温室大棚蔬菜生产中滴灌带灌溉应用效果分析

Effect of Drip Tape Irrigation on Vegetable Production in Greenhouse

在温室大棚蔬菜生产中应用膜下软管滴灌技术，能为作物生长发育创造良好的水、肥、气、热等生态环境，使温室大棚内５～１５ｃｍ土壤层平均温度提高１．５～２℃，气温平均提高０．５℃，空气相对湿度降低１０％～１５％，改善土壤理化性状，减轻病害，省水、省肥、省农药，促进蔬菜早熟。

The paper tested and examed the vegetable product with drip tape irrigation in greenhouse. The results show that the irrigation with drip tape under plastic mulching film can make a good ecological environment for vegetables growing, e.i., water, fertilizer, air, temperature condition, etc., and it can increase the average temperature 1.5～2℃ in 5～15 cm soil layer in greenhouse, increase the average air temperature 0.5℃, decrease air relative humidity 10%～15%, improve the soil performance to decrease diseases and harmness, save water, also fertilizer and chemical, advance ripe season of the vegetables. That technology is worthy to spread in greenhouse.
