How is ginger grown? Cultivation techniques of ginger

How to plant ginger? Ginger has many functions in food and medicine. How to grow ginger? What are the planting techniques of ginger? How can we plant ginger well? Then let's take a look at the article on planting techniques of ginger, so that you can know more about agricultural science and technology. I hope it will be helpful to you.

How to deal with ginger before sowing

To dry the seeds, put the selected whole ginger seeds in a single layer on a sunny day and dry them in a leeward, sunny, dry and warm place. It will be opened at 8: 9 a.m. and withdrawn at 4: 5 p.m. The next day when drying again at noon, the ginger seeds will be turned over at noon, and the ginger seed coat will be dry, white and slightly wrinkled for 3 to 5 days in a row, indicating that it has been sunburned.

Promote budding after drying the seeds. Sprouting can promote the young buds of ginger to germinate as soon as possible and emerge quickly and neatly, so it is a very important technical measure. No matter what kind of germination method, the seed ginger must be preheated first, that is, when drying the ginger on the last day, the seed ginger should be selected and collected while it is hot in the afternoon, stored indoors for 3-4 days, covered with hay and covered with straw curtain, the temperature should be kept at 11 ℃ ~ 16 ℃, promote the transformation and decomposition of nutrients in the ginger, and then move to the germination place to accelerate germination. There are two common methods of sprouting. First, the Yang bed accelerates sprouting. The sunny border should be dug in the sunny leeward, east-west, 60 cm deep and 1-1.2 m wide, depending on the number of ginger species. The bottom of the bed is covered with wheat straw 10 centimeters thick. Put the ginger seeds one by one, the bud eyes up on the wheat straw, and then spread a layer of 15 cm thick tidal wheat straw, cover the border with plastic film, and cover the grass at night. During the budding period, the initial temperature should be kept at about 20 ℃, then gradually increased to 28 ℃, up to 30 ℃, and the humidity should be kept at 75%-80%. After 7-8 days, the ginger buds began to let out when they germinated and expanded, and the temperature gradually dropped to 20 ℃, so that the buds were enlarged and robust under the condition of variable temperature. After 20-25 days, the ginger buds can be sown when the ginger buds are 0.5 cm long. The second is to sprout in greenhouse. After the dried ginger seeds are stacked in the greenhouse with reference to the above methods, they are also covered with plastic film, humidity and temperature control are the same as the Yang bed, and the ginger sprouts can come out in about 20 days.

After breaking the ginger sprouts, first select the whole piece, and then select the buds to break into pieces. Be sure to choose fat ginger and ban lean ginger. For a whole piece of ginger weighing 0.5 kilograms, it is appropriate to break 10 to 12 pieces, leaving only one strong bud in each piece. Generally, after Grain Rain, before the Beginning of Summer, when the ground temperature of 5 cm is stable above 15 ℃, it can be planted.

Ginger should be fully fertilized with basic fertilizer before planting.

Ginger should be fully fertilized before planting. 2030 piculs of rotten cow dung and 200 kilograms of plant ash can be applied per mu, and mixed with soil after application. After ginger sprouts, it is necessary to weed and loosen the soil in time. Because of the large amount of fertilizer needed in the growth process of ginger, it should be spread many times. Generally, about 10 days after the full seedling, the height of the seedling is 2 to 3 inches, and 20 kilograms of sparse human and animal manure, 15 kilograms of potassium chloride or potassium sulfate should be applied per mu. When ginger grows to 7-8 leaves, 20-30 tons of pig and cow manure are used per mu, or rotten soil manure is used as promoting fertilizer. After application, cover the border with soil to keep the soil moist, and combine with ploughing and weeding to cultivate soil. The human feces, urine or cake fertilizer used must be fully cooked. Ginger is a potash-loving crop, which is sensitive to the effect of potash fertilizer, so it is necessary to apply more organic fertilizer and more available potash fertilizer. For high-yielding ginger, it is also required to apply half a jin of phosphorus and potash fertilizer per hundred holes after the seedling grows to 1 foot. After 40 days, 2 jin of ammonium bicarbonate was applied. From July to August, the ginger lump should be ploughed and weeded for 2 or 3 times a month, and the seedlings should be fertilized and the soil should be added frequently to prevent the rhizome from being exposed and affect the quality. To the Beginning of Autumn, it is necessary to cultivate the soil, combined with the application of one and a half jin of urea. The End of Heat applied ginger fertilizer again before and after.

How to prevent ginger leaves from rotting to death?

Prevention and control measures are as follows: 1. When diseased plants are found, they should be dug up as soon as possible and disinfected with quicklime to prevent infection. two。 Combined with ridge cultivation, the application of organic fertilizer, calcium, phosphorus and potassium fertilizer can also be used to assist new soil and guest soil improvement. 3. Timely drying ridges, using thiram, chlorpromazine, copper oxychloride 1000-1500 times solution to irrigate the root. 4. Control the water source and prevent the flood irrigation. 5. Maintain field moisture, enhance soil permeability, drain and prevent turbidity, and reduce toxins.
