What are the latest precautions for growing onions

When it comes to onions, surely none of us are unfamiliar with them. Quite a few people, when cutting onions, are moved to tears, because the smell of onions is just too pungent, yet their nutritional value is very high, and the taste is not bad either. Here the editor tells everyone that when cutting onions, dip the onion, the kitchen knife and your hands in water, so that cutting onions will not sting your eyes. However, what the editor wants to share with you today is some precautions for growing onions compiled by the folks at Qinnongwang. As for little life tips, you can follow us to keep learning about them.

1. Seed selection

When it comes to seed selection, everyone knows that you definitely need to choose high-quality varieties, so how do you choose? First, we need to understand the local onion growing situation, and see how the varieties they choose perform and whether the yield is high. Second, analyze the market to see whether growing this variety of onion is competitive. After choosing a good variety to grow, the next step is to screen out high-quality seeds from it. We mainly do this by observing whether the seed color is bright and glossy, whether the seeds are plump, and whether there are pests or diseases. If none of these problems exist, then it is fine.

2. Timing

Whether the onion planting time is chosen correctly has a huge impact on onion yield, so you must pay very close attention when choosing the planting time. Although onions can be planted all year round, if you want the onions you grow to be both high-yield and high-quality, then it is best to choose to plant in August or September. At this time, the temperature in most regions is around 20 to 25 degrees, which is the best time for onion sprouting and growth.

3. Watering

Before sowing, we must first water the land once to ensure soil moisture. Next, when the onions grow three leaves, they need to be watered. During the onion growing period, a certain amount of moisture is needed; it cannot be too dry, otherwise the onions below will not grow large, and the onions that do grow will have no moisture. Usually we water once every week, but note that in winter you absolutely must not water, otherwise the onions will rot.

4. Fertilizing

Fertilizing is a very important part of onion growing, so special attention is needed. If the wrong fertilizer is used or the amount is wrong, it will cause irreparable losses to onion growth. When conditions allow, it is best to mainly use farmyard manure or organic compost, supplemented with an appropriate amount of chemical fertilizer. On average, one mu needs about two thousand jin of fertilizer, of which the amount of chemical fertilizer is about three hundred jin. Next, onions need sufficient nutrients during the growing period, so we should apply additional fertilizer in appropriate amounts according to the growth condition of the onions, and at the same time choose what kind of fertilizer to apply as a top dressing according to the specific situation.

5. Pest and disease prevention

The most common pests and diseases of onions are downy mildew, damping-off, and the onion maggot. The control methods for downy mildew and damping-off are generally spraying with chlorothalonil or Bordeaux mixture, while for the onion maggot we can water the field, because the onion maggot is very afraid of water and will run away or even drown. Finally, trichlorfon crystals can also be used for control.
