Key Field Management Techniques for High-Yield Ginger
If you want a high yield from growing ginger, then its field management work is very important. If the field management work is not done well, ginger is very prone to disease, which has a huge impact on both the yield and quality of the ginger. So how should we carry out the field management work? Let's take a look together below.
1. Density management
When sowing ginger, we need to plan the density reasonably and must not plant too densely. Although seedlings can still be moved and thinned in the later stage after early sowing, this still has a certain impact on the growth of the ginger. Normally, the row spacing for planting ginger is about 35 cm, and the plant spacing is around 25 cm. Of course, if the soil quality of the planting site is poor, it can also be planted appropriately densely.
2. Shade and temperature management
After sowing the ginger, we need to set up a shade shed. Of course, it can also be set up after the ginger seedlings have all emerged, but the purpose in either case is to reasonably regulate the light intensity and keep the shading effect at around 60 percent. When July and August arrive, the shade shed should be removed in time. In addition, during the planting process we should pay attention to temperature regulation. A layer of plastic film can be used as mulch, but once the seedlings emerge from the soil, the film should be removed in time. The temperature during the growth period is best kept between 18 and 25 degrees.
3. Water management
Ginger has the characteristics of liking moisture, fearing waterlogging, and not being drought-tolerant, so regulating field moisture during the planting process is also very important. When growing ginger, timely watering and drainage need to be carried out according to the growth characteristics of the ginger, weather changes, and the wet or dry condition of the soil. If it is an area with good rainfall, generally only four waterings are needed each year, namely at emergence, after full emergence, during the growth period, and during the tuber enlargement period. But if the weather is not very good, appropriate adjustments need to be made.
4. Intertillage and weeding
Weeding for ginger is generally mainly shallow cultivation, which can not only improve soil aeration but also enhance nutrient absorption and prevent nutrients from being taken up by weeds. Intertillage and weeding are generally carried out together with watering, usually after watering, which can avoid the soil compaction caused by watering. It is best to carry out intertillage and weeding twice a year, respectively after emergence and during the growth period of the ginger.
5. Hilling and fertilizing
Fertilizing is a very important step in field management, and ginger has a large nutrient requirement, so fertilizing should be carried out according to its different growth stages. Fertilizing is generally divided into seedling fertilizer, growth fertilizer, rhizome swelling fertilizer, later supplementary fertilizer, and foliar fertilizer. The amount of fertilizer applied gradually increases with its growth. Early fertilizing is generally mainly nitrogen fertilizer, while later on it is necessary to increase the use of phosphorus and potassium fertilizer and cake fertilizer, which can promote the enlargement of the rhizome. In addition, when the rhizome is enlarging, we should properly carry out hilling to prevent the rhizome from being exposed above the ground.
That is all for what the editor wants to share with everyone today. Of course, field management also includes the prevention and control of pests and diseases, especially ginger blast, anthracnose, white grubs, and ginger borers, so we should make preparations for prevention and control in advance.
