Generally, it can grow upright before flowering and fruit setting. In the future, with the increase and enlargement of leaves and the appearance of flowers and fruits, plants will crawl and grow, so vines need to be supported, pruned and bound in the cultivation process. Tomato stems are semi-lignified and have certain toughness, belonging to herbaceous plants. When tying vines, you can also hang the ear on the bamboo pole to prevent the ear from being too heavy and breaking the stem. Tendrils should be tied for many times. For every 20-30cm height of the plant, tendrils should be tied 1 time, and * * * needs 4-5 times. Where there is an ear on the stem, it should be tied at the lower part of the ear, and the vine should be tied and the ear hung.

Erection methods include herringbone frame, fence frame and cross. The word "person" box. Near the plant, insert a bamboo pole obliquely from the inside out, so that the top ends of the two opposite rows of bamboo poles cross into a herringbone shape, and then connect them with a horizontal bamboo pole at the upper intersection. The height of the support is 170~200 cm. In open field or arch shed cultivation, the traditional method of hanging seedlings and tying vines is to insert bamboo poles into herringbone frames and tie the stems and vines of tomatoes to the bamboo poles for fixation. When tying vines, you should not tie the vines too tightly, otherwise, as the stems become thicker, the tying rope will stick in the stems of tomatoes, which will have an adverse effect on the growth of tomatoes.

Untie the plant from the rope, knock off the old leaves, twist the plant to the position of the same plant nearby, and then hang the vine. The fallen vines should be wound on both sides of the cultivation ridge in an orderly way in the same direction. When winding vines, the vines should bend naturally with the vines. Pull a rope on the ground of the planting row and pull 1 galvanized steel wires above it respectively. A stake or bamboo pole should be driven under the steel wire every 6~8m to support the steel wire to prevent the steel wire. Then tie the steel wire with a small rope and tie it to the ground rope.

Tie the first vine immediately after erection, which should be tied to the lower internode of the next leaf of 1 ear, and then tie a vine to each ear. When tying vines, don't damage stems, leaves, flowers and fruits, and tie them in an "8" shape with moderate tightness. The third plant should be tied loosely at one end of the plant. Similarly, the third plant should be tied to the fifth and sixth plants. The same is true for the 4th, 5th and 6th strains from north to south. The vine is backward, and the plastic film under the stolon breaks, so that the stem is close to the ground and wet soil is pressed on it. After adventitious roots grow out, the growth and stress resistance of plants will be greatly enhanced.
