How should ginger be grown? Ginger has many uses in both food and medicine. How is ginger grown? What are the cultivation techniques for ginger? How can you grow ginger well? Then let's take a look at the following article on ginger cultivation techniques together, so you can learn more about agricultural science and technology knowledge. We hope it will be helpful to you.
How to Treat Ginger Before Sowing
Sun-drying the seed: Spread the selected whole ginger seed pieces in a single layer in a sheltered, sunny, dry and warm place on a sunny day. Spread them out at 8-9 am each day and bring them back in at 4-5 pm. On the second day of sun-drying, turn the ginger seed pieces over at noon. Dry them continuously for 3-5 days. When the outer skin of the ginger seed pieces becomes dry, whitish and slightly wrinkled, it means they have been dried enough.
Sprout promotion: After sun-drying the seed, carry out sprout promotion. Sprout promotion can prompt the young buds of the seed ginger to sprout as quickly as possible, resulting in fast and uniform emergence, so it is a very important technical measure. No matter which sprout promotion method is used, the seed ginger must first be pre-warmed. That is, on the last day of sun-drying the ginger, while it is still warm in the afternoon, select the seed ginger and bring it back, then pile it indoors for 3-4 days, with dry straw underneath and a straw curtain on top, keeping the temperature at 11°C-16°C to promote the transformation and decomposition of nutrients in the seed ginger, and then move it to the sprout promotion site for sprout promotion. There are two commonly used sprout promotion methods. The first is sprout promotion in a sun-facing bed. The sun-facing bed should be dug in a sunny, sheltered spot, running east-west, 60 cm deep and 1-1.2 m wide, with the length depending on the amount of seed ginger. Spread a 10 cm thick layer of wheat straw on the bottom of the bed. Place the seed ginger pieces one next to another with the bud eyes facing up on the wheat straw, then spread another 15 cm thick layer of moist wheat straw, cover the bed opening tightly with plastic film, and cover with a straw mat at night. During sprout promotion, the temperature should initially be kept at about 20°C, then gradually raised to 28°C, and must not exceed 30°C; the humidity should be kept at 75%-80%. After 7-8 days, when the ginger buds begin to swell, start ventilating and gradually lower the temperature to 20°C. In this way, under alternating temperature conditions, the young buds produced are plump and robust. After 20-25 days, when the ginger buds are 0.5 cm long, they can be sown. The second is sprout promotion in a greenhouse. After piling the sun-dried seed ginger in the greenhouse in the same way as above, cover it likewise with plastic film, and control humidity and temperature the same as for the sun-facing bed. After about 20 days, the ginger buds can all emerge.
Breaking into pieces: After the ginger buds have all emerged, first select whole pieces, then select buds and break them into pieces. Be sure to use plump ginger and do not use thin ginger. A whole piece of ginger weighing 0.5 kg should preferably be broken into 10-12 pieces, with only 1 strong bud kept on each piece. Generally, between Grain Rain and the start of Summer, when the 5 cm soil temperature is stably above 15°C, planting can begin.
Apply sufficient base fertilizer before planting ginger
Apply sufficient base fertilizer before planting ginger. Per mu, apply 20-30 loads of decomposed cow manure or other farmyard manure and 200-300 jin of plant ash, then mix with soil after application. After ginger sprouts, weed and loosen the soil promptly. Because ginger has a high fertilizer requirement during its growth process, it should be broadcast several times. Generally, about 10 days after full emergence, when the seedlings are 2-3 cun tall, apply a seedling-promoting fertilizer, with 20-30 loads of dilute human and livestock manure and 15-20 jin of potassium chloride or potassium sulfate per mu. When ginger has grown to 7-8 leaves, apply 20-30 loads of pig and cow manure per mu, or use decomposed farmyard manure as a tuber-promoting fertilizer. After application, cover the bed surface with soil to keep the soil moist, and combine with intertillage weeding to earth up the soil. The human excrement and urine or cake fertilizer used must be fully decomposed. Ginger is a potassium-loving crop and is sensitive to the effect of potassium fertilizer, so organic fertilizer should be increased and quick-acting potassium fertilizer should be applied more. For high-yield ginger cultivation, it is also required that after the seedlings grow to 1 chi, apply a mixed fertilizer of phosphorus and potassium at half a jin each per hundred holes. After 40 days, apply 2 jin of ammonium bicarbonate. In July-August, ginger tubers expand and enter the peak growth season. Every month, carry out intertillage weeding 2-3 times, and supplement fertilizer according to seedling condition, frequently earthing up to prevent the rhizomes from being exposed and affecting quality. At the start of Autumn, earth up the soil and combine with applying 1.5 jin of urea. Around the End of Heat, apply a ginger-strengthening fertilizer once more.
How to prevent rot and death in ginger leaves?
Control measures include: 1. If diseased plants are found, dig them out early, disinfect with quicklime, and prevent contagion. 2. Combined with ridging, increase the application of organic fertilizer and calcium, phosphorus and potassium fertilizers, and also add new soil and improve with borrowed soil. 3. Sun the ridges at the right time, and use 1000-1500 times diluted solutions of thiram, hymexazol or copper oxychloride to drench the roots. 4. Control water sources and prevent cross-irrigation and flooding irrigation. 5. Maintain field soil moisture, enhance soil permeability, drain and prevent turbidity, and reduce toxins.
