不同地膜覆盖及小拱棚对草莓生长发育和产量的影响

用普通透明地膜，黑膜，银膜，３＃药膜，４＃药膜，８＃药膜覆盖地面，及用普通与带孔聚乙烯塑料薄膜作小拱棚栽培草莓。结果表明，小拱棚栽培草莓，果实成熟期比地膜与露地栽培早８－１７ｄ，且产量高。在小拱棚中，带孔棚对温温调节能力较强，可以节省劳力。种类地膜处理均能提高并保持地温，减少果实污染，除黑膜外产量均有提高。其中以８＃药膜和银膜效果最好，普通地膜在草莓生长期内膜下杂草较多。各类药膜对草莓叶片有不同程

Influence Of Arched Plastic House And Groud Covers On The Growth And Fruit Yield Of Strawberry

Arched polythylene plastic coverd house and arched polythelene plastic house with holes, transparent plastic ground cover, black ground cover, silver ground cover, and No. 3, No. 4 , No. 8 chemical ground cover were applied in strawberry cultivation. The results showed that the fruit mature period was 8- 17 days earlier, and the yields was higher in arched plastic house than those in ground covers and non -plastic cover cultivation. The temperature was controlled easily in arched polythylene plastic house with hole. The ground temperature increased and the fruit contamination caused by soil decreased in different round covers. Yields increased in round cover cultivation except for black plastic ground cover. Yields and growth increased more in No. 8 chemical plastic ground cover and silver ground cover than those in the other ground covers. More weed was the problem caused by transparent plastic house and leaves of strawbwrry were damaged by different chemical ground cover, espcially, in No. 4 chemical ground cover.
