Ginger efficient and high-yield comprehensive cultivation technology
Ginger and garlic are the same seasonings commonly used in people's daily life. The main areas of ginger cultivation in China are mainly in Shandong and Sichuan. In recent years, the ginger market has not continued to be bullish. However, there are still many farmers who grow ginger, so how is ginger grown?
First, the site selection:
In the past two years, no ginger has been planted, the soil layer is thick, the water source is near, and the sandy loam is well drained.
Second, ginger selection and treatment:
Choose Leshan Xiba, Qufu for Xiaogu, Xinmin White Ginger. It should be selected that the epidermis is smooth, the bud color is normal, the rhizome is thick and fat, and there is no pest and disease. After the "rain water", choose sunny days, spread the ginger for 2-3 days, soak seeds with grass ash for 20 minutes.
Third, germination:
Before and after the "Spring Equinox", in the dam of Xiangyang lee, the bottom is 3-4 cm thick with straw, and then the grass is 10-13 cm, and then 3-4 cm stone flower. The ginger buds of the selected ginger species are piled upwards in order, 35-50 cm thick, and then covered with stone flowers, grass, straw 15-22 cm. Press around tightly, pour water, and use a membrane to cover the buds. When the temperature inside the stack is higher than 40 °C, the film should be uncovered and watered to cool down. Ginger buds are like peaches. The round and fat sturdy pieces are used. The standard buds are 2 cm long. Each 1-2 ginger buds are cut into a ginger piece, and the incision is stained with ash. Gingers that are not germinated or short in buds are placed in the heap to continue germination.
Fourth, as a construction:
Before and after “Lichunâ€, the concentration of human and animal manure with a concentration greater than 50% was used, and the amount of mu was 150. Deeply turn before planting, the soil is not thin, flattened, and the drainage ditch is surrounded.
The whole good ginger field is made into sorghum, and the ginger is built. The length of the oyster is 3.4-4 meters, the height is 25-34 cm, the base width is 26-30 cm, and the ginger groove is 10-13 cm wide. The ditch belt is 40 cm long and the back cover film is built.
Fifth, transplanting:
One week before planting, 5,000 kg of human and animal manure was applied as a base fertilizer into the ditch, and it was dried and not evenly distributed. Choose sunny day, put the ginger block in the ditch according to the distance of 7-13 cm, the ginger buds up, cover the ash or grass ash fertilizer (2500 kg per mu), cover the fine soil 7 cm thick, then drench the manure, and finally Cover with a membrane.
6. Field management:
Fertilizing soil
When the height of the seedlings is 13-16 cm, the soil is fertilized, and then every 15-20 days, 3-4 times, the fertilization concentration is gradually increased from 30% to 80%, and a small amount of potassium chloride should be added for each fertilization. It can also be used for external top dressing with 0.2-0.5% potassium dihydrogen phosphate. The soil is 3-7 cm each time. After the ginger is simmered, it should be loosened and dried, and then the soil is turned into ginger ditch. When Jiang Miao has not grown over Jiang Yan, he should continue to cover the film.
2. Drainage and shading
It is necessary to keep the drainage and communication smooth when there is too much rain. When the temperature is high and dry, the morning and evening, the application of light fertilizer water (concentration 10%) is drought-resistant, and it is necessary to cover the shade with a sunshade net, and cover it at night to cover the sun.
3. Pest control
(1) Jiang Yan: This disease often invades the leaves and roots, causing the roots to rot. The onset time is from June to August. It is found that the diseased plant should be removed as soon as possible, and the litter is sprayed with lime to prevent the ginger from filling the nest.
(2) Ginger and Helicoverpa armigera: application of crystal enemy white worm, hydrogen bromide and octothelin.
