摘要
[目的]探讨了不同的肥料配比方式对水肥一体化栽培草莓产量的影响.[方法]以红颜草莓为试材,设置4个不同肥料配方和2个施肥时间进行田间试验,研究各处理对草莓产量的影响.[结果]大棚草莓在施用有机肥和腐殖酸复合肥的前提下,水肥一体化施肥方式以处理T4(用量30 kg/hm2,开花期施用10-52-7配方肥料,开花后施用20-20-20配方肥料,果实膨大期施用13-6-40配方肥料,10d1次)施肥增产效果最好,产量较常规施肥有极显著增加,与其他几个处理相比,产量也有显著增加.从前后期产量的差异显著性分析来看,水肥一体化处理与常规施肥,以及水肥一体化的不同施肥模式处理之间,前期产量差异都不显著,而后期产量存在明显差异.后期产量增加表明开花期施用10-52-7配方肥料提高了花果数量、果实膨大期施用13-6-40配方肥料使果实重量增加都可以使产量有所提高,且这两个途径效果相当(T2、T3处理).[结论]T4处理通过最合理的前中后期施肥配方,使花果数量和后期果实重量同时增加,后期产量极显著增加,总产量达46 386.0 kg/hm2.
Abstract
[Objective] To discuss the effects of fertilization prescription on strawberry yield in water and fertilizer integration.[Method] With Benihoppe Strawberry as the test materials,field test was designed by four fertilizer formula and two fertilization times.[Result] Under the premise of application of organic fertilizer and humic acid combined fertilizer in strawberry in greenhouse,T4 formula of water and fertilizer integration was as follows:30 kg/hm2 dosage,application of 10-52-7 formula fertilizer in flowering period,application of 20-20-20 formula fertilizer after flowering period,application of 13-6-40 formula fertilizer in fruit swelling period.Fertilizer application every 10 d could obtain higher yields.And the yield showed extremely significant enhencement compared with that of conventional fertilization,and had significant enhancement compared with those of yield.Significant analysis of the differences between early and late yield showed that there were no significant differences in early yield between the water and fertilizer integration treatment and the conventional fertilization,as well as among the different fertilization modes of water and fertilizer integration;but the late yield showed significant differences.Increase of late yield showed that application of 10-52-7 formula fertilizer enhanced the floral and fruit quantity,application of 13-6-40 formula fertilizer in fruit swelling period increased the fruit weight,which both enhanced the yield.The effects of two treatments (T2,T3) were equivalent.[Conclusion] T4 treatment enhances the floral and fruit quantity and fruit weight,and extremely improves the yield in late stage.The total yield reaches 46 386.0 kg/hm2.
