| Abstract: |
| The effects of altemate furrow irigation on open field spring cabbage were studied on soil moisture, plant
growth, psychology and water use efficiency, with furrow irigation and full imigation control. The results showed: compar-ing to furrow irrigation , altemnate furrow irmigation after revival saved water by 17 % , while water use efficiency increased 3.5 kg/m3; altermate furrow imigation after lotus seat saved water by 8%，while water use efficiency increased 3.4 kg/m3; comparing to full irrigation, furrow imigation saved water by 17 %，while water use efficiency increased 5.0 kg/m3. Comparing to full irrigation, altermate furrow irrigation after lotus seat could increase photosynthetic rate, root length density and total root surface area , reduce transpiration rate , increase econonmic yield by 24 % , increase water use efficiency by 8.4 kg/m3, while save water by 23 %. What's more, combined with suitable irrigaiton pipe and fertigation equipement, alternate furrow imigation is a useful and economical way for water saving. |
