摘要
利用防雨棚和测坑进行小管出流条件下树莓的耗水特性及土壤水分变化情况的试验研究。结果表明:树莓在现蕾—花期阶段的耗水量明显高于其他生育阶段,该阶段的耗水强度为2.43～2.80mm/d;增加开花时期的灌水量有利于作物产量的提高。
An experimental research was conducted on the water consumption pattern and changes in soil moistures ol raspberry under tubelet irrigation using rain-proof shelf and measuring pit. The results show that raspberry water consumption at budding and flowering stages is obviously higher than at other stages which ranges from 2.43 to 2.80 mrrdd, indicating that increasing watering during flowering period is beneficial to the increase in yields.
