Early pruning and pruning techniques in the early evening preserves all lateral branches in the early stages of tomato growth, allowing the tomato to enter the ridge as soon as possible, and weaken and remove these side branches at the two critical moments when the ridge is closed and at the beginning of the fruit expansion. The method of weakening is to pick up or cut or twist branches or partial removal of lateral branches. The principle is that the branches cannot be too dense; the timing of removing all lateral branches is the initial stage of fruit enlargement. Remove these lateral branches at this critical period. Conducive to the transfer of nutrients to flowers and fruits. The implementation of the technology has three main points: First, before the ridging of tomato plants, allowing the growth of lateral branches. It is best combined with loose soil to promote root development very effectively. Second, after the tomato plant is ridged, the side branches may be picked up or cut or twisted or removed one after another. To maintain the ridged state, it is not possible to remove them all at once to maximize the use of light, and to avoid negative effects on the root system. The third is to wait until the end of fruit enlargement of the tomato head and then remove all the lateral branches. That is, when the fruit of the panicle grows to the size of the walnut, the water is wiped off with the topdressing fertilizer, and all lateral branches are removed by hand. This can greatly increase the nutrient flow to the fruit, which is beneficial to fruit enlargement.
Advantages and Disadvantages of Early Night-Pruning and Pruning Early Pruning and Pruning Techniques use the natural growth of tomatoes to overcome the technical prejudice. By early eradication, the tomato can make full use of sunlight and promote the development of early roots, which is beneficial to the entire fertility of tomatoes. The period of nutrient accumulation promotes the transformation of the nutritional distribution of tomatoes at key moments, solves the problem of small end of ear and fruit in tomato production for a long time, and at the same time helps to solve the problem of premature tomato failure and lays a good foundation for high tomato yield. The disadvantage of this technology is that it takes more than 1-2 working days per acre more than the traditional pruning technology.
In short, the early-to-late treatment of tomato is not much time-consuming, but it can promote the root development of tomato seedlings, increase the number of roots and accumulation of photosynthetic products in the early stages of tomato growth, enhance growth, improve the ability of the root system to absorb nutrients during the fruiting period and tomato The total output is a practical technology with promotion value.
