通过设置不同的覆膜垄面和垄沟宽度比例,研究不同覆膜集雨方式对马铃薯生长发育的影响,结果表明,不同覆膜集雨方式均对马铃薯株高、叶绿素值、干物质含量、块茎产量、商品薯率有显著影响,影响程度依次表现为M_(50)G_(20)处理>M_(60)G_(10)处理>M_(40)G_(30)处理>CK。其中M_(50)G_(20)处理集雨效果最好,不同生育期均显著提高了马铃薯的株高、叶片叶绿素含量、干物质积累量,马铃薯产量、商品薯率分别比CK提高48.1%、21.0%。
The effects of rainwater harvesting on the growth and development of potato were studied by setting different film ridge width and furrow width ratio. The results showed that the pattern of rainwater harvesting was affected on the plant height, chlorophyll value, dry matter content, The yield and the commodity potato yield had a significant effect, and the influence degree showed the order of M 50 G 20 treatment> M 60 G 10 treatment> M 40 G 30 treatment> CK. Among them, M_ (50) G_ (20) had the best rainfall-harvesting effect, and the plant height, leaf chlorophyll content, dry matter accumulation, potato yield and commercial potatoes were significantly increased by 48.1% 21.0%.
