摘要：

为探索地下滴灌条件下,毛管埋深对作物"地上部分-地下部分-产量和品质"相互作用的影响,合理配置滴灌措施,提高水分管理能力,该文研究了4种不同毛管埋深0、10、20和30 cm(CK、S10、S20和S30)对番茄植株生长、根系生长、光合产物分配、果实产量、品质和水分利用效率的影响,结果表明:与地面滴灌(CK)相比,毛管埋深为10 cm的番茄根系分叉数显著增加85.16%,但根长、根面积、番茄产量未显著提高,且番茄红素显著降低18.85%(P<0.05);毛管埋深为20 cm,盛果期I番茄叶面积指数显著增加23.37%,根长、根面积、根系分叉数分别显著提高43.22%、20.82%、176.61%,番茄产量提高22.35%,番茄果实品质显著改善,如可溶性固形物、可溶性蛋白、维生素C、番茄红素含量和糖酸比分别提高10.86%、32.34%、35.66%、33.97%和53.01%,水分利用效率显著提高35.91%(P<0.05);毛管埋深为30 cm,番茄根长、根系分叉数显著提高46.10%、122.37%,番茄产量显著提高19.53%,水分利用效率显著36.93%,但番茄红素显著降低34.02%。综合考虑番茄品质和产量,地下滴灌毛管埋深20 cm是较为适宜的布设方式。
