Problems needing attention in eggplant seedling stage

Eggplant seedling stage is the most likely problem in the process of planting, at this time the seedling resistance is weak, once the problem is easy to cause dead seedlings, the following small series for everyone to sort out the eggplant seedling stage easy to appear problems and solutions, let's take a look.

1. Cotton blight

Eggplant cotton blight mainly damages fruit, stems and leaves and flower parts, most easily occurs in seedling stage, mainly damages stems, the pathogen of the disease belongs to oomycetes, the optimum temperature for pathogen growth is 28-30 degrees, the onset temperature is 30 degrees, the relative humidity of air is 85%, such temperature and humidity environment is suitable for spore formation, and the disease is easy to occur when the temperature is high and rainy and the humidity is high.

Control methods: In addition to strengthening cultivation management, the key is chemical control. Protective fungicides can be sprayed during early prevention. If symptoms occur, cymoxanil manganese zinc can be sprayed for control.

2. Married interface disease

In order to prevent verticillium wilt and fusarium wilt, many eggplant are now grafted, but the grafted joint has become a way for bacteria to invade. Married interface disease, planting buried too deep or too high plastic film coverage, married interface humidity is large, but also easy to cause bacterial infection, serious cause eggplant wilt Yan, dead trees. When the indoor air humidity is relatively large, the marriage interface will condense dew, giving germs the opportunity to take advantage of.

Solution: Therefore, attention should be paid to the protection of the marriage interface to prevent disease occurrence. When grafting, the rootstock stem should not be too low, the planting should not be too deep, and the plastic film covering should pay attention to exposing the marriage interface. In this way, the humidity of the joint is low, and the infection of germs is reduced. For plants without disease, broad-spectrum fungicides can be sprayed on the stems or adjusted into paste to smear the stems.

3. Physiological boron deficiency

One of the reasons for boron deficiency in eggplant seedling stage is insufficient boron fertilizer supplement, and the other is to worry about the growth of eggplant, so water control methods are adopted to affect boron absorption.

Control method: appropriate amount of boron fertilizer in the base fertilizer is conducive to the establishment of strong roots in the seedling stage of eggplant. Generally, 0.5-1 kg of boron fertilizer is added when the base fertilizer is applied, so that the boron requirement of eggplant can be met. After eggplant planting, timely spray boron-containing foliar fertilizer, spray twice continuously, and pay attention to timely watering to avoid uneven drought and flood.

The above is the eggplant seedling needs to pay attention to the problem introduction, hope to help you, want to know more related knowledge, please pay attention to us.
