技术简介

该技术首先采集检测热经作种植园土壤样品，构建热带经济作物种植园土壤资源数据库；根据GIS技术，绘制土壤酸度、肥力分布图；根据土壤酸、瘦现状，明确有机无机配施阻酸、土壤改良剂协同增效治酸和化肥平衡施用减肥增效控酸等关键技术在不同土壤酸度、肥力区域的应用；根据当地土壤管理投入状况，集成酸化土壤防治技术模式。

Introduction

This technology includes the following steps: Collect and detect soil samples from tropical cash cropplantations to build a database of soil resources; draw soil acidity and fertility distribution maps using Glstechnology; according to the current situation of soil acidity and fertility, clarify the application of keytechnologies such as organic-inorganic fertilization, synergistic acid treatment with soil conditioners andbalanced fertilizer application to increase efficiency and control acid in different soil acidity and fertility areas:according to the input of local soil management, integrate acidified soil prevention and control technologymode.
