英文摘要	A cultivation technique in combination of nutrient strategies has not been implemented on root growth, root-bleeding sap, lodging resistance and production of corn. Therefore, we conducted field trials implementing different cultivation techniques (ridge-furrow system with film covered (RF), ridge-furrow system with soil crust (SC), and flat soil planting system with no ridge and no cover (TF); with four nitrogen levels: 300 kg N ha(-1) ((3)); 200 kg N ha(-1) ((2)); 100 kg N ha(-1) ((1)) and 0 kg N ha(-1) ((0)), during 2015-2016. The aim of this work was to improve soil water storage, yield components, and production through regulating root growth and lodging resistance. The results showed that the RF system under different nutrient levels had significantly improved soil water storage, yield components which led to promote the development of roots in deep soil (0-50 cm) than that of SC and TF planting. The RF2 treatment significantly increased the root volume density (RVD), root weight density (RWD), and root diameter at various growth stages and attained the maximum value at 125 DAP (except root diameter) than that of TF2 treatment. The root surface area density (RSD) and root length density (RLD) were significantly increased in the upper 10-60 cm soil layer under the RF and SC cultivation patterns during silking and maturity stages than that of TF planting under different N levels. However, among the different treatments, there was non-significant variation in RSD and RLD at below 70 cm soil profile. The RF2 and SC2 considerably increased the root dry weight, and the root bleeding sap during entire growth stages of maize crop than that of TF2 planting. The RF system with different N levels delayed roots senescence in the later growth stage, and the production was significantly increased compared with SC and TF planting. Compared with SC2 and TF2 treatment, the RF2 treatment significantly increased the grain yield 5.7 t ha(-1) (104%) and reduces root (79%) and stem (95%) lodging rate; therefore, RF2 cultivation method might be an appropriate water saving approach in semi-arid regions.
