A Detailed Guide to Leek Planting Techniques and Management Methods
Leek is a perennial herbaceous plant of the genus Allium in the Liliaceae family. Many friends may not be very familiar with it, so today the editor will introduce leek planting techniques to you. Let's take a look together!
1. Leek planting techniques
Planting leeks requires arranging a suitable time, generally sowing in late spring and early summer. Keep the topsoil moist to facilitate seedling emergence. Clear away the residue of the previous crop and weeds, and level the land. When the heart leaves begin to grow, irrigate once, and loosen the soil when the topsoil is at a suitable degree of dryness and moisture. Just do a good job of intertillage and weeding, watering, and fertilizing.
2. Disease and pest control
1. The main diseases and pests of leek include gray mold, soft rot, red spider mites, onion thrips, and root maggots. Compared with other allium vegetables, leek has fewer diseases and pests, and in production it is mostly not controlled. In recent years, the harm from leek gray mold and root maggots has worsened. The symptoms of leek gray mold are similar to those of Welsh onion and Chinese chive gray mold. In the early stage of the disease, white spots appear on the leaves, and the leaf tips wither. When the disease is severe, gray-black mold can be seen, and rotting starts from the leaf tips.
2. Control methods: Increase ventilation to reduce humidity, especially after watering, ventilation should be carried out promptly. In the early stage of the disease, fumigation with gray mold smoke agent can be used, with a dosage of 250 grams per mu, fumigating once every 7 to 10 days, which can achieve a control effect. When the condition worsens, 50% carbendazim and 50% procymidone can be sprayed for control. Root maggot control can be carried out before planting and in the seedbed. During the seedling stage, spray 50% dichlorvos 2000 times dilution, or 2.5% deltamethrin emulsifiable concentrate 3000 times dilution.
