Ginger is an important export-oriented vegetable in China. However, many farmers have followed the traditional habits in production management. They do not follow the fertilizer rules. The fertilization period is too concentrated, and the former is heavy and light. The result is that the early ginger seedlings are long and the nutrient loss is large. Waste, late fat deficiency, plant yellowing premature aging, yield reduction; some apply partial nitrogen fertilizer and nitrogen fertilizer, too much, do not pay attention to the combination of phosphorus, potassium and other elements, the results not only cause the loss of nitrogen nutrients and Waste, and the imbalance of nitrogen, phosphorus and potassium ratios often lead to adverse consequences such as long plant growth, weak disease resistance, and decreased quality of ginger, which affects farmers' economic benefits. In fact, the rhizome of ginger absorbs less nitrogen, phosphorus and potassium during seedling stage, and the absorption of phosphorus increases slowly during the vigorous growth period, and the demand for nitrogen and potassium increases sharply, especially in the early stage of vigorous growth. The second is nitrogen fertilizer; while in the middle and late stages of vigorous growth, the nitrogen fertilizer is more than potassium fertilizer, and the potassium fertilizer is more than phosphate fertilizer. Autumn is the time when ginger needs the most fertilizer. Therefore, in production, formula fertilization according to the fertilizer requirement of ginger, timely application of nitrogen fertilizer can help increase production.
The fertilization of ginger is divided into base fertilizer and top dressing. The principle of “applying sufficient base fertilizer and timely fatning†should be adopted. The base fertilizer is divided into organic fertilizer, cake fertilizer and chemical fertilizer. The organic fertilizer is applied in combination with the ground preparation before planting. Generally, 5-8 cubic meters of high-quality decomposed chicken manure is applied per acre, and tillage is applied after application; cake fertilizer and fertilizer are concentrated in the ditch, which will be crushed before sowing. The cake fertilizer and fertilizer are concentrated into the seeding 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 the base fertilizer, it is generally carried out three times. The first top dressing is carried out when the seedling height is about 30 cm and there are 1-2 branches. This time, the topdressing is mainly based on nitrogen fertilizer, and 20 kg of ammonium sulfate or diammonium phosphate can be applied per mu.
Before and after the beginning of the autumn, Jiang Miao was in the period of three scorpions. This is the turning point of ginger growth and the turning point of nutrient absorption. This topdressing is very important for the formation of ginger. Since then, plant growth has accelerated and a large amount of nutrient accumulation has been formed. Product organ. Therefore, the demand for fertilizer and water is increasing. In order to ensure high yield of ginger, the second top dressing is carried out in combination with the removal of ginger grass or the removal of ginger shed before and after the fall. This top dressing plays an important role in promoting hair growth and rhizome enlargement. It requires a large amount of fertilizer, a comprehensive nutrition, and a long-lasting fertilizer effect. This time, the topdressing fertilizer should be combined with the fertilizer fertilizer with long-lasting fertilizer and quick-acting fertilizer. Use 70-80 kg of crushed cake fertilizer per acre, or 500 kg of decomposed high-quality manure, plus 25-50 kg of compound fertilizer. Open a fertilization ditch at the side of the plant at 15-20 cm from the base of the plant. Into the ditch, and mix with soil and fertilizer, then cover the soil, seal the soil, and finally pour the water.
In the first ten days of September, when the ginger seedlings have 6-8 tillers, it is the period of rapid expansion of the rhizome. The third top dressing can be carried out according to the growth of the plant, which is called “replenishing fertilizerâ€. On the one hand, the topdressing tends to make the stems and leaves flourish. Maintain strong assimilation ability, so that ginger roots can be rapidly inflated; on the other hand, it can prevent defermentation in the late growth stage and lead to premature senescence of stems and leaves, affecting yield. For the Jiangtian with low growth or growth and the Jiangtian with low soil fertility, in this period, quick-acting fertilizers, especially potassium and nitrogen fertilizers, can be applied to ensure the nutrients needed for rhizomes. Generally, 25-30 kg of compound fertilizer per mu is applied. 25 kg of ammonium sulfate, the soil fertility is high, and the plant growth is strong, the ginger field can also be applied less or not as appropriate, so as to avoid stems and leaves, affecting the expansion of the rhizome.
