Ginger Fertilizer
In the fall, it is the time when the ginger needs the highest amount of fertilizer. Therefore, in terms of production, formula fertilization according to the fertilizer requirement law of ginger, timely application of nitrogen fertilizer will help increase production.
The fertilization of ginger is divided into basic fertilizer and top dressing, and the principle of “giving enough base fertilizer and timely top dressing†should be adopted. The basal fertilizer is divided into organic fertilizer, cake fertilizer and chemical fertilizer. The organic fertilizer is applied in combination with site preparation before sowing. Generally, 5~8 cubic meters of chicken manure is decomposed per acre, and plowing is applied after application; the application of cake fertilizer and fertilizer concentrates ditch is to smash it before sowing. The cake fertilizer and chemical fertilizer are applied into the sowing ditch, generally 75-100 kg of cake fertilizer per acre, 50 kg of nitrogen, phosphorus and potassium compound fertilizer or 25 kg of urea, superphosphate, and potassium sulfate. In addition to applying base fertilizer, three top dressings are generally performed. The first top dressing was performed at a seedling height of about 30 cm with 1 or 2 branches. The topdressing fertilizer is dominated by nitrogen fertilizer. Apply ammonium sulfate or diammonium phosphate 20 kg per acre.
Before and after the beginning of the autumn, Jiang Miao was in the period of the SanJieJie, which was a turning point in the growth of ginger and also a turning point for the absorption of nutrients. This topdressing was very important for the production of ginger. Since then, the growth of plants has accelerated, and large amounts of accumulated nutrients have formed. Product organs. Therefore, as the demand for fertilizer and water increases, in order to ensure high yield of ginger, it is necessary to combine the removal of ginger grass or demolition ginger shed before and after the beginning of autumn to perform the second topdressing.
This topdressing plays an important role in promoting tree growth and root enlargement. It requires that the fertilizer be large in quantity, the second is complete nutrition, and the third is long-lasting fertilizer. The top dressing should be combined with a long-lasting manure fertilizer and quick-release fertilizer. Use 70 to 80 kg of crushed cake fertilizer per acre, 500 kg of dried manure, and 25 to 50 kg of compound fertilizer. Open a fertilization ditch at the side of the ginger seedling 15 to 20 cm from the base of the plant and spread the fertilizer. Into the ditch, and mixed with soil and fertilizer, and then cover the ditch, soil, and finally drenched water.
