Introduction

This technology is a land productivity improvement technology for salt-sand compound barren land, whichintegrates the main measures such as rapid decomposition of biochar and straw to improve land productivity andsoil water holding capacity, application of attapulgite for slow release and loss control of fertilizer to reduce waterand fertilizer leaching, application of farmland waste and biological bacterial fertilizer to promote the formationof soil aggregates, application of bacillus to eliminate continuous cropping obstacles, and high temperaturepyrolysis wood vinegar to mitigate salinization hazards, lt can increase soil organic matter by 12-17%, reduce the salinization degree by 10-15%, and improve the land productivity by 1-2 grades.
