The cause of the latest ginger rotten ginger

Ginger is an important seasoning vegetable, the market price is relatively high, many growers grow ginger to increase income, but ginger mainly harvest stems grow in the ground, for some reasons, ginger is easy to rot in the growth process. Now I will mainly introduce to you the main reasons for ginger rot and how to prevent it. How to prevent rotten ginger.

1. Excessive fertilization

Ginger is resistant to fertilizer, but as long as it meets the needs, some farmers apply too much chemical fertilizer and do not apply fertilizer blindly. In general, in a growth cycle, they will top fertilizer twice in addition to base fertilizer, and once when the plant grows to 30 to 40 centimeters, it mainly applies farm manure. 800 kg per mu. Another time, when ginger began to take root in summer, 1000 kilograms of farm manure was applied per mu. After that, do not topdressing, topdressing too much, the root system can not absorb, in the soil will cause rotten roots. Fertilize according to the need to fertilize, fertilization concentration is not too high, apply more farm manure.

2. Improper fertilization

Some chemical fertilizers and compound fertilizers have high concentrations, do not dissolve in water, are not diluted or are too close to the rhizome. Burying chemical fertilizers in the ground after applying chemical fertilizers will hurt the roots. Less chemical fertilizer, farm manure uses poultry fertilizer. Poultry manure is so hot that it burns the roots and rots away as soon as it comes into contact with water. Therefore, less application of chemical fertilizer, application of chemical fertilizer should be far away, whether to cover or bury.

3. Disease caused

The main diseases of rotten ginger are ginger plague, which is mainly infected by seeds and soil, and ginger will rot after infection. Therefore, 50% carbendazim 800-fold solution, 0.2% potassium dihydrogen phosphate, 0.2% borax and 800-fold alum solution can be used to soak the seeds; 60 kg of agricultural potassium carbonate per mu can be used for soil disinfection treatment; 600-fold solution of poisonous alum is used for root irrigation treatment when field diseases occur.

4. High temperature and high humidity

When the ginger rhizome grows in summer, the temperature is very high, and there are many Rain Water in most areas. if the planting land is relatively low, the soil is sticky, and the water retention is too good, it will be wet and hot after heavy rain. The rhizome can't breathe and it's easy to rot. Therefore, it must be planted in places where the groundwater level is lower, in high places where drainage is unobstructed, and on flat land, multiple drainage channels must be dug, timely drainage, and plant ash must be scattered to absorb moisture.

Ginger rotten ginger is mainly due to the harm of bacteria, or the impact of the natural environment, so we must try our best to create a good growth environment, good growth environment, and there are many fewer germs. The soil must be disinfected to purify the growing environment.
