[0070] like figure 2 As shown, the acquisition of the multidimensional influence coefficient of the Phyllostachys edulis bamboo shoot forest to be tested, the multidimensional influence coefficient includes: bamboo shoot type coefficient, precipitation evaluation coefficient, standing bamboo plant number coefficient and age structure coefficient, wherein, the acquisition of the described bamboo shoot type coefficient Methods as below:

[0071] S201, collecting respectively the second yield set and the third yield set corresponding to some historical covered bamboo shoot forests and natural bamboo shoot forests, calculating and analyzing the historical yield ratio of covered bamboo shoot forests and natural bamboo shoot forests;

[0072] S202. According to the historical yield ratio of covered bamboo shoots and natural bamboo shoots, determine the type coefficient of covered bamboo shoots and the type coefficient of natural bamboo shoots as follows:

[0073] A1=1

[0074] A2...

Embodiment 3

[0078] like image 3 As shown, the acquisition of the multidimensional influence coefficient of the Phyllostachys praecox bamboo shoot forest to be tested, the multidimensional influence coefficient includes: bamboo shoot type coefficient, precipitation evaluation coefficient, standing bamboo plant number coefficient and age structure coefficient, wherein, the acquisition of the precipitation evaluation coefficient Methods as below:

[0079] S301, collect several historical autumn precipitation and June precipitation respectively, obtain autumn average precipitation and June average precipitation;

[0080] S302. According to the average precipitation in autumn and the average precipitation in June, the precipitation evaluation coefficient of covered bamboo shoots and the evaluation coefficient of natural bamboo shoot precipitation are obtained:

[0081] B1=D1 / C1

[0082] B2=C2 / D2

[0083] Among them, D1 is the precipitation in autumn of the current year; D2 is the precipita...

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 ...
