Ginger has a long growth period and requires a large amount of fertilizer. It is a fertilizer-loving crop. During the growth process of ginger, the rhizomes gradually swell, and they need to continuously absorb nitrogen, phosphorus, potassium, calcium, magnesium and other nutrients from the soil. Therefore, in addition to applying sufficient base fertilizer for high yield of ginger, it is also necessary to apply fertilizer in stages, especially "three-branched fertilizer", to meet the nutrient requirements of ginger growth.

1. Basic fertilizer: organic fertilizer is the main method, and chemical fertilizer is the supplement It is recommended to use 100-200 kg of gold-titanium microbial inoculants (particles) per mu, plus 20-25 kg of gold-titanium nitrosulfur 15-15-15 compound fertilizer or ecological grade nitrosulfur 15-15-15 compound fertilizer.

2. Top dressing: When ginger grows to have two larger side branches, the side branches and the main stem are similar in height (that is, the three-branched period), after this period, the above-ground and underground rhizomes enter the vigorous growth period at the same time, which is mainly manifested as the growth rate. On the one hand, a large number of branches occur, and the number of leaves increases accordingly. On the other hand, the underground rhizomes expand rapidly and accumulate a large amount of nutrients, which requires a large amount of fertilizer and water. To ensure the high yield of ginger, top dressing should be carried out. At this time, fertilization is called "three-branched fertilizer" or "transition fertilizer". This top dressing plays an important role in promoting growth and rhizome enlargement. In this period, the amount of topdressing should be large, combined with soil cultivation, and combined with the application of microbial agents containing active bacteria to improve the soil aggregate structure and prevent soil-borne diseases.

Topdressing in the order of "small training first, then big training", that is, 1/3 of the total topdressing from July 5th to 20th, and one small topdressing; topdressing the remaining 2/from 5 days to 15 days before the beginning of autumn 3. Carry out a large soil cultivation.
