Question 1: The best time to plant onion seeds depends on which place you plant? Shandong's climate is best planted with wheat! The main thing is still the market ！！！！

Question two: how to plant onion seeds to wait for the seeds inside to mature directly after the seed can be planted, but the second year should be divided into several halves of the seed

Question three: when the onion seeds ripe Black is ripe

Question four: onion seeds can be planted a few years onion seeds are ripe, can be sown, there is no dormancy, do not need to be catalyzed, but to seedling

The question is: the onion seed can be sown in the past few years, but it is not necessary for you to plant seeds.

Onion Seed (English) Fistular Onion Seed, source The species of Allium fistulosum L. in the family of Yasuriaceae. Born in the field. Produced throughout the country, with a larger production in Shandong.

Onion seeds need to be saved for a short period of time, pay attention to the preservation methods to ensure the quality of onion seeds:

First, pay attention to the sun drying nuisance moisture, storage in a cool, dry place, bags or cans of finished seeds are best to open the bag that is sown, otherwise the seeds are prone to dampness, the loss of germination rate very quickly.

Secondly, we should pay attention to the prevention of insect infestation, especially cowpea and other seeds are easily damaged by insects.

Third, to prevent rodent damage.

Question 5: How long will the onion seedlings Onion sowing is preferable to use the germination heat and germination rate of better seeds, using the year's new seeds or low-temperature library storage of seeds, the germination heat (5 days) should reach 30-50%, the heat rate (12 days) should be more than 80%. Appropriate period of seeding is mostly used for seed direct seeding, but when the sowing period is late, stay to first soak the seed to germinate and then wet sowing. With dry seed direct seeding, in order to speed up the progress of sowing, you can first start from the middle of the plot of two beds, start out patting fine mulch, placed on both sides of the plot of the outside of the bed. Apply a small amount of nitrogen, phosphorus, potassium composite fertilizer as seed fertilizer, the first to be sown in the middle of the two beds, deep hoeing, so that the fertilizer, soil mixing, cradling flat rake fine, put a small amount of water well watered, water seepage down immediately after the uniform sowing of seeds. Mu seeding amount of red 1.25-1.5 kilograms. After sowing the fine soil prepared in the beds on both sides of the sowing beds, use a shovel to cover the sowing beds, the thickness of about 0.5-1 cm, sowing, spreading the seeds to be uniform, covering the Gui thickness to be consistent. Sow the seeds in an orderly fashion until they are finished. 3-4 days after sowing, when the bed surface is slightly dry with cracks, the rake can be used to gently cradle the bumps and cracks on the bed surface, and at the same time, the ridge will also be cradled again. This can keep the nursery beds dry and wet, loose and solid, insulate moisture and prevent alkali, which is conducive to the emergence of full seedlings and seedlings. After sowing in the fall, generally 6-8 days to complete the seedlings. Spring sowing, due to low ground temperature, often slower seedling, need 15-20 days to come out all seedlings. Soak the seeds to promote germination is conducive to early seedling; can also be covered with plastic film. This can improve the ground temperature, but also early emergence, but when the cotyledons straighten out and into the removal of film, so as not to cause seedlings to grow. In order to prevent soil condensation, promote the emergence of seedlings, must be in the emergence of seedlings before the watering of a head. Seedlings after the cotyledons straighten before another watering, do not make the bed soil fall dry.

Question 6: when to harvest onion seeds in the fall, the seeds will become black and hard, this time to harvest, otherwise it will crack

Question 7: how to plant onion seeds? Mix it with the soil and spread it out in the ground, or dig a shallow trench, sprinkle the seeds in, and then cover the soil. Be sure to sprinkle water to keep moist, very easy to live

Question 8: How to sow seasonal scallion seeds? How many days after sowing the seedling? Buried very shallow on the good

Question 9: the home of the onion out of the seed planting techniques Autumn equinox diffuse sowing, before winter watering freezing water, spring warming water and fertilizer to keep up with, grow into the appropriate height of the trench transplantation, row spacing 80 cm, plant spacing of 3-5 cm double-row insertion of watering after the thorough watering. Every so often to cultivate the soil. Frost harvest

Question 10: how long to soak onion seeds. When planting onion seeds, do you need to soak the seeds? Do not need to soak directly sprinkled
