Key Technology Integration of No-tillage and Precision Sowing of Summer Maize(Zea mays L.)
摘要
Abstract
The effects of the key technology integration of no-tillage and precision sowing including seed quality,agronomic measures and seed manure on growth and yield of summer maize in Huanghuaihai area were explored to solve the problem of sowing key technologies with field testing in 2012 . There were sig-nificant differences among single technology processing( technology of precision seed,technology of com-paction,technology of returning straw,technology of seed manure),CK and integration technology pro-cessing( JC) of no-tilling precision sowing in summer maize. The treatment of JC combined technology of precision seed,technology of compaction,technology of returning straw,and technology of seed manure. And its soil moisture content was higher than technology of compaction, technology of returning straw, technology of seed manure 15. 70%,16. 73%,18. 64%,and was higher than CK and technology of preci-sion seed 23. 18%. The plant height of JC was higher than precision seed,technology of compaction,tech-nology of returning straw,technology of seed manure and CK 21. 54%,19. 96%,24. 54%,18. 94%, 33. 14%. The per plant leaf area was 20. 43%,17. 10%,34. 42%,13. 05%,44. 07% higher,and the per plant dry weight was 37. 44%,30. 83%,48. 81%,22. 09%,58. 59% higher. The SPAD,seedling quali-ty,leaf Pn of JC were highest among all these treatments. The yield of JC was 10 886. 71 kg/ha,and it was higher than technology of precision seed, technology of compaction, technology of returning straw, technology of seed manure and CK 18 . 61%,11 . 96%,13 . 49%,9 . 89% and 39 . 04%. The benefit effi-ciency of JC than other treatments above was 10. 66%,4. 64%,6. 89%,5. 05%,29. 77%,respectively.关键词
