Ginger has a long growing period and requires a large amount of fertilizer, which is a fertilizer and fertilizer-resistant crop. In the process of growing ginger, the roots and stems are gradually divided and the nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, etc. need to be continuously absorbed from the soil. Therefore, in addition to applying basic fertilizers, high yielding ginger must also be top-dressed, especially “three-fertilizer†to meet the growing demand for nutrients. Fertilization method: In this period, the amount of topdressing should be large, combined with soil cultivation, combined with the application of organic fertilizers with long-lasting fertilizer efficiency and quick-acting fertilizers, or applying organic-inorganic compound fertilizers alone. The total application amount is 80 to 120 kg per 667 m2 of high-quality organic fertilizer (such as Cailunzhongke and other organic fertilizers), and 100 to 120 kg of high nitrogen and potassium high-quality compound fertilizer; or 25% (12-4-9) of organic. Inorganic compound fertilizer 160-200 kg. In accordance with the order of “first small cultivation and then large cultivation,†the top-dressing will be applied in the order of 1/3 of the total amount applied on July 5 to 20 and a small soil will be used. The remaining 2/3 will be applied 5 to 15 days before the start of autumn. For a big earth. At this time, topdressing organic fertilizer is applied to improve not only the soil but also to ensure that the growth of the ginger is not deferred during the later period of growth.

Fertilization time: Regardless of the cultivation method, when the ginger has two large lateral branches and the height of the lateral branches is similar to the main stem (ie, the three-leaf stage), the above-ground and underground rhizomes enter the period of vigorous growth at the same time. The growth speed of performance has accelerated. On the one hand, a large number of branches have occurred, and the number of leaves has also increased accordingly. On the other hand, underground rhizomes have also rapidly expanded and accumulated a large amount of nutrients to form product organs, which has a large demand for fertilizer and water. In order to ensure that the high yield of ginger should be topdressing, this time fertilization is called "three manures" or "turnover manure." This top dressing plays an important role in promoting tree growth and rhizome enlargement. The time of fertilization is generally suitable from the early July to the early August, depending on the cultivation method. If the ginger reaches the standard of the third crop stage, it should be fertilized. It is generally a large shed earlier than a small arch shed, a small arch shed earlier than the mulch, and the mulch was earlier than the open ground. Remove ginger shading grass before applying fertilizer.
