可降解膜覆盖对小型西瓜产量和品质的影响

为了筛选适宜北京地区设施小型西瓜栽培使用的可降解覆盖材料,以黑色塑料地膜、黑色无纺布地膜(可降解)以及银色反光布地膜(可降解)为试验材料,研究了不同地膜覆盖对小型西瓜生育期、长势、根系活力、产量及品质的影响。结果表明:3种覆盖材料对西瓜产量的影响差异不显著,但黑色无纺布地膜覆盖处理下西瓜植株雌花开放较集中,根系活力、果实品质等指标优于其他处理,且可在6个月内降解。从效益、省工、环保等方面综合考虑,在北京地区早春大棚吊蔓栽培小型西瓜,建议选用黑色无纺布作为地膜覆盖材料。

Effect of Degradable Covering Film on Yield and Quality of Mini Watermelon

In order to select degradable covering film for mini watermelon under facility cultivation in Beijing area，this paper took the black plastic mulch，black non-woven film mulch（biodegradable） and silver reflective cloth（biodegradable） as experimental material，and studied the effect of different covering films on growth period，growth vigor，root activity，yield and quality of mini watermelon．The results showed that there were no significant diferences in the effect of these 3 films on watermelon yield．But the female flowers of the plant under black non-woven mulch blossomed concentrately，and its root activity and fruit quality were better than that by the other treatments．Moreover，it could be degraded within 6 months．Thus，we suggested to use black non-woven mulch as covering film in early spring under plastic shed for mini watermelon cultivation in Beijing area．
