1. Seed treatment

Chives seeds should choose varieties with high germination rate, excellent varieties and good disease resistance, and properly soak seeds before sowing, so as to properly improve the germination speed of seeds. 4-5 days before seedling, seeds can be soaked in warm water at 35 degrees Celsius, bad seeds and shriveled seeds can be removed during soaking, and the process of soaking seeds can be continuously stirred until the water temperature is cooled, and then soaked for about 24 hours. After soaking, the seeds are taken out, placed in an environment of 15-20 DEG C for germination, germinated in 2-3 days, and then sown.

2. Seed bed preparation

In the open field cultivation, seedbed should choose good drainage conditions, ventilation, irrigation conditions of the plot, before seedling to deal with the soil, on those tillage and fertilization treatment, application of decomposed farm manure 4000 kg per mu, there are conditions can also disinfect the soil.

Put the seeds into the hole, the depth should not be too deep, so as not to affect the emergence of seedlings, cover a thin layer of soil after sowing, and then pour a permeable water. Field sowing can be broadcast or field, seed row spacing at about 10 cm, depth control at 1.5 cm, watering after sowing.

4. Seedling management

Generally one week after sowing can emerge, the best temperature control during the emergence period, the seed germination temperature is 15-18 degrees, later with the seed germination, you can increase the temperature appropriately, the highest should not exceed 25 degrees. The light should not be too strong, in the autumn afternoon when the light is too strong, can be properly shaded, the substrate should be kept moist, should not travel drought phenomenon, in the seedling growth to about 30 cm when the foliar fertilizer 1-2 times, with 0.1% urea solution is appropriate.
