Winter tomato pruning for more production
After the winterization of tomato cultivation, the plant load gradually increased as the outside temperature decreased. To the harsh winter shed environment is not conducive to the growth and development of tomatoes, low temperature and poor light caused by poor nutritional status of tomato plants, but plant growth, fruit development, flowering and other dietary competition increasingly fierce, often causing plant weakness, empty ear, small fruit development, Resistance and other adverse reactions. In order to solve this problem, we adopted the method of digging up the head of wintering cultivated tomatoes before winter to reduce the consumption of nutrients during the winter period, so that this series of contradictions has been alleviated. This kind of pruning method is used in the winter tomato fields in the southwest of Shandong Province. Has been widely used.
Specific method of operation: During the snowy season, the wintering tomato 5~6 spikes will be picked up and the side branches on the tomatoes will be cleaned completely, and after picking the heart, there will be a planned selection to leave the second and third leaves from the top second fruit. The collateral branch in the results of the culture branch, usually leaving two lateral branches per plant, until the main vine tomato first and second ear fruit harvest, the lateral branch into the flowering period, to carry out a replanting treatment, so that the plant distribution tends to be reasonable. At this time, it is almost spring. Temperature and ground temperature begin to rise. The plant growth gradually becomes stronger, which helps the plants to avoid the coldest winter, reduce nutrient consumption, and promote the growth of the main vine tomato fruit. The collateral retention of 5,6 panicle topping resulted in an increase in the total number of results and yields and yields of the tomato plants. The double-sided branching of the tomato for head-to-head cultivation correspondingly increased the number of tomato plants and increased the density of the leaves. . In spring, the prevention of leaf diseases such as leaf mold and spot blight should be strengthened.
