Formula fertilization method for adult Camellia oleifera forest

Abstract

The invention discloses a formula fertilization method for an adult camellia oleifera forest, which belongs to the field of formula fertilization, and is a method for fertilizing formula camellia oleifera forest by soil testing under the influence of multi-factors of terrain, climate and soil; the fertilization method is to measure different topographic indexes and climate indexes and soil indicators as well as the corresponding Camellia oleifera yield; use principal component analysis, Delphi method and Pearson correlation analysis to screen out topographic indicators, climate indicators and / or soil indicators that are correlated with Camellia oleifera yield to form the minimum data set; according to the According to the above minimum data set, a nutrient benefit model is established to calculate different nutrient distribution ratios; nutrient use efficiency is analyzed by data envelopment; according to the different nutrient distribution ratios and nutrient use efficiency, the amount of fertilizer applied to Camellia oleifera forests under different terrain, climate and soil conditions is determined . The formula fertilization method for the adult camellia oleifera forest proposed by the invention is applicable to different terrains, climates and soil conditions, thereby rationalizing the input of fertilizers and improving the utilization rate of the fertilizer and the output of the adult camellia oleifera forest.

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
