Effects of water and nitrogen on yield and fruit quality of tomato under furrow irrigation and plastic film mulching cultivation
摘要
Abstract
An experiment was conducted in 2012 to acquire the optimal adjustment modes of water and nitrogen for tomato under furrow irrigation and plastic film mulching cultivation in arid regions of Northwest China .The results showed that the 85% of CK irrigation caused no significant effect on the yield of tomato ,but the 65% or 45% of CK irrigation decreased the yield significantly .The 3/4 of CK nitrogen application produced no significant impact on the total and mar-ket yield of tomato .The fruit color index ,firmness ,SSC and soluble sugar content increased ,but the organic acid con-tent decreased as the irrigation water decreased .The results also indicated that different nitrogen application rates pro-duced no effect on the SSC and organic acid content .However ,the soluble sugar content increased when the nitrogen ap-plication was decreased .With the irrigation and nitrogen decreasing ,the vitamin C content showed a rising trend firstly , and then decreased .Considering the yield ,fruit quality and water use efficiency (WUE) comprehensively ,the combina-tion of 416 .76 mm irrigation water (85% of CK) and 117 .6 kg・hm-2 pure nitrogen application (3/4 of CK) was an op-timal combination for high yield and high quality of tomato under furrow irrigation and plastic film mulching cultivation , which might be recommended in the arid regions of Northwest China .关键词
