Pepper is rich in nutrients and is an essential seasoning vegetable. Many farmers have planted it. However, some farmers have recently reported that the survival rate of pepper seedlings after transplanting is low, and it is easy to die. In fact, this is caused by many factors, but farmers should pay attention to management in the process of transplanting. So, the survival rate of pepper seedlings after transplanting is low, what are the reasons? How to prevent it? Let’s take a look at it together and Xiaobian. Let's go.

1, pepper seedlings
The root of the pepper itself is shallower, which is different from the roots of tomato and cucumber, so it should be rooted at the time of seedling raising. Some peppers are not disinfected on the seedbed, and some have a long seedling period. At the same time, the pepper seedlings are infected with bacteria, and the pepper seedlings must have a low survival rate. Therefore, remind everyone that when buying pepper seedlings, you should not only look at the variety, but also observe the development of the root system, and have an understanding of the nursery base and the seedling supply unit.
2, soil salt is too high
The organic matter of cultivated land in China is generally low, and the suitable soil organic matter for planting pepper should reach more than 3%. The organic matter content is too low, the soil permeability is poor, and soil compaction is one of the reasons for the low survival rate of pepper seedlings. At the same time, the chicken manure is used without being fully decomposed, and urea and diammonium phosphate are used in excess, and the application amount of potassium fertilizer is small. Due to the long-term excessive use of nitrogen fertilizer, the degree of salinity exhibited by the soil is particularly serious. For such cultivated land, it is recommended to apply fully decomposed farmyard manure for ploughing when plowing the plot, and the pepper base fertilizer is mainly organic fertilizer, supplemented by compound fertilizer.
3, pepper for many years of continuous cropping
Peppers that have been planted for more than 3 to 5 years are prone to die. Some do not always grow peppers, but many of them are arranged in tomato, eggplant and cucumber. These mouthwashes are not conducive to the growth of peppers. If it can be rotated in the rotation with cabbage, rapeseed, broccoli and other liliaceae and onion, leek and other liliaceae vegetable crops, the survival rate will be greatly improved.

4, planting methods
Before the pepper is transplanted, the soil should be treated first. First, it can be disinfected by high temperature suffocation before transplanting. Second, carbendazim or copper sulfate mixed with zinc sulfate and then mixed into the ground. Generally, 4 kg of copper sulfate and 1.5 kg of zinc sulfate can be used per mu. It is recommended to apply more organic fertilizers containing microbial agents. Practice has proved that microbial agents can stimulate the rooting of peppers, inhibit the harmful bacteria to soak the pepper seedlings, and have an ideal effect on preventing soil-borne diseases.
5, too much watering
Generally, pepper seedlings should not be flooded with large water, and should be poured in small water and cultivated in high ridges. Excessive watering, excessive humidity, especially low-cultivation of pepper, prone to hypoxia and roots, resulting in rotten roots.
6, pest damage roots
Generally, the insects that are not fully decomposed with farmyard manure are seriously damaged. In particular, pests such as cockroaches, cockroaches, golden worms, and root-knot nematodes can directly cause root wounds of peppers, thereby aggravating the infection of the bacteria and causing dead peppers.
The above is the reason for the low survival rate of pepper seedlings after transplanting and preventive measures. Farmers should pay attention to management during the process of pepper transplanting, avoid the above reasons, increase the survival rate of pepper seedlings, and avoid the death of pepper.
