Tomato pruning methods and matters needing attention
1. Single-cropping pruning method The single-cropping pruning method is a pruning method that is widely used in tomato production. For single pruning, only one backbone is left for each tomato plant, all side branches are removed one after another, and the backbone is also topped when there is a certain number of ears. Generally, one leaf should be left when breaking branches, and it should not be broken off from the base to prevent damage to the backbone. Keeping leaves and breaking branches can also increase the number of plant leaves to promote growth and development, especially for the growth and development of fruits close to the leaves. Generally, 2 to 3 leaves are left on the top of the upper ear when pinning. It is not suitable to close the ear. If there are no leaves on the upper part of the ear, the growth and development of this ear will be greatly affected, and even the flower and fruit will fall or the fruit will not develop well. , The quality has dropped significantly. The single-cropping pruning method has fewer branches and leaves, and is suitable for close planting and early maturity cultivation. Single-cropping pruning uses a large number of seedlings per acre, with more ears and fruits at the top of the list, high output value in the early stage, and relatively higher production costs. The single-cropping pruning method can be divided into medium dense planting according to the planting density and the number of remaining fruits per plant. There are 3500-5000 plants per mu, with 2 to 4 ears per plant. This is the most commonly used method for tomato production in open and protected fields. . Appropriate dense planting, 2500-3000 plants per acre, 5-10 ears per plant, the production is called elevated tomato cultivation, this is the method that can be used for open field over-summer cultivation, and it can also be used for autumn and winter crops and winter spring crops in solar greenhouses. Kind of way. Appropriate sparse planting, planting about 2,000 plants per acre, leaving 15-25 panicles, and cultivating through the winter in a solar greenhouse. The growth period is more than 9 months. 2. Double-stem pruning method Double-stem pruning is based on single-planting pruning. In addition to the backbone, one side branch is selected as the second backbone, so it is called double-stem, and all other side branches and regenerated branches on the double-stem are removed. The second backbone should generally be the first side branch under the first inflorescence, which grows robustly, grows fast, and can grow and develop parallel to the original backbone (main stem) in a short period of time. The second backbone of the double-stem pruning is the same as the single-cropping pruning method. Double-stem pruning is suitable for medium and late ripening tomato varieties with strong growth and high seed prices, as well as areas with lack of seedling conditions. Compared with single pruning, double-stem pruning can save seeds and seedling costs, and increase the number of fruits per plant and the output value. The early output value and total output value were slightly lower, and less practical use in production. 3. Improved single crop pruning method In the backbone of the single pruning, save the first side branch below the first inflorescence, wait for it to bear 1 to 2 ears and topple. The pruning method has the advantages of both single cropping and double-stem pruning, which can mature early and produce high yield. The growth and development of the first ear on the first side branch is earlier than the third ear fruit on the backbone. In terms of production, if the planting density is too scarce or the lack of seedlings is severely broken, this pruning method can be used to make up for it. Four, tomato pruning matters needing attention For diseased plants such as virus diseases, pruning should be carried out independently to avoid artificial transmission of diseases. The side branches and other side branches under the first inflorescence, even if they are not kept as fruiting branches, should not be destroyed too early. Generally, 1 to 2 leaves should be left to make nutrients and assist the growth of the backbone. If it will affect the ventilation and light transmission if not removed, it should be removed. The topping should be done on sunny days, not on rainy days or when the dewdrops are still wet, to facilitate wound healing and avoid cross-infection of pathogenic bacteria. In combination with pruning, vines and plant types should be adjusted. Disclaimer: Some articles on this website are transferred from the Internet.
