Abstract

The invention discloses a formula fertilization method for juvenile camellia oleifera forest, which belongs to the field of formula fertilization, and is a method of fertilizing formula camellia oleifera forest based on 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 and the corresponding growth of young camellia oleifera forests; use principal component analysis, Delphi method and Pearson correlation analysis to screen out the topographic indicators, climate indicators and / or soil indicators that are correlated with the growth of young camellia oleifera forests Minimum data set; according to the minimum data set, establish a nutrient benefit model and calculate different nutrient distribution ratios; analyze nutrient use efficiency through data envelopment; determine different terrains, climates and soils according to the different nutrient distribution ratios and nutrient use efficiency The amount of fertilizer applied to Camellia oleifera forest under the same conditions. The formula fertilization method for juvenile Camellia oleifera forest proposed by the invention is applicable to different terrains, climates and soil conditions, thereby rationalizing fertilizer input, improving fertilizer utilization rate and growth of juvenile Camellia oleifera forest.

Description

technical field

[0001] The invention relates to the field of formula fertilization, in particular to a formula fertilization method for young camellia oleifera forests. 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.

[0003] Camellia oleifera sapling stage refers to the stage from after planting to before entering the fruiting stage, generally 4-6 years. Camellia oleifera young forest stage has vigorous vegetative growth, promotes the growth of spring and summer shoots, rapidly expands the root system and crown, increases the leaf area, cultivates a good tree structure, promotes the accumulation of nutrients in the tree, and lays the foundation for flower...
