| 摘 要： | 通过膜下滴灌不同灌水量对番茄冠层生长和产量影响试验,结果表明:①随着灌水量的减少,相同生育期番茄冠层各生长指标生物量呈减小趋势;②不同生长指标相关性分析表明,番茄冠层生物量中叶干重对产量影响显著;③适度水分亏缺有利于番茄冠层生长和提高产量,4419 m3/hm2是膜下滴灌适宜灌溉量。

| Abstract: | canopy growth and yield of tomato under drip irrigation with plastic film mulch in experimental station of institute of agricultural engineering of Gansu Agricultural University were measured and analyzed.The results indicated that ① with the decrease of irrigation amounts,biomasses of all growth index of tomato canopy at the same growth stages.② Correlation analysis of the different growth index showed that leaf dry weight of canopy biomasses had a remarkable effect on yield.③ It was beneficial to canopy growth and increasing yield at temperate water deficit irrigation.Treatment W2 was the appropriate irrigation amount under drip irrigation with plastic film mulch. |
