The results show that the predicted irrigations are basically correct, so this model is significant to predict irrigations of fruit trees in the productive practice.

结果表明，灌溉的预报基本符合实际情况，所以该模型在生产上有实用价值。

The results indicated that the water management measure of frequent irrigations under moderate water deficit at tillering stage could increase the grain yield of rice.

表明在分蘖期适度水分亏缺和增加灌溉次数的水分管理措施具有增产效果。
