摘要
为探求北疆地区微咸水滴灌条件下加工番茄高效生产的水肥耦合模式,以加工番茄‘金番3166’为研究对象,设置3个灌水量水平:5200(W1)、4500(W2)、3600 m^(3)·hm^(-2)(W3),3个施氮量水平:300(N1)、240(N2)、180 kg·hm^(-2)(N3),3个矿化度水平:1(S1)、3(S2)、5 g·L^(-1)(S3),采用L9(33)正交试验设计,研究灌水量、灌水矿化度、施氮量耦合对滴灌加工番茄的生长、产量及水肥利用效率的影响。结果表明:在微咸水灌溉时,W1N2S2处理地上部干物质积累量在果实膨大期达到最大(195.52 g·株^(-1))。与W1N1S1相比,W1N2S2、W1N3S3处理产量和灌溉水利用效率分别降低17.85%、27.19%和17.84%、27.16%,氮肥偏生产力分别增加6.11%和25.40%。综合考虑加工番茄生长、品质、产量及水肥利用效率,各因素影响大小表现为:灌水量>矿化度>施氮量。基于综合评分法对各指标进行评价,得出较优的水肥盐耦合模式为W1N3S3和W1N2S2。
To explore the water and fertilizer coupling model for efficient production of processing tomato under brackish water drip irrigation in northern Xinjiang,this experiment was conducted on processing tomato‘Jinfan 3166’with three water irrigation levels of 5200(W1),4500 m^(3)·hm^(-2)(W2)and 3600 m^(3)·hm^(-2)(W3),three N application levels of 300(N1),240 kg·hm^(-2)(N2)and 180 kg·hm^(-2)(N3),and three salinity levels of 1(S1),3 g·L^(-1)(S2)and 5 g·L^(-1)(S3).The effects of irrigation amount,salinity and nitrogen application on the growth,yield and water and fertilizer use efficiency of drip irrigation processing tomato were studied by L9(33)orthogonal test design.The results showed that aboveground dry matter accumulation in the W1N2S2 treatment reached a maximum(195.52 g·plant^(-1))at the fruit expansion stage under brackish water irrigation.Compared with W1N1S1,yield and irrigation water use efficiency decreased by 17.85%,27.19%and 17.84%,27.16%under W1N2S2 and W1N3S3 treatments,respectively,and nitrogen partial factor productivity increased by 6.11%and 25.40%,respectively.Considering the growth,quality,yield and water and fertilizer utilization efficiency of processing tomato,the influencing order of each factor was:irrigation amount>salinity>nitrogen application amount.Based on the comprehensive scoring method to evaluate each index,the optimal coupling mode of water,fertilizer and salt was W1N3S3 and W1N2S2.
