| Abstract: |
| With Qianxi cherry tomato selected as indicating crop, plot experiment was carried out to study the effects of different irrigation methods on tomato root characters and yield during fruiting stage. The six irrigation methods adopted were: whole irrigation (Ⅰ), alternative irrigation (Ⅱ), growth row irrigation (Ⅲ), operated row irrigation (Ⅳ), early whole irrigation and late alternat
ive irrigation (Ⅴ), and early alternative irrigation and late whole irrigation (Ⅵ). The results indicated that root characters of tomato were significantly different at 0.01 level among different irrigation methods. Root volume under treatment Ⅵ was much higher than other treatments, and the bleeding sap of root and root activities reached 22.37 mg/min and 0.50 mg/(g·h). The single fruit mass and cumulated yield of tomato under treatment Ⅵ was higher than other treatments. In conclusion, early alternative irrigation and late whole irrigation (Ⅵ) could improve tomato root growth and increase tomato yield. |
