Tomatoes need scaffolding or vines to fix the main vines. Why?

Except for a few erect varieties, vines must be knotted in order to facilitate ventilation, light and field management. According to the variety and climatic conditions, conical platforms are generally adopted, and flower racks, herringbone racks or fences can be selected for large shelf varieties. In the season or area with humid climate and less sunshine, it is best to use fence shelves, and in the season or area with dry climate or high temperature and strong light, it is best to use flower arrangement, cone frame and herringbone frame. After being put on the shelf, vines should be tied in time according to the growth of plants, so that the plants can be evenly fixed on the shelf.

Keep the trunk and remove all the side branches in time. Spring tomatoes should be cultivated early in the short growing season, with close planting, early fruiting, high early yield and early senescence. Improving the unit price of opening: on the basis of using up the unit price of opening, the texture of the reserved side branches is 1 ~ 2 ears, and 2 leaves are left, which is out of center. Double-stem straight branch method: keep the original paper and the side branches under the first inflorescence, and remove all the remaining side branches to form double stems. It is suitable for middle and late maturing varieties with vigorous growth period and late fruiting. Generally, varieties with limited growth types adopt double dry pruning method.

The length-limited type has its own sealing characteristics and does not need to pick the core. When the growing plants in Wuhan grow to a certain ear, they should take off their heads. For small trees planted in Wuhan, 3-4 layers of ears are reserved, and 4-5 layers of ears are picked for middle-frame planting. For large-belt planting, the heads are picked about 45 days before transplanting. If the plant grows vigorously or for a long time, leave several layers of ears. If the plants grow weakly or for a short time, leave fewer ears. When coring, the top 2 ~ 3 leaves should be kept to ensure the growth and nutritional needs of the flowers and fruits below. Matters needing attention in coring and pruning. Insert the bamboo pole obliquely inside or outside the plant rope. The distance between two bamboo poles is about 40 cm, and the bamboo poles are placed horizontally on it to form a net fence. The ears of plants and fruits are fixed on the fence. This kind of support is well ventilated, but windproof. If the wind blows, the whole plant will easily fall down.

Cross shelf. Length1.7 ~ 2.0m.. With a relatively strong fence, insert a bamboo every 1 m along the tomato planting line, then insert a horizontal bamboo every 30 ~ 40 cm, and insert 5 ~ 6 layers on the ground every 30 ~ 40 cm. This kind of desk lamp is airy, but not strong. Tie the intersection tightly with straw, three ropes or plastic ropes. Tying vines means tying tomato stems to a bracket. When the vine is tied, the ear of fruit is also hung on the bamboo pole. Phosphorus and spikes are too heavy to prevent the stems from breaking. Rattan should be carried out several times more, and the plant should be increased by 20 ~ 30 cm. It takes about 4 to 5 times for a vine. There are spikes on the stem, which should be tied under the spikes, tied with rattan and hung on the spikes.

Vine materials include straw, triple coke, cloth, plastic rope, bandage and so on. The method of tying vines is to tie an 8-shaped knot between the fixed point of tomato stem and the fixed point of bamboo pole. Canes should not be tied too tightly or too loosely. In order to prevent the fixed point from moving too far up and down, left and right, the material of the rattan can make another circle at the fixed point of the bamboo pole. When tying vines, you can't tie the flower rope between the stem and the shelf. So as not to affect the development of ear.
