Moso shoot productive forest formula fertilization method

Abstract

The invention discloses a Moso shoot productive forest formula fertilization method, and belongs to the field of formula fertilization. The Moso shoot productive forest formula fertilization method isa soil testing and Moso shoot productive forest formula fertilization method under the influence of multiple-factors such as topography, climate and soil. The fertilization method is to determine different topographic indexes, climate indexes and soil indexes and corresponding bamboo shoot yield. By using principal component analysis, Delphi method and Pearson correlation analysis, topographicalindexes, climate indexes and / or soil indexes that are related to the bamboo shoot yield are screened out to form a minimum data set; according to the minimum data set, a nutrient benefit model is established, and the allocation proportion of different nutrients is calculated; the nutrient utilization efficiency is analyzed through data envelopment; and according to the allocation proportion of different nutrients and the nutrient utilization efficiency, Moso shoot productive forest fertilization amount is determined under different topographic, climate and soil conditions. The Moso shoot productive forest formula fertilization method is applicable to different topographic, climate and soil conditions, thereby rationalizing fertilizer input, improving fertilizer utilization rate and increasing bamboo shoot yield.

Description

technical field [0001] The invention relates to the field of formula fertilization, in particular to a formula fertilization method for bamboo shoot forests. Background technique [0002] Phyllostachys pubescens, also known as Nanzhu, is mainly forests for bamboo shoots, forests for timber and dual-purpose forests for bamboo shoots and timber. As a vegetable, bamboo shoots have always been loved by people, and their taste is fragrant and delicious, and they are regarded as treasures in dishes. The yield of bamboo shoots is not only affected by the quality of soil fertility, but also by topography, climate and soil. Therefore, by selecting suitable terrain and climate, and carrying out reasonable fertilization and tending, it is expected to vigorously develop bamboo shoot plantations to increase the yield of low-yield bamboo shoots. Existing studies have shown that the yield of bamboo shoots is positively correlated with fertilization and soil fertility quality, and rationa...

AI Technical Summary

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 bamboo shoots. Bamboo forests suitable for different terrains and different climates

Therefore, the existing fertilization technology cannot solve the current situation of low nutrient input efficiency in the process of tending bamboo shoots under the diverse terrain conditions in Hunan.
