First, select species
According to the different soil fertility status, the amount per acre is generally about 800 pounds. When selecting seeds, healthy and disease-free, uniform and consistent ginger mother and ginger seed should be selected.
Second, nurture strong buds
Sun ginger: 20-30 days before sowing, remove the ginger from the storage pit, wash the soil on the ginger, tile it on the grass or clean the ground for 1-2 days, and collect it in the house in the evening to prevent Cold. Its role is: 1, to increase the temperature of ginger block, to break the dormancy, promote nutrient decomposition in the body and speed up the ginger seed germination speed.
2, trapped ginger: After the sun ginger, the ginger will be placed on the indoor stacking 2-3 days, ginger pile covered grass rake, in order to facilitate the transformation of nutrients in ginger, early germination.
3, germination: generally use "Zu Jiang-bud" germination method, if the planting area is larger, more ginger species, can be used ginger ginger piled stack thickness should be controlled at 50-60 cm, the upper part of the ginger pile covered with quilts Or blankets, about 20-30 days, seedlings grow to 0.5-1.5 cm, you can sow.
Three, soil fertigation
After Jiang Tian was selected, 5000-8000 kilograms of high-quality rot-fertilizer and 50-75 kilograms of superphosphate per acre were applied to the ground and deep-turned 25-30 cm. After the leveling, open the planting ditch at a ditch of 50-55 cm. The ditch is 15 cm deep. Apply 25 kg of nitrogen, phosphorus and potassium compound fertilizer or 75-100 kg of cake fertilizer (used per acre) into the ditch, or boil and ferment. Good beans 50-75 kilograms, after the fertilizer is applied, mix the fertilizer and the soil with a two-toothed hook to prevent the water from being washed away.
Fourth, sowing
The open field cultivation is generally planted at the beginning of May and the ginger buds are graded according to size and size before sowing. When sowing is done, arrange according to the principle of Qi and Qi in the pre-made ginger ditch. The ginger shoots are upwards, the spacing between the plants is between 16 and 20 cm. Immediately after sowing, the soil is covered with a thickness of 4-5 cm. It is appropriate to swing the ditch. bottom. Overly thick soil and low ground temperature are not conducive to the emergence of seedlings. If the soil is too thin, the surface of the soil is easy to dry, which also affects the emergence of seedlings. After sowing is completed, pouring enough water, covering 1.1-1.2 meters of plastic film, so that the distance between the bottom and the top to maintain about 15 cm.
Fifth, fertilizer and water management
1. Watering: On the basis of pouring sole water, we should always keep the soil moist during the seedling stage to avoid the poor growth of the plant caused by the dryness and dampness, the short stature of the ginger seedlings, and the distorted state of the new leaves. Before and after the beginning of autumn, enter the vigorous growth period, the need for large amounts of water, generally once every 7 days or so water, keep the soil moist, pouring the last water 2-3 days before harvest.
2, top dressing and earth
On the basis of adequate basal fertilization, in the middle and late June of June, when the ginger seedlings are about 30 cm high and 1-2 branches occur, combined with the removal of the mulching top-dressing, the “submerged fertilizer†is applied, and ammonium sulfate or diammonium phosphate is applied per acre. 20 kg or so. Before and after the beginning of autumn, combined with weeding and topdressing “turnover fertilizerâ€, this fertilizer requires a large amount of fertilizer and has a full range of nutrients. It uses organic fertilizer with long-lasting fertilizer and fast-acting fertilizer to combine 75 kg of cake fertilizer per acre or 50 kg of fermented beans. 50 kg of compound fertilizer or 30 kg of diammonium phosphate and 25 kg of potassium sulfate. About 15 cm away from the base of the ginger plant, the ditch is ditched, the fertilizer is applied to the ditch, and then the cover ditch is ditched and the ridge is ridged, so that the original ditch becomes a ridge, a ridge ditch, and the water is timely watered after dressing. After entering September, in order to promote the rapid expansion of ginger blocks, “supplemented fertilizer†can be applied, and 10-15 kilograms of ammonium sulfate, 15-20 kilograms of potassium sulfate, or 25 kilograms of compound fertilizer per acre can be applied. Water rushes into the ginger field.
Sixth, pest control
1. Diseases: (1) Ginger disease: The prevention of soil and seed disinfection is used, and field control can be used: 50% thiobacillus 1000 times solution, 5 million units of streptomycin sulfate and 60 pounds of water (and neemectin), etc. The agent alternately sprays. (2) Anthrax: Field control is available: 80% of anthrax and 800 times of anthrax, and anthrax 800 times.
2. Insect pests: focus on prevention and control of ginger borers. From the beginning of June onwards, the use of Wan Ling, farmland music, extinction of Hezheng, Locust and other drugs are used alternately, and once every 7-10 days, it can be effectively controlled.
3, in order to promote plant growth robust, enhance disease resistance, during the growth period can be sprayed once every 10-15 days Kang Feng Su, love more income, big fat king and 2003, such as foliar fertilizer, and can be applied to the field of yellow rot Acid salt.
