A kind of formula fertilization method for moso bamboo shoot forest

Abstract

The invention discloses a formula fertilization method for bamboo shoot forests, which belongs to the field of formula fertilization, and is a method of fertilizing formula bamboo shoot forests based on soil testing under the influence of multiple factors of terrain, climate and soil; the fertilization method is to measure different terrain indicators, climate Indicators and soil indicators and the corresponding bamboo shoot 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 bamboo shoot 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, determine the fertilization of bamboo shoot forest under different terrain, climate and soil conditions quantity. The formula fertilization method for bamboo shoot forest proposed by the invention is applicable to different topography, climate and soil conditions, thereby rationalizing fertilizer input and improving fertilizer utilization rate and bamboo shoot output.

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-yielding bamboo shoots. Existing studies have shown that the yield of bamboo shoots is positively correlated with fertilization and soil fertility quality, and rati...

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.
