Abstract

The effects of ridge and furrow rainfall harvesting planting system(RFRHPS) in different stimulated rainfalls on summer corn(Zea mays L.) ontogenesis, cumulative biomass and yields were studied. Results showed that the growth period of RFRHPS corn was earlier than bare flat(control). The plant height and the leaf area of RFRHPS significantly increased(p<0.05). The total biomasses of RFRHPS corn were 44.71%, 28.51% and 7.58% higher than those of the control in different rainfalls(230 mm, 340 mm and 440 mm) respectively. In 230 mm and 340 mm rainfall, the grain yields per plant of RFRHPS corn were 75.40% and 36.70% higher than those of the control, respectively, the ear lengths increased by 25.30% and 16.00%, and the grain numbers per ear increased by 59.30% and 29.20%, respectively. In 230 mm rainfall, the ear width and 1000-grain weight increased by 11.4% and 10.30% than those of the control, separately; in 440 mm rainfall, there was no significant difference for the grain yield between RFRHPS and control.
