Fresh ginger

1. Nutritional characteristics

The whole process and cost of ginger is a vegetative growth process, according to its growth characteristics can be divided into germination period, seedling period, vigorous growth period and rhizome dormant period. The germination period (from early April to mid to late May), from the germination of seed ginger buds to the first ginger leaves, it takes 40 to 50 days for the germination period, and the growth rate of this period is small, mainly relying on the growth and germination of seed ginger nutrients; Seedling stage (mid to late May to early August), from the beginning of leaf spread, to have two large lateral branches, that is, "three branches" period, it takes 65 to 75 days, this period begins to rely on the plant to absorb nutrients, slow growth; Vigorous growth period (early August to mid-late October), from three branches to harvest, is the vigorous growth period of stems, leaves and roots, which takes 70 to 75 days; Rhizome dormancy, usually before the onset of frost, forcing the rhizome into dormancy and safely overwintering.

2, need fertilizer characteristics

In the whole growth period of ginger, the amount and proportion of nitrogen, phosphorus and potassium required vary due to different factors such as soil, climate, varieties and planting methods. For every 1000 kg of fresh ginger, pure nitrogen (N) 5 ~ 7 kg, phosphorus (P2O5) 1 ~ 1.5 kg, potassium (K2O) 10 ~ 12 kg.

The growth of seedlings was small, and the absorption of nitrogen, phosphorus and potassium was also small. After three-prong, the growth of plants increased rapidly, the number of branches increased, the leaf area expanded rapidly, the rhizomes grew vigorously, and the fertilizer demand increased rapidly.

In addition to the need for nitrogen, phosphorus and potassium fertilizer, ginger also has certain requirements for boron, zinc, calcium, magnesium and other trace element fertilizer, adding boron and zinc, can promote the growth of plants, leaf area than ANI to reach, the number of branches increased, and ginger ball becomes larger, round, bright and shiny skin color, good quality.

3. Fertilization technology

It is recommended to apply strong high nitrogen and high potassium special formula fertilizer (15-5-20), which should be combined with ploughing into the soil or furrow covering.
