How to Grow Shallots? A Detailed Guide to the Latest Planting Methods
Shallots are a relatively special vegetable, widely distributed in the northeast region of China. With a growth period of about two months, shallots have very high nutritional value. They can be used to treat insomnia, pharyngitis and other diseases, and can also lower the three highs, and now they are grown on a fairly large area in China as well. So how exactly should shallots be planted? Below, the editor will give you a brief introduction. Let's take a look!
1. Land preparation and sowing
First, we need to choose a suitable soil for planting, mainly a fertile, soft soil with strong permeability. Then do the land preparation work well: plow the soil about 30 cm deep, level and harrow it finely, then apply sufficient base fertilizer, mainly farmyard manure, supplemented by compound fertilizer. Shallots are generally sown after Qingming Festival, and the sowing method is mainly bed planting. Make the beds and dig the furrows, control the planting density well, and then plant. If using ridge planting, then you must first dig the ridges well, keeping the ridge spacing at about 60 cm.
2. Scientific fertilization
The root system of shallots is distributed relatively shallowly, so their nutrient absorption capacity is not strong and their drought tolerance is poor. Therefore, during the growing period of shallots, we must do a good job of topdressing to promote the growth of shallots, encourage the development of bulbs, and provide sufficient nutrients for shallot growth. We should carry out topdressing according to the growth stage of the shallots. For example, during the seedling stage of shallots, the topdressing fertilizer should mainly be ammonium sulfate and potassium sulfate. After the leaf emergence speed increases, appropriately increase the amount of fertilizer applied to improve the quality and yield of the shallots.
3. Reasonable watering
After sowing shallots, if the soil moisture content is relatively high, then there is no need to water, which can raise the soil temperature. If the soil moisture content is low, then watering should be done according to the actual situation. But be careful to control the amount of watering well, to avoid excessive water causing root rot and seedling rot. Then, when the bulb part of the shallots expands, appropriately reduce the amount of watering to encourage the seedlings to firm up; the firming-up period is generally about one week. As with topdressing, the amount and frequency of watering should be reasonably adjusted according to the growth stage of the shallots.
4. Pest and disease control
Pest and disease control for shallots is also very important. Common pests and diseases during the growth of shallots include downy mildew, onion thrips and so on. No matter what the pest or disease is, we should focus on prevention, and spray appropriately for disinfection about one week after seedling emergence; it is not suitable to do this on cloudy and rainy days. Spray different agents according to different pests and diseases. For example, downy mildew is generally treated mainly with chlorothalonil, purple blotch mainly with agricultural streptomycin, and onion thrips mainly with cypermethrin EC.
The above is a brief introduction to the planting methods for shallots. The planting methods for shallots are very simple, but they cannot be managed extensively either, otherwise it will also have a certain impact on yield and quality, so everyone must pay close attention. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
