摘要
为了筛选番茄最佳的锌肥施用方式,试验锌肥施用方式设底施和叶面喷施2种,每种施用方式的锌肥施用量均设2个水平(22.5、30.3 kg/hm2),以不施锌肥处理为空白对照(CK),研究了不同施肥处理对番茄生长、产量、果实品质和经济效益的影响.结果表明:施用锌肥具有显著的增产提质效果,其中叶面喷施30.0 kg/hm2锌肥的株高、茎粗和SPAD值显著高于其他处理,与CK相比,单果重增加15.06％,可溶性糖、Vc和全锌含量分别提高33.56％、27.07％和140.89％,硝酸盐含量降低40.89％,增产17.03％,增收19.27％.番茄施用锌肥时推荐叶面喷施30.0 kg/hm2,番茄产量、品质和经济效益均达到最高.
Abstract
In order to screen the best zinc fertilizer application method for tomato,two zinc fertilizer application methods were tested:bottom application and foliar spraying.The zinc fertilizer application amount for each ap-plication method was set at two levels(22.5 kghm2 and 30 kg/hm2).The effects of different fertilization treat-ments on the growth,yield,fruit quality,and economic benefits of tomato were studied with no zinc fertilizer treatment as the blank control(CK).The results showed that the application of zinc fertilizer had a significant effect on the yield and quality improvement of tomato.Among them,the plant height,stem diameter,and SPAD value of foliar spraying of 30.0 kg/hm2 zinc fertilizer were significantly higher than those of other treat-ments,Compared with CK,the single fruit weight of this treatment increased by 15.06％,soluble sugar,Vc content,and total zinc content increased by 33.56％,27.07％and 140.89％,receptively,the nitrate content de-creased by 40.89％,the yield increased by 17.03％,and the income increased by 19.27％.The highest yield,quality,and economic benefits of tomato could be achieved by foliar spraying of 30.0 kg/hm2 zinc fertilizer.
