河套灌区覆膜沟灌对加工番茄生长效应与品质的影响

针对传统灌溉中存在不足，在内蒙古河套灌区研究了沟灌覆膜和无覆膜形式对加工番茄植株生育指标、品质、水分生产率、地上植株干物质积累量和番茄产量以及经济效益的影响。结果表明：覆膜处理对沟灌措施下的番茄植株的株高相比无覆膜处理增加达43％，茎粗增加达45％，番茄红素分别增加6．5％～25．4％；水分生产率及地上植株干物质的积累也分别提高了56％和22％，植株产量增长了1848．15～2768．89 kg·667m－2，农民也得到了692．75～1592．75元·667m－2的增产收入。因此在沟灌加工番茄生产中采取覆膜种植能有效促进生长并能取得良好的经济效益。

Effect of mulching and furrow irrigation on growth and processing quality of tomato in Hetao irrigation district

Effect of mulching and furrow irrigation on growth index, quality, water use efficiency, dry matter accumulation of shoot, yield and economic benefit of processing tomato were investigated to overcome the disadvantages of traditional irrigation methods in Hetao irrigation district. The results indicated that plant height was increased by 43%, stem diameter by 45%, lycopene content by 6.5% to 25.4%, water use efficiency and dry matter accumulation of shoot by 56% and 22%, yield by 1848.15 kg·667m^-2 to 2768.89 kg·667m^-2, and the income by 692.75 yuan·667m^-2 to 1592.75 yuan·667m^-2 under mulching-furrow irrigation. This result shows that mulching and furrow irrigation could effectively promote growth of processing tomato and offer considerable economic benefits.
