不同类型叶面肥在设施番茄上的应用效果

Application Effects of Different Types of Foliar Fertilizers on Protected Tomato

为了解不同类型叶面肥对设施番茄的效果,研究了8种叶面肥对番茄生长、产量及果实性状的影响。试验结果表明,喷施叶面肥均能增加株度、茎粗和单株叶面积,增强植株长势,还能改变果实大小和形状,增加产量,提高糖度,降低酸度,改善果实品质。与对照相比,处理2的番茄植株长势强,植株更高,粗度更大,结果多,果实大,增产19.57%,糖度高17.43%,酸度和对照相当。应用DTOPSIS法对番茄果实性状指标进行综合评价,结果表明处理2的Ci值最大,为0.8136,效果最优。因此,在番茄生产上推荐采用中微量元素肥喷乐红进行叶面喷施。

In order to understand the effects of different types of foliar fertilizers on protected tomato growth,the effects of eight kinds of foliar fertilizers on growth,yield and fruit characters of tomato were studied.The results showed that spaying foliar fertilizer could increase plant height,stem diameter,plant leaf-area,and enhance the growth of tomato plant.At the same time,it could change fruit size and shape,increase yield and sugar content,reduce acidity and improve fruit quality.Compared with the control treatment,the tomato plants sprayed with Penlehong in treatment 2 had strong growth vigor,higher plant height,thicker stem,more fruit,large-sized fruit,yield and sugar content increased by 19.57%and 17.43%,and the acidity was the same as the control treatment.DTOPSIS method was used to comprehensively evaluate fruit character indexes of tomato,the results showed that the Ci value of treatment 2 was the highest,which was 0.8136,and the effect was the best.Therefore,it was recommended to take Penlehong as foliar fertilizer in tomato production.
