Key points for the management of leeks over summer

1. Stop harvesting

Generally, harvest should be stopped from late June to early August to facilitate plant growth. The high temperature in summer will result in less nutrient accumulation and consumption of leeks, which will affect the plant growth, and the leaf tissue fiber will increase, the texture will be rough, the commerciality will be poor, and the growth will show the phenomenon of rest. Therefore, generally no longer harvest.

Second, prevent lodging

The summer weather is hot and rainy, and leeks more than two years old, if not cut in summer, the leaf height of the plant is prone to lodging, which seriously affects ventilation and light transmission, and is prone to disease. In order to prevent the leek from lodging and reduce the disease, the leek should be set up.

3. Picking in time

Because leeks consume a lot of nutrients when flowering and seeding, in addition to harvesting the fields, they should also be removed in time when the leeks are young and young, and cultivate healthy plants.

4. Strengthen fertilizer and water management

According to seedling condition, moisture condition and weather conditions, water is poured every 7 to 10 days, and the manure and urine and 3 to 7 kg of urea are applied with the water. It is best to apply bio-organic fertilizer of better quality.

V. Prevent and control diseases and insect pests in time

Pay attention to the prevention of blight. Summer high temperature or sun exposure after rain, prone to blight, can be used to prevent and cure root irrigation with 50% carbendazim 500 times solution. In case of heavy rain, pay attention to drainage and waterlogging and remove yellow leaves, maintain good ventilation between rows, and reduce disease. In case of drought, shallow irrigation with well water is required to reduce the ground temperature.
