滴灌加工番茄测土配方施肥效果分析

The Effect Analysis of Soil Tested Formula Fertilization on Drip Irrigation Processing Tomatoes

为进一步提升新疆加工番茄的施肥水平,验证和完善不同地力条件下测土配方施肥技术的科学合理性,为加工番茄的合理施肥提供参考依据。选择不同肥力土壤,设置测土配方施肥与常规施肥,对比研究两者对加工番茄养分吸收、产量、施肥效益的影响。相同栽培条件下,测土配方施肥对加工番茄的株高、单株果数、植株叶片的氮、磷、钾养分含量及产量均有一定的影响。测土配方施肥处理节肥增效明显,单果重、单株果数和产量持平或有所增加,最高增产10.19%,肥料用量明显减少,纯收益增加913-5323.5元/hm2。各施肥处理对番茄果实固形物、pH和总酸含量影响不大,测土配方施肥处理增加了番茄红素的含量。

In order to further enhance the fertilizer level of processing tomato, to validate and improve thescientific rationality of soil testing and formulated fertilization in different soil fertility conditions, to providereference basis for reasonable fertilization of the processing tomato in Xinjiang. To select different fertility soil,set the soil testing and fertilizer and conventional fertilization, comparing the effects of the processing tomatonutrient uptake, yield, fertilizer benefit. Under the same cultivation conditions, soil testing formula fertilizationof processed tomatoes, plant height, fruit number per plant, leaf N, P, K nutrient content and yield of all hadcertain influence. Soil testing fertilization fertilizer efficiency significantly, fruit weight, fruit number per plantand yield of flat or increase, the highest yield increased by 10.19%, but the amount of fertilizer significantlyreduced, net income increased 913-5323.5 yuan/hm2. The fertilization treatments on tomato fruit solids, pHand total acid content had no significant effect, soil testing formula fertilization treatment increased the contentof lycopene.
