifera is positiv...

Problems solved by technology

At present, the existing fertilization scheme is based on the sampling of a test site, which is only applicable to the area where the experiment is carried out, and improves the quality of soil fertility in a specific test site, while ignoring the influence of multiple factors such as terrain, climate and soil factors on the yield of camellia oleifera. Camellia oleifera forests suitable for different terrains and different climates

Existing fertilization technology cannot solve the current situation of low nutrient input efficiency in the process of tending Camellia oleifera under the diverse terrain conditions in Hunan
