Formulated fertilization method for young oil tea forest

Abstract

The invention discloses a formulated fertilization method for a young oil tea forest and belongs to the field of formulated fertilization. The formulated fertilization method for the young oil tea forest is used for soil measurement based on influences of multiple factors including terrains, climates and soil. The fertilization method is adopted for measuring different terrain indexes, climate indexes, soil indexes and the corresponding growth amount of the young oil tea forest; a main component analysis method, a Delphi method and a Pearson correlational analysis method are adopted for screening out the terrain index, climate index and / or soil index which are correlated with the growth amount of the young oil tea forest in order to create a minimum data set; according to the minimum dataset, a nutrient benefit model is created, and different nutrient distribution proportions are calculated; the nutrient utilization efficiency is analyzed by means of data envelopment analysis; according to the nutrient distribution proportions and the nutrient utilization efficiency, the fertilization amount of the oil tea forest under different terrain conditions, different climate conditions anddifferent soil conditions is determined. The disclosed formulated fertilization method for the young oil tea forest is applicable to the different terrain conditions, the different climate conditionsand the different soil conditions, correspondingly input of fertilizer is reasonable, and the fertilizer utilization rate and the growth amount of the young oil tea forest are increased.

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...

AI Technical Summary

Problems solved by technology

[0004] The existing fertilization schemes are all based on the sampling of a test site, and are only applicable to the area where the experiment is carried out to improve the quality of soil fertility in a specific test site, while ignoring the impact of multiple factors such as terrain, climate and soil factors on the yield of camellia oleifera, and Not suitable for Camellia oleifera forests with different terrains and different climates

Therefore, the existing fertilization technology cannot solve the current situation of low nutrient input efficiency in the process of raising young camellia oleifera in Hunan, for example, under the conditions of diverse terrain.
