不同地膜覆盖对陇薯6号马铃薯产量的影响

Effect on Yield of Longshu 6 Potato Under Different Plastic Film Mulching

以陇薯6号为参试品种,采用全覆膜方式,探究黑白地膜覆盖对马铃薯产量的影响。结果表明,产量和土壤含水量各处理间差异显著(P≤0.05);大薯个数百分率、大薯质量百分率、小薯个数百分率、小薯质量百分率在黑地膜覆盖和白地膜覆盖处理间差异显著(P≤0.05);中薯个数百分率、中薯质量百分率、绿薯百分率、烂薯百分率、畸形薯率、干物质含量、休眠期在各处理间差异不显著(P>0.05)。产量由高到低为黑地膜覆盖(42 446.6 kg/hm^2)>白地膜覆盖(37 877.4 kg/hm^2)>露地不覆膜(30 763.6 kg/hm^2)。由此表明,黑地膜覆盖有利于薯块膨大,增加马铃薯产量;同时能提高土壤含水量,保墒效果好,抑制杂草生长,除草作用明显。

Taking Longshu 6 as testing variety,adopting the whole coated way,the influence of black and white plastic mulching on potato production was explored.The results showed that the difference on yield and the disposal of water content in soil between the treatment were significant （P 〈 0.05 ） ; The difference on percentage of the number of large potatoes and the yield of large potatoes, percentage of the number of small potatoes and the yield of small potatoes between black film mulching and white film mulching were significant （P~〈 0.05 ） ;The difference on number percentage of the medium potatoes, the yield percentage of the medium potatoes, the percentage of green potatoes, the percentage of the rotten potatoes, the percentage of malformed potatoes, dry matter the content of the dry substance, the dormancy stage between the treatment were indistinctive （/%0.05）. The yield from high to low is black plastic mulching （42 446.6 kg/hm2 ）〉white plastic mulching （37 877.4 kg/hm2 ）〉uncoated （30 763.6 kg/hm2） .There- fore, the black plastic mulching benefits the potato production, increases the soil moisture, inhibit weeds.
