After the beginning of autumn, ginger fields in various places experienced large soil cultivation and frequent occurrence of diseases after waterlogging, which brought severe tests to ginger. After actual experience research and analysis, the countermeasures are proposed for the reference of the majority of Jiang farmers. 1. What is the cause of red ginger leaves? How to manage protection? 1. Some ginger farmers reported that the lower leaves of ginger had redness, and the effect of spraying medicine was not ideal. In this case, the excessive use of nitrogen fertilizer after large soil cultivation often smokes the lower leaves. After large soil cultivation, spray the leaves with 30 ml of refined fertilizer and 30 kg of water to relieve the fertilizer damage. Pay attention to spray in the evening and avoid sun exposure. 2. Some Jiang Nong said that his ginger had red leaves before the soil was cultivated, especially after the rain. This situation is often caused by anthracnose, which is spread by rain and causes the disease to spread from point to surface. You can use the agent 45% prochloraz 20 ml + 25% pyraclostrobin 20 ml + calcium plus magnesium 20 ml to 30 kg of water sprayed with leaves for control. 2. How to fertilize after large soil cultivation? Do not water immediately after large soil cultivation, and then small water after two days. When watering, use 1 bucket/mu of seaweed and chitin with water to promote ginger to repair damaged roots. 5~7 days after the soil is cultivated, water 1 bag/mu of high-potassium water-soluble fertilizer and 1 bucket/mu of chubby. At present, ginger pieces are rapidly expanding, and the amount of fertilizer required is soaring. This is a critical period that determines the yield and quality of ginger pieces. The swelling, color and branching of ginger need not only high potassium, but also other nutrients. Therefore, it is necessary to frequently spray and flush fine fertilizer to prevent lack of nutrients. 3. How to prevent ginger plague and rotten neck after rain? Some ginger fields have a lot of water, in addition to timely drainage of waterlogging, they must also focus on the prevention and treatment of ginger blast and rotten neck. First of all, when the rain subsides, "waterlogging" with clear water will increase the oxygen content of the soil and promote capillary root respiration. When watering, rinse with water once per mu with 1000 ml of genimelikang + 40 grams of hymexazol to prevent the spread of diseases.
