It is necessary to understand the method of using chemical fertilizers for scallions, because if the rain is heavy and the humidity is high, the scallions are easily infected with root rot, soft rot, gray mold, etc., and the damage is serious. If the stalks are used in the summer, the biological fertilizer is used as the base fertilizer. 150 to 200 kilograms per mu, spread the biological fertilizer evenly on the land where the shallots are to be planted, and then plow the ploughs to make the biological fertilizer and the soil fully contacted and then planted.
After the operation of the shallots, every 15 to 20 days, the roots should be drenched once with 1500 times of the aqueous solution of the biological fertilizer, or 300 times of the root of the biological fertilizer, and continuously drenched 3 to 5 times, each time per acre. 2500 ~ 3000 kg, evenly drenched in the soil around the roots of the chives plant. In this way, the shallot will not be damaged by root rot, gray mold, soft rot and root-worm, no rotten roots and dead seedlings, green leaves, good growth and high yield.
