摘要: 为提高日光温室越冬栽培时土壤耕层温度,在温室南墙内侧分段填埋20cm (T1)、30cm(T2)、40cm(T3)3种不同高度泡沫板,以不填埋泡沫板为对照(CK)。连续30d观测并记录温室内离南墙30cm处不同深度土壤的温度值,从而对不同高度泡沫板的保温效果进行分析。结果表明,在温室南墙内侧填埋泡沫板有利于增加室内土壤耕层温度,且土壤耕层温度与填埋泡沫板高度呈正相关。在试验范围内以填埋40cm深度泡沫板效果最佳,与CK相比,南侧边际耕层温度可增加1~2℃。填埋泡沫板在晴天不影响土壤蓄热,而雪天、阴天土壤温度也可保持在8℃以上,避免了冻害的发生,在不影响作物(番茄)正常生长的条件下还可有效提高根系活力。研究结果可为减少气象灾害对温室生产的影响以及指导日光温室越冬茬作物生产提供依据,在越冬茬作物栽培中具有推广意义。

Abstract: In order to improve cultivated soil temperature of overwintering crops in solar greenhouse, 20cm (T1), 30cm (T2) and 40cm (T3) high foam board were buried inside south wall of solar greenhouse in different place,taking without foam board as CK. The temperature of different depth soil 30cm away from south wall was observed for 30 days, the heat preservation effect of different treatments was studied.The results showed that burying foam boards inside south wall was beneficial to increase the indoor soil temperature. There was close correlation between soil temperature and the height of foam boards among the three treatments, and T3 showed the best effect. The south margin soil temperature increased 1-2℃ compared to CK. Heat storage did not affected in sunny day, and the soil temperature could be kept above 8℃ in rainy days and snowy days, which could avoid freeze injury. The treatments increased the root activity significantly without affecting normal growth of the planting crops (tomato). The results could provide basis to reduce the damage of meteorological disasters to agricultural production in greenhouse, and to guidance overwintering crops production.
