| Abstract: |
| 【Objective】In order to improve the sticky board, shallow surface layer and low soil fertility and activity of the sandy ginger black soil in southern Henan Province, the lodging resistance ability of summer maize in this area was improved and the farmland productivity of the sandy ginger black soil was improved. 【Method】This study in Henan province, Zhumadian Xiping county sand ginger black soil farmland, on the basis of the winter wheat rotary tillage and deep set rotary tillage (RT), deep ploughing (DP), soil root promoter (RP), Soil remediation agent (RA) and soil improvement agent (SI) five processing of sand ginger black soil farmland soil physical and chemical properties, soil fertility and enzyme activity, and summer corn lodging resistance character and the influence of maize yield in this experimental study. 【Result】The experimental results showed that DP, RP, RA and SI treatments could increase soil moisture content and decrease soil bulk density, among which the maturity stage reached a significant level (P<0.05); The activities of urease, sucrase and neutral phosphatase were significantly increased by DP, RP, RA and SI. The activities of urease, sucrase and neutral phosphatase were significantly increased by 17.79%-33.27%, 16.05%-27.50% and 15.87-25.40%, respectively, by applying soil conditioner. DP, RP, RA and SI treatments could significantly increase the contents of available P, ammonium N and nitrate nitrogen, and the contents of available P, ammonium n and nitrate nitrogen increased by 32.85%-55.66%, 3.30%-5.75% and 9.41%-14.86%, respectively, by applying soil conditioner. DP, RP, RA and SI treatment can significantly increase the summer maize plant height and stem diameter, increase the summer corn stalks resistance to bending force and aboveground stem section 3 transverse rupture strength, make the lodging resistance index increased, but had no significant effect on ear position height and center of gravity high, DP, RP, RA and SI treatment no significant difference of coarse grain yield components, but the spike length, spike grain number is significantly higher than RT treatment, soil conditioner under processing production is significantly higher than comparison between 8.82% and 15.73%, respectively, digging well promote root agent processing production. 【Conclusion】In conclusion, soil conditioning can significantly improve the soil environment, increase soil moisture content and reduce soil bulk density, improve soil nutrients and soil enzyme activities, enhance the lodging resistance of summer maize and achieve an increase in yield. This study provides technical reference for the root-promoting cultivation of summer maize in sandy ginger black soil in southern Henan province. |
