Abstract
The influence of sowing date on seedling growth of maize in wheat/maize/ soybean cropping system was studied.The results proved that early sowing could promote germinating rate and quicken the process of leaf emergence,increase plant height and plant diameter,leaf area and content of chlorophylls,thereby the photosynthetic capa-city of leaf was accelerated.It can accumulate more dry matter,guarantee better growth of seedlings,which might be a great potential for maize growth at the later stage.But much late sowing resulted in slim seedlings because of the disease and pests.We preliminarily concluded that the best sowing date of Lin'ao 4 was march 28 in Ya'an.
