Tomato early-maturing and fruit-retaining training method

The invention relates to a tomato early-maturing and fruit-retaining training method. The method comprises the following steps of before a tomato strain blossoms, training to completely remove lateral buds, keeping the independent trunk and keeping apical dominance; strengthening water and fertilizer management on the tomato strain to promote healthy of the strain; after the tomato strain blossoms, performing flower-dipping treatment on the fruit of each spike flower to enable the first to fourth spike flowers to bear fruits; timely removing the fifth spike flower and the spike flowers behind the fifth spike flower; after reserving 4 to 5 leaves, pinching to promote growth of the fruits. In different specific periods during growth of tomatoes, the potato strain is respectively subjected to trunk culturing, lateral bud removal, fruit retaining during the front stage, flower removal and leaf reservation in the late period, pinching to promote growth of the fruits and the like, so that the tomato strain is kept healthy in the early period, the fruit bearing period is advanced, and the fruit bearing is improved; after fruit bearing, enough leaves are left to be subjected to photosynthesis, pinching is performed to promote fruit to be quickly expanded and matured, the tomato fruit maturing stage is obviously advanced, and the commercial value of the tomatoes is improved.
