The Latest Tutorial on Field Management Techniques for High-Yield Ginger
If you want high yields when 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, and this has a huge impact on both the yield and quality of the ginger. So how should we carry out 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 transplanted and thinned later after the early sowing, this still has a certain impact on the growth of the ginger. Normally, when we grow ginger, the row spacing is about 35 cm and the plant spacing is about 25 cm. Of course, if the soil quality of the planting site is poor, you can also plant appropriately more densely.
2. Shade and temperature management
After sowing ginger, we need to build a shade shed. Of course, it can also be built after the ginger seedlings have all emerged, but the purpose in either case is to reasonably regulate light intensity and keep the shading effect at around 60 percent. By the time July and August come, the shade shed should be removed in time. Also, during the growing 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 growing period is best kept between 18 and 25 degrees.
3. Water management
Ginger likes moisture, fears waterlogging, and is not drought-tolerant, so regulating field moisture during the growing 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, changes in the weather, and the wet or dry condition of the soil. In areas with good rainfall, generally only four waterings are needed each year, namely at emergence, after full emergence, during the growing period, and during the tuber enlargement stage. 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 done by intertillage, which not only improves soil aeration but also enhances nutrient uptake and prevents nutrients from being absorbed 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 growing period of the ginger.
5. Earthing up 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, late-stage supplementary fertilizer, and foliar fertilizer. The amount of fertilizer applied gradually increases as it grows. Early fertilizing is generally mainly nitrogen fertilizer, while later on the use of phosphorus and potassium fertilizers and cake fertilizer needs to be increased, which can promote the enlargement of the rhizome. Also, when the rhizome is swelling, we should earth up appropriately to prevent the rhizome from being exposed above the ground.
That is all the content the editor wants to share with everyone today. Of course, field management also includes pest and disease control, especially ginger blast, anthracnose, white grubs, and ginger stem borers, so we should prepare for prevention and control in advance.
