摘要:

【目的】 研究适合双膜覆盖条件下棉花干播湿出的灌溉方案。【方法】 在新疆阿克苏市沙雅县设置大田试验,设计3个灌水定额处理(S1:675 m3/hm2,S2:900 m3/hm2,S3:1 125 m3/hm2)、2个滴水频次处理(S4:675 m3/hm2+450 m3/hm2,S5:675 m3/hm2+300 m3/hm2+150 m3/hm2)和1个冬灌对照处理(CK:2 700 m3/hm2),共6个处理。分析不同灌溉定额及滴水频次对土壤水盐运移、水热效应及出苗率的影响。【结果】 (1)在0~40 cm土层,滴水频次相同,随灌水定额增加土壤平均含水率逐渐增加,表现为S1<S2<S3;灌水定额相同,随滴水频次增加土壤平均含水率逐渐增加,表现为S5>S4>S3;CK处理土壤平均含水率显著小于各干播湿出处理。(2)0~40 cm土层,滴水频次相同,灌水定额越大灌后土壤脱盐率越高;灌水定额相同,滴水频次越少,土壤脱盐率越高;CK处理脱盐率显著大于各干播湿出处理。(3)0~40 cm土层,滴水频次相同,随灌水定额增加土壤日均温度逐渐减小,表现为S1>S2>S3;灌水定额相同,随滴水频次增加土壤日均温度逐渐降低,表现为S3>S4>S5;CK处理土壤日均温度与S1处理无明显差异,且显著大于其余各干播湿出处理。(4)出苗率随灌水定额的减少而升高,随滴水频次的减少而降低。各处理出苗率表现为CK≈S1>S2≈S5>S4>S3【结论】 综合各处理土壤水盐、地温及出苗情况,S1(675 m3/hm2)为最佳出苗水处理。

Abstract:

【Objective】 To determine the irrigation scheme that will be suitable for dry sowing and wet-out cotton under double-film mulching conditions.【Methods】 By carrying out field experiments in Shaya County, Aksu City, Xinjiang.A total of six treatments were set: three irrigation quota treatments (S1:675 m3/hm2,S2:900 m3/hm2,S3:1 125 m3/hm2), two drip frequency treatments (S4:675 m3/hm2+450 m3/hm2,S5:675 m3/hm2+300 m3/hm2+150 m3/hm2) and one spring irrigation control treatment (CK:180 mm). And then the effects of different irrigation quotas and drip frequencies on soil water and salt transport, hydrothermal effect and seedling emergence rate were analyzed.【Results】 (1) In 0-40 cm soil layer, the drip frequency was the same. With the increase of irrigation quota, the average soil moisture content gradually increased, which was S1 < S2 < S3; With the same irrigation quota, the average soil moisture content increased gradually with the increase of drip frequency, showing S5 > S4 > S3; The average soil moisture content of CK treatment was significantly lower than that of dry sowing and wet-out treatment. (2) In 0-40 cm soil layer, the drip frequency was the same, the larger the irrigation quota, the higher the soil desalination rate after irrigation; With the same irrigation quota, the less drip frequency, the higher soil desalination rate; The desalination rate of CK treatment was significantly higher than that of dry sowing and wet-out treatment. (3) In 0-40 cm soil layer, the drip frequency was the same. With the increase of irrigation quota, the daily average soil temperature gradually decreased, which was S1 > S2 > S3; With the same irrigation quota, the daily average soil temperature decreased gradually with the increase of drip frequency, showing S3 > S4 > S5; The daily average soil temperature of CK treatment was not significantly different from that of S1 treatment, and was significantly higher than that of other dry sowing and wet-out treatments. (4) The emergence rate increased with the decrease of irrigation quota and decreased with the decrease of drip frequency. The emergence rate of each treatment was as follows: CK ≈ S1 > S2 ≈ S5 > S4 > S3.【Conclusion】 According to the soil water and salt, ground temperature and seedling emergence of each treatment, S1(675 m3/hm2) is the best seedling emergence water treatment.
