不同微灌方式对成龄库尔勒香梨生长及耗水规律的影响
Effects of Micro-irrigation Modes on the Growth and Water Consumption of Mature Korla Fragrant Pear Trees
摘要
Abstract
The irrigation methods included three kinds of micro-irrigation methods, surface drip irrigation, subsurface drip irrigation, and micro-sprinkler irrigation, and the traditional flood irrigation was used as control. Soil water potential in the root zone was monitored by a tensionmeter and gypsum blocks. The growth indices of fruit tree were recorded at different growth stages. The daily water use, crop coefficients and pan coefficients under different micro-irrigation treatments were estimated by water balance method. The results indicated that the tree water uses under micro-irrigation methods, surface drip irrigation, subsurface drip irrigation, and micro-sprinkler irrigation, decreased by 63. 91%, 68. 4%, and 57. 59% respectively as compared with that under flood irrigation, while the shoot growths, reduced slightly, by 5. 0%, 6.4% and 3.1%. Compared with the flood irrigation, the fruit volumes under the micro-irrigation treatments of different wetted percentage were all bigger, with the largest under surface drip irrigation treatment. Moreover, the fruit quality under micro-irrigation treatments was improved to some extent.关键词
