大棚番茄滴灌试验

Drip Irrigation Experiment of Tomato in Plastic Greenhouse

为了示范推广大棚番茄膜下微灌技术,对番茄膜下滴灌与沟灌两种方式下灌溉用水量、棚内温湿度、发病率以及番茄产量等情况进行了综合分析研究,结果显示,使用膜下滴灌比沟灌省水54.8%,棚内气温提高2.4℃,地温相对提高3.6℃,棚内湿度降低14%,增产15.7%,增加收入11.4%。

To demonstrate the promotion of micro-irrigation technology under film in tomato, through drip irrigation and furrow irrigation under two methods of irrigation water, such studies of the temperature and humidity, the incidence rate and tomato yield were analyzed. The results showed that： using drip irrigation water-saving 54.8% of furrow irrigation, temperature in the plastic tents increased by 2.4℃, earth temperature increased by 3.6℃, humidity decreased by 14%, yield of tomato increased by 15.7%, revenue increased by 11.4%.
