| Abstract: | The study was conducted on effects of different film-covering periods and different planting patterns on dryland potato.The results showed that soil moisture,water use efficiency and yield in furrow side of the furrow cultivation were higher than the ridge side of the culture in the same period.Those covered by autumn Film were higher than those by soil thawed film and film before planting at the same location in early spring.Especially,in the furrow cultivation in autumn could increase yield,compared with ... |
