Effect of straw mulching on root development and physiological characteristics of intercropped maize at seedling stage
秸秆覆盖对套作玉米苗期根系发育与生理特征的影响

Under the wheat/maize/sweet potato tri-crop intercropping system in the southwest China,we researched into the effects of different straw mulching treatments on root morphology,physiological characteristics of transplanted maize at seedling stage.Taking local traditional farming (T) as CK,the other two treatments were straw mulching (TS) and straw mulching plus decomposition catalysts (TSD).The entire experiment lasted for two years.Results show that straw mulching moderately increases root length and root ...
