摘要1998年和1999年进行了田间试验，研究了不同颜色地膜覆盖和行覆盖对3个马铃薯品种“库卡金”、“AF 1437 -1”和“深红诺兰”的总产量、商品产量和美国等级的影响。虽然观察到行覆盖的马铃薯植株的出苗率和生长率增加，但对任何品种的产量都没有显著影响。在这两年中，所有覆盖处理显着增加适销对路的产量相比，没有覆盖。1998年，“深红诺兰”的产量在不同颜色的覆盖物之间表现出统计学上的显著差异，金属化银和红色高于黑色。1999年，使用金属化银而不是黑色覆盖物的“深红诺兰”的总产量和可销售产量都显着更高。对于“AF 1437 -1”，施用金属化银的总产量显著高于红色覆盖，而商品产量仅金属化银显著高于黑色覆盖。金属化的银覆盖物导致所有品种的马铃薯的最高销售产量。
ABSTRACT Field studies were conducted during 1998 and 1999 to determine the effect of different color plastic mulches and row covers on total and marketable yield and US grades of three varieties of potatoes, ‘Kueka Gold’, ‘AF1437-1’ and ‘Dark Red Norland’. Although there was an observed increase in the rate of emergence and growth of the potato plants with row covers, there was no significant effect on yield of any of the varieties. In both years all mulch treatments significantly increased marketable yields compared to no mulch. In 1998, yields of ‘Dark Red Norland’ showed a statistically significant difference between mulch color, with metallized silver and red being higher than black. In 1999, both total and marketable yields of ‘Dark Red Norland’ were significantly higher with the use of metallized silver rather than black mulch. For ‘AF1437-1’ total yield, with the use of metallized silver, was significantly higher than that of red mulch, and for marketable yield only metallized silver was significantly higher than for black mulch. Metallized silver mulch resulted in the highest marketable yields for all varieties of potatoes.
