Causes of the latest death of ginger seedlings and preventive measures

The phenomenon of dead seedlings will occur in the process of planting ginger, which will seriously cut off ginger and cause huge economic losses to farmers, so what is the reason for the death of ginger seedlings? How to prevent it? Let's take a look at the detailed introduction with the editor.

1. Ginger blast disease

Many seeds do not go through disinfection measures, will carry a large number of bacteria, invade when the seeds germinate, but the seedlings have weak resistance and are very easy to occur. Or the soil will invade when the seeds germinate without strict disinfection and sterilization measures, resulting in the phenomenon of dead seedlings. 、

Prevention: after planting ginger is harvested, put it in the sun for a few days and place it at 20-30 degrees for a week to make the wound heal and reduce the incidence of ginger plague. Soak in borax solution, carbendazim and poisonous alum for 15-20 minutes before planting, completely eliminate the annual average, and avoid continuous cropping combined with soil preparation with 75-100 kg of quicklime per mu for disinfection. Diseased plants should be removed in time and quicklime should be sprinkled near the disease points.

2. Improper fertilization

When planting, many farmers think that the more fertilizer, the higher the yield, so blindly apply chemical fertilizer, partial application of nitrogen fertilizer, centralized fertilization, resulting in fertilizer damage of ginger, serious seedling death phenomenon.

Preventive measures: ginger fertilization should be based on mature farm manure, generally 3000 kg of farm manure, 30 kg of calcium superphosphate and 15 kg of potash fertilizer per mu as base fertilizer. In the later stage, topdressing was mainly organic fertilizer, combined with appropriate amount of chemical fertilizer, which increased the content of soil organic matter and promoted the expansion of rhizome.

3. Waterlogging damage

When the soil is overwatered or not drained in time after rain, the soil is very easy to agglomerate and cause waterlogging damage, and in the environment of high temperature and humidity, it is easy to rot the rhizome and lead to dead seedlings.

Preventive measures: when planting, we should choose the soil with deep soil layer, good permeability and good drainage, do not plant on clayey soil, dig a good drainage ditch during soil preparation, ensure smooth drainage, watering should not be watered too much at one time, and should be drained in time after rain.

4. Ginger borer

Ginger borer, also known as ginger borer, is a kind of omnivorous pest, which can be harmed from unearthed to harvested by larvae. After hatching for 2-3 days, the larvae will invade from the gap between leaf sheath and stem or heart leaves, and constantly drill upward to eat, resulting in hollow stems and hindering the transport of water and nutrients. A long time will lead to plant death.

Preventive measures: artificial capture can be used, because ginger borer is a borer, the effect of chemical control is not very good, and the resistance of aging larvae is strong, so artificial capture is advocated.

The above is the introduction of the causes of ginger seedling death and preventive measures. I hope it can help you. If you want to know more about it, please follow us.
