Matters needing attention in eggplant seedling stage

The seedling stage is the most common problem in the process of eggplant planting, when the resistance of the seedlings is weak, and once there are problems, it is very easy to cause dead seedlings. The following editor will sort out the problems that are easy to appear in the eggplant seedling stage and their solutions. Let's take a look.

1. Cotton blight

Eggplant cotton blight mainly harms fruits, stems, leaves and floral organs, and is most likely to occur at the seedling stage, mainly harming stems. The pathogen of the disease belongs to egg bacteria, the optimum temperature for bacteria growth is 28-30 degrees, the onset temperature is 30 degrees, and the air relative humidity is 85%. This temperature and humidity environment is suitable for the formation of bacterial spores, and the disease is easy to occur in high temperature, heavy rain and high humidity.

Prevention and control methods: in addition to strengthening cultivation management, the key is chemical control, early prevention can be sprayed with protective fungicides, if there are symptoms, can be sprayed with frost urea cyanide manganese zinc and other prevention and control.

2. Graft interface disease

In order to prevent Verticillium wilt and Fusarium wilt, many eggplants are grafted, but the grafting interface after grafting has become a way for bacteria to invade. Grafting mouth infection, planting is too deep or plastic film cover is too high, the graft interface humidity is high, but also very easy to cause bacterial infection, serious eggplant wilt, dead trees. When the indoor air humidity in the shed is high, the graft interface will condense dew, which can be taken advantage of by the bacteria.

Solution: therefore, attention should be paid to the protection of the grafting interface to prevent the occurrence of diseases, the rootstock stalk should not be too low, the planting should not be too deep, and plastic film mulching should be paid attention to expose the grafting interface. In this way, the humidity of the grafting interface is low, and the bacterial infection is reduced. for the plants without disease, the stalks can be sprayed with broad-spectrum fungicides or adjusted to paste.

3. Physiological boron deficiency

One of the reasons for boron deficiency in eggplant seedling stage is the lack of boron fertilizer supplement, and the other is to worry about eggplant growth and adopt the method of water control, which affects the absorption of boron element.

Control methods: proper application of boron fertilizer in the base fertilizer is beneficial for eggplant to establish a strong root system at the seedling stage. Generally, 0.5-1 kg boron fertilizer is added when basal fertilizer is applied, which can meet the demand for boron in eggplant. After the eggplant is planted, the foliar fertilizer containing boron is sprayed twice in a row, and attention should be paid to timely watering to avoid uneven drought and flood.
