How to fertilize ginger during the swelling stage? Key points of planting techniques explained
How should ginger be fertilized during the swelling stage? Please give guidance. Starting from late July to early August, the ginger rhizomes enter the swelling stage, which is the most critical period for yield formation. If nutrient supply is insufficient at this time, it will affect rhizome swelling, making the rhizomes thin and small, not plump, and yield will drop significantly.

How should ginger be fertilized during the swelling stage? Please give guidance
Starting from late July to early August, the ginger rhizomes enter the swelling stage, which is the most critical period for yield formation. If nutrient supply is insufficient at this time, it will affect rhizome swelling, making the rhizomes thin and small, not plump, and yield will drop significantly. Therefore, during the ginger rhizome swelling stage, fertilization management should be strengthened to ensure timely, sufficient, reasonable, uniform and comprehensive nutrient supply, so that the ginger rhizomes can fully swell, increase yield and achieve a good harvest.
The specific fertilization method is as follows:
During the ginger rhizome swelling stage, a root fertilizer must be applied once every 15 days, each time applying 75-80 kg of ternary (15-15-15) compound fertilizer, 15-20 kg of potassium nitrate, and 10-15 kg of monopotassium phosphate per mu, diluted with clean water or biogas slurry at 50-60 times and poured on. At the same time, spray a mixture of 0.1% magnesium sulfate, 0.3% urea, 0.5% monopotassium phosphate, 600 times amino acid compound microfertilizer, and 1000 times KT-30 (forchlorfenuron) on the leaves once every 10 days, spraying continuously 8-10 times. Spray all leaves evenly until water droplets begin to drip down. Supplement nutrients from the leaves, improve the nutritional level of the leaves, delay premature senescence of the plants, help the ginger rhizomes swell, and significantly increase yield.
