Technical points of Tomato Seedling Replenishment after death

The main results are as follows: 1. Clear the planting point. After the tomato died, the pathogens of the original planting holes are bound to increase. It is necessary to clean up the planting holes and kill the pathogens in order to ensure that the re-replenished tomato seedlings are no longer susceptible and dead. When planting acupoints, Yinfari, Kate and Xiangnong No. 4 can be mixed with water, each hole is more than 3-5 pairs, and the soil is soaked in the hole to achieve germicidal effect.

2. Root treatment of seedlings. Before planting, tomato seedlings need to treat their roots with chemicals to prevent pathogens from entering. In general, the roots of tomato seedlings can be soaked with chitin to sterilize and promote the roots of tomato seedlings.

3. Infuse medicine after planting. Within half a month after planting, it is an important period for the occurrence of the disease. before that, that is, 7-10 days after planting, it is when "the old force has gone, but the new force has not yet been born". If the tomato root is irrigated with medicine at this time, the probability of dead trees can be greatly reduced. Root irrigation can use Prike, chlorpromazine, combined with chitin, chitosan oligosaccharides and so on, to promote the root culture effect is better.

The second peak of tomato death is near the tomato fruit setting, at this time the tomato is larger, after the death of the plant, the loss is heavy, when there is a problem, it is best to first use medicine to deal with the dead plant and the surrounding plants, in a round radiation around the drug, to avoid the disease of healthy plants. If the dead trees occur sporadically, you can leave more branches on both sides of the tomato, or carry out double-dry pruning to make full use of the space after the death to avoid a significant reduction in yield.

Note that dead tomato diseases are mostly spread by running water, after the occurrence of dead trees, do not immediately watering, especially flood irrigation, but also try to avoid Rain Water into the shed.
