1. Soil: shallot has a great demand for the soil with good permeability and drainage. The heavy soil in the vegetable field at home is more suitable for planting. This kind of soil can make shallot absorb and grow better.
2. Water content: it likes wetness rather than drought, but it also needs more water. The amount of water should not be too much, the soil layer should not be too wet, a little bit wet, the amount of water must be controlled.
3. Nutrients: compost is OK when applying fertilizer at ordinary times. When applying fertilizer, it is not suitable to sprinkle fertilizer directly on the root of shallot. It will burn the root until it rots. Sprinkle it on the soil far away from shallot and turn it evenly.
4. Temperature: the temperature of its growth is about 10-25 ℃. I like the fresh environment. In summer, when it's hot, shade it to avoid the influence of too high temperature on growth.
1. Pruning: after a period of cultivation, the tip of the onion leaves will turn yellow. At this time, use small scissors to prune them to avoid all the tips turning yellow. When you grow up to be edible, cut off the top to be edible, and leave about 3cm of scallion at the bottom, then you can continue to grow.
2. Propagation: it is OK to propagate by sowing. First, turn the soil and then spread the seeds evenly on the soil. Sprinkle about one centimeter of soil on it, then cover it with plastic film for heat preservation. In about 30 days, you can see that there are sprouts
1. Leaf blight: the common disease of cultured shallots is leaf blight, which is easy to infect. Not timely prevention and control will make the leaves dry and die, with the dilution of carbendazim spray can have a good therapeutic effect.
2. Rotten root: if the water is too sufficient and the soil layer is too wet, the root will rot. In general, we should pay attention to the control of water quantity to avoid rotten roots.
1. How to store: the picked shallots will rot in a few days if not properly stored. You should dig a deep hole and plant the whole bunch of shallots in the hole. In this way, it is the same as replanting, which can avoid spoiling. When eating, you can drag one or two.
2. Edible or not: edible, spicy, scallion flavor, can be used as seasoning.
