Ginger is a vegetatively propagated crop. In the long-term vegetative propagation process, many viruses are invaded and accumulated in the body, resulting in reduced yield, decreased quality, weakened stress resistance, and causing various diseases. Each year brings great importance to Jiangnong. Economic losses. Detoxification cultivation can improve the quality of ginger, reduce the incidence, and increase the commercial and economic benefits of ginger.
1. Fine soil preparation, formula fertilization. Select a soil with deep, fertile, well-performing, and slightly acidic soils. Disinfect the soil first, deepen the soil, and expose it to dry weather. Mushi lime 100 ~ 150 kg or enemy cough 1000 times disinfection. In combination with site preparation, high-quality, decomposed manure manure from 2,500 to 3,000 kilograms and 2000 kilograms of biofertilizer were used as base fertilizer per acre. {Jinmian Bio-fertilizer is the preferred choice for current production}
2. Carefully selected, suitable for early sowing. Use high-yield, high-quality, disease-resistant virus-free ginger species. About 30 days before sowing (film turf ginger before and after “convulsionsâ€), the detoxified ginger seeds from the pit were taken out and germinated. 7 days before sowing, wash away the soil, choose the sunny sun-seeding seed block for 1~2 days, make the ginger skin dry and whitish, select the big ginger block with good skin color and put it into the straw basket with straw, and head inwards , put the tails on the outer layers, cover straw or straw, tightly with a rope, placed in a greenhouse or a plastic greenhouse, the height of the ginger seeds is no more than 80 cm, keep the basket moist, germination temperature should be controlled at 21~ 25°C. After 20 days, the young shoots were taken out at a length of 1 cm and cut into small pieces, each with 1 or 2 buds. The wounds were sown with gold manure field fertilizer. Use 150-200 kg per acre. Ginger can be sown at the beginning of April by pregerminating or cultivating with plastic film, which is 15 to 30 days ahead of the conventional sowing date to extend the growth period and increase the yield. The herbicide was applied to the water before the film was covered to prevent weeds under the film. Appropriate planting can increase the yield per plant and promote large and neat ginger. Sowing methods are as follows:
1 sorghum cultivation. After the land is flattened, a ditch is made, the width is 1.2m, the ditch width is 30cm, and three planting ditches are evenly opened for each ditch. After applying the base fertilizer and the soil, the planting is carried out according to the spacing of 20 centimeters, and 6000 to 8000 plants are planted per mu. . This method is used on flat lands with high groundwater levels.
2 ridge cultivation. The land will be turned upside down and flattened, and no rakes will be planted. Baseline fertilizer will be planted in 50 cm intervals, mixed with soil, and planted at a plant spacing of 18 to 20 cm. Later, the soil will be used as a ridge. This method is suitable for terraces or slopes with low groundwater level and good ventilation and ventilation.
After sowing, cover 5-6 cm thick fine clay to make it emerge as soon as possible. Ginger can be planted in the sunshade, and the sowing date can be 1 month earlier than the open land, and the seedling emergence after the sowing is quick, the emergence of the seedling is good, and the growth period is long, which is conducive to high yield. The use of sunshade film to cover the protection in the later period, the harvest period can be extended by 15 days, but also conducive to increase production.
3. Scientific management to promote growth. Ginger is a shade plant. It is hi, damp, cool, and avoids hot sun. It can be shaded by shade nets 20 days after sowing, and can also be planted in rows of springs every 4~6 rows. Corn, which facilitates shading and field management.
1 Seedling stage. When the emergence of ginger reaches 80%, the combination of watering (depending on the situation of 5 to 7 days watering once), timely removal of weeds, cultivating 1 to 2 times.
2 seedling period. This period of soil moisture should be maintained at about 75% of the maximum water capacity in the field is appropriate (that is, there is a sense of moisture), seedling height 10 to 15 cm when the top-up seedling fertilizer, Mushi urea 10 ~ 15 kg; seedling height 30 ~ 40 There are 1~2 centimeters to catch the strong seedlings, 15kg of Mushi compound fertilizer or 250kg of dry cow dung and 75kg of plant ash (or 10kg of potash).
3 vigorous growth period. In combination with topdressing, you can use the proteoglycan liquid fertilizer to water, soil, soil every 15 to 20 days, a total of 3 to 4 times of soil, the planting will be converted into ridge rows. Depending on the sensation, water is poured every 4~6 days. When the seedlings are 50 cm high and 3~4 branches, the fertilizer is applied for the second time, 30~40 kg of potassium sulphate is applied, and 1000 kg of biological fertilizer is applied to the seedlings. The ditch is applied at 10 cm, and then the soil is cultivated. The soil will be cultivated on the side of the plant, each time the soil is 5-6 cm thick and the weeds are removed. During the root enlargement period, the topdressing was performed for the third time, combined with the application of potassium sulfate fertilizer and 50 kg of biological fertilizer.
4. Delay harvesting and increase production. The harvest of young ginger from Daejeon was harvested at the beginning of August. The best period of ginger was from the middle of October to the beginning of November. The yellow parts of the plants began to yellow, and the roots and stems were fully grown and matured. Ginger is harvested when the plants have 4 to 5 leaves in the middle or late June.
5. Control pests and diseases. In the appropriate period of pest control, low-toxicity and low-residue pesticides were selected for prevention and control. 1 ginger rot disease (Jiangyan). The diseased plants were immediately removed, and were sparged with 3000 times streptomycin sulfate. Each litter was filled with 0.5-1 liters. In the early stage of Jiangyan, spraying with 3% Kezikang WP 700 times or 80% Zinc 800 times, or spraying roots, spraying once every 7 days, spraying 2~3 times. Disinfection of lime in and around diseased nests. 2 ginger anthrax. Before the onset of multiple anthrax stages, 75% chlorothalonil WP was sprayed on a 1000-fold foliar spray; 70% thiophanate-methyl WP or thiophanate-methyl EC 1000x was used at the beginning of the disease. Interval 5 Spray once every 7 days, spray 2~3 times. 3 ginger spot disease. At the beginning of the disease, spraying Ning 500 times or Longke 80 times, spraying 7~10 days, and spraying 2~3 times. 4 Jiang Yan. Foliar sprayed with 1500 times Aviform salt + 3000 times the new buy Ling, 7 to 10 days spray once, spray a total of 2 times.
6 foliar spray. Foliar application of 99 plant protection can increase the disease resistance of ginger and improve the quality of ginger.
