| Abstract: |
| The developing course and current situation of research on protective tillage techniques in arid areas are expounded and some existing problems are pointed out,such as: low soil temperature may restrain crop emergence;weeds,pests and diseases are serious;the match of tillage techniques and farm machinery is not good enough;and the quality of sowing and fertilizing needs to be improved.However,it is considered that protective tillage play an important role in preventing wind,fixing soil,reducing soil moisture evaporation,reducing soil pH value and improving the quality of saline-alkali soil,which has a broad prospect of application through technical innovation and integrated demonstration based on further efforts in solving the existing problems. |
