联合整地机械化作业技术联合整地机械化作业技术是用深松、旋耕、起垄机一次进地完成深松、旋耕、起垄作业项目，代替传统的翻、耙压、起垄３次进地作业。采用此项技术，可提高劳动生产率１．６６倍，并且提高了整地质量，深松深度平均达２５．６厘米，可打破犁底层；旋耕... Joint mechanized land preparation technology combined with mechanized land preparation technology is the use of deep pine, rotary tillage, furrow into a deep pine, rotary tillage, ridging operations, instead of the traditional flip, rake pressure, Ridge three times into the ground operation. Using this technology, can improve labor productivity 1.66 times, and improve the quality of soil preparation, deep pine average depth of 25.6 cm, can break plow bottom;
