Ginger's Safe Production Techniques

1, selection. When selecting seeds, diseased ginger blocks with black or tan circles must be strictly excluded.

2, drying species. In general, in early March, the selected ginger seeds are sun-dried for 1-2 days in the sun, dried until the ginger peels dry and slightly crumpled, and the sick ginger blocks are removed.

3, germination. Before germination, use chlorothalonil, carbendazim and other fungicides to disinfect and sterilize, put in 20 ~ 25 °C local germination, relative humidity maintained at 75% to 80%, when the humidity is high, cover open air 1-3 days, about After 25-27 days, the seeds can be sown when the length of the shoots is 0.6-1.2 cm.

4, soil preparation fertilization. Deeply turn 18 to 24 cm, apply 4,000 to 5,000 kilograms of high-quality coarse fat per acre, and create a platform that is 35 to 40 cm high and 70 cm wide.

5, ginger seed. Ginger should be planted before the land is planted. Generally, only one short and strong shoot is kept on each ginger, and all other shoots are removed. The size of the ginger is about 75 grams.

6, sterilization. Axillary buds were sprayed with Rhizoctonia Mn-Zn, and 50 grams per 100 kilograms of ginger was used.

7, pouring water. Watering after sowing is completed after the sowing is completed.

8, sowing. April 10-20 appropriate sowing, planting 400-500 kg per acre, spacing between 20-22 cm. When sowing, the ginger seed should be placed flat in the ditch so that the bud orientation is consistent.

9, apply fertilizer. Mushi compound fertilizer 30 kg, 40 kg of potassium sulfate, 40 kg of trace elements or 2 kg of zinc fertilizer.

10. Disinfection. After sowing, the soil was disinfected with Rhizoctonia Mn-Zn.

11, cover soil. After sowing and disinfection, use a two-tooth hook to remove the wet soil from the upper part of the ridge, cover the ginger seeds, and then use the tweezers to flatten the soil. Generally, cover the soil 4 to 5 cm.

12, weeding. After covering the soil, follow the instructions to spray Shi Tianbu or Caicaotong.

13, covered. One is the method of mulching, that is to say, the ground film is laid on the ground, two channels are one, and so on. The second is the cultivation method of small arches. The first 90- to 100-cm bamboo pieces are arched into the ground and then covered.

14, ventilation. When the seedlings unearthed, according to the temperature conditions, timely rupture of membrane ventilation.

15, watering. After the Qi Qi Miao, the soil should see wet see dry, you should pour Qimiao water, after the timely watering, generally every 7 to 10 days, once during the growth period, should keep the soil moist, the top soil is not white principle. From August to September, it is a period of vigorous growth of ginger leaves and ginger, which must be often watered and watered before 8 o'clock in the morning. The rainy season must be drained to prevent the rain from rotting.

16, top dressing. The principle of fertilization is to lightly or not apply seedling fertilizer, reapplying branching fertilizer, and applying autumn fertilizer. Generally, in mid-July, a fertilizer is applied once every 25 to 30 kilograms of urea per mu; in early August, 75 kilograms of ammonium bicarbonate and 15 kilograms of compound fertilizer are applied per acre combined with earth; in late August, 50 kilograms of ammonium sulfate is applied per acre; September In the early days, when the plants grew to 6 to 8 branches, the rapid rhizomes were inflated. Nitrogen fertilizer, potash fertilizer, and trace elements were applied according to the growth of the plants. The upper part of the plant was subjected to foliar dressing every 7-10 days. Spray once, even spray 3 to 4 times.

17, earth. When the seedlings are 10 to 15 cm high and 2 to 3 stables, the membranes should be removed and the grass should be removed in time. The first time the earth is to be cultivated, a small amount of soil on the platform should be planted in the trenches, and the earth should be earthed once every 15 days. Co-cultivation soil 3 to 4 times.

18. Prevent disease. The main disease is Jiang Yan. Control methods can be implemented for crop rotation, selection of disease-resistant varieties and disease-free ginger seeds, water purification, application of net fertilizer, timely treatment of diseased plants. Timely removal of the diseased plants, lime in the points of the plant, chemical control can be used to kill 3000.

19, pest control. The pests of ginger are mainly borers, thrips, and root knot nematodes. The borers were controlled with 20% chlorantraniliprole and 5.7% methotrexate. Thrips are treated with 4% anti-influx, and underground pests such as root-knot nematodes can be controlled by avermectin and avermectin.

20. Harvest. Ginger is not tolerant of sub-zero temperatures and should be harvested before "frost." Harvest about 2 cm above the ground stem, remove the roots, at any time into the pit, do not need to dry.

It is forbidden to use tert-butyl phosphorus, carbofuran (carbofuran), phorate, aldicarb (Shennon Dan), and other national prohibited pesticides and pesticides containing forbidden pesticides on ginger and other vegetables. Use is illegal. behavior.
