玉米机械化生产条件下田间土壤持水与养分监测分析

Monitoring and Analysis of Soil Water Holding Capacity and Nutrients in Maize Nechanized Production

对玉米机械化生产条件下,生长期的田间持水量与土壤养分含量进行测定,观察玉米生长过程中的含水和含肥规律,针对其变化进行水肥的调整,改善玉米生长的长势,减少投入,增加粮食产量,指导农民科学种田。

This paper determined the field water holding capacity and soil nutrient content in growing period of Maize under mechanized production, to observe the law of water content and fertilizer in the process of corn growth, in view of its change, the adjustment of water and fertilizer has improved the growth of corn, reduced input, increased grain yield,and led farmers to farm scientifically.
