Skillfully applying nitrogen fertilizer to ginger has high quality and high yield.
According to the law of ginger absorption, reasonable application of suitable varieties of nitrogen fertilizer can greatly increase the yield, improve the quality, increase the content of starch, protein and volatile oil of commercial ginger, and decrease the content of soluble sugar and cellulose. Among the four nitrogen fertilizers, ammonium bicarbonate, sodium nitrate, urea and ammonium nitrate, sodium nitrate had the best effect on the growth of ginger at seedling stage. In the middle and later stage, the application of ammonium bicarbonate had the best effect on increasing the yield of ginger and the content of volatile oil, starch and protein. In order to obtain high yield and high quality of ginger, we must pay attention to the application of nitrogen fertilizer on the basis of adequate application of phosphorus and potassium fertilizer. Generally, 30 kg ~ 40 kg nitrogen fertilizer is applied per mu, and ammonium bicarbonate or ammonium nitrate should be preferred for nitrogen varieties. In order to promote the early growth and rapid development of ginger seedlings, appropriate amount of sodium nitrate can be applied when phosphorus and potassium fertilizer is used as base fertilizer (accounting for about 20% of the total fertilizer application).

Cultivation techniques of Ginger softening
The softening cultivation of ginger is on the basis of normal cultivation, one is to increase the cultivation density and strengthen the measures of shading and cooling, so as to achieve the purpose of harvesting tender ginger. In this way, tender ginger not only has a long harvest time, high yield, but also fresh and crisp, thin skin and sparse skin, and has a delicate ginger flavor when eating. 1. Choose: choose those who have not planted ginger for 3 years in a row.

High-yield cultivation and management techniques of ginger
First, prepare before sowing. 1. Fine soil preparation and application of sufficient base fertilizer. The plots with fertile soil, good irrigation conditions and no ginger blast should be selected to avoid repeated cropping as far as possible. On the basis of winter ploughing, fine soil preparation should be carried out as early as possible in spring, so that the soil can be loosened and fruited without light and dark. Increase the application of organic fertilizer, with high-quality chicken manure, no disease and disability.
