The latest method of post-autumn management of leek

After the Beginning of Autumn really entered autumn, the temperature began to drop a little, the weather was more pleasant, and the temperature gap between day and night began to widen. This is actually beneficial to the growth of leeks, but it also needs to pay attention to many problems, such as the adaptation of temperature changes. There are other management problems. How to manage the growth of leeks after autumn is what we are going to introduce today.

1. Fertilizer and water management

At this time, vegetables grow rapidly and need a lot of nutrients, so they need topdressing, about 1500 jin of compost per mu, about 1500 jin of farm manure, and 50 jin of compound fertilizer. Used together, watering maintains the normal concentration of soil solution. Cold Dew should not water it in season, mainly to save up nutrition. The Beginning of Winter, need to cut off the withered leek, use 40 jin of urea per mu, combined with watering.

2. Darkening treatment

The Beginning of Winter gets rid of all the withered leaf weeds and needs to be darkened after watering and fertilizing. Build a small arch shed, in addition to the film, but also cover the grass curtain, and then open at 9 o'clock every day, grass curtain, and then cover it at two o'clock in the afternoon. Reduce the exposure to light every day, only about five hours. A week later, sprouting can uncover the film, cultivate the soil, and harvest when it grows tens of centimeters.

3. Governor hypnosis

Cold Dew will not water or top fertilize, accumulate nutrition and control growth. Frosts Descent later set up a northward tilt wind barrier in front of the south side, with a coverage of more than one meter high. Mainly in order to cool down, and then promote leeks into dormancy, but also to reduce nutrition consumption measures. After the winter cover, the wind barrier tilts to the south and begins to keep warm.

4. Disease and pest control

The main prevention of disease is root rot, after high temperature and rain, the base of the stem is prone to water-immersed disease, which will die slowly. Using 50% of nail cream copper wettable powder 500 times solution to root irrigation treatment, the spray treatment effect is not good. In autumn, the main control is drillworms, and the main food is pseudostem. Use pyrethroids to spray once a week, or other medication.

Leek after autumn is mainly based on the growth of some special management, such as darkening, control, hypnosis and so on. It is all for the management of nutrient accumulation and growth.
