| 摘 要： | 本试验通过大叶鸡冠和宝交早生两品种二层覆盖(大棚+地膜)和三层覆盖(大棚+小棚+地膜)的栽培试验,初步探明早熟丰产的保护地栽培形式。结果表明:(1)三层覆盖与二层覆盖成熟期基本相同,三层覆盖前期产量高于二层覆盖,但总产量是二层覆盖高于三层覆盖。二层覆盖具有省工省料,操作方便之优点。试验认为二层覆盖为草莓保护地生产的最佳覆盖形式。(2)宝交早生前期产量、总产量显著大于大叶鸡冠,是适宜于保护地栽培的比较好的品种。(3)宝交早生二层覆盖栽培是获得早熟高产的理想形式。

STUDIES ON THE RELATIONS BETWEEN MULTI-LAYER COVERING AND THE EARLY MATURITY AND YIELD OF STRAWBERRY |
| |
| Abstract: | We studied the early maturity and yields of two strawberry varieties; Bigleaved Cockscomb and Baojao Early strawberry cultivars. The experiment was conducted under different multchings, i. e. multched by big tent and ground plastic cover and 3-layer multching(big tent, small-arched tent and ground plastic cover) so as to achieve the protection cultivation pattern of early mature and rich harvest.The experimental results show: (1)The mature stage of 3-layer multching is basically the same as that of double-layer multching. The output of strawberry multched by 3-layer multching in the early stage is higher than that of strawberry by double-layer multching. But the total output and production value of strawberry covered by double-layer multching are higher than those of strawberry covered by 3-layer multching. Moreover, double-layer multching is good to save workdays and materials and easy to handle so that it is the best multching pattern for strawberry production in the tent. ( 2 )Among the two strawberry vareties, the earliness, total output and total production value of Baojao Early cultivar in the early stage are obviously greater than those of the Big-leaved Cockscomb cultivat. Thus, Baojao Early is a better strawberry variety adaptible to the big tent cultivation. (3)The double-layer muetching is the best treatment for Baojao Early cultivar for the early mature and high yield in strawberry production. |
