So how to grow onions? The editor will give you a brief introduction below, let’s take a look!
1. Soil preparation for sowing
First of all, we need to choose a suitable soil for planting, mainly fertile, soft and permeable soil.
Then prepare the soil well, plow the soil about 30 centimeters deep, rake it flat and finely, and then apply sufficient base fertilizer, mainly farmyard manure, supplemented by compound fertilizer.
The sowing time of onions is generally after the Qingming Festival, and the sowing method is mainly in the border.
Make borders and dig stems, control the planting density before planting.
If it is ridge farming, then the ridges must be dug first and the ridge spacing should be kept at about 60cm.
2. Scientific fertilization
The root system of onion is relatively shallow, so its nutrient absorption capacity is not strong and its drought tolerance is poor.
Therefore, during the growth period of the onions, we must do a good job of top dressing to promote the growth of the onions, promote the development into bulbs, and provide sufficient nutrients for the growth of the onions.
We need to do a good job of top dressing according to the growth stage of the onions.
For example, in the seedling stage of onions, top dressing fertilizers are mainly ammonium sulfate and potassium sulfate.
After the leaf growth speed is accelerated, the amount of fertilizer should be appropriately increased to improve the quality and yield of green onions.
