番茄膜下滴灌栽培技术试验

Cultivation Technology of Drip Irrigation under Agricultural Film for Tomato

为了研究番茄抗旱节水栽培技术,采用番茄安装膜下滴灌和番茄覆膜不安装滴灌进行同田大区对比试验。研究结果表明,番茄覆膜不安装滴灌产量为3 988.6 kg/667 m2;安装膜下滴灌产量为5 614.3 kg/667 m2,比对照产量增加1 625.7 kg/667 m2,增产率为40.8%。表明番茄安装膜下滴灌,可以将少量的水直接输送到植株根部,满足番茄正常生长发育的需要,达到延长结果期和采收期,增加结果数量和单果质量,从而提高番茄产量和质量,增加种植效益。同时安装膜下滴灌使番茄在田间管理过程中根部灌肥、灌药方便,节省劳力,是一项高产高效栽培技术。

In order to study the drought-resistance and water-saving cultivation technology of tomato, the comparative trial was carried out in the same earth field, concerning the drip irrigation unused and used under agricuhura] film treatments. The results showed that the yields were 3 988.6 kg/667 m2 and 5 614.3 kg/667 m2 respectively when the drip irrigation was unused and used, and the yield of the latter was 1 625.7 kg/667 m2 higher than that of the former, with the increasing rate of 40.8%. Consequently, while the drip irrigation was used under agricultural film, small amount of water could he transported directly to the roots and met the needs of normal growth and development of tomato, with the fruiting period and harvesting time prolonged and the fruit number and single fruit weight increased, thereby improved the yield, quality and economic benefit of tomato cultivation. And it was convenient for irrigating the fertilizers and agrochemicals to the tomato roots and saving the labor, therefore it was a high yield and high efficiency cultivation technology.
