不同灌水量和填充物对高温闷棚地温及茄子产量的影响

Effects of Different Irrigation Amounts and Fillers on Soil Temperature and Yield of Eggplant under High Temperature Tightly Greenhouse

高温闷棚技术可以提高塑料大棚内的土壤温度,有效杀灭土壤中的有害细菌、真菌、部分病毒及大部分害虫。研究了不同灌水量和填充物对高温闷棚地温及茄子产量的影响。结果表明:不填充有机质,50%灌水量处理的10 cm地温和茄子产量均高于其他处理。灌水量为田间持水量的100%,填充秸秆+有机肥+速腐剂可以有效提高10 cm和20 cm地温。

The high temperature tightly greenhouse technology could increase the soil temperature of greenhouse, and kill the harmful bacteria, fungi, some and most of pests. The effects of different irrigation amounts and fillers on soil temperature and yield of eggplant under high temperature tightly greenhouse were studied. The results showed that the 10 cm soil temperature and yield of eggplant with the irrigation amount of 50% without fillers were higher than other irrigation treatments. The 10 cm and 20 cm soil temperatures could be effectively increased by the fillers straw ＋ organic fertilizer ＋ straw-decomposing microorganisms under 100% of field capacity.
