pH响应材料及其在智能肥料中的应用
pH-responsive materials and their applications in intelligent fertilizer
摘要
Abstract
The development of the fertilizer industry is changing from traditional fertilizers to new-type fertilizers.The use of fertilizers has played a major role in ensuring food security,but the traditional fertilizers have low utilization rates,large nutrient losses and increased environmental risks.Most fertilizer products cannot achieve precise nutrient supply according to the nutrient requirements of crops.The research,development and innovation of intelligent fertilizers provide an effective way to solve this problem,matching the nutrient needs of crops more accurately in time and space.This paper systematically reviewed the types,sources and response mechanisms of pH-responsive materials,discussed the influence of the chemical structure of pH-responsive materials on pH-responsive behaviors,put forward the viewpoints that pH-responsive materials could promote the mutual feedback between root and fertilizer,analyzed the prospects of pH-responsive materials'application in intelligent fertilizers,and further clarified the application potential,the future research directions and the challenges of integrating pH-responsive materials into the field of green intelligence fertilizer creation.Based on the concept of mutual feedback between root and fertilizer,and comprehensively considering pH-responsive materials and the acidification of crop rhizosphere,the paper highlighted the designs of pH-responsive materials as a connection between root exudates and intelligent fertilizers,and put forward an innovative idea of developing pH-responsive intelligent fertilizers.The article also pointed out that the mutual feedback between root and fertilizer was the key to enhance the synergistic effects between the nutrient release of fertilizers and the nutrient uptake of crops.It was proposed that the green intelligent fertilizer based on the mutual root-fertilizer feedback,matching crop nutrient demand and having environmental friendliness would become the development trend of new-type fertilizers in the future.关键词
