| 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 moistur... |
