摘要
以浙樱粉1号为材料,研究了不同叶面肥喷施时期(T1:定植前7 d喷施;T2:定植后7 d喷施;T3:定植后14 d喷施;T4:定植后21 d喷施)对樱桃番茄生长和产量的影响.试验结果表明,与不喷施叶面肥(CK)处理相比,喷施叶面肥处理可增加果实数量和单果质量,且随着喷施时间的后移,提高幅度逐渐增大.同时,喷施叶面肥处理提高了樱桃番茄的株高、茎粗、叶长和叶宽,有利于植株生长.此外,喷施叶面肥处理还提高了樱桃番茄叶片叶绿素含量(SPAD值),有利于增强叶片的光合能力.综上,喷施叶面肥通过促进樱桃番茄植株生长,提高植株光合能力,从而提高了樱桃番茄产量,且定植后21 d喷施效果最佳.
Taking cherry tomato cultivar Zheyingfen No.1 as material,the paper studied the effects of different foliar fertilizer spraying periods(T1:7 days before transplanting,T2:7 days after transplanting;T3:14 days after transplanting,T4:21 days after transplanting)on the growth and yield of tomato.The results showed that compared with the CK treatment(did not spraying foliar fertilizer),spraying foliar fertilizer increased the single fruit weight and fruit number,and the later the spraying period,the greater the incensement.Meanwhile,spraying foliar fertilizer increased the plant height,stem thickness,leaf length and leaf width,which was conducive to plant growth.In addition,spraying foliar fertilizer increased the chlorophyll content(SPAD value)of tomato leaves,which was conducive to enhancing the photosynthetic capacity of tomato leaves.In conclusion,spraying foliar fertilizer promoted the growth and improved the photosynthetic capacity of tomato plants,therefore made the increase of tomato yield,and spraying foliar fertilizer 21 days after transplanting had the best effect.
