Multi-dimensional phyllostachys praecox bamboo shoot forest yield estimation method and device

Abstract

The invention relates to a multi-dimensional phyllostachys praecox bamboo shoot forest yield estimation method, which comprises the following steps: respectively collecting first yield sets corresponding to a plurality of bamboo shoot forests covered by forest cultivation in 0-6 years in the history, and establishing a basic yield model of the bamboo shoot forests covered by forest cultivation in 0-6 years according to a regression algorithm; obtaining a multi-dimensional influence coefficient of the to-be-measured phyllostachys praecox bamboo shoot forest, obtaining a to-be-measured basic yield of the to-be-measured phyllostachys praecox bamboo shoot forest according to the basic yield model, calculating and analyzing the to-be-measured basic yield and the multi-dimensional influence coefficient to obtain an estimated yield of the to-be-measured phyllostachys praecox bamboo shoot forest, and through using a mathematical statistics method as a theoretical basis, establishing a basic yield model on the basis of the forest growing year, the influence of the bamboo shoot type, rainfall, the number of standing bamboos and the age structure of the bamboo shoot forest on the yield is considered and converted into the product of the coefficient and the basic yield, the bamboo shoot yield is estimated, the method can estimate the bamboo shoot yield, meanwhile, the bamboo forest cannot be damaged, a reliable calculation model is provided for industrial planning of farmers, and the method is used for deciding subsequent production and development.

Description

technical field [0001] The application relates to the technical field of agricultural products, and specifically relates to a method and device for estimating the yield of bamboo shoot forests of multidimensional lei bamboo. Background technique [0002] Phyllostachys praecox belongs to the grass family, and Bamboo is a cultivated species of Bambusa genus. Thunder bamboo originates in China's Zhejiang, Jiangxi, Shanghai, Jiangsu, Anhui, Fujian, Hubei, Hunan and Guangdong. It likes to be fertile, afraid of stagnant water, and has few fine roots. In areas with an average annual temperature of 15.30°C and an annual precipitation of 1400 mm, sunny, close to water sources, loose upper quality, slightly acidic or neutral sandy loam with good drainage and air permeability. It can be planted on dry land, on all sides, and on river beaches, and ordinary red soil and yellow soil are also suitable for cultivation. Thunder bamboo is an excellent bamboo species for bamboo shoots. Its ...

Problems solved by technology

Due to the use of random sampling for estimation, this work needs to be carried out during the harvest period of bamboo shoots, and the output of the next year cannot be well estimated

[0007] Therefore, the existing method for estimating the yield of bamboo shoots takes into account few influencing factors, which will cause a certain degree of damage to the bamboo forest, and the result is inaccurate and cannot realize the estimation of the next year's output.
