1, one-handed pruning
Tomatoes can be pruned by single stem, which is suitable for close planting tomatoes. When pruning a single stem, each tomato plant only needs to keep one trunk, and other lateral branches on the tomato plant are removed, which can promote the emergence of more lateral branches. After that, in planting production, the trunk leaves about 5 ~ 10 ear. In the later stage of growth, it is necessary to remove some old leaves of pests and diseases to increase air circulation and light transmittance.
2, double stem pruning
Double stem pruning method is improved on the basis of single stem pruning. In addition to keeping the trunk of tomato, we should also pay attention to keeping a lateral branch and cultivate it into a second trunk, which can also become a fruiting branch in the later stage. In the later stage, the redundant lateral branches and regenerated branches on the double trunk should be cut off. The double stem pruning method is suitable for sparsely planted plots and is very simple to operate. About 5 ears can be left on each trunk for coring in production.
