When is the best time to plant ginger? A detailed guide to solving yellowing leaves

Ginger is a common seasoning in daily life. Generally, when stewing soup or stir-frying, many people add some to it, not only for seasoning but also to enhance the taste, so it is planted in many regions. So when is the best time to plant ginger? What causes the leaves to turn yellow?

1. Introduction to ginger:

1. What ginger varieties are there?

Lujiang No. 1, Shannong Dajiang No. 1, Laiwu Dajiang, Tongling White Ginger, Sichuan Zhugen Ginger.

2. Where is the best ginger from?

There are many ginger-producing areas. In China, it is cultivated in Shandong, Yunnan, Sichuan, Guizhou, Chongqing and other places. Among them, the Weifeng Dajiang produced in Qingzhou, Shandong is particularly well known, and Laiwu City, Shandong is the largest export base, selling as far as the Middle East, Japan, the United States and other places.

2. When is the best time to plant ginger?

Ginger is generally sown from late April to early May, but because temperatures vary from place to place, the planting time differs slightly. For example, in Hunan, Wuhan and other central China regions, it can generally be planted in early April; in Yunnan, Guizhou, Sichuan, Chongqing, Tibet, Ningxia, Shaanxi, Gansu and other places, it can generally be planted in March, so the specific time should be determined according to the local climate. In one sentence: if the temperature is around 25-30 degrees, it can be planted.

3. What causes ginger leaves to turn yellow?

Cause 1, temperature too high: Ginger does not have high temperature requirements; it can generally grow at around 18-20 degrees. If the temperature is too high, yellow leaf disease will occur and cause the leaves to turn yellow.

Solution: After planting ginger, remove the plastic film in time to avoid excessively high temperatures and the occurrence of yellow leaf disease. At the same time, during high-temperature summer weather, provide appropriate shade.

Cause 2, humidity too high: Ginger is afraid of moisture. Generally, in rainy weather, if water accumulates, the plants will be infected by bacteria, causing the leaves to turn yellow.

Solution: During continuous rain or heavy rain, carry out drainage measures in time.

Cause 3, the field is too dry: Ginger has weak drought resistance. If it is not watered for a long time and the soil becomes compacted, the plant leaves will also turn yellow.

Solution: Water in time, but do not water too much. At the same time, appropriately increase or reduce the number of waterings according to the dryness and moisture of the soil.

Cause 4, improper fertilization: Ginger does not have high fertilizer requirements. Generally, applying an appropriate amount of compound fertilizer or organic fertilizer is enough, but if too much is applied or no fertilizer is applied for a long time, the leaves will turn yellow.

Solution: Reasonably apply some compound fertilizer or organic fertilizer, but do not apply too much, and the ratio should be appropriate to avoid burning the seedlings. At that time, the soil can be shallowly loosened to improve soil aeration.

Cause 5, disease factors: During the ginger growing period, diseases such as yellow leaf disease and ginger blast will occur, and these diseases will cause the leaves to turn yellow.

Solution: Use carbendazim agent in time for spraying control. For those with relatively severe disease, pull them out in time and destroy them in time to prevent the disease from occurring.

The above is a detailed introduction to the planting time of ginger and the solutions to the yellowing leaf phenomenon. I hope it is helpful to everyone.
