The reason for ginger rot

Ginger is an important seasoning vegetable, the market price is relatively high, many growers plant ginger to increase income, but ginger mainly harvest stems grow underground, because of some reasons, ginger is easy to rot in the growth process, now mainly to introduce the main reasons for ginger rot and how to prevent and control. How to prevent ginger rot.

1. Excessive fertilization

Ginger is tolerant to fertilizer, but as long as it meets the needs, some farmers apply excessive chemical fertilizer, do not blindly fertilize, generally a growth cycle will be in addition to base fertilizer and then topdressing twice, once when the plant grows to 30 to 40 cm, topdressing mainly farm manure, 800 kg per mu. Another time in summer ginger began to take root, an mu of farm manure 1000 kg. After that, do not topdressing, topdressing too much, the root system can not absorb, in the soil will cause rotten roots. Fertilization should be applied according to needs, fertilizer concentration should not be too high, more farm manure.

2. Improper fertilization

Some fertilizers and compounds are concentrated in high concentrations, are not dissolved in water, are not diluted, or are applied too close to the rhizome, and burying the fertilizer underground after applying the fertilizer can damage the roots. Less fertilizer, farm manure, poultry manure. Poultry manure is too hot to burn the roots and rot on contact with moisture. So less fertilizer, fertilizer should be far away, do not cover or bury.

3, caused by disease

The main diseases causing rotten ginger are ginger plague, which is mainly carried by seeds and soil, and ginger will rot after infection. So you can use 50% carbendazim 800 times solution, 0.2% potassium dihydrogen phosphate, 0.2% borax, antivirus alum 800 times solution to soak seeds; use 60 kg agricultural potassium carbonate soil disinfection treatment per mu; use antivirus alum 600 times solution to irrigate roots for field diseases.

4. High temperature and humidity

In summer ginger rhizome growth season, the temperature is very high, and most areas have a lot of rain, if the planting site is relatively low, the soil is relatively sticky, the water retention is too good, after heavy rain, the water is humid and hot, the rhizome cannot breathe and easily rot. Therefore, it must be planted in a place with a lower groundwater level, planted at a high place with unobstructed drainage, and on the flat ground. It must excavate multiple drainage channels, drain water in time, and scatter plant ash to absorb moisture.

Ginger rotten ginger is mainly caused by the harm of germs or the influence of natural environment. Therefore, we must try our best to create a good growth environment. A good growth environment has fewer germs. The soil must be disinfected and the growing environment purified.
