Ginger planting technology: how to fertilize ginger?

How to apply fertilizer to plant ginger? What kind of micro-fertilizer does ginger need to add? Also asked experienced netizens to help introduce after the summary of many netizens, each production of 1000kg fresh ginger probably needs nitrogen 6.3kg, phosphorus 1.3kg, potassium 11.2kg, said that fertilization is the first way to improve the yield of ginger, so the farming network sorted out the fertilization methods of ginger, listed in detail below for netizens' reference. The fertilization principle of ginger: because the plant growth of heavy ginger is slow, the growth is small, and the seedlings absorb less nitrogen, phosphorus and potassium, but after the ginger grows to the three-strand stage, the plant growth rate is accelerated and the number of bifurcations is increased. the leaf area expands rapidly and the rhizome grows vigorously, so the amount of fertilizer required increases rapidly. Ginger base fertilizer: ginger base fertilizer can be combined with deep ploughing and soil preparation, applying high-quality rotten chicken manure 3000-4000kg, or high-quality ring fertilizer 4000-5000kg, pure sulfur-based compound fertilizer 50kg, zinc sulfate 1-2kg, borax 1kg per mu. Ginger topdressing: 1. Ginger strong seedling fertilizer: when the seedlings had 1-2 branches in the middle and first ten days of June, the secondary fertilizer was applied combined with watering, with an interval of 10-15 days, 15-20kg per mu. 2. Ginger jointing fertilizer: also known as turning point fertilizer (before and after the Beginning of Autumn). In the three-branch stage, ginger enters the vigorous growth period, which is the key period of topdressing, applying 70-80kg high nitrogen compound fertilizer per mu. 3. Extra-root fertilization of ginger: during the tuber expansion period, when 6-8 bifurcations appeared in the middle of September, the high nitrogen and potassium compound fertilizer 50kg was applied per mu with an interval of about 15 days. In the whole growth process, ginger not only needs to absorb a large amount of nitrogen, phosphorus and potassium from the soil, but also absorbs calcium, magnesium, zinc, boron and other trace elements. In the whole growing period, potassium is the most absorbed by ginger, followed by nitrogen, and other trace elements calcium, magnesium, zinc and boron. Calcium was mainly distributed in lateral branches and leaves, followed by rhizome, and less in main stem and main stem. Magnesium is mainly distributed in rhizome, and there is more magnesium in lateral branches and leaves, but less in main stem and main stem. The absorption of zinc by ginger is that the amount of zinc absorbed by ginger increases gradually with the continuous growth of the plant. Zinc plays an important role in the whole growth period of ginger. The absorption of boron by ginger is roughly the same as that of zinc. With the gradual increase of the number of boron absorbed by the plant, the absorption of the rhizome during the period of rapid expansion accounts for about 66% of the boron absorption and utilization during the whole growing period. Zinc fertilizer and boron fertilizer can usually be used as base fertilizer or extra-root topdressing. When zinc-deficient and boron-deficient ginger fields are used as base fertilizer, 1-2kg zinc sulfate and borax 0.5-1kg are generally applied per mu, which are evenly mixed with fine soil or organic fertilizer, and mixed evenly with the soil in the sowing ditch when sowing: for topdressing and foliar spraying, 0.05% 0.1% borax per mu is 50-70 liters per mu, which is sprayed three times in seedling stage, seedling stage and rhizome expansion stage.
