摘要: 通过设置不同的灌水处理,研究了不同灌水时期组合对膜下滴灌马铃薯产量及水分利用效率的影响,以期为确定膜下滴灌马铃薯适宜的灌水方案提供理论依据。在总灌水量为1 725 m3/hm2、灌水次数均为7次的情况下,以不灌水处理为对照(CK),分别设置4个不同灌水时期组合,分别为B1(6月15日灌水300 m3/hm2、6月25日灌水225 m3/hm2、7月5日灌水300 m3/hm2、7月15日灌水300 m3/hm2、7月25日灌水225 m3/hm2、8月4日灌水225 m3/hm2、8月14日灌水150 m3/hm2)、B2(6月5日灌水150 m3/hm2、6月15日灌水300 m3/hm2、6月25日灌水225 m3/hm2,7月5日灌水300 m3/hm2、7月15日灌水300 m3/hm2、7月25日灌水225 m3/hm2、8月4日灌水225 m3/hm2)、B3(6月5日灌水150 m3/hm2、6月15日灌水300 m3/hm2、7月5日灌水300 m3/hm2,7月15日灌水300 m3/hm2、7月25日灌水225 m3/hm2、8月4日灌水225 m3/hm2、8月14日灌水225 m3/hm2)、B4(6月15日灌水300 m3/hm2、7月5日灌水300 m3/hm2、7月15日灌水300 m3/hm2、7月25日灌水225 m3/hm2、8月4日灌水225 m3/hm2、8月14日灌水225 m3/hm2、8月24日灌水150 m3/hm2)。结果表明:随着马铃薯生育时期的推进,叶面积指数、叶及叶柄和茎的干物质累积量以B1处理最高,均在出苗后65 d达到最大值;块茎干物质累积量在收获期达最大值,B1处理极显著高于其他处理。B1处理的块茎产量和商品薯率最高,分别达到53 246 kg/hm2,89.6%,与其他处理无显著差异,但水分利用效率显著高于其他处理。淀粉含量以CK最高,各灌水处理间无显著差异。Pro含量及MDA含量均以B1处理最低,显著低于CK。综上,B1灌水时期处理组合可作为膜下滴灌马铃薯生产中适宜的灌水时间组合。

Abstract: In this study, we set a series of different irrigation combinations. We systematically studied the effects of different irrigation time combinations on potato growth, yield formation and water use efficiency under drip irrigation. The total irrigation volume was 1 725 m3/ha, and the number of irrigation times was 7 times, the non-irrigation treatment was used as a control (CK), and four different irrigation periods are set respectively,B1 (irrigation 300 m3/ha on June 15th,irrigation 225 m3/ha on June 25th, irrigation 300 m3/ha on July 5th, irrigation 300 m3/ha on July 15th, irrigation 225 m3/ha on July 25th, irrigation 225 m3/ha on August 4th, irrigation 150 m3/ha on August 14th), B2 (irrigation 150 m3/ha on June 5th, irrigation 300 m3/ha on June 15th, irrigation 225 m3/ha on June 25th, irrigation 300 m3/ha on July 5th, irrigation 300 m3/ha on July 15th, irrigation 225m3/ha on July 25th, irrigation 225 m3/ha on August 4th), B3 (irrigation 150 m3/ha on June 5th,irrigation 300 m3/ha on June 15th, irrigation 300 m3/ha on July 5th, irrigation 300 m3/ha on July 15th, irrigation 225m3/ha on July 25th, irrigation 225 m3/ha on August 4th,irrigation 225 m3/ha on August 14th), B4 (irrigation 300 m3/ha on June 15th, irrigation 300 m3/ha on July 5th, irrigation 300 m3/ha on July 15th, irrigation 225 m3/ha on July 25th,irrigation 225 m3/ha on August 4th,irrigation 225 m3/ha on August 14th,irrigation 150 m3/ha on August 24th).The results showed that with the potato growth stage developed, the leaf area index, dry matter accumulation of leaves and petioles and stems were highest in B1 treatment, and all reached the maximum value at 65 days after emergence; the dry matter accumulation amount of tubers reached the maximum value during the harvest period, B1 treatment was extremely significantly higher than other treatments. The tuber yield and commercial potato rate of B1 treatment were the highest, reaching 53 246 kg/ha, 89.6%, which was not significantly different from other treatments, but the water use efficiency was significantly higher than other treatments.The starch content was highest in CK, and there was no significant difference between irrigation treatments. The Pro content and MDA content were the lowest in B1 treatment, significantly lower than CK. In summary, the B1 irrigation period treatment combination can be used as a suitable irrigation time combination for potato production under drip irrigation.
