摘要
[目的]在干旱半干旱的甘肃河西地区开展不同覆膜方式对设施茄子生长发育及产量的影响试验,探究不同覆膜方式在设施大棚茄子栽培中的实用性及应用效果。[方法]以品种“兰杂5号”为试材,研究3种覆膜方式(T_(1)起垄沟底覆单层膜、T_(2)起垄沟上覆单层膜、T_(3)覆双层膜)对茄子生长发育及产量的影响,以CK不覆膜为对照。[结果]与对照相比,茄子生长前期T_(1)处理叶绿素含量最低,而生长中、后期T_(2)处理叶绿素含量最低。整个生育期,T_(3)处理茄子株高、茎粗、光合速率及产量均为最高,T_(2)处理最低;T_(3)处理产量31383.30 kg/hm^(2),较T_(1)和T_(2)处理分别增产57.79%和10.90%。[结论]覆双层膜方式能够有效促进设施茄子的生长及提高产量,可作为甘肃河西地区设施茄子的一种栽培模式。
[Objective]To carry out the experiment on the effects of different film mulching methods on the growth,development and yield of facility eggplants in the arid and semi-arid Hexi region of Gansu,and study the practicability and application effect of facility eggplants in greenhouse cultivation.[Method]Taking“Lanza No.5”as test materials,the effects of three mulching irrigation methods(T_(1) on furrow bottom,T_(2) single-layer film above the furrow,T_(3) double-layer film)on the growth,development and yield of eggplant were studied,with CK(no film mulching)as control.[Result]In the early stage of eggplant,the chlorophyll content of T_(1) treatment was the lowest compared with the control,the chlorophyll content in T_(2) treatment was the lowest in the middle and late stages.During the whole growth period,the plant height,stem diameter,photosynthetic rate and yield of eggplant in T_(3) treatment were the highest,and those in T_(2) treatment were the lowest.The yield of T_(3) treatment was 31383.30 kg/hm^(2),which increased by 57.79%and 10.90%than that of T_(1) and T_(2),respectively.[Conclusion]The double-layer film irrigation method can effectively promote the growth and increase the yield of facility eggplant,and can be used as a cultivation model of facility eggplant in Hexi Region of Gansu Province.
