What to Do About Vegetable Seedling Death? Detailed Prevention Measures

During production and cultivation, vegetable seedling death often occurs, seriously affecting the growth of vegetables, and there are quite a few causes of vegetable seedling death. So, in order to deal with vegetable seedling death, what should we do during cultivation? Let's take a look together.

1. Bacterial fertilizer to prevent pests and diseases

Before vegetable cultivation, the greenhouse and garden soil must first be prepared. In recent years, soil-borne diseases have become increasingly serious. To prevent the occurrence of diseases, in addition to plowing the land and applying bacterial fertilizer and dipping the roots in pesticides, it is also necessary to often adopt the method of applying pesticides or bacterial fertilizer in holes to promote roots and prevent diseases. When vegetables are just planted, underground pests like to gnaw on the roots, causing the aboveground seedlings to wither and, in severe cases, die. Biological bacterial fertilizer can not only provide fertility for vegetable growth and add beneficial bacteria to prevent soil-borne diseases, but also improve the stress resistance and lodging resistance of vegetables.

2. Organic fertilizer to prevent fertilizer damage

Excessive application of chemical fertilizers, overly concentrated application, or single application of a certain chemical fertilizer will greatly increase the occurrence of fertilizer damage, causing root burn and seedling burn, leading to vegetable seedling death and plant death. Therefore, in order to prevent fertilizer damage, it is necessary to reduce the application amount of chemical fertilizers and increase the application of biological bacterial fertilizer and organic fertilizer. However, it should be noted that organic fertilizer must be fully decomposed, otherwise it will also cause fertilizer damage. Especially when using farmyard manure such as chicken manure and duck manure as base fertilizer, it must first be subjected to high-temperature greenhouse sealing to make it fully decomposed before use.

3. Planting depth

Vegetable seedling death due to diseases occurs from time to time, mainly because of stem rot and phytophthora blight. The frequent occurrence of causes after vegetable planting is greatly related to planting depth. If vegetables are planted too deep, the stem base of the seedlings is buried in the soil. In the early stage, there is less water absorption, the outside temperature is too high, and water evaporates quickly, resulting in excessively high temperature at the stem base. The epidermal tissue at the stem base is damaged, creating favorable conditions for pathogens. Therefore, when planting vegetables, attention must be paid to appropriate depth, and the best solution is ridge cultivation.

4. Watering should be moderate

Excessive watering will cause root rot. In addition, water temperature also has a direct impact on root physiological activity. If the difference between soil temperature and water temperature exceeds 5 degrees, then after watering, it will cause a sudden change in soil temperature and damage the root system, instead affecting the root system's absorption of water and causing physiological drought. Therefore, it is best to irrigate when the water temperature and soil temperature are close. In autumn and winter, it is best to first store the water indoors for a period of time, or add warm water, so that the water temperature rises to 15-20 degrees before irrigating. The watering time is generally after 10 a.m. and after 4 p.m. Remember not to water at night, as this will increase the probability of disease infection and freezing damage.
