High Yielding Cultivation Techniques of Scallion Exporting to Japan

The scallion exporting to Japan has high quality, high yield, strong adaptability. The key cultivation techniques are described as below: First, choice excellent seeds, and nurture robust seedlings. The common standards are like these: complete and compact plants, no pests, dark green leaf color, thick wax powder, fake stem is 40 cm in length, 2 cm in diameter, white and dense pulp.
2. Choose loose and fertile soil with flat terrain, good drainage and irrigation conditions. 3. Soak the seeds. Use new species, and 75g seeds per 667 m2. Soaking for disinfection is before sowing. 4. Sow. Keep the soil with enough moisture. When the seedlings are 40cm in height, stop watering and prepare for fix planting.
Second, give reasonable arrangements for annual cultivation. Export requirements of the balanced supply of green onions, Lu cultivation alone can not meet the export requirements, production facilities and to integrate the protection and achieve annual cultivation, the annual supply to meet market demand. General use in the spring of 2,3-winter breeding shed, Age 50 to 60 days, the colonization in the Shed, August harvest, or by the end of March, early April Shed small nursery, Age 60 to 70 days after planting to harvesting Lu, October harvest; late September may also reveal the nursery, natural winter, and in June the following year colonization in the open field, 9 to October harvest; 9 to October also small Shed nursery, Age 50 to 60 days, the colonization in the winter - The display of the following 3 to April harvest.
Third, pay attention to rational management of fertilizer and water. Use compost manure 2000 kg or 5000 kg, 50 kg of SSP, 50 kg of potassium sulfate fertilizer, borax 2 kg per mu. Remove the diseased plants, deformed seedlings and miscellaneous lines. Pay attention to ventilation when there is high temperature for a long time. Keep the soil enough moisture to keep the normal growth of the plants.
5, pest prevention. The scallions have less diseases and insect pests according to the good resistance to diseases. However, as export standards is high, we will use of the low toxicity of pesticide residues or natural botanical fungicide, and decline the use of chemical pesticides. 6. Timely harvest. Uproot the stems of scallions gently and avoid injure the fake stems or roots. Net the soil and preserve 4-5 intact leaves according to the standard classification acquisition. Processing the scallions as soon as they are shipped to the processing plants.
