在小拱棚内栽培草莓,分别覆盖麦草,地膜、砂子3种地面覆盖物,以不覆盖为对照(ck)。试验结果表明:1.物候期以地膜覆盖最早,早期产量占总产量的30％;麦草覆盖的最迟,早期产量占总产量的3％;二者始收期相差12天,其余居中。2.产量以麦草覆盖的最高,对照最低,其余二者居中。总产值以对照最低,砂子覆盖的其次,麦草覆盖的最高,地膜略低于麦草,二者无显著差异。且地膜覆盖亩投资少,管理方便,是较好的地面覆盖形式。
Strawberries were cultivated in small arch sheds and covered with straw, plastic film and sand, respectively, and covered with no cover (CK). The results showed as follows: 1. The earliest mulch cover was phenophase, the early yield accounted for 30% of the total output; the last straw mulching, the early yield accounted for 3% of the total output; 2. The highest yield of wheat straw coverage, the lowest control, the other two are centered. The total output value to the lowest control, followed by sand covered the second highest coverage of wheat straw, plastic film slightly lower than the straw, the two no significant difference. And mulching film mu less investment, easy management, is a better form of ground cover.
