Ginger into autumn and fertilize

Ginger is more resistant to fertilizer and has a longer growth period. It should adopt the principle of “applying sufficient base fertilizer and multiple topdressing”. Ginger has different growth characteristics and characteristics of fertilizer absorption in its different growth stages. It should be topdressed in stages to meet the nutrient requirements of ginger growth.
Liqiu is a turning point in the growth of ginger and a turning point in the absorption of nutrients. Therefore, after the fall, the second round of topdressing should be combined with the removal of ginger grass or the removal of the ginger shed. It is also called “big top dressing” or “transfer fertilizer”. This top dressing plays an important role in promoting root enlargement and obtaining high yield. This top dressing requires the combination of farmyard manure with quick-acting fertilizer and quick-acting fertilizer, 70-80 kg of crushed cake fertilizer per acre, or 3000 kg of decomposed high-quality manure, plus 15-20 kg of compound fertilizer or ammonium sulfate. On the north side of the ginger seedling, a fertilization ditch is opened about 15 cm from the base of the plant, and the fertilizer is applied into the ditch to mix the soil and the fertilizer, and then the soil is sealed.
In the first ten days of September, when there are 6-8 branches in Jiangyan, it is also the period of rapid expansion of the rhizome, which can be fertilized according to the growth of the plant. The general fertilizer field applies compound fertilizer or ammonium sulfate 20-25 kg per mu; The ginger field with better plant growth can also be applied less or not as appropriate, and the stems and leaves are not long, which affects the expansion of the rhizome.
At present, in the cultivation of ginger, there are two types of fertilization biases that should be noted. First, the fertilizer is not applied as required. The fertilization period is too concentrated. The former is heavy and light. The result is that the early ginger seedlings are long, the nutrient loss is large, the fertilizer is deficient in the late stage, the plants are yellow and premature, and the yield is reduced. Second, the application of nitrogen fertilizer and nitrogen fertilizer is too much, and it does not pay attention to the combination of various elements such as phosphorus and potassium. The result is not only the loss and waste of nitrogen nutrients, but also the imbalance of nitrogen, phosphorus and potassium. Caused by the long-term growth of the plant, weakened disease resistance, and decreased quality of ginger. (Source: China Fertilizer Network)
