Introduction

Technological innovation and industrial poverty alleviation mechanism

The technical parameter correlation formula of the straw carbonization device and the biomass pelletizing system is: η=(W0-W1)/W0×100%, where the device energy efficiency ratio can reach 1:8 when the material moisture content (W0) is ≤15%. The whole-county promotion model can form an annual production capacity of 100,000 tons of biochar-based fertilizers, corresponding to the consumption of 250,000 mu of straw resources.

Four-link poverty alleviation matrix model

Analysis of the division of responsibilities equation: F(x,y)=αG+βE²+γC, including government policy factor (α=0.4), enterprise capital factor (β=0.35), and cooperative organization factor (γ=0.25). Case analysis shows that when the administrative resource orientation coefficient reaches 0.6, the poverty alleviation fund performance multiplier is magnified by 1.8 times.

Long-term benefit adjustment model

New professional farmer training technology: adopt a modular training system (STD_01-07 protocol specification) and implement a skill assessment mechanism with σ_ER≥0.75. The economic benefit regression equation y=2.74x+50.6 (R²=0.87) confirms that the per-mu income increase is positively correlated with the soil carbon sink increment.

Horqin Project Implementation Model

Running simulation data verification: The ERODE algorithm simulation shows that there is a strong correlation of γ=0.92 between protein content and carbon fertilizer application cycle. The compound income formula of poor households is W=Σ(LA+BA+DA)_{i°, of which labor income accounts for 57%, asset income accounts for 23%, and increased production returns account for 20%. The actual income increase rate of a typical case is 325 yuan/mu·year.}
