Shed room vegetable problems solution

What to do with roots of seedlings?

If the ground temperature of vegetables is lower than 15°C for several days in a row, the amount of watering is large or long-term and rainy, the temperature of the seedbed is low, and the time for the seedlings to regenerate is long, the rooting phenomenon will occur. In the seedlings with seedling rooting, the above-ground leaves gradually appeared yellow-green or milky white from the bottom, and the leaf margins began to scorch, and the growth was extremely slow.

Measures: It can be prevented by adding organic fertilizer, applying bio-organic fertilizer, appropriate amount of watering, foliar spraying of foliar foliar fertilizer and other methods.

How to do with leaf filling?

During the growth of the sheds, if the air in the enclosed shed is high in humidity and the transpiration of the leaves is inhibited, the moisture absorbed from the roots and the moisture in the leaf cells cannot transpire, and water-stained bubble spots appear on the leaves, which may appear as downy mildew. And bacterial angular spot. If it lasts for a long time, the bubble patches will be blunt and the leaves will be green and will gradually turn brownish-brown with dead spots.

Measures: By increasing the temperature in the shed, properly ventilating and evacuating, spraying the antifreeze on the leaves, strengthening the insulation measures, adopting the method of early pulling and covering the straw curtain, and setting indoor temperature conditions, etc.

Climate is not suitable?

In the fall, the lighting time is shortened, and the temperature and light in the greenhouse cannot meet the normal growth needs of the shed. In the event of disaster weather, low temperature and low temperature, sudden drop in ground temperature, roots are inhibited, the vegetative growth potential is weakened, there is a phenomenon of stalks in the middle and lower culms, the upper stalk becomes thinner, the leaves become smaller, and the tendrils are weaker.

Measures: Prevention should be based on preserving temperature, can be opened shallow ditch coating, or cover 3 to 4 cm wheat straw, take micro-irrigation measures, can prevent sudden drop in temperature, reduce damage to the root system.

Improper ventilation?

If the shed vegetables planted in the autumn are neglected for ventilation and humidity management, the shed vegetables will appear wilting and grow slowly.

Measures: Wind and humidity should be taken into consideration. The time for air release is generally around 9:00 in the morning, half an hour for ventilation, and covered at night. In the wind and at the same time we must pay attention to scientific fertilization, to restore the weakness of shed vegetables, fertilization to take "a small number of times" approach to chase or hole application of quick-effect fertilizer, but also to grasp the shed temperature, reduce the shed inside the harmful gas is too concentrated.
