The causes and Solutions of slow Seedling after the latest vegetable planting

At present, most of the autumn vegetables have been planted. In the process of planting, we often find that the vegetables in the shed slow down quickly, and even some seedlings do not grow slowly, which not only affects the vegetable market time, but also affects the future yield. So what caused it? Let's get to know each other.

1. Insufficiently decomposed fertilizer causes seedling burning

Before planting, applying manure that is not fully decomposed will cause seedling burning. Some farmers think that seedling burning is caused by fresh chicken manure, while dried chicken manure is decomposed well and root burning will not occur. In fact, dried chicken manure is only chicken manure dried at high temperature. Without any decomposition measures, it will also appear burned seedlings. Therefore, fertilization must be fully decomposed before or after planting. If seedling burning has occurred, watering should be frequently carried out to dilute harmful substances released by fertilizer fermentation, and ventilation should be paid attention to avoid gas damage. At the same time, foliar fertilizer should be sprayed to supplement nutrients needed by plants.

2. Improper watering causes root rot

Many farmers think that vegetables as long as they are not in the late winter season, it doesn't matter whether the watering amount is large or small. In fact, too much watering at any time in the market will cause insufficient oxygen supply at the rhizosphere of vegetables, and when it is serious, it will rot roots. Once the vegetable retting root phenomenon occurs, its growth will be weak, not for a long time, serious will cause dead trees, so after planting vegetables must pay attention to watering, avoid watering too much, so as not to cause damage to the root system. For vegetables that have retting roots, they should be hoed in time to increase soil permeability. After the moisture in the soil is reduced, they should be irrigated with chitin to promote new root regeneration.

3. Rootknot nematode infection

Root nematode is the most common disease of vegetable seedling stage. Many farmers find that vegetables grow slowly when planting, and almost do not grow in the near future. They thought it was caused by burning seedlings with manure, but after pulling out the plants, they found that root nematode has been very serious. For root nematode control, prevention should be given priority to. In summer, high temperature should be taken to stew the shed, pesticide for root knot nematode control should be applied before planting, abamectin should be applied with water after vegetable planting, and sufficient measures should be taken to prevent root knot nematode in advance.

The above is an introduction to the reasons and solutions for slow seedling after vegetable planting. I hope it can help you. If you want to know more about relevant knowledge, please pay attention to us.
