摘要
2013年对吐鲁番葡萄采用滴灌方式进行灌水实验,灌溉定额分别为720、850和960mm,滴灌带间距设置为40和60cm,监测并分析葡萄生长期生长指标、耗水和产量等数据。结果表明:滴灌带间距为60cm时的葡萄在各项生长指标和产量上优于滴灌带间距为40cm的处理;各灌溉定额处理的葡萄整个生长期耗水由低到高再降低,耗水量和耗水强度随灌水量增加而增大,其中葡萄的浆果膨大期耗水量最大,其他依次为浆果成熟期和枝蔓成熟期、新梢生长期、花期和萌芽期;灌溉定额850mm的W2处理产量和水分利用效率也最高,优于灌溉定额960mm的W3处理,增加灌水量在一定范围内可以增加葡萄产量。在综合考虑产量与水分利用效率的情况下,滴灌带铺设间距为60cm,灌溉定额为850mm为宜。
The experiments of drip irrigation for Turpan grapes, with the irrigation quota of 720, 850 and 960 mm and the drip tape interval of 40 and 60 cm, were conducted in 2013 to monitor and analyze the growth index, water consumption and yield data of the grapes. The results showed that the growth indexes and yield of the grapes under the condition of drip tape interval of 60cm were better than that under the 40em interval; the water consumption of grape in different irrigation quota treatments all changed from low to high then dropped, the water consumption and water consumption intensity increased with the increase of irrigation water quantity, in which the water consumption quantity at the grape berry enlargement stage was the largest, followed by other berries mature and mature vines, shoots growing, flowering and budding; the grape yield and water use efficiency of the W2 treatment with 850 mm irrigation quota were the largest, which is better than those of the W3 treatment with 960 mm irrigation quota irrigation, the increase of irrigation quantity within a certain range could increase the grape production; comprehensively considering the factors of yield and water use efficiency, the drip tape laying interval was decided as 60 cm and the irrigation quota was decided as 850 mm.
